	I successfully took my Amiga 1000 out to Japan (Tokyo) and had some
interesting experiences. 
	My major difference from your problem was that I have a PAL (UK) Amiga
so the problem with the tv/mains is all switched around. I have heard rumours
of only flimsy nature that there are parts of Japan that have a different supply
system to tokyo. However I am sure that the following is true in my apartment
in Tokyo. The mains voltage is 100v at 50hz, not 110v or 220v but 100v. The
100v supply has been known to work for some US equipment. It is easy enough to
get step up transformers for the job, where I was working we had about 20 
terminals all go down sick after a couple of months at 100v. Bolting on some 
step up transformers cured them!
	The tv system is the same as USA (NTSC) there would seem to be two 
versions but I never saw the NTSC 4.43 one in use, the other was something like
NTSC 3.14. My PAL amiga was a very early UK one that had a PAL agnus but NTSC
circuitry on the composite video, our world standard tv had no trouble adjusting
to 50hz 625line with NTSC colour encoding. I did however find a multistandard
RGB monitor (made by JVC).
	As for transporting the amigas I just wrapped mine up in my suitcase
(no monitor) with my clothes and prayed, no-one had been willing to insure it!
It arrived safetly and once I had it going it never gave me any trouble. 
	Hope this helps..
