Fewer climbers tackled Mount Fuji during this year's hiking season, preliminary figures show, after Japanese authorities introduced an entry fee and a daily cap on numbers to fight overtourism.

Online reservations were also brought in this year by officials concerned about safety and environmental damage on the country's highest mountain.

The number of climbers fell by 14 percent between early July -- when the volcano's hiking trails opened for the summer -- and early September, according to the environment ministry.

To calculate its preliminary figures, the ministry used infrared devices installed on the four trails.

It comes despite Japan welcoming a record influx of foreign visitors, with nearly 18 million tourists entering the country in the first half of 2024.

Officials raised the alarm last year about overtourism at the once-peaceful pilgrimage site, with the local governor of Yamanashi region warning that "Mount Fuji is screaming".

This summer the environment ministry counted around 178,000 climbers, compared to more than 200,000 the previous year and before the pandemic.

Gates to the trails were closed on Tuesday, marking the end of the hiking season. The preliminary data runs to September 4 and will be updated on a later date, a ministry official told AFP on Wednesday.

The mountain is covered in snow most of the year but during the summer many trudge through the night to see the sunrise from the 3,776-meter (12,388-foot) summit.

This year, an entry fee of 2,000 yen ($14) plus an optional donation was charged on the popular Yoshida Trail, with numbers capped at 4,000 per day. The three other trails remained free.

Concern had been raised that some climbers were sleeping on the trail or starting fires for heat, while others became sick or injured after trying to reach the summit without breaks.

Mount Fuji is about two hours from central Tokyo by train and can be seen for miles around.

The majestic mountain is a symbol of Japan that has been immortalized in countless artworks, including Hokusai's "Great Wave".



Italy Oyster Farmers Dream of Pearls from Warming Mediterranean

Pearls may soon be cultivated in European seas for the first time ever, as Italian oyster farmers seek to exploit an unexpected opportunity offered by the rapidly warming Mediterranean.

In late 2023, the first specimens of Pinctada radiata, a pearl oyster native to the Red Sea, were spotted in the Gulf of Poets, a popular tourist area around 100 kilometers (62 miles) from Genoa on Italy's north-western coast.

Less than a year later, they are proliferating in what have always been some of the Mediterranean's coldest waters, more normally associated with other types of oyster used for food rather than jewellery.

"We are looking into the possibility of producing cultivated pearls here," said Paolo Varrella, the head of a cooperative that has been breeding food oysters in the area since 2011.

The group has already made contact with pearl oyster farmers in Mexico to get tips on production techniques, Varrella said.

"The Pinctada radiata has been reported in the Ionian Sea around the island of Sicily since the 1970s, but only in the last decade has it moved north" to the cooler Tyrrhenian and Ligurian seas that lap the western Italian mainland, said Salvatore Giacobbe, professor of ecology at the University of Messina.

It is the latest in a succession of alien warm-water species to enter the Mediterranean as it heats up due to climate change.

Manuela Falautano, a scientist at the Italian environmental research and protection institute ISPRA, said this trend had seen "an exponential increase" in the last decade.

Some of these species are aggressive and disrupt delicate ecosystems. In a few cases, such the spotted puffer fish and the scorpion fish, they are also dangerous to humans.

The 2.5 million square kilometer (970,000 square mile) expanse of water that separates southern Europe from Africa and the Middle East is heating up faster than the average of the world's seas, Falautano said.

BIG MONEY

Pearl production, more readily associated with Polynesian atolls than the northern Mediterranean, has an annual global turnover of 11 billion dollars, and Italian oyster farmers are keen to cash in.

Adriano Genisi, a pearl importer for more than 30 years, said the Radiata may produce gems similar to Japan's renowned "Akoya" pearls which have a diameter of 5-9 millimeters and a white color with shades of grey, pink and green.

If all goes well the first pearls could be harvested in about a year, he said.

The rising temperature of the Mediterranean is also blamed for an increase in violent storms such as the one that sank the luxury yacht of British tech entrepreneur Mike Lynch off Sicily last month, killing six passengers and the boat's cook.

Franco Reseghetti, a researcher at Italy's National Institute for Geophysics and Vulcanology, said measurements taken in the Tyrrhenian in December at depths of between 300 and 800 meters showed the highest temperatures since 2013, and he expected to see a further increase this year.

"The huge amount of energy behind this heating can act as a fuel for devastating atmospheric phenomena" such as the violent storm which appeared to have sunk the yacht off Sicily, Reseghetti said.
