Why Japan did not immediately reuse the name Mikasa

Why was the name Mikasa not reused by the Imperial Japanese Navy after the ship's retirement or by the postwar navy?

The interwar navy looked toward newer ships, while Mikasa's connections with imperial expansion made the name and its symbolic role politically sensitive for postwar Japan.

Mikasa's association with the Six-Six Fleet plan and the First Sino-Japanese War makes reuse of the name politically sensitive. In the interwar period, attention went to newer ships and future development. The postwar navy also avoided some historical touchstones connected with imperial expansion. Mikasa could serve as a national naval symbol comparable to HMS Victory or USS Constitution, but adopting that role would require a substantial political decision. Changing attitudes leave future reuse possible without making it certain.
