About this spot

Swimming can be enjoyed for free, and with paid showers, changing rooms, restrooms, a shop and a rest area in place, plus lifeguards on duty, it is a beach where even families with small children can spend the day with peace of mind. With the clear water and open sand typical of the Sanriku coast (三陸), you can savor the afternoon at a leisurely pace, from playing at the water's edge to playing in the sand. Top up on light snacks and drinks at the shop or cool off in the rest area, and enjoy the sea right up to the 16:00 close.

Season & hours

Tips

Swimming is free, but the showers and changing rooms are paid, so having small change is reassuring. The sand gets hot during the day, so beach sandals are essential. Swimming hours end at 16:00, so allowing time to change and wrapping up about 15 minutes beforehand is recommended. Lifeguards are on duty, but do not take your eyes off small children even at the water's edge.

Best time to visit

The afternoon from 1 p.m. has good sun and lets you enjoy plenty of sea bathing until the 16:00 close
