I decided to take over my grandfather's restaurant when I was three years old," said Riri Nishioka, who became the second-generation owner at the age of 30, just as his grandfather started Tenwaka. I was a child of my grandfather since I was little, and I used to come to the restaurant often. I thought it was cool to see my grandfather making people happy with his cooking, and I would be happy if I could do that kind of work myself.

The course consists of eight dishes, including appetizers, soup, sashimi, seven kinds of tempura, vinegared dish, hot dish, rice, and dessert.

The dishes that always appear in a course include not only the tofu tempura and other specialties loved by his grandfather, but also avocados and other ingredients that were not used by his predecessor, as well as suggestions for marriages with Chinese teas. Because the restaurant has a long history spun by the love of the family, it is a place to visit on special occasions such as celebrations and anniversaries with your loved ones.
