This is one of several self-contained studio rooms in a building next to Hisao’s kendo school. It’s basic, with a small toilet, but enough for a quick stay. The location is a 12-15 minute walk to a few metro train stations with plenty of convenience stores and restaurants (as wells as the famous Nippori fabric street) nearby. Hisao responded to all queries very promptly and was kind enough to let me check out late. Also his wife makes great breakfast sandwiches every morning!
