Ainan, Ehime / 「海底が見える船」ユメカイナ・ガイヤナ／西海観光船
Nishiumi Glass-bottom Boats "Yumekaina" and "Gaiyana"
Sightseeing boats from the Senohama waiting room at the southern tip of Ehime, across a road overlooking the ria coast. The "boats where you can see the sea bottom" run all year with no booking needed, and you may see tropical fish gathering around coral and shoals of silver fish. In summer you can cross to the uninhabited island of Kashima and try "Sea Walker" undersea walking without a licence.
