Japanese learned naval construction from the Brits. The most significant flaw in their carrier design was that the aviation gasoline piping systems and tanks could not be not well purged and lacked nitrogen blankets like American carrier had.
Shattered Sword is a great book and made me realize even more how lucky the US was at Midway.

I don’t think that USN purged the carrier fueling lines until AFTER losing Lexington in the Coral Sea.
