What do you mean charts?
Basically, you need to pull stuff from islands that it "spawns" on (is created on, is created by, whatever you want to call it) and haul it to Japan. While Tracker isn't necessary for this, it would be very helpful. You can sort by which regions (and/or which bases) have the stockpiles of resources that you need to pull.
I have not really been able to get Resources, and not all Fuel/Oil, to flow through Asia from Singapore or other ports. Some seems to do so, but not all that much. Singapore, being the largest port by far in the area, will naturally pull in a lot of Resources/Oil/Fuel. Presumably, you will be dumping Fuel/Oil from Sumatra there as well. Maybe even Java or Balikpapan.
In any case, you should familiarize yourself with the loading limits at each port, which is dependent upon the port size and the Resources or Oil numbers at a base (these help with loading rates above and beyond what the port facilities do). Then find yourself some ships that will load up in a day, or an even 2 days, and have at it.
Of course, you can also always just send ships to where there's stuff to be picked up.
In game, you can find these bases (if you don't want to browse around the map) by pushing 'J' and then sorting by how much Fuel/Oil/Resources they have. The big places you'll see accumulate "stuff" would be: Balikpapan, Soerabaja, Palembang, Miri/Brunei, Singapore, and various places in the Philippines. There are some other, smaller sources that are worth grabbing if you've got ships going that way anyway.
