It turns out that Splatoon has become a big hit in Japan and copies of the game are currently very scarce indeed. The Kyoto based company has taken to Twitter to apologise for the situation and promises that more copies of the game will be available to purchase sometime next week. The company also advises that people who want the game should consider purchasing it from the Wii U eShop.

Splatoon has become scarce in the stores, and we apologize. Next week, but additional shipping, hurry please consider also purchased the download version. Also will add production amiibo splatoon are in short supply. Will be charged while your time here, but thank you for your note.

Thanks, Kallum
