A practical Japanese alternative to Yamato

What should Japan build instead of the Yamato class?

More ships, centered on a fast long-range battleship with triple 16-inch guns and efficient use of Japanese infrastructure.

If Japan still built Yamato, secrecy would squander much of the capital ship's status value. A prestige ship can shape foreign perceptions only when other powers know it exists. Without Yamato, the preferred alternative is a larger number of useful units centered on a fast, long-ranged battleship with triple 16-inch guns. Nelson and Dunkerque provide models for concentrating firepower efficiently within Japan's infrastructure.
