19 February 1945: American Operation "Detachment" - The Invasion of Iwo-Jima:
Vice Admiral (later Admiral) Raymond A. Spruance's Fifth Fleet of over 450 ships, lands the 54th Amphibious Corps (3rd, 4th, 5th Marine Divisions) who later capture the island and its vital Motoyama airfields from LtGen Kuribayashi Tadamichi's defenders.
20 February 1945: The Third Kaiten Mission:
The order to form the next Kaiten group operating in the open sea is issued by Headquarters, 6th Fleet. The American landing on Iwo happened earlier than expected, so the training is cut short.
I-368 is in the "Chihaya" group with I-44 and I-370. The mission calls for the group to launch their kaiten at anchored American shipping off Iwo Jima. I-368 departs Hikari on her first sortie (the very first kaiten carrier to do so) with pilots Lt.( j.g.) Kawasaki Junji, Ensigns Ishida Toshio and Namba Susumi, FPO2C Isobe Takeo and Shibazaki Shoshichi aboard.

I-368 is not moving and Fay overshoots her on his first pass. He drops a float light marker, sonobuoys and then releases a Mark 24 "Fido" acoustic homing torpedo. At 0338, I-368's conning tower breaks the surface near the marker, but LtCdr Irizawa quickly dives. Another Avenger arrives and drops more sonobuoys and another Fido. The attacks sink I-368 at 24-43N, 140-37E with her crew of 86.
