Mount Fuji, a UNESCO World Heritage site and an icon of Japan, has put new regulations in place for climbers amid concerns about overcrowding.

From CNN Travel, beginning July 1, climbers must pay 2,000 yen ($12.40) per person, with a daily maximum of 4,000 climbers per day.

“By strongly promoting comprehensive safety measures for climbing Mount Fuji, we will ensure that Mount Fuji, a treasure of the world, is passed on to future generations,” said Koutaro Nagasaki, governor of Yamanashi Prefecture, when announcing the new regulations earlier this year.

“In order to revive traditional mountain climbing from the foot of Mount Fuji, we will gain a detailed understanding of the Fuji-ko and Oshi culture that supported Mount Fuji worship. We look to link these cultures to this mountain climbing, as it is rooted in the cultural values of the religion.”
