Last month (Sept 2017) Nintendo Switch stock level in Tokyo, Shizuoka and Osaka Bic Camera/ Yodobashi Camera outlets are zero for walk in purchase, after 6 months launching in Japan since 3 Mar 2017. The only method to get the console is via draw lot system on every Saturday.
But today (4 Oct, 17) we have some updates from Bic Camera, saying that Nintendo Switch is back on shelves on 27 Oct 2017, priced at 37970円, which is packed with Super Mario Odyssey game. Of course, the stock level in each outlet is different but we do expect early birds to get their Switch without drawing any numbers.
It seems that the Nintendo Switch stock supply in Japan is improving and getting back to normal very soon. Good luck for the buyers!
