Japan's Mount Fuji Bare Again after Fleeting Snow | NASA Earth Observatory
Ground and aerial photos from November 6 showed Mount Fuji with a fresh coating of snow on its peak. A local office of the Japan Meteorological Agency (JMA) officially confirmed the presence of snow on November 7, according to news reports; clouds had obstructed their view of the mountain the previous day.
By the time the Operational Land Imager (OLI) on the Landsat 8 satellite acquired this top image on November 9, the new snow appears to have melted. For comparison, an image from October 30, 2023 (bottom), acquired by the OLI-2 on Landsat 9, shows the mountain clad in white. That year, the first snow on Mount Fuji came on October 5, a more typical time for this annual milestone.
The snow’s late arrival follows periods of exceptional warmth in Japan. The average summer temperature, from June to August 2024, was 1.76 degrees Celsius (3.17 degrees Fahrenheit) higher than the 1991–2020 average, according to JMA weather station observations. Those temperatures tied summer 2023 as the country’s hottest summer since comparable records began in 1898.
Above-average heat continued into the fall. Across Japan, over 120 million people experienced “unusual heat” in the first week of October 2024, reported Climate Central, when more than 70 Japanese cities recorded temperatures of 30°C (86°F) or higher. Warmth was also felt at Mount Fuji’s summit. According to news reports, it prevented early-season precipitation from falling as snow.
The volcano’s first snow of the season fell in early November 2024—the latest in a 130-year record—only to apparently vanish within a few days.
Mount Fuji is an active stratovolcano located on the Japanese island of Honshu with a summit elevation of 3,776.24 m (12,389 ft 3 in). It is the tallest mountain in Japan, the second-highest volcano located on an island in Asia and seventh-highest peak of an island on Earth. The mountain is located about 100 km (62 mi) southwest of Tokyo and is visible from the Japanese capital on clear days. Mount Fuji's exceptionally symmetrical cone, usually covered in snow for about five months of the year, is commonly used as a cultural icon of Japan and is frequently depicted in art and photography, as well as visited by sightseers, hikers and mountain climbers. Mount Fuji last erupted between 1707 and 1708.
