TOKYO (AP) — Those who want to climb one of the most popular trails on Japan's iconic Mount Fuji will have to book a slot and pay a fee as crowds, littering and climbers who try to rush too fast to the summit cause safety and conservation concerns at the picturesque stratovolcano.

The new rules for the climbing season, starting July 1 to Sept. 10, apply for side of the 3,776 meter- (nearly 12,300 feet-) high mountain that was designated a UNESCO World Cultural Heritage site in 2013.
