Sales of the Nintendo Switch have continued to be successful in Japan. Famitsu released sales data for the week of March 19th, which resulted in the Switch selling 52,000 units. This means that, in Japan, the Switch has sold 4,037,144 units. Surpassing the 4,000,000 mark, the Switch managed to achieve this with the console at just 56 weeks old. Believe it or not, this is not far off from the Wii, which reached the same milestone in Japan just 54 weeks into the Wii’s life.
