Reddit mentions of Kaigun: Strategy, Tactics, and Technology in the Imperial Japanese Navy, 1887-1941

If you're interested in the IJN, then Evan's and Peter's Kaigun is the essential book:

This is right in my wheelhouse! My own expertise on the war in the Pacific is mainly naval, but yes, I know some good books about that!

I would recommend, first of all, Clayton James' essay American and Japanese Strategies in the Pacific War, located in Peter Paret's Makers of Modern Strategy, which provides exactly what you are looking for. After that, I recommend George Baer's One Hundred Years of Sea Power: The U.S. Navy, 1890 - 1990 (the relevent sections, obviously; not the whole thing) and Doug Smith's Carrier Battles: Command Decision in Harm's Way for a good overview of the US Navy's role in the development of American strategy, policy, and operations against Japan, as well as how interwar Navy PME influenced their thinking on these issues.

David Evans and Mark Peattie's Kaigun: Strategy, Tactics, and Technology in the Imperial Japanese Navy, 1887 - 1941 is absolutely imperative for any kind of understanding of the Imperial Japanese Navy's strategic, institutional, and doctrinal shortcomings as they were eventually revealed during WWII. And I highly recommend Ron Spector's Eagle Against the Sun: The American War with Japan, which also offers excellent analysis on the comparative merits and shortcomings of Japanese and US naval strategy.

Gerhard Weinberg's A World At Arms: A Global History of World War II is a bit daunting (1200 pages!) but provides the single best overall review of the war, including the war in the Pacific. For a look at US Army strategy, I'd recommend the US Army Green Book Series on the war in the Pacific; these books were written by Army staff and historians in the decade or two following the war, and offer a perspective that is sometimes difficult to find in more recent works.
