Mr. Tadashi Sumi
You will see a huge Ema (a votive horse tablet) displayed on the left wall.
A picture of horse running from outside the house toward inside is a lucky charm which is very popular in Hida area.
When you look around the comfortable size of restaurant, a frame displayed on the wall by the entrance catches your eye, too.
There is one sentence “eating will make people better” in the frame.
The same person who drew Ema writes this.
