It's bizarre how the Switch is fast becoming a platform for Jrpgs when it's previous successors were known for not even coming close to the genre, the number of entries of the genre would hardly hit double digits.
The Switch is inheriting Nintendo's home and handheld market. The DS and 3DS are JRPG powerhouses. Th Switch is just continuing that trend. Nintendo's home consoles didn't get many JRPGs after the SNES because of budget and competition. So the Switch being such a JRPG powerhouse it to be expected.
