Were Japanese supply destroyers stripped of weapons?

Had the Japanese destroyers removed torpedoes or guns to increase cargo capacity?

The evidence is inconclusive; they may have carried reduced armament or fewer reloads, but they probably retained at least part of their combat capability.

Available accounts do not settle the exact configuration of these ships. They may have carried reduced armament or fewer torpedoes and reloads, but they were unlikely to have been stripped of every weapon while operating through contested waters. The launchers probably remained aboard while some torpedoes or reloads were landed, and weak forward support may also have delayed upgrades. These remain probabilities rather than a confirmed loadout.
