Built beginning in 1923 with the assistance of German technicians, the J1s were Japan's first attempt at a cruiser submarine (Junyo sensuikan or Junsen), with great range, light armor, and large torpedo loadout. They differed from the Kadai (KD) series in that the Kadai were intended to operate with the fleet, while the Junsen were to operate independently in distant waters. They were large submarines equipped to serve as flagships for submarine squadrons. Their design was similar to the German U-142 type.
