The Japanese army in 1920 imported French fighters, instructors, and
designers, and therefore fought the Pacific War with reverse
throttles. The navy meanwhile had done the same with British fighters,
instructors, and designers, hence used the throttle in the
Anglo-American fashion.

That perfectly sums up the attitude of the Japanese Navy and Army.
They seemed to regard it as a point of honour to do things
differently. Just look at their aircraft armament; they had between
them three different MG cartridges, three different HMG, five
different 20mm and three 30mm - and the only cartridge common to both
was the 7.92x57 for the German MG 15 which they both used!
