How does US/UK scoring work for the invasion of Japan?
According to Q&amp;A:

How many points does a player receive for Japan surrender if they have more than one front in that Axis country?
Per rule 9.4.G each player receives 8 VP per Axis Country (NOT front) where they have a Front. So, if the US Central and SW Pacific Fronts enter Japan during the same conference the US and the UK receive 8 VPs each , NOT 16. If in addition to this example the CBI Front also entered Japan, the same outcome would pertain. Additionally, since you only receive VPs for the last space that a front occupies this can lower a player’s potential score in some instances and is a known and intended result.
