Four days following Japan's surrender on September 2, 1945, the remaining forces still in Rabaul, New Britain, reached out to the Allies to indicate their intention to surrender.
Following negotiations, the only aircraft remaining in operational condition received approval for a final flight from Rabaul to Jacquinot Bay Airfield on New Britain's southern coast.
As stated by online sources:
"On September 18, 1945 the first flight included Ki-46 Dinah 2783, A6M5 Zero 4043, A6M5 Zero 4444 and A6M5 Zero 3479 escorted by sixteen Allied fighters.
On October 14, 1945 the second flight included B5N2 Kate Tail 302 and E13A Jake 4326."

kikusui marking designed by maintenance crew member Sgt Maj Azuma.
According to non-Japanese online sources, the "Dinah" pilot was Capt Iwanaga Nario but FAOW #38 mentions that his name was 2Lt Sato Teruo.

Here's the story of the aircraft of the "Last Rabaul Airforce" from a Japanese source:
"By late 1943, the only remaining IJAAF reconnaissance units in Rabaul were parts of the 10th
Sentai equipped with "Dinah" and the Dokuritsu 83 Chutai equipped with "Sonia." In March 1944, only a single 10th Sentai "Dinah" remained in Rabaul, yet three additional "Dinahs" from Wewak were dispatched to Rabaul to participate in the 17th Army's
Torokina Operation. One of the three "Dinahs" suffered damage from friendly anti-aircraft fire and performed an emergency landing, resulting in three operational "Dinahs" from the 10th
Sentai remaining in Rabaul. A while later, enemy forces destroyed one of them on the ground, while another was shot down right after taking off. Consequently, just a single "Dinah" was left operational in Rabaul.
"During that period, the IJAAF conceived the notion of collecting components and constructing several aircraft. Initially, the ground teams successfully assembled two "Dinahs."
"In a similar manner, the IJNAF succeeded in gathering five Zeros and two "Kates". Numerous tropical diseases afflicted the region, particularly malaria, prompting the "Dinahs" to take 3-4 trips to Truk to deliver medicine to Rabaul. The "Dinahs" achieved great success, and to utilize the leftover "Sonia" pilots, the remnants of the 1st and 11th Sentai chose to collect parts and successfully assembled 5-6 "Hayabusa" fighters, which were designated the "8th Area Army." Embarkments were built as well, but before their completion, all "Hayabusa" fighters and one "Dinah" were destroyed on the ground.

Four surrendered Japanese aircraft after arrival at the RNZAF airfield at Jacquinot Bay. The formation consisted of three Mitsubishi A6M5 Model 52 Zero fighters of the Imperial Japanese Navy (including serial numbers 3479 and 4043), and one Ki-46 Dinah reconnaissance aircraft (serial number 2783) of the Imperial Japanese Army. The aircraft were flown by Japanese crews, and departed Vunakunau at Rabaul with an escort of RNZAF F4U Corsair fighters. All the Japanese aircraft wear surrender markings, which consisted of an overall white finish with green crosses for easy recognition. (RNZAF Official Photograph.) (AWM)
A Nakajima B5N2 'Kate' bomber of the Imperial Japanese Navy. This aircraft, coded '302', was the last flyable bomber left at Rabaul by the end of the Second World War. The aircraft was operated by the 105th Naval Base Air Unit. Escorted by four RNZAF Vought F4U-1 Corsair fighters, on 14 October 1945 it was flown to Jacquinot Bay by Warrant Officer Kataoka Goro and surrendered. The photograph depicts Japanese ground crew probably at Rabaul preparing the aircraft for its last flight. (AWM)
This is the Japanese carrier-borne B5N2 "Kate" bomber which was also captured at Rabaul in September 1945. It too passed into RNZAF possession and was flown to Jacquinot Bay, but as no shipping space could be found to return it and two Zero's also captured to New Zealand, the three aircraft passed into RAAF ownership. They were left at Jacquinot Bay and according to 'Aircraft of the Royal New Zealand Air Force' by David Duxbury, Ross Ewing and Ross Macpherson (Heinemann, 1987) were still there as late as 1972, along with the Dinah seen below and at the top of this page.

This is the Japanese E13A1A "Jake" reconnaissance seaplane which was captured at Rabaul in September 1945. It passed into RNZAF possession and was flown to RNZAF Station Jacquinot Bay, where a month later it sank at its moorings. The remains are probably still there. Photo:
