All Chinese TT’s being worth zero would help as well. Does not effect their production and makes it more of a money pit for Japan.
This might be a good change, but I would deffinitely leave Manchuria, Kiangsu, Kwangtung, and French Indo-China’s IPC values alone.
The coastal areas were quite important and definitely worth the IPCs. I live in Manchuria, and the Japanese really took a lot of economic resources out of this area and built up this area a lot. A Japanese starting IC in Manchuria would not be out of line historically.
Maybe 1 or 2 of the other territories could still be worth 1 IPC, but having 3-5 of the interior starting Chinese territories with 0 IPC values definitely might be a good change.
