Tactical & Camp Notes

The traverse between Okuhotakadake and the Gendarme involves extreme vertical exposure; a climbing helmet and proven scrambling ability are mandatory.

Identified Objective Hazards

  • •Severe vertical fall risk along exposed arête sections and around the Gendarme
  • •Loose rockfall triggered by preceding climbing parties
  • •Sudden dense fog creating disorientation along narrow knife-edge ridges
  • •Freezing gale-force winds buffeting the unprotected ridgelines
