Armament

The Hashima-class cable layers (初島型電纜敷設艇,, Hashima-gata Denran-Fusetsutei) were the only class of purpose-built cable layers of the Imperial Japanese Navy (IJN), serving during World War II. Four vessels were built in 1939–41 under the Maru 4 Programme.

Apart from laying communications cables, these ships were also designed as mine planters, for the installation of controlled mines in coastal fortifications.
