What Japan's Eight-Eight fleet plan actually sought

The familiar label concealed an evolving program whose final shape emphasized fast capital ships and whose treaty cancellation deepened Japanese strategic insecurity.

Question

What was Japan's Eight-Eight fleet plan, and could the country afford it?

Short answer

It was an evolving plan centered on a coherent fast-capital-ship force that Japan could more plausibly sustain than an open-ended race, though treaty cancellation intensified strategic insecurity.

Notes

The Eight-Eight idea passed through several formulations rather than representing one immutable list. The version discussed combines four older pre-dreadnoughts, eight fast battleships, and four battlecruisers after earlier plans evolved. As a coherent program it was closer to Japan's ability to finance and operate than an unlimited race with the United States. Washington's denial of the desired fast-battleship force nevertheless reinforced fears that Japan would be strategically contained and could never catch up later.
