"Famitsu report that the domestic Japanese videogame market is up 72.9% in 2017 from 2016 for hardware and 3.8% in software thanks to the success of the Nintendo Switch which was the best selling dedicated game system for the year with 3,407,158 units sold."

  1. Pokémon Ultra Sun Moon (3DS) 2,003,607
  2. Splatoon 2 (Switch) 1,752,096
  3. Dragon Quest XI: Sugisarishi Toki o Motomete (3DS) 1,744,603

  5. Dragon Quest XI: Sugisarishi Toki o Motomete (PS4) 1,336,180
  6. Super Mario Odyssey (Switch) 1,324,280
  7. Mario Kart 8 Deluxe (Switch) 1,103,744
