The No.7 class minesweeper (第七号型掃海艇,) was a class of minesweepers of the Imperial Japanese Navy (IJN), serving during the Second Sino-Japanese War and World War II. 6 vessels were built in 1937-39 under the Maru 3 Keikaku.

Background

 * Project number I4. Improved model of the No.13-class. They were built to update timeworn No.7-class, No.9-class and No.11-class. Kampon deleted minelayer facility from them, because IJN hoped they act in Yangtze River. And they added to 1 × 120 mm naval gun for engage with National Revolutionary Army. Therefore, No.7-class had the silhouette which resembled torpedo boat Chidori-class and Ōtori-class well.
