A stonemasonry wall at a shrine near the summit of Mt. Fuji was roped off on Tuesday, a day after a falling rock hit and killed a Russian climber.
The woman has been identified by police as Anna Dubrovina, 29, a resident of Tokyo's Shinagawa Ward.
While there have been no reports of rocks falling from the stonemasonry, the measure was taken to prevent people from climbing the wall at the shrine on Japan's tallest mountain, according to the Yamanashi prefectural government.
It remains unclear from where the rock that killed Dubrovina was dislodged.
Last fall, stonemasonry at the shrine on the 3,776-meter volcano collapsed following a typhoon and was temporarily covered by nets.
A trail between a cabin located around 3,450 meters up the mountain and the summit, which had been closed due to the accident, reopened Tuesday morning.
