A sightseeing helicopter carrying three people has gone missing near Mount Aso, one of Japan's most active volcanoes.
The aircraft took off from a zoo in Aso City at 10:52 local time (01:52 GMT) on Tuesday for a 10-minute tour but never returned, local reports say, quoting police.
An object resembling an aircraft was spotted by a police helicopter inside the crater of Nakadake, one of Mount Aso's five peaks, at around 16:00. Authorities have yet to confirm if it is the missing helicopter.
The helicopter's 64-year-old pilot was a veteran with 40 years of experience, according to local media. His passengers were a man and a woman, both Taiwanese.
