There are lots of resources in the "Southern Area" (outside Japan), and a number of Japanese cities which need resources. Kyoto, for example, has low levels and no port.
Playing Jap campaign game, Do I need to move resources from, say, Palembang to Japan, or will the auto convoy system take care of it? Do I need to put the base on the convoy system? (I'd rather not - some places don't need a large shipment of supplies.)
How do I move resources from a port or city with lots of resources to cities that need resources, like Kyoto, Matsue, Masan, Kanazawa, etc.?
