MAEBASHI--A Gunma prefectural helicopter with nine people on board crashed around Mount Kusatsu-Shiranesan in the prefecture on Aug. 10.

Eight of those aboard the Haruna, which is used for disaster response, were found around the aircraft. Two of them were later confirmed dead, according to the Gunma prefectural government.

An Asahi Shimbun helicopter spotted a crashed Haruna around 2:25 p.m.

According to the Gunma prefectural government and other sources, the Haruna took off from Gunma Heliport in Maebashi at 9:15 a.m. with four people on board.

The four were members of the prefectural government’s air squadron to respond to disasters.

Twenty minutes later, five members of the Agatsuma wide-area firefighting headquarters boarded the helicopter at Nishi-Agatsuma Welfare Hospital in Naganohara, also in the prefecture.

The helicopter then took off again and flew toward a mountainous area spanning Gunma, Niigata and Nagano prefectures.

In the area, the nine aboard planned an aerial inspection of a mountain-climbing course that is scheduled to open on Aug. 11.

The helicopter was scheduled to return to Gunma Heliport at 10:45 a.m. However, it went missing around 10 a.m.

According to the Gunma prefectural website, the helicopter, which is 17.1 meters long, including a rotor, can accommodate 15 people.
