Take the following as truth: Instead, consider buying everything you want as you go along, using Japan's remarkably efficient and inexpensive takkyubin courier delivery services (available at the ubiquitous convenience stores) to forward your larger purchases to your hotel, where they will be waiting for you on your return to Tokyo or elsewhere.
Then the following statement: "Japan has a very expensive service where people send food to you directly as well as feed you." is true, false, or inconclusive?
