The Zuihos were completed in 1940 and 1942 as conversions from Tsurigisaki (Shoho) and Takasaki (Zuiho), which had originally been constructed as 9500-ton submarine tenders as part of the Japanese "shadow program". These submarine tenders were designed for rapid conversion to either light carriers or oilers as needed. Takasaki was never completed as a submarine tender, being reconstructed while still on the ways as a light carrier.

The Zuihos were undistinguished ships, with small air groups, only modest speed, and no island. Willmott (1983) assessed them as the worst of the converted carriers. The ships retained their 350' seaplane hangars, but replaced their original diesel machinery with destroyer machinery. The flight decks narrowed considerably at their forward ends, giving them a distinctive pointed shape.
