Regional Software Shipments
Switch must be close to selling the most software of any platform ever in Japan with 175.08 million as of 30th September 2022.
From the fiscal year data it is easy to work out Calendar year software sales and compare to Famitsu which of course lacks digital sales.
Switch software shipments per year (Japan)
2017: 9.81 million
2018: 20.52 million
2019: 27.01 million
2020: 41.53 million
2021: 44.32 million
2022: 31.89 million from 1st Jan to September 30th.
2022 needs 12.44 million software shipments from 1st October to 31st December to be Switch's peak year and with Pokemon Scarlet & Violet contributing around half of that by itself it should easily happen.
