On average, snow began to form on Japan's highest mountain on Oct. 2, and the latest it has been recorded before this year was in 1955 and 2016, when it fell on Oct. 26.
"Rain is likely to temporarily fall near Mount Fuji on November 6," the tenki.jp forecasting website, run by the Japan Meteorological Association, was quoted.
"Cold air will enter and change from rain to snow near the summit. The weather will gradually clear up and the first snow on the mountain can be seen on the morning of the 7th," he added.
Another company, Weather News, also reported that "the first snowfall will likely be delayed until November."
At Lake Kawaguchi, a favorite volcano viewing spot, French visitor Hugo Koide said it was "quite shocking to see at this time of year that there is no snow."
The 25-year-old, who visited the area in autumn as a child, said he remembered how Fuji "was always covered in snow".
"I'd go up in a T-shirt and shorts. Somehow I don't feel the same way," said Australian traveller Jason Le.
"I think around the world it affects everyone. We're from Australia and what you see is it gets hotter in the summer months and colder earlier," he said. | BGNES
