Mount Fuji sported its first snowcap of the season on Thursday, five days later than last year and three days later than in an average year, a local weather agency said.
An official from the Kofu Local Meteorological Observatory in Yamanashi Prefecture observed a layer of snow on the summit of the 3,776-meter mountain at around 7:30 a.m.
The observatory said snowfall had been brought by clouds hovering over Japan's highest peak due to a low-pressure system from late Tuesday night into Wednesday.
At 4 a.m. Thursday, the temperature near the mountain's peak fell to minus 2.5 degrees Celsius, according to the Meteorological Agency.
Fujiyoshida, a city at the foot of the volcano, separately announced the mountain's first snowcap the same day.
"We invite everyone to enjoy the beautiful snow-laden landscape," the city said.
Since 2006, the city has been making the announcement in case the Kofu observatory, located roughly 40 kilometers from the mountain, cannot confirm the season's first snowcap due to rain or fog.
