We stumbled on this place while walking around Takayama around lunchtime.
Two different lunch options were available. The basic and the premium.
The basic is priced at 1000 yen and the premium at excellent value at 1320 yen.
The premium lunch set included a range of vegan small typical japanese dishes including Salad, Hoto noodle soup (the local noodle type), pickles as well as some desert thing that I have no idea what it was (but it was good!). The lunch came with a caffeine free coffee and tea.
The place is run by two older Japanese women who were incredibly friendly, and did not speak English. However, we all got by with pointing, hand gestures and the English menu.
There are also store goods available.
Overall the food was overall quite good. The noodle soup was the stand out item.
Well worth the wander, if in the area, particularly as it is the only fully vegan operation in the area as far as I could tell. I would visit again, however it is closed on Sundays and Mondays, the only remaining days I am here.
