Stay Two Nights in Atagawa: A Southbound 3-Day Izu Itinerary
If you are visiting the Izu Peninsula, changing hotels every night is not the only way to see more. A more comfortable approach is to stay in one hot spring town, leave your luggage in one place, and explore at a relaxed pace.
This two-night itinerary uses Futari no Yuyado Yubana Mankai in Atagawa Onsen as your base. Travel south toward Inatori, Kawazu, and Shimoda, while enjoying the coastal scenery and everyday life visible from the Izu Kyuko Line. Save Izu Kogen and the Jogasaki Coast for your arrival or departure journey.
Rather than trying to see everything, choose your destinations according to the season, weather, and transport conditions.

Day 1: Meet Izu through the train window
Travelers arriving from Tokyo generally travel via Atami before continuing toward the Izu Kyuko Line. Exact travel times and connections depend on the date and train service, so please check the official JR East and Izukyu information before departure.
The journey on the Izu Kyuko Line is not merely transportation. Look for the blue Pacific Ocean, small fishing ports tucked into coves, houses built on green slopes, fields, and local roads. Alongside the famous scenery, you can see the warmth of places where people actually live.
After arriving at Izu-Atagawa Station, leave your luggage at Yubana Mankai and take a first walk through the hot spring town. A station shuttle may be available between 2:30 p.m. and 5:00 p.m.; please contact the inn when making your reservation to confirm the current arrangements.
Look for steam rising from the onsen towers, lanterns glowing along the streets, and the sound of the Pacific Ocean. In the evening, warm yourself in one of the inn’s private onsen baths and enjoy dinner featuring local ingredients.
Day 2: From Inatori’s morning market to southern Izu’s landscapes
On Day 2, head south from the morning onward. We do not recommend rushing through Inatori, Kawazu, and Shimoda simply to check them off a list. Choose your destinations according to the season, your interests, and the day’s transport conditions.
Morning: Feel the atmosphere of Izu at Inatori’s Morning Market
If you are comfortable starting early, visit the Inatori Morning Market. The market features agricultural products, seafood, processed foods, and other local products from Higashiizu Town. It is a place to notice the food and human presence of a fishing town.
Official information lists the venue as the first floor of the Higashiizu Town Office multi-story parking lot and the hours as 8:00 a.m. to noon. Opening days and details may change, so please check the latest official information before visiting.
Late morning: Discover the wishes preserved in hanging hina dolls
If you visit Inatori in early spring, make time for its tradition of hanging hina dolls. Inatori is known as the birthplace of this tradition, which has been passed down since the Edo period.
Small handmade ornaments are displayed beside the hina-doll platform, expressing wishes for the healthy growth of girls. The tradition has been passed from mother to daughter and from daughter to grandchild. Each ornament reveals that travel in Izu is not simply about seeing things; it is also about encountering the hopes of local families.
Festival dates, exhibition venues, and admission details vary by year. Please check the official Higashiizu Town or Inatori Onsen information before traveling.
Afternoon: Kawazu Cherry Blossoms or a full day in Shimoda
During the Kawazu Cherry Blossom season, walk beside the Kawazu River and enjoy the famous early blossoms. Blooming dates and festival crowd levels vary each year, so check the latest official information before traveling. After Kawazu, return to Yubana Mankai without having to move your luggage into the busiest area.
Outside the cherry blossom season—or if you would like to travel farther south—make Shimoda the main destination for the day. Shimoda is not simply a seaside town. It is a place where volcanic landscapes, clear water, fishing-port culture, and the history of Japan’s opening to the world meet. The town is part of the Izu Peninsula UNESCO Global Geopark, giving the landscape a deeper story beyond its beauty.
For a nature-focused route, choose Ryugu Sea Cave and Cape Tsumeki. Ryugu Sea Cave is a remarkable sea cave whose roof has opened to create a natural skylight. A trail above the cave offers a different perspective, including a place where the landform looks heart-shaped. At Cape Tsumeki, enjoy the meeting of rugged coastal landforms, open ocean, and seasonal vegetation. These are places to experience with your eyes, but also with the sound of wind and waves.
For a history-and-townscape route, walk Perry Road and visit Ryosenji Temple. Perry Road follows the route taken by Commodore Perry’s party on their way to Ryosenji during the negotiations that led to the Shimoda Treaty. Along the Hirana River, the approximately 500-meter stone-paved street is lined with traditional Izu-stone buildings, namako wall patterns, willow trees, stone railings, and old-town details. In the evening, gas lamps give the street a particularly atmospheric character.
Ryosenji Temple stands at the end of this historical story. Nearby, the Shimoda Museum of the Black Ships, MoBS, and Chorakuji Temple offer further ways to understand the period when Shimoda became Japan’s gateway to international exchange. If you prefer to experience the modern life of the port town, visit Kaikoku Shimoda Minato or consider an Izu Cruise, subject to the day’s operating schedule.
If you travel as far as Shimoda, do not try to fit Ryugu Sea Cave, Cape Tsumeki, Perry Road, and every museum into one rushed afternoon. Choose a nature route or a history route, select one or two main places, and leave time to pause. In Izu, the journey itself takes time, and that is part of the experience. At the end of the day, return to Atagawa and enjoy the quiet atmosphere of Yubana Mankai.
Day 3: Enjoy an Atagawa morning, then explore the north on your way out
On your final morning, take a bath before or after breakfast, listen to the ocean, and reflect on the journey.
If your departure schedule allows, add Izu Kogen or the Jogasaki Coast as a stop on your way out. You can also visit the northern side of Izu on your way into the peninsula. Placing the northern scenery at the beginning or end creates a pleasant contrast with your southbound day. Always allow plenty of time to reach your train or other connection.
Practical advice for international travelers
Public transportation in Izu is less frequent than in Tokyo or Osaka. Check train and bus timetables, seasonal services, and possible weather-related changes before departure and again on the day of travel. JR East, Izukyu, and each attraction’s official website are the best places to confirm current information.
Markets, restaurants, and seasonal events may have limited opening days or hours. If the Inatori Morning Market, the hanging hina-doll exhibitions, or the Kawazu Cherry Blossoms are important to your trip, check the latest information before traveling.
At a Japanese ryokan, you may be asked to remove your shoes indoors, and meal or bathing times may be arranged in advance. If anything is unfamiliar, please feel free to ask the inn when booking or at check-in.
Do not rush through Izu—travel south from an Atagawa base
The Izu Peninsula is more than a collection of viewpoints. It is the ocean and human life seen from the Izu Kyuko Line, the local produce and seafood at Inatori’s morning market, the family wishes represented by hanging hina dolls, the geological story revealed by Shimoda’s landscapes, and the steam and hot springs waiting in Atagawa at the end of the day.
Futari no Yuyado Yubana Mankai is an adults-only ryokan with only 16 rooms. With six private onsen baths and a quiet atmosphere, the inn is part of the Izu experience itself—not merely a place between sightseeing stops.
Make the second day your southbound day, and enjoy northern Izu when you arrive or depart. By using Yubana Mankai as your base, you can keep your suitcase in one place and experience Izu at your own pace.

Beyond Hakone: A Vast Ocean-View Sea of Gold
When autumn arrives in Japan, many travelers immediately think of the famous pampas grass fields in Hakone’s Sengokuhara. However, located right here in East Izu, the Hosono Highlands (Hosono Kogen) offers a breathtaking landscape that dwarfs Hakone in both scale and beauty.
Imagine standing amidst a sweeping, boundless grassland where a crisp autumn breeze brushes past your face. As you open your eyes, your entire field of vision is filled with rolling waves of golden pampas grass, set against the sparkling blue backdrop of the Pacific Ocean. There is simply no other place where you can experience such an open, dynamic coastal highlands panorama.
Climbing to Mt. Misugi: The Reward of the Summit
To truly experience the magic of Hosono Highlands, we recommend hiking all the way up near the summit of Mt. Misugi.
While it requires a pleasant walk, the “satisfying fatigue” of climbing under your own power makes the ensuing view infinitely more rewarding. Looking down from the peak, the sweeping expanse of Sagami Bay paired with the shimmering silver-gold grass creates a deeply moving masterpiece of nature that washes away the stress of daily life.
Tip for travelers: Autumn in the highlands can be brisk. For a comfortable hike, we recommend wearing long sleeves, long trousers, and sturdy walking shoes.
Enjoying All of East Izu: Morning Highlands, Evening Atagawa
This magnificent autumn event is not just an attraction of Inatori; it is a collaborative celebration embraced by the entire East Izu region.
To truly savor East Izu, limiting your trip to just one town would be missing out. After enjoying the crisp, invigorating morning air among the highlands, we invite you to journey down to Atagawa Onsen for the evening.
Recharging Your Energy in Atagawa’s Powerful Onsen
After a day of active hiking and breathing in the crisp mountain air, your body will be ready to unwind. What awaits you at our inn, “Futari no Yuyado Yubana Mankai,” is the restorative power of Atagawa’s 100°C natural, free-flowing hot springs.
The pure, high-temperature waters we protect as Yumori (Hot Spring Guardians) wash away not only the physical fatigue of the hike but also the accumulated stress of everyday life. More than just relaxation, the potent energy of our springs revitalizes your core, filling you with fresh vitality for the days ahead.
Embrace the panoramic grandeur of nature by day, and surrender to the quiet intimacy of lantern-lit hot spring baths by night. Why not treat yourself to the ultimate East Izu autumn journey this season?

Where Festive Energy Meets Serene Luxury
Every year, Atagawa Onsen bursts into a powerful wave of excitement and historic tradition during the Ishibiki Dokan Festival—the town’s most anticipated celebration, honoring the legendary samurai and castle builder Ota Dokan.
The festival’s centerpiece is the hauling of massive, multi-ton stone pillars using thick ropes, where both locals and visitors pull together in unison. Conveniently, our inn, “Futari no Yuyado Yubana Mankai,” is located just a short walk from the heart of the action.
“I want to experience the festival excitement, but I also want peaceful, private time with my partner.”
If that is what you are looking for, Atagawa—and our intimate inn—offers the ultimate combination.
“When Everyone’s Hearts Beat as One, the Stone Moves” — A Former Samurai General’s Insider Tips
Not many know this, but I (the owner of Yubana Mankai) once had the honor of serving as a Samurai General (Samurai-Taisho) leading this very festival. Standing before the gathered crowd, inspiring everyone to give their all, and feeling that surge of collective energy is an experience I will never forget.
As a former Samurai General and a proud local, here is my top advice for experiencing the festival to its fullest:
1. Don’t just watch—join as a puller!
To truly feel the festival, you have to grab the rope. With the traditional cry of “Sore, dokkoi!”, tourists and locals become one team. The moment everyone’s timing and spirit align, the heavy stone suddenly glides forward as if by magic. That overwhelming sense of unity and shared triumph will give you goosebumps. It is so addictive that many travelers return year after year just to feel it again.
2. Savor the local street food and the grand finale of fireworks
Beyond the stone pulling, the streets come alive with local food stalls offering authentic regional delicacies. It is a wonderful chance to interact with the warm-hearted people of East Izu. And as night falls, the festival culminates in a breathtaking display of fireworks lighting up the night sky directly overhead. Experiencing that brilliant display in the crisp evening air, wrapped in the pleasant, satisfying fatigue of a day well spent, is pure magic.
From Festival Thrills to Private Sanctuary
After a day of cheering, laughing, and pulling alongside the community, you return to Yubana Mankai.
The moment you step through our doors, the vibrant energy of the festival gives way to profound, soothing silence. With only 16 rooms dedicated exclusively to adults, our inn offers six private hot spring baths where you can unwind together in absolute privacy.
Soaking in 100% natural, free-flowing hot spring water while sharing stories of the day’s excitement—this is the ultimate “festival journey” designed by those who know Atagawa best.
This season, come experience the perfect harmony of thrilling tradition and serene luxury at Yubana Mankai.

What’s Missing in Your Daily Life? The Luxury of Time Together
When “Being Together” No Longer Means “Connecting”
Days fly by in a blur of career demands and daily responsibilities. You leave home in a rush each morning, and evenings are consumed by chores and preparations for the next day. Before you know it, another day has passed without a meaningful glance or a real conversation.
Even when sitting side by side on the sofa, your eyes are often fixed on your smartphone screens. Though the physical distance between you is just inches, the emotional and conversational distance can feel vast.
“When was the last time we just sat down and talked about nothing and everything?”
If you’ve been feeling this way lately, it might be a sign that caught up in the rush of daily life, you are running low on something vital: quality time together.
From Sightseeing Marathons to Reclaiming Your Time
When planning a trip, we often fall into the trap of filling our itinerary with “where to go,” “what to see,” and “what to eat.” We rush from one famous tourist spot to another, snapping photos on a tight schedule. Of course, that can be fun too.
However, is a packed itinerary really what you need right now?
What we propose is a journey where the sole purpose is securing uninterrupted time for the two of you.
Sharing idle conversations in the car as the coastal scenery of Izu drifts by.
A quiet evening stroll hand-in-hand through a traditional hot spring town.
Savoring exquisite local cuisine in a tranquil, intimate space designed exclusively for adults.
A little detour away from the rush of sightseeing, with simply “each other” at the center of the journey.
Why We Want to Help You Reclaim Your Time
At “Futari no Yuyado Yubana Mankai” in Atagawa Onsen, we made the deliberate choice to be an adults-only ryokan with just 16 rooms. We do not have the bustling commotion of large resort hotels. Instead, we offer absolute tranquility and six private hot spring baths (貸切風呂) dedicated entirely to couples.
For couples and partners who are giving their all to everyday life, yet finding that time for each other has slipped to the back burner—we truly wish for you to spend time here with us. That is our deepest hope.
Whether you use the mist-filled privacy of our private hot spring baths to finally talk about deeper matters, or simply share lighthearted laughter just like you did when you first met—knowing that we can provide such precious moments for you is the greatest joy for all of our staff.
“You know, I’ve been thinking about this lately…”
“Remember when we used to…”
It doesn’t have to be anything profound. We want you to rediscover the simple warmth of listening to each other’s voice and sharing the same moment, just as you used to do. If you feel something is missing in your daily routine, please let us help you fill that space.
Will You Reserve Time for Two This Weekend?
“We haven’t had enough time for just the two of us lately.”
If reading these words brought your partner’s face to your mind, perhaps it’s time to step away from schedules and efficiency.
The sound of Atagawa’s ocean waves and the soothing warmth of our natural hot springs are waiting to gently restart the clock for the two of you.
It all begins with reserving time for just the two of you.

The Japan Expert’s Secret: Choosing Atagawa for Kawazu Cherry Blossom Season
Beyond the Blossoms: A Deeper Dive into Early Spring in Izu
From late February to early March, the Izu Peninsula bursts into vibrant pink with the early blooming Kawazu Cherry Blossoms. The tunnels of cherry trees along the Kawazu River are undeniably breathtaking. However, this spectacular beauty often comes with a price: **overwhelming crowds**. Especially on weekends and during peak bloom, Kawazu Town becomes packed with domestic and international tourists, making traffic jams and long queues at restaurants an unavoidable reality.
“I traveled all this way, only to be exhausted by the crowds…”
For the “Japan Expert” who has experienced such frustrations, we propose a smarter choice: **”deliberately staying in Atagawa.”**
Kawazu’s Vibrancy, Atagawa’s Serenity: A Tale of Two Charms
During the Kawazu Cherry Blossom Festival, Kawazu Town is alive with a festive atmosphere. Stalls line the streets, the aroma of local delicacies fills the air, and people exchange smiles under the cherry trees. This is, in itself, a wonderful experience of Japan’s spring tradition. However, with limited accommodation options in Kawazu, finding a quiet place to enjoy a meal might prove challenging.
In contrast, Atagawa Onsen, just a 10-minute train ride away, maintains a surprising tranquility during the same period. Escaping the hustle and bustle of Kawazu, the peaceful hot spring town offers a serene retreat, truly deserving of the title “adults’ hideaway.” At our inn, “Futari no Yuyado Yubana Mankai,” with only 16 rooms, you can enjoy special moments with your loved one without worrying about other guests.
Three Reasons Why Atagawa is Your Strategic Base
1. Unbeatable Access and Convenience
Atagawa serves as an ideal **”transit point”** for early spring sightseeing in Izu. It offers excellent access to major tourist destinations like Izu Kogen and Shimoda, with smooth train connections. Our inn is within walking distance from Izu-Atagawa Station, and a shuttle service is also available. The ease of travel, even with heavy luggage, is a significant advantage.
2. An Onsen Town Illuminated by Night
While Kawazu Town features illuminated night cherry blossoms, Atagawa Onsen boasts its own unique evening charm. The steam rising from the onsen yagura (hot spring towers) creates an ethereal atmosphere, and the soft glow of lanterns gently illuminates the cobblestone streets. After enjoying the magnificent Kawazu Cherry Blossoms during the day, you can stroll through Atagawa’s quiet and atmospheric hot spring town at night. This is the true essence of staying at a Japanese ryokan.
3. The Ultimate Private Space at “Futari no Yuyado”
Our inn embraces the concept of “Adults-Only, 16 Rooms.” This is our **”commitment”** to ensuring our guests can truly relax and cherish their time with their loved one. After sharing the breathtaking beauty of the Kawazu Cherry Blossoms, imagine soaking in a free-flowing hot spring in a private space, undisturbed by anyone, and savoring dishes made with fresh local seasonal ingredients. Isn’t this the true luxury that a “Japan Expert” seeks?
Conclusion: Discover Your Own Spring in Izu, from Atagawa
The beauty of Kawazu Cherry Blossoms is universally acknowledged, but to avoid the crowds and experience Izu’s spring more deeply and comfortably, making Atagawa Onsen your base is the “Japan Expert’s Secret.” While a lively festival atmosphere is enjoyable, sometimes a quiet, luxurious journey spent with a loved one is even more special.
This Kawazu Cherry Blossom season, why not discover your own unique spring in Izu from “Futari no Yuyado Yubana Mankai” in Atagawa Onsen?

The Heartbeat of the Earth
As you step off the train at Izu-Atagawa Station, the first things that greet you are the towering wooden structures known as Yagura (onsen towers) and the plumes of white steam rising toward the sky. This striking landscape is a constant reminder that the hot springs we enjoy are, in fact, the raw “roar of the Earth.”
The Zen of Facing 100°C Springs
That rhythmic “clank, clank” sound you hear in the morning is the sound of Gensen-soji—the cleaning of the spring source. Over time, mineral deposits called Yunohana (snowy flowers of the hot spring) build up inside the pipes. To keep the water flowing, these deposits must be cleared away manually.
Working with water and steam that reaches nearly 100°C (212°F) is a dangerous task where a single mistake can be life-threatening. When we asked our Yumori (Hot Spring Guardians) what they think about during this intense work, their answer was simple: “Mushin” (Clear Mind).
“We simply focus. If even the slightest unusual sound mixes with the rhythm, it is a sign of danger or a malfunction. We sharpen our five senses to listen to the Earth’s mood, ensuring the safety and abundance of the spring.”
A Gift from the UNESCO Global Geopark
The Izu Peninsula is recognized as a UNESCO Global Geopark—a “gift from the southern volcanoes.” In Atagawa, where columns of hot water erupt high into the air, you can feel a sense of awe toward the natural energy that surges forth without any human intervention. It is not just “hot water”; it is the life force of the Earth, delivered to us across tens of thousands of years.
Beyond Relaxation: Receive the Energy
At Yubana Mankai, we pride ourselves on the “Freshness” of our springs. We pour the high-temperature source directly into the baths without adding extra water to cool it down. This is our commitment as Yumori: to deliver the Earth’s energy to you in its purest, most undiluted form.
We believe that an onsen should be more than just a place to relax; it should be a place to recharge your spirit with the energy of the planet. When you leave our baths, we want you to feel more than just “refreshed”—we want you to feel a surge of new vitality, as if you have touched the very pulse of the Earth.
The Courage to be Different
“Why only two guests?”
In the world of Japanese hospitality, where large hotels compete for mass crowds, we chose a different path. As a small, 16-room ryokan in Izu-Atagawa, we knew we couldn’t—and didn’t want to—be everything to everyone. To survive and thrive, we had to “sharpen” our focus. We decided to become a sanctuary exclusively for those traveling in pairs.
A Difficult Choice, A Firm Commitment
We sometimes receive inquiries from guests who wish to stay with their entire family. Each time we must decline, our hearts are filled with sincere regret. To those families, we are truly sorry.
However, we remain firm in this commitment. We believe that by focusing exclusively on “two,” we can protect a level of silence and intimacy that is impossible to find elsewhere. We want to dedicate our full energy to those who resonate with this philosophy—those who seek a rare escape from the noise of the world.
Your Time Together, Your Way
At Yubana Mankai, there is no right or wrong way to spend your time. If you are usually too busy to even share a meal, you don’t need to force a conversation. Simply being in the same space, watching the steam rise from the towers, and listening to the rhythm of the waves is enough. This shared silence is a beautiful beginning.
If there is something you have long wanted to say, or a special anniversary you wish to celebrate, let this be your stage. Our role is to provide the “calm”—an invisible luxury where you can truly face each other without distraction. With only 16 rooms, our staff is dedicated to tailoring every moment to your unique journey.
A Scene Etched into the Heart
As you wander through the streets of Atagawa, you will feel the gentle mist of the hot springs and the salt in the air.
“It may not be a world-famous grand vista. But it is a scene that will be etched deeply into your heart.”
The town itself is a stage for your retreat. The quiet atmosphere here naturally deepens conversations and slows down the ticking of the clock.
Beyond “Refreshing”
When our guests check out, we are happy when they feel refreshed for the week ahead. But we hope for something more. We hope they leave thinking:
“It was good to spend this time just the two of us.”
“I want to travel with you again.”
In the rush of daily life, it is easy to forget the simple joy of being together. If your bond feels just a little closer than it did yesterday, then we have fulfilled our purpose as “Futari no Yujuku”—The Inn for Two.
Preparing for Your Stay: Top 10 FAQs
Visiting a traditional Japanese Ryokan for the first time can be exciting, but you might have a few questions. At Yubana Mankai in Izu-Atagawa, we welcome guests from all over the world every day. Here are the top 10 questions we receive from our international travelers.
1. Are tattoos allowed in the hot springs?
Yes, absolutely! We have 6 private hot spring baths (Kashikiri) that are free of charge. Since these are private spaces for you and your partner/family, you can enjoy the onsen without worrying about tattoos at all.
2. Do I need to reserve the private baths?
No reservation is required. You can use any available bath whenever you like. Just lock the door from the inside and enjoy. Feel free to try all six different baths during your stay!
3. Can you accommodate vegetarian or allergy-free diets?
Yes, we can. Please let us know at least 3 days before your arrival. We can prepare menus excluding meat or specific allergens. For strict dietary requirements (like complete removal of Dashi/fish stock), please consult with us in advance.
4. How do I get there from Tokyo?
The easiest way is the “Limited Express Odoriko” train from Tokyo Station. It takes about 2 hours and 15 minutes directly to Izu-Atagawa Station. Our ryokan is just a 3-minute walk from the station.
5. Do you offer a shuttle service from the station?
Yes, we provide a free shuttle service to and from Izu-Atagawa Station between 14:30 and 17:00. Once you arrive at the station, please give us a call at 0557-23-1133, and we will pick you up immediately.
6. Can I leave my luggage before check-in?
Of course! You can drop off your bags at the front desk. Feel free to explore the beach or the town’s iconic steam towers while you wait for your room.
7. Are children allowed to stay?
To maintain a quiet and relaxing atmosphere for couples, we are an adults-only ryokan (12 years and older). We appreciate your understanding.
8. Does the staff speak English?
Yes, we have English-speaking staff members. We also use translation devices and provide English information guides to ensure smooth communication.
9. What time is dinner served?
Dinner usually starts at 18:00 or 18:30. We will ask for your preference during check-in to ensure your Kaiseki meal (featuring local Kinmedai fish) is served at its best.
10. Are there convenience stores or restaurants nearby?
There are small shops and local restaurants near the station. However, most close early in the evening. We highly recommend booking a plan that includes dinner to fully enjoy the local cuisine.
The Heartbeat of the Earth: The Steam of Atagawa
As you step off the train at Izu-Atagawa Station, you are immediately greeted by towering plumes of white steam rising into the sky. Scattered throughout the town are “Yagura”—wooden and steel towers that stand as monuments to the Earth’s energy. This is the identity of Atagawa Onsen.
But behind this serene view is a relentless battle with nature, led by the masters of heat known as the “Yumori” (Hot Spring Guardians).
“I Can Hear the Spring’s Mood”
In the quiet of the early morning, long before the first guest wakes, our Yumori listens to the rhythm of the towers.
Voice of the Yumori:
“Do you hear that rhythmic ‘clank-clank’ echoing from the tower? That’s the sound of strength. It means the spring is healthy and ready to flow today.
That sound comes from ‘Gensen-soji’—the essential task of scraping away mineral deposits (Yunohana) from the pipes. We must do this every three days, or the 100°C steam and water will clog the system. It’s a dangerous job, facing scalding heat and pressure, but as long as that sound echoes, the heart of Atagawa continues to beat.”
The springs in Atagawa are exceptionally hot and powerful. A Yumori’s job is not just maintenance; it is an art of adjustment. They read the daily temperature, the volume of the flow, and even the direction of the wind to calculate the exact timing for filling the baths. This ensures that every drop of water reaches our guests at the perfect, soul-soothing temperature. It is a level of craftsmanship that no machine can replicate.
Recognized by the World: The UNESCO Global Geopark
The Izu Peninsula is a designated UNESCO Global Geopark, recognized for its unique geological history. Within this framework, Atagawa is celebrated not just for its water, but for its “Yumori Culture.”
The tradition of managing 100°C volcanic springs using these iconic towers and sharing this energy with the entire community is a rare cultural heritage. When you soak in our baths, you are not just relaxing in hot water; you are connecting with the “Heat of the Earth” nurtured over tens of thousands of years, and the “Human Spirit” that has protected it for generations.
Soak in the Masterpiece
All six private baths at Yubana Mankai are prepared daily by our Yumori. When you feel the gentle, mineral-rich heat against your skin, remember the clanking sound of the early morning and the century-old towers standing tall in the steam. This is the authentic, raw energy of Japan.
The Heartbeat of the Ocean: More Than Just a View
When you open the windows at Yubana Mankai, the first thing you hear is the rhythmic pulse of the Pacific Ocean. Just a 1-minute walk from our doorstep lies Atagawa YOU-YU Beach—the only sandy beach in the Eastern Izu area and a proud recipient of the “AA” water quality rating (the highest possible grade in Japan).
But have you ever wondered why this beach remains so pristine and safe? The answer lies in the passion and pride of the local community.
Meet the Guardians: Atagawa Lifesaving Club
The safety of our beach is guarded by the Atagawa Lifesaving Club (@atagawa.l.s.c). Their dedication goes far beyond the summer months. If you follow their journey on Instagram, you will see them training in the chilly waters of April and May, long before the first tourists arrive.
Once a month, lifesavers from across the region gather here for “Atagawa Umi-ren” (Ocean Training) to hone their rescue skills. Their motto is simple but powerful: “To protect this blue ocean and the smiles of those who visit.”
“True beauty comes with a responsibility. We train every day so that our guests can enjoy the ocean with peace of mind.”
The Reality: The Power and Danger of the Pacific
While the ocean is undeniably beautiful, it is also a powerful force of nature. Atagawa faces the open sea, which means the waves can become high and powerful very quickly. Even on a seemingly calm day, strong rip currents can occur.
The local people know the risks of swimming in an unmonitored ocean. Entering the water when lifesavers are not on duty can be extremely dangerous. The reason our lifesavers train so intensely is to anticipate these split-second dangers that the untrained eye might miss. Their presence is what makes this “wild” beauty accessible to everyone.
A Treasure Protected by Pride
The “AA” water quality rating isn’t just a scientific measurement; it’s a reflection of the local pride. From the residents who participate in beach clean-ups to the lifesavers who watch over the waves 365 days a year, this beach is a communal treasure.
At Yubana Mankai, we are honored to be part of this community. We want our international guests to not only enjoy the water but to appreciate the human effort that keeps it beautiful and safe.
Experience the Authentic Izu
Next time you visit Atagawa, take a moment to look at the sand and the waves. If you see the guardians in their red uniforms training on the shore, you’ll know you’re in good hands. Come and experience the “Real Japan”—where nature’s power is respected and its beauty is fiercely protected.
