The Japanese market is an odd one. They sell differently in the Home Islands than elsewhere.
It's not until the recent opening of the market that we get to take advantage.
By example, a 1/16 Tamiya RC Full Option kit generally runs about $100 less in Japan and includes a radio, receiver, battery and charger. The batt and charger are no great shakes, but the Futaba Attack Tx/Rx is worth about $150. If you buy the same kit outside of Japan, you get a big empty spot in the box, but the instruction still tell you how to set it up, just to rub it in. Once a Japanese HS opened up for overseas sales, even with the $90+ EMS 2nd day air, you still come out way ahead.
Second example, the latest Iwata AB I bought was a HP-TH. In the States it's called a Kustom, sold in a fancy metal case with a grip moisture trap. When I was looking, the best price was well above $400. Ordered the exact same brush from Japan, minus the metal case and moisture trap...$147 shipped. Yeah the manual is in Japanese, but who cares?
So, if my son and I went to Japan, we'd be coming home with bags stuffed with Bandai, Iwata, Anime, etc.
