The I-36 is transferred E of Hawaii to avoid detection, but numerous contacts are still made.

16 October 1943:
After sunset, the I-36 surfaces 120 nms S of Pearl Harbor. Her E14Y1 floatplane is assembled in ten minutes and launched from the catapult.

One hour and twenty minutes later Cdr Inaba receives the signal from the returning floatplane. The partially submerged I-36 heads for the rendezvous point while maintaining contact with the pilot on a long-wave channel. The fliers report sighting four carriers, four battleships, five cruisers and 17 destroyers at anchor.

By 2330, the pilot of the Glen reports that his plane is low on fuel and that he has lost the bearing to the submarine. The I-36 surfaces and heads towards the location of the aircraft at full speed, with navigation lights switched on. Contact with the Glen is lost.

19 October 1943:
300 nms S of Hawaii. En route to Kwajalein, Cdr Inaba sights a convoy of six fleet oilers heading SW at 10 knots. He starts an approach but is forced under by the escorting destroyers.

Departs Kure carrying an E14Y1 Glen floatplane to harass the American supply lines E of the Marshall Islands and to reconnoiter the Majuro anchorage. Although the I-16, -32, -38 and the I-45 are assigned the same task, only the I-36 and the I-16 participate.

16 April 1944:
In the afternoon, the I-36 detects screw noises. LtCdr Teramoto sights an enemy carrier turning into the wind to recover her aircraft. During her apporoach the I-36 is spotted by a destroyer. About 1400, from 2,190 yards, Teramoto fires six torpedoes at the carrier before diving to 100 feet. Two minutes and 10 seconds later two explosions are heard. Six hours later the I-36 surfaces but no enemy vessels are in sight.

22 April 1944 - "Operation Persecution":
Rear Admiral (later Vice Admiral) Daniel E. Barbey's Task Force 77 lands the 41st Infantry Division of the I Army Corps at Humboldt Bay, Hollandia, New Guinea. Rear Admiral Ralph E. Davison TF 78 escort carrier provides close air support while British Rear Admiral (later Admiral Sir) Victor A. C. Crutchley's TF 74 and Rear Admiral (later Vice Admiral) Russell S. Berkey's TF 75 provide gunfire support. Vice Admiral (later Admiral) Marc A. Mitscher's fast carrier Task Force 58 also provides support.

Majuro. At 1455 (JST), the I-36 launches her Glen floatplane that flies over the anchorage at 3,900 feet. The observer reports sighting 11 carriers and three battleships. Upon return, the pilot of the E14Y1 fails to locate the submarine. Contact is re-established only by dawn the next morning. The aircraft is scuttled, rather than recovered, to escape detection.

23 April 1944:
LtCdr Teramoto reports the results of the mission. In response to the landings at Hollandia, HQ, Sixth Fleet orders another flight to check the presence of enemy carriers at Majuro (conducted on 12 June by a floatplane from the I-10).

30 April 1944:
At 2025 (JST), the surfaced I-36 is attacked by a patrol plane, but manages to crash-dive to 260 feet. Other aircraft arrive and drop a total of 36 depth-charges, but the damage inflicted on the I-36 is minor.

9 May 1944:
Returns to Kure. The CINC, Sixth Fleet issues an All Naval Units Proclamation to Teramoto for the sinking of an enemy carrier.

May 1944:Operation "Tatsumaki" (Tornado) - Amphibious Tank Attack at Majuro, Marshall Islands:
Inland Sea. The I-36 participates in training with the I-38, -41, -44 and the I-53. The operation calls for the submarines to carry amphibious tanks armed with torpedoes from Kure to Majuro. There they are to be put ashore, make their way overland, enter the water again and make a torpedo attack on American ships. Later, the plan is cancelled.

23 May 1944:
The I-36 carries out diving tests in the Aki Nada with two Type 4 amphibious tracked "Ka-Tsu" vehicles embarked.

19 June 1944:
Departs Kure on a supply mission to Truk.

13 October 1944: Operation "Sho-1-Go" - The Defense of the Philippines:
Admiral Toyoda Soemu (former CO of HYUGA), CINC, Combined Fleet, orders the Sho-1-Go plan activated.

7 November 1944:
Otsujima Kaiten Base, Tokuyama Bay. Vice Admiral Miwa advises crewmen of the plans for a kaiten attack on the American Third Fleet's anchorage at Ulithi Atoll.

8 November 1944: The First Kaiten Mission:
The I-36, -37 and the I-47, each with four kaiten and eight conventional torpedoes embarked, form the "Kikusui" (Floating Chrysanthemum) Group. They depart Otsujima at 0900 under the command of ComSubDiv 15, Captain Ageta Kiyoi aboard the I-36. The I-36 and I-47 are ordered to attack Ulithi. The I-37 has to attack enemy shipping at Palau.

After negotiating Bungo Suido, the leading I-36 sends the signal to the other submarines to proceed independently.

16 November 1944:
A Nakajima C6N1 Saiun ("Myrt") long range high-attitude reconnaissance aircraft from Truk reports that four fleet carriers, three battleships, cruisers and destroyers are in the north central part of the Ulithi lagoon while south central part of the anchorage is occupied by transports, oilers and other vessels. This intelligence is relayed to the Kikusui Group's submarines.

Just before dawn, Lt (j.g.) Richard L. Simms' PBM Martin "Mariner" seaplane of VPB-21 was finishing her night patrol and returning to Ulithi when her radar operator picks up the I-36 running on the surface. As the Mariner approaches, LtCdr Teramoto crash dives. Simms' crew drop sonobouys in her wake, but the I-36 escapes.

19 November 1944:
The I-36 and I-47 of the Kikusui Group reach their launching area off Ulithi Atoll.

20 November 1944:
LtCdr Teramoto's I-36 is submerged preparing to launch his kaiten into the Mugai Channel, the eastern opening to the Ulithi anchorage. When I-36 surfaces, Ensign Imanishi Taichi and three other pilots board their kaiten. They engines start the first two Kaiten, but the weapons are immovably wedged in their chocks. The third kaiten fails to start because of a leak in engine compartment. Only Ensign Imanishi's No. 3 gets away at 0454. The I-36 dives and listens for explosions.

Imanishi penetrates the safety nets across the mouth of the harbor undetected. At 0545, his kaiten hits the starboard side of the 11,316-ton oiler USS MISSISSINEWA (AO-59) in the center of Mugai Channel. The MISSISSINEWA, loaded with 440,000 gallons of aviation fuel, erupts into flames.

The I-36 is chased by enemy destroyers; some hundred depth-charges are dropped on her. The damage is minor.

23 November 1944:
The I-36 reports the results of her attack to the Sixth Fleet. That same day a C6N1 "Myrt" from Truk flies over the anchorage to assess the damage. Although a large oil slick is observed, the number of anchored vessels has not changed essentially.

24 November 1944:
The I-36 and the I-47 receive a signal that cancels their orders to proceed to Leyte. Instead, they are ordered to return to Kure.

30 November 1944:
The I-36 and I-47 return to Kure via Otsujima where the defective kaitens are disembarked.

2 December 1944:
A special conference of more than 200 staff officers and specialists is held aboard the Sixth Fleet's flagship, the TSUKUSHI MARU to evaluate the Kikusui mission to Ulithi. The staff considers reports and post-attack photo reconnaissance and concludes erroneously that three aircraft carriers and two battleships were sunk in the attack. Ens Imanishi is credited with the sinking of an aircraft carrier.

29 December 1944: The Second Kaiten Mission:
The I-36, -47, -48, -53, -56 and the I-58 from the "Kongo"(Steel) Group. The plan is to attack the Americans at five different points.

30 December 1944:
The I-36 departs Kure with the I-53 and the I-58.

9 January 1945:
Approaching Ulithi the I-36 runs aground on a reef, but manages to free herself, blowing her main tanks.

12 January 1945:
Ulithi Lagoon. Between 0342 and 0357, LtCdr Teramoto launches his four kaitens, piloted by Lt Kagaya Takeru, Lt (j.g.) Todokoro Shizuyo, Ensign Motoi Bunya and CPO Fukumoto Yurimitsu. A PBM of VPB-21 (again flown by Lt Simms) spots a midget submarine in the lagoon. Simms drops four depth charges and sinks a kaiten launched by the I-36.

Postwar analysis indicates that one kaiten damaged the ammunition ship USS MAZAMA (AE-9) and another sank the LCI-600 (Landing Craft Infantry).

21 January 1945:
Returns to Kure. The kaiten pilots from the I-36 are credited with the sinking of four enemy vessels.

5 February 1945:
LtCdr Teramoto is relieved by LtCdr Sugamasa Tetsuaki (former CO of RO-49).

19 February-26 March 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 capture the island and its vital Motoyama airfield from LtGen Kuribayashi Tadamichi's defenders.

28 February 1945: The Fourth Kaiten Mission:
The I-36 and the I-58 are assigned to form the "Shimbu" ("Divine Warriors") unit to attack American shipping anchored off Iwo Jima. The I-36's aircraft hangar and catapult are removed to accommodate two more kaitens on the foredeck. A Type 13 air-search radar is fitted in front of the conning tower.

2 March 1945:
Departs Hikari with four kaitens embarked, following the I-58.

6 March 1945:
The Combined Fleet directs the Sixth Fleet to cease operations in the Iwo Jima area. The I-36 is recalled.

The I-36 returns to Kure.

1 April 1945: American Operation "Iceberg" - The Invasion of Okinawa:
Vice Admiral (later Admiral) Raymond A. Spruance's Fifth Fleet, including more than 40 aircraft carriers, 18 battleships, 200 destroyers and over 1,000 support ships surround Okinawa. LtGen Simon B. Buckner Jr's Tenth Army (7th, 77 th, 96th Infantry, 1st, 6th Marine Divisions) makes amphibious landings and takes the island from LtGen Ushijima Mitsuru's 32nd Army.

22 April 1945:
Departs Hikari in the "Tembu" ("Heavenly Warriors") group to operate between the Marianas and Okinawa with six kaitens embarked.

25 April 1945:
Off Iheya Jima. At night, LtCdr Sugamasa observes a Martin PBM-3 "Mariner" on an ASW patrol.

27 April 1945:
E of Okinawa. Early in the morning, the I-36 sights an American convoy of 28 ships. LtCdr Sugamasa launches four Kaitens piloted by Lt(j.g) Yagi Teiji, PO2C Abe Hideo, Ebihara Kiyosaburo and Matsuda Mitsuo. Two of the kaitens malfunction and cannot be launched. LtCdr Sugamasa reports sinking four transports, but, in fact, all the kaitens are unsuccessful.

30 April 1945:
The I-36 returns to Kure.

1 May 1945:
Vice Admiral Daigo Tadashige relieves Vice Admiral Miwa of command of the Sixth Fleet (Submarines).

4 June 1945:
The I-36, with six kaitens aboard, departs Hikari with the "Todoroki" ("sound of great cannon") group to patrol east of Guam.

22 June 1945:
Saipan. The I-36 sights an oiler, sailing alone. LtCdr Sugamasa attempts to launch two kaitens, but both malfunction. He then attacks with four conventional torpedoes which explode prematurely, causing slight damage to the landing craft repair ship USS ENDYMION. Sugamasa reports seeing the ENDYMION assume a slight list, but then manages to pick up speed and escape thereafter.

28 June 1945:
400 nm NNE of Truk The stores issue ship ANTARES (AKS-3) is sailing alone from Saipan bound for Pearl Harbor. The I-36 spots and attacks the ANTARES at 13-10N, 154-57E. LtCdr Sugamasa launches a kaiten piloted by Lt(j.g.) Ikebuchi Nobuo.

At 1329, ANTARES' lookouts report a periscope and wake 100 yards on her starboard quarter. The ANTARES goes hard right and the torpedo misses astern. Then the lookouts see a kaiten in the port wake, turning to the right. At 1331, the ship opens fire at the kaiten's periscope wake and zigzags to avoid. While the ANTARES' stern swings to starboard, one of her 3-inch guns scores a hit on the kaiten and it disappears. At 1344, another periscope appears. The I-36 broaches and the ANTARES' aft 5-inch gun opens fire at her.

The USS SPROSTON (DD-577), steaming to the States for overhaul, is signaled by the ANTARES that she is under attack. Arriving in the vicinity, the destroyer makes sonar contact at 1,000 yards. At 500 yards a periscope is observed passing from starboard to port. The destroyer makes an unsuccessful attempt to ram the submarine. Then she drops a full pattern of depth charges. A large oil slick is later observed. She makes six more attacks with negative results.

One of the SPROSTON's lookouts spots a torpedo wake approaching 60 degrees off her port bow. The destroyer turns hard left and the torpedo passes along her port side. A kaiten's periscope is sighted off the port quarter. The SPROSTON's main battery commences firing and a salvo hits the kaiten, causing a large secondary explosion. Other ships arrive to help conduct night radar coverage of the area. After more than ten depth-charge explosions, the I-36 receives a leak in the forward torpedo room. In order to escape, LtCdr Sugamasa launches two more kaitens from a depth of 200 feet to engage the destroyer, piloted by Ens Kuge Minoru and FPO1C Yanagiya Hidemasa.

The next morning, three destroyer escorts join the group. After a thorough search, all ships depart the area. The I-36's rudder is damaged in the attacks, but she slips away.

29 June 1945:
LtCdr Sugamasa is running on the surface when the I-36 is bombed and a fuel tank ruptured by an American patrol plane.

5 July 1945:
Bungo Straits. The I-36 is running on the surface when she is attacked by LtCdr Guy E. O'Neil's USS GUNNEL (SS-253), but all four torpedoes miss, passing astern.

6 July 1945:
Returns to Kure.

11 August 1945:
