A good beach, if you find yourself in Motobu, is highly recommended. Landscape, sand, everything is equipped.
But we were at low tide, probably, because the water level in the designated bathing area was very low. At the same time, it will not work to swim away: the floating fence line (buoys) goes into the sea very close. Going behind it is not an option: a valiant guardian-rescuer is sitting on the tower. We were standing in the water less than knee-deep, but as soon as we stepped over the buoys, an immediate warning cry was heard from the tower in our direction - go into the designated bathing area. At least laugh, at least cry, but the Japanese have safety first, you can't help it.
