How Britain might handle a defeated Japan

How might Britain have treated Japan after winning a Pacific war without the United States?

The expected outcome is surrender under blockade pressure followed by naval-construction restrictions, without a prolonged British occupation.

The counterfactual distinguishes a British war against Japan from the eventual American-led settlement. Britain did take part briefly in the actual occupation, but the proposed British-only outcome centres on forcing surrender through blockade and starvation. The scenario anticipates negotiations if Japan yields, while acknowledging the severe civilian consequences of continued resistance. The resulting restrictions would focus on Japan's navy and its ability to resume naval construction. Germany's postwar naval limitations provide the comparison for that proposed settlement.
