About sea bathing in Oarai

Sea bathing in Oarai began in the Meiji period under the name of shiotoji, and Western-style sea bathing was introduced in 1887 as a change from medical care. Sea bathing became popular in the early Edo period as a health practice under Chinese influence, and in the Meiji period, Western medicine changed sea bathing from a medical practice to a leisure activity. Oarai also developed rapidly with the steamship service that began in 1883. A full-fledged beach was established in 1888.

Oarai Sun Beach has a long, sandy shore that is 1.2 kilometers long. The beach is ideal for families since it has shallow waters. With its history rooted in health practices dating back to the Meiji period, Oarai’s practice of sea bathing continues to attract leisure-seekers with its summer sunshine and azure sea. Enjoy the sea bathing culture of Oarai, which has been cultivated through its long history, and a moment on the beautiful shoreline.

About rip currents

A rip current is a very fast and powerful tide (mass of water). The bigger the wave, the bigger the rip current. Remember to not panic if you feel a pulling sensation on your legs or if you feel like you are being pulled hard offshore. The rip current diffuses and becomes a gentle current at offshore locations. Rip currents always weaken at some point. If you are not confident in your swimming ability or if you are tired, swim parallel to the shore while floating on the water’s surface without struggling. It will be safe to return to the shore after you escape from the rip current.

If you think you’re in danger

If you are in danger, wave your hands wide!

If you are in danger, wave your hands wide!
