The highest selling type of anime Japan side is real robot!! "Moe ****"* (self contradictory, blegh!) in general does not sell, only the stuff by Kyoto Animation sells consistently high.
For shounen stuff it's the stuff with large fujoshi fanbases that do well.
The actual numbers (or at least a half decent metric) for the top stuff past decade.

Theres a big change in reporting in 2007 when online started counting, so some more recent stuff will place higher.
*please just use actual critisism of the show instead of a label that makes no sense.
