Two Japanese were found dead Monday in a climbing accident after going missing Sunday on a Pacific island in Russia's Far East region, officials of the Japanese Consulate General in Yuzhno-Sakhalinsk said.

The two were identified as Tomoki Sugawara, 27, and Satoshi Shimazaki, 28. They are believed to have fallen while climbing a mountain, but details of the accident are not yet known, the officials said.

Sugawara and Shimazaki were visiting Atlasov Island, part of the Kuril Islands chain in the Kamchatka region, to climb Mount Alaid.

They were accompanied by three Russians, including an interpreter. One of the three Russians was also injured.

Local authorities sent helicopters to search for the two Japanese on Monday morning and found the bodies about six hours later, the officials said, adding that their bodies were being sent to Petropavlovsk-Kamchatskiy, a city on the Kamchatka Peninsula.

The 2,339-meter Alaid is the highest active volcanic mountain in the Kuril Islands.
