Verdict

India holds a 57–43 advantage over Japan on the Relative Advantage Index.

The margin is driven by military spending (60% of the combined total, $92.1bn) and active personnel (86% of the combined total, 1.5m). Japan leads on logistics & power projection and economic size (GDP).

1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
