Japan yahoo auction is the largest trading floor of Japan, comparable with the ebay.com auction. Any goods and to destination, and on quality, i.e. both clothes, and cars, and new goods, and second-hand are on sale. Naturally, are on sale not only Japanese brands, but also all others.
Independently it is possible to participate in the auction only through the intermediary sites since Yahoo Japan auction demand to have the account in Japanese bank. And sellers don’t ship goods outward, and for payment often don’t accept plastic cards and paypal, not to mention that the auction site on Japanese.
