Tourists hoping to climb Mount Fuji using its most popular route will now have to pay a 2,000 yen (£10) charge, to try and limit numbers.
More than 220,000 hikers used this trail between July and September last year.
According to authorities – it led to the paths being too busy, causing a rise in litter, but also instances where people got hurt on the trails.
Officials hope this new charge – as well as restrictions on hiker numbers – will help tackle these problems.
