Pikmin has never been one of Nintendo's major franchises in terms of units sold, but it's nice to know that the most recent entry – Pikmin 3 Deluxe – has found some degree of commercial success in Japan.
Total physical sales of the game – which is an update of the Wii U original – in Nintendo's homeland now stand at 513,225 copies, which means the Switch title has out-sold the original GameCube Pikmin, which achieved 502,996 sales during its entire lifespan but was later re-issued on the Wii.
By way of contrast, the original Wii U version of Pikmin 3 only managed to shift 232,313 units in Japan.
Here's how each Pikmin title has performed in terms of physical sales in Japan:
1. [NSW] Pikmin 3 Deluxe – 513,225
2. [NGC] Pikmin – 502,996
3. [NGC] Pikmin 2 – 483,027
