On the Japan 1 move…
First off, add a bid of 5-9 for the Axis to even the odds.
Then build 1 IC, 2 TRN as Japan on J1. That gets you SEVEN units to Asia on J2, 9 if the SZ59 TRN miraculously survives…
Also, if you can take India, FIC is a better place for your first IC, if not then MANCHURIA, not KWANG.
