Informe de Operación de Rescate en el Monte Huascarán, Perú

Update 2025/6/27 22:10　 Peru time (UTC-5).

In the Cordillera Blanca of Peru, on Mount Huascarán (6,768 m), our organization’s medical advisor, Ms. Chiaki Inada (40), and her climbing partner, Ms. Saki Terada (35), have gone missing.

Currently, rescue operations are underway with the cooperation of local authorities and other relevant parties.

We sincerely apologize for the concern and trouble caused to so many people. Below is a record of the response so far.

• Ms. Chiaki Inada became incapacitated due to suspected hypothermia. An SOS was sent via the Garmin satellite communication system, notifying a local private rescue agency in Peru. (The actual distress incident appears to have occurred about 4 hours earlier, around 21:30 on June 23 local time.)
• The private rescue agency contacted WMAJ, and a fact-checking process began.

• Online meeting with Japanese and Peruvian stakeholders
  
• • Confirmation that Inada and Terada were alive
  • Text communication with Japan was possible until around 00:00 (Japan time); the climbers were waiting at the distress site, unable to move.
  • Confirmation of rescue arrangements
  • Note: The distress site is near 6,600 m, just below the summit. No helicopters in Peru can fly to that altitude, so the rescue team would fly by helicopter to the Huascarán refuge and then approach on foot. The plan was to lower them to the refuge overland and then evacuate by helicopter.
  • Coordination with local police secured through the Embassy of Japan in Peru
