Not sure if anyone has done this yet, but if you add up all the shipment+digital sales for Breath of the Wild in Japan for each fiscal year, it comes out like this:
FY 03/2017 - .51 million (.39 on NSW; .12 on Wii U)
FY 03/2018 - .70 million
FY 03/2019 - .47 million
FY 03/2020 - .45 million.
That all adds up to 2.13 million. (2.01 million on Switch alone). This makes Breath of the Wild the first Zelda game of all time to pass 2 million units in Japan.
