The discussion cautions against treating every Axis torpedo-boat comparison as a question of direct German imitation. Japanese designers examined the Schnellboot but lacked time to establish the industrial capacity needed to build it, so they chose other options. Awareness of a foreign design did not provide the plant, skills, and time needed to reproduce it during the war. The distinction keeps technological influence separate from the ability to manufacture a design at scale.

Japanese torpedo boats and the Schnellboot comparison
Japanese interest in the German Schnellboot did not translate into the industrial capacity needed to build the same type of craft.
