Hotaru is a buffet restaurant offered by Ume-no-Hana, a tofu and yuba kaiseki restaurant chain.
It takes about 10 minutes by cab from Kanzaki Station.
The restaurant opens at 10:30 and closes at 16:00, which means it is for lunch. If you go at 12:00, you will have to wait for quite a long time. It is recommended to have a light breakfast and go there in time for the 10:30 opening.
As you can see in the picture, there are many kinds of Japanese food available and all are delicious. Especially, the apricot bean curd is a must.
