STEVENSON, Wash. (AP) — The Skamania County sheriff's office says human remains found earlier this month on Mount St. Helens have been identified as those of a 27-year-old Japanese hiker reported missing last November after indicating he planned to climb the southwest Washington volcano.

Undersheriff Dave Cox said Monday that the Clark County medical examiner's office identified the remains found Aug. 9 as those of Yosuke Onishi. The remains were found near the 7,100-foot level on the south slope of the mountain. The crater rim stands at 8,365 feet.

No cause of death has yet been determined. Cox says once the Skamania County coroner receives the medical examiner's reports, it is possible the coroner can make that determination.

Onishi was reported missing last Nov. 27 after failing to return to the Lone Fir Resort in Cougar, Washington, to pick up his personal effects. Cox says Onishi reportedly left the resort that morning with a plan to summit the volcano.

Onishi was from Saga Prefecture on the island of Kyushu.
