  1.  @erichammond9308  the IJN did use the Vickers pompom in the 1920s and early 30s. The guns were built in Japan under license. The pompom was replaced by the 25mm.

  2.  @erichammond9308  the pompom's shortfall is short range. The 25mm has a significant advantage in range. Navweaps gives a max ceiling, for the high velocity version of the pompom MV 2300fps, which Japan did not have, of 13,300ft, vs 18,000 for the Type 96. If the Japanese had licensed the Italian 37mm, they would have a more formidable AA defense as it threw a larger shell than the Type 96, with a higher ceiling, 16,400ft, than the pompom, with a loading system that eliminated the reload stoppages of the Type 96. And the Italian twin 37mm, was available from 1932.
