Talk about one hell of an attach rate! The Switch has moved over 1.5 million units in Japan, and the game of choice for most owners is Splatoon 2. At the very least, without knowing the official eShop download numbers, we can say that 73.96% of Switch owners in Japan have grabbed Splatoon 2. This sucker is going to be a long, looooooooooong tail seller for Nintendo!
