There are very few strict vegetarians in Japan,so it is hard to find vegetarian/Vegan restaurants in Japan.
I am not a Vegetarian, but I often go to Vegetarian restaurants.Because it is healthy, delicious, and reasonable. Its easy for me to enter a vegetarian restaurant alone since it has a relaxing atmosphere
