Identifying these Japanese names

I’ve found an old declassified document showing Japanese vehicles (planes), but no picture is given, does anyone know which planese these are:

The armament setup is pretty wild… 6 x 20 mm cannons.

The A7M3 has 4x30mm cannons plus 2x20 mm’s.
If been searching through the internet, and apperently the A7M2 had more then one config.
So instead of the 2x20 + 2x13.7 you could have 6x20.

EDIT:

My mistake, there are multiple A7M3 variants.
