Hikers attempting any of Mount Fuji's four main trails will be charged an entry fee of 4,000 yen ($27) from this summer, after local authorities passed a bill on Monday.
A record influx of foreign tourists to Japan has sparked alarm about overcrowding on the nation's highest mountain, a once-peaceful pilgrimage site.
Last year, Yamanashi region -- home to Mount Fuji -- introduced a 2,000 yen ($14) entry fee plus an optional donation for the active volcano's most popular hiking route, the Yoshida Trail.
A cap on daily entries and online reservations were also brought in on that trail by officials concerned about safety and environmental damage on Fuji's majestic slopes.
The Yoshida Trail fee will be doubled for this year's July-September climbing season, while neighboring Shizuoka region passed a bill on Monday to also charge 4,000 yen for its three trails, which were previously free, AFP reported.
Thanks in part to the new restrictions, the number of climbers who tackled Mount Fuji declined to 204,316 last year, from 221,322 in 2023, environment ministry data shows.
Although climber numbers continue to be eclipsed by pre-pandemic levels, "200,000 hikers is still huge", Natsuko Sodeyama, a Shizuoka prefecture official, told AFP.
"There is no other mountain in Japan that attracts that many people in the span of just over two months. So some restrictions are necessary to ensure their safety."
Mount Fuji is covered in snow for most of the year, but during the summer hiking season many trudge up its steep, rocky slopes through the night to see the sunrise.
The symmetrical mountain has been immortalized in countless artworks, including Hokusai's "Great Wave". It last erupted around 300 years ago.
