Police dug up two male bodies Monday from a campsite in a mountainous area of Tsuru, Yamanashi Prefecture, officials said.
The officials of the Tsuru police station said the corpses found in the Asahigawa camping ground have not yet been identified. Although local police received anonymous tips several months ago that human remains were buried at the campsite, they did not begin searching the area until Monday morning.
The police said the campsite, managed by local construction firm Asahi Kensetsu, is currently closed.
Investigators will question Asahi Kensetsu President Yoshihiro Asa, 54, about the bodies, the officials said.
Asa and two former employees of the firm were arrested in September for allegedly embezzling about 1 million yen in benefits from an insurance contract they took out on a former employee of the company.
Both of the bodies have decomposed, police said. One of them was dressed and appears to be that of an adult.
According to members of the local construction industry, Asahi Kensetsu was established several years ago by people from outside Yamanashi Prefecture. The company reportedly also recruited day laborers and acted as a dispatch agent.
"People rarely visit the area" after the summer camping season ends, a worker from a nearby temple said, "and at nights I see only a few vehicles a month."
