How new capital ships reshape Japanese cruisers and destroyers

How would continued capital-ship construction affect Japanese cruiser and destroyer development?

Japan might build fewer top-heavy cruisers and destroyers because the new capital ships would already provide strength that smaller types historically had to offset.

The historical fleet tried to compensate for numerical inferiority by loading exceptional capability onto smaller hulls. Four new battleships would reduce the need for every cruiser and destroyer to serve as an asymmetric answer to the American battle line. Japan could therefore place less pressure on individual designs to carry an extreme share of the fleet plan. The answer remains conditional because the final cruiser and destroyer programmes would also depend on treaty limits and available yard capacity.
