Is Japan "irrelevant"?
7th-Gen Console Sales:
As a market, Japan is less relevant than either America or Europe, or the sum of other territories displayed as "Rest of World" on VGChartz.
"Oh, but Japan is more interested in handhelds, that's where they're truly relevant."
7th-Gen Handheld Console Sales:
Still a smaller cut of the pie than America or Europe. Not irrelevant, but certainly less relevant.
