Splatoon 2 sold 670,955 copies within its first three days of release in Japan, according to Famitsu numbers, making it both the biggest debut for a Switch title and highest selling Switch title to date. This number includes physical game copies, download cards, and Splatoon 2 Switch hardware bundles, but does not include digital sales.

Splatoon 2 launched for Switch on July 21.
