Tokyo is a great place to get some hard to find japanese ingredients. The bento boxes are delicious and inexpensive. Store is clean and the workers are very friendly. They have a good selection of things that are difficult to find in the city like yuzu and ginko nuts and fresh shiso leaves, lotus root etc. They also have a good supply of sushi grade fish, gindara, kimche and other picked items like plums. Very good. it also happens to be right across the street from Umi which I can also say has excellent sit down food. Try the omekasi, you wont be dissapointed.
