Ebay in Japan is not so famous.
Unfortunately, there’s very few seller, and no price competition and so, it’s a not good idea to find items in ebay Japan if you were looking for Japanese items.
Some domestic auction sites / shopping sites are very famous among Japanese people, such as Yahoo auction, Rakuten auction, rakuten, zozo, muji, uniqlo….
And most of them are not shipping items to overseas.
also, most of the Japanese can’t speak English, so we’ll help you buy from Japanese popular auction site, such as Yahoo auction / Rakuten auction / MBOK… etc.
