This restaurant has a long history. One of its branches is right across from Kawaguchiko Station. It is very popular. I went there when it just opened at 11am today. When I came out at 12pm after eating, I was surprised to see a long queue at the door.
Generally, everyone orders Hoto from Yamanashi Prefecture, which is a bit like thicker udon noodles. The pot is very large. If you have a small appetite, two people can order one portion and some other dishes. There are vegetables such as cabbage, mushrooms, carrots, and pumpkin in the pot, but no meat. It is very warm to eat in winter~
The store sells various specialties, and there are also raw noodles that you can take home and cook yourself.
