Also, be aware that DVDs and DVD players in Japan are Region 2, although they are NSTC. This means that you can play Japanese VHS tapes on a North American VCR (something you can't do with European VHS tapes), but you can't play Japanese DVDs on a North American player unless it's been hacked to be region-free.
In addition, FM radio in Japan is on lower frequencies than FM radio in North America, although AM radio uses the same frequencies. I go to Japan often enough that I've bought a little pocket-sized FM radio specifically for listening in my hotel room over there.
This is just something to keep in mind when you're shopping for electronics.
