Pandey said attempts are being made to bring down the body of the 59-year-old climber, and it most likely will be picked up on Saturday by a helicopter from a lower camp.
Takashi was attempting to reach the 29,035-foot (8,850-meter) summit with a team of international climbers.
He is the third climber to die this year while attempting to climb the world's highest peak from the southern side. More than 200 climbers are known to have died while attempting to climb Everest.
