On January 20, 2026, a Robinson R44 Raven II helicopter on a sightseeing tour crashed inside Mount Aso. All three onboard, including two Taiwanese tourists and the pilot, remain missing. [1] [2] [3] [4] This is the second incident of an aircraft crashing inside a volcanic crater, following the helicopter crash at Mount Kilauea volcano in November 1992. [5] [6]
The aircraft JA10KE, a Robinson R44 Raven II helicopter owned and operated by Takumi Enterprise (匠航空株式会社), was conducting local sightseeing flights of the Mount Aso area for the Cuddly Dominion (阿蘇カドリー・ドミニオン), the zoo in Kyushu, Japan.
There were three people aboard the helicopter: two passengers and one pilot. The two passengers were a married couple from Taiwan, identified as a 41 year-old male and 36 year-old female. The pilot was identified as a 64 year-old male, who had 36 years of flight experience. [7] [8] [9] [10]
The helicopter was operated by Takumi Enterprises (匠航空株式会社), founded in 2001. The company's main business includes sightseeing flights and humanitarian rescue operations such as supporting disaster-stricken areas, rescue missions, and medical transportation.
The company has also faced scrutiny regarding its safety. Prior to this accident, there had been five other incidents, including a tail-strike, a fuel emergency, and a technical malfunction. On May 13, 2024, a Robinson R44 Raven II helicopter, the same model as the one involved in this accident, made a crash landing due to engine failure, resulting in serious injuries to three people.

On January 20 at 10:52 a.m. JST, the helicopter took off and was en route for the local sightseeing flights of Mount Aso. The 3 occupants included 2 Taiwanese tourists and the pilot, all of whom went missing during the flight. Meanwhile, one of the tourist's iPhone began sending SOS requests automatically via Apple Emergency SOS due to the amount of G-force detected by the device at around 11:04 a.m. JST. [14]
On 20 January, the Kumamoto police force succeeded in finding the crashed helicopter in the afternoon. However, the rescue was halted due to ground freezing, volcanic gases and strong winds on Mount Aso. As of January 22, rescue operations could not begin after the accident and were postponed to January 23. [15] [16] [17]
On January 23, three days after the accident, the fire department, the Self-Defense Forces, Aso City and other relevant departments held a meeting at 10:00 a.m. JST to discuss future search methods. [18] [19] However, the meeting did not determine specific rescue methods or a timetable. A fire department official indicated that the rescue operation could take a considerable amount of time. [20]
