Rescue operations are underway in southwestern Japan’s Kumamoto Prefecture after a sightseeing helicopter carrying three individuals vanished during a tour near the volatile Mount Aso volcano. The aircraft, operated by Takumi Enterprise, departed from Aso City Zoo at 10:52 local time Tuesday for what should have been a routine 10-minute scenic flight but failed to return as scheduled.
According to local authorities, police helicopters scanning the area later identified an object resembling an aircraft within the crater of Nakadake—one of Mount Aso’s five distinct peaks—during afternoon surveillance. Official confirmation regarding whether this object is indeed the missing Robinson R44 helicopter remains pending as investigation continues.
The flight manifest included a 64-year-old veteran pilot with four decades of aviation experience and two Taiwanese tourists. The operator confirmed the aircraft had completed two uneventful tours earlier that day before disappearing on its third scheduled trip. Weather conditions at the time of disappearance were reported as cloudy over the Nakadake region, complicating initial search efforts which were suspended Tuesday evening due to visibility constraints before resuming at dawn Wednesday.
In response to the incident, Takumi Enterprise has temporarily grounded its entire fleet of sightseeing helicopters. The volcanic helicopter tours represent a significant tourism attraction for the region, offering aerial views of one of Japan’s most geologically active landscapes. This incident echoes a previous emergency involving the same company in 2024 when one of their helicopters made an emergency landing at Mount Aso, resulting in injuries to three occupants.
Mount Aso, which last erupted in October 2021 producing substantial volcanic plumes, remains one of the country’s most monitored volcanic zones due to its persistent activity.
