Hamanasu Marine Park, which signed a partnership agreement with Kesennuma City in March of this year, will finally open its Hoyaboya Room this June!
The room that will be transformed into the Hoyaboya Room boasts a spectacular ocean view, with the beach and horizon of Otani Coast stretching out before you. From the moment you open the door, you'll feel as if you're embarking on an adventure into the ocean where Hoyaboya lives, together with him.

From small children to adults, everyone can enjoy a special and exciting time as if they were traveling with Hoyaboya.
