The Imperial Japanese Navy (IJN) planned to attack the United States in 1945, but it was too late for Japan to carry out the plan. Admiral Isoroku Yamamoto, the genius behind Japan's attack on Pearl Harbor, proposed the Sensuika or I-400 Series, which would be the largest submarines ever seen. The I-400s were designed to carry attack bombers to their targets, with each submarine carrying three Aichi M6A Seiran "Mountain Haze" planes. However, delays plagued the project, with only three of the eighteen planned submarines completed by the end of the war. The Sen Toku were 60% bigger than any submarine America would construct until the nuclear submarine era. The I-400s were equipped with retractable snorkels, a sea-roving range of 37,500 miles, and a walk-in freezer for onboard meals. The I-400s were armed with eight forward torpedo tubes, a single 25mm single barrel gun, three 25mm triple barrel guns, and a larger 140mm cannon.

In 1945, Japan planned to attack American citizens using the I-400 aircraft, known as Operation PX, based on the achievements of Special Unit 731. The plan involved four Sub Division One subs sailing for the U.S. West Coast, using ceramic canister bombs filled with flea-bearing rats to unleash their ten Seirans. The final objective was the Gatun Locks in the Panama Canal. The 631st Kokutai, a new Japanese Navy Air Wing, trained pilots to attack the canal, but faced numerous challenges. On March 26, 1945, Japanese Army Chief of Staff General Yoshijiro Umez abandoned Ozawa's proposal, citing the threat of American military power. However, Japan's war chieftains supported the Panama Canal project, believing that conventional aerial bombardment would destroy the vital canal, making it the sole reason for their existence.

The battle for Okinawa began on April 1, 1945, as Japan appeared to be attacked. Sub Division One, led by Captain Tatsunoke Ariizumi, attempted to avoid Pearl Harbor by traveling the northern east-west Pacific corridor. However, the American victory on June 21, 1945, ended the 82-day Okinawa campaign. Both sides turned their attention to the Ulithi Atoll, part of the Caroline Islands, which became the final assault on Japan. The American Navy took control of the area on September 20, 1944, and all training was directed at hitting Ulithi. The I-13 and I-14 switched to the less potent Nakajima C6N1 Saiun "Myrt" long-range observation planes, while six Seirans conducted the attack. The I-13 left Ominato for Truk Island, where the destroyer escort sunken the I-13.

On July 28-29, the I-400, I-401, and I-14 advanced to attack the U.S. base at Ulithi, but were unable to communicate due to a two-day typhoon. Captain Ariizumi decided to attack Ulithi on August 25, but the I-401 veered off course. On August 14, Emperor Hirohito issued a royal decree requiring Japanese troops to cease hostilities and submit to Allied authorities. Orders were issued for the three remaining Sen Toku submarines to set the fastest courses possible to their home ports. The commanders and staff of Sub Division One had a major problem with their orders, and they didn't trust them. The next day, Navy pilot Lieutenant Robert Mahoney became the first American to see a Sen Toku sub. The American submarines boarded and spotted the I-400, leading to the American Navy studying the engineering of the I-400 series. The future of the I-400 series submarines is still up in the air if Hiroshima and Nagasaki don't step in.
