The most feared thing in a mountain by climbers and workers is lightning. The project started with the idea to inform people about the approach of cumulonimbus clouds, so people can countermeasure and avoid lightning strikes. [Imafuji] has a field mill installed at the Tarobo at Gotemba New 5th Station to observe electric field strength. As part of the test, a lightning alert will be issued to notify areas within a radius of approximately 5 km from Tarobo of the approach or passage of cumulonimbus clouds. With the goal of leading to actions to protect affected people, we are collecting and investigating data related to cumulonimbus clouds and lightning around Mt. Fuji. This section will provide a record of activities related to the project.

Weather Observation Station Project
Weather instruments have been installed at the summit and along various trails of Mt. Fuji to conduct comprehensive weather observations. Until now, general climbers have had access only to weather observation data from the Japan Meteorological Agency’s AMeDAS station at the summit. However, the data from the Fuji Summit AMeDAS station have been limited to just three elements: temperature, relative humidity, and atmospheric pressure, with sunshine duration observed during the summer. Information on precipitation, wind direction, and wind speed has not been provided. In addition, around the Mt. Fuji area, only nine AMeDAS stations are available (in Kawaguchiko, Yamanaka, Gotemba, Mishima, Fuji, Shiraito, Nanbu, Kiriiwa, and Furuze). For climbers who encounter rapidly changing weather conditions on Mt. Fuji, the need for weather observation information from both the summit and various trails has been essential. To meet this need, weather equipment has been set up around Mt. Fuji, providing critical information for safe climbing. This platform will be used to share records and updates about the activities of the project.
Signages are installed at the summit of Mt. Fuji and the surrounding hiking trails so distribute real-time weather information. Weather information is already available before your climb. Check and replenish your climbing gear before the ascent. Also, those who aren’t around can get a grasp of the real weather conditions of Mt. Fuji from afar. Here is
