Former submarine tenders, which design provided fast conversion to aircraft carriers. Tsurugisaki and Takasaki (9500/13000t, 2 diesels, 56000hp, 29kts, 2x2 - 127mm/40, 12 light guns, 3 seaplanes) were built under 2nd Supplementary Programme of 1934. Tsurugisaki was commissioned 15.1.1939, and already launched Takasaki approximately during the same time have started to rebuild to carrier; she was completed in new quality under name Zuiho. In November, 1940 on Yokosuka N Yd conversion Tsurugisaki, renamed to Shoho, has begun.
Reconstruction of the ships was more thorough, than it provided by pre-war plans. Unsuccessful diesel machinery it was necessary to replace by turbines, unified with Kagero class destroyers. As a whole arrangement and architecture of carriers reminded Ryujo: actually, on the basis of the latter hulls of tenders were designed. Interesting feature of carriers was very long and narrow hull (L/B rate was 11.1), equipped, nevertheless, by underwater protection of cruiser type. Armour was absent, but as local protection of magazines and petrol tanks original box capacities with double sides were used, space between this double sides was filled with water. One more unusual detail of architecture of the ship was an additional funnel smoke tube aft, intended for exhaust gases of diesels-generators.
There was cruiser-type underwater protection.
1943, Zuiho: flight deck was lengthened to 192.6 m; - 4 x 2 - 25/60; + 16 x 3 - 25/60 96-shiki, 1-shiki 2-go radar
1944, Zuiho: + 20 x 1 - 25/60 96-shiki, 6 x 28 - 120 AA RL
