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.
