Lightning Protection of the Mt. Fuji Weather Station

In the Mt. Fuji weather station, lightning strikes frequently, so it is difficult to place the solar panels safely for long term. Also for the stable observation and research, the protection of lightning strikes for the outside experimental instruments is necessary. This research focuses on the clarification of the characteristics of lightning strikes at the Mt. Fuji weather station and suggests the countermeasures. The main countermeasures are two things; how to suppress invasion of lightning surge into the building using the return electromagnetic shielding at the Faraday cage damages, and how to suppress the lightning surge using the lightning protection cable which connect the outside observation equipments and the Faraday cage.
