It seems that Japan's government revised its "Electrical Appliance and
Material Safety Law" back in April 2001, and added a stipulation that items
authorized under the country's old law (the "Electrical Appliance and
Material Control Law") couldn't be sold anymore, but granted those products
a five-year grace period. Well, if you check your convenient wall calendar,
you'll see that the five-year period is about to end, which means that as of
April 1, pretty much any electronic gear sold before April 1, 2001 can't be
legally resold in Japan.
