Project history

Ordered under the 1921 Programme, these ships represented increased Momi and became last 2nd class destroyers. A little big sizes at invariable machinery power have led to decrease in max speed on 0.5kts. Destroyers had minelaying and minesweeping equipment. It was planed to build 13 ships, but order on last five cancelled in 1922. 14-go Kijiko, 22-go Nadeshiko, 24-go Botan and 26-go Basho were cancelled before they were laid down.
