Splatoon 2 is immensely popular in Japan. So popular in fact that residents build working models of the in-game paint guns, and host multiple events including holographic Callie & Marie concerts. The first Splatoondid very well for itself over there, but the low popularity of the Wii U didn’t help things.
Now with the Switch to assist in spreading its wings, Splatoon 2has soared over most of the Japanese games industry. According to Media Create, Splatoon 2has sold two million copies just in Japan. This figure might not seem like much given that so many games like GTA Vbreak records in the west, but over there it doesn’t happen all that often on consoles. (Portables are a different story, which have hosted several multi-million sellers.)
The last time that number was reached on a console in Japan was nearly a decade ago, back in 2010 with Wii Party(love that game!).
