Separately, Kyodo News service said professional climber Keita Kurakami, 38, died in a hospital after being found by police while climbing Fuji from the Yamanashi Prefecture side of the mountain.
Fuji can be climbed from both Yamanashi and Shizuoka prefectures. The climbing season kicks in for Yamanashi starting July 1.
Mount Fuji, made famous in ukiyoe, or woodblock prints, of 18th and 19th century Edo era masters Katsushika Hokusai and Utagawa Hiroshige, is a popular tourist destination.
Experts warn it can get extremely cold, even in the summer, and proper gear, climbing boots and clothing are crucial. Trekkers are also at risk of altitude sickness if they ascend too quickly.
The picturesque Fuji has long been an iconic symbol of Japan, with its gracefully sweeping slopes and white icy cap that stand out amid tranquil lakes and rice fields.
As many as 300,000 people climb Fuji every year, and watching the sunrise from the mountaintop is coveted as a spiritual experience. But worries have been growing lately about overcrowding from the influx of tourists.
The town of Fujikawaguchiko in Yamanashi erected a large black screen along a sidewalk to block the view of Mount Fuji to discourage photo-snapping crowds.
