Japan is getting a few games for the Switch launch that are releasing in America (I Am Setsuna) but will see a release in a few months down the line (Disgaea 5 Complete). However, the Switch is region free unlike the Nintendo Wii U or 3DS; you can play both at launch in Japanese with little issue! Some interesting news however is that both support English languages in the JP versions. What does this mean?
It implies you can play Disgaea 5 Complete in English language (not sure if the English dub is in the JP release) or import a physical version of I Am Setsuna from Japan to play on your NA account. This is great news and if you have a spare JP Nintendo Account, you add Disgaea 5 Complete to your launch shopping list.
