GENEVA (Kyodo) A 61-year-old Japanese man has gone missing while climbing in the Alps in southern Switzerland, the Japanese Embassy in Switzerland said Friday.

He left his hotel last Sunday to climb the Jungfrau, one of the mountain range's main summits, but the hotel on Wednesday asked police to search for him and the police are looking for him by helicopter, embassy officials said.

Covered by 50-60 cm of snow even in summer, the Jungfrau can be treacherous for climbers, the officials said.
