You may want to have some of your family in Japan check on prices there for some of the items you wish to purchase. Generally speaking, for any item that is readily available here in the U.S.A., it will be less expensive here than in Japan (sometimes much less expensive, especially at the two major stores in New York City). For those items that are difficult or impossible to obtain here, then Japan is the likely source.
When in Tokyo I just love to go to "Yodobashi Camera", located in the Shinjuku district, and salivate over the many floors of photo items.
Good luck in your quest, Kiku
