Commonwealth manpower for the planned invasion of Japan

Were Indian troops denied a role in the planned invasion of Japan?

No; Indian and Gurkha troops were expected to contribute, though many still had missions elsewhere in Asia.

Indian formations were still committed across Burma and related theaters, so they might advance along the Asian coast rather than all enter Japan in the first wave. Gurkha mountain troops were among the forces expected to contribute, while African and other Commonwealth formations also remained available. An invasion of Japan would demand an enormous number of troops. Commonwealth participation was expected, although the choice of first-wave formations would decide which units absorbed the initial losses.
