Kirishima Kokusai Hotel
forumWhat families say
Families and multigenerational groups praise the combination of the age-divided indoor kids park, the 64 sq m Kids Deluxe Room, and the variety of bathing spots such as the private-hire bath and the ganbanyoku (heated-stone sauna). Some guests report that at certain times of year the buffet is slow to restock when it gets crowded, and suggest going to eat early.
