Pacific Historian
The IJN submarine doctrine was to use the submarine fleets to support the main fleet. It never occured to them to attack allied cargo, transports and oilers.
The IJN HQ was also a dismal failure in the operations and control of the sub fleet. Micro managing them and sending them on predictable courses and having them waste time hauling supplies. After the sinking of the USS Wasp in 1942, there was hardly one victory worth mentioning. A whole fleet of submarines with nothing to show for it.
The whole IJN submarine history can be summed up in one word..."failure".
