I did not know all the Japanese even spoke French!

Interestingly enough some authorities have said that the Japanese radial engines were based on French designs and the Soviet in-line engines were based on French designs. With vastly superior American radials and British/American in-lines you have to wonder why that would be. Was availability of French engines better internationally?

I'd be interested to learn what sources make this claim, plus their evidence for it. I can't see any common dimensions between contemporaneous French engines and the Sakai engine.

I don't know from nothing, but the French Gnome engines were used in several German aircraft such as the HS 129. That being said after the French capitulation it may be some of the Axis cross pollination going on. Again I repeat, I don't know nothing from nothing!

If you look at the Sakai's big brother, the Ha-5 or Ha-41 or Ha-109, you might see the same bore as a 14N but a slightly shorter stroke. However, they may both be parallel developments from the Bristol Jupiter.
