It was the day when the South American Andean Amazon Expedition of Tokyo Doshisha University sailed 130km from the headwaters of the Amazon River for the first time in the world in 1965.
The total length of the Amazon River is 6992km, but 130km by small boat from the headwaters was a world record at that time.
There used to be a manned weather station on the summit of Mt. Fuji, a World Heritage Site.
It was the Nonaka weather station opened on August 30, 1895 at Fujisan Kengamine.
This weather station was built by Itaru Nonaka (1867-1955) of the Meteorological Society of Japan with private fortune, and was a 20-square-meter wooden weather station built by climbing a mountain with construction materials and weather equipment on its back.
This meteorological observatory became the Mt. Fuji weather station of the Japan Meteorological Agency from 1923, but radar observation was abolished in 1999 due to advances in automatic observation technology, and it became an unmanned weather station from October 1, 2004.
Currently, Mt. Fuji Special Area Meteorological Observatory is observing atmospheric pressure, temperature, humidity, etc.
In addition, the old radar dome will be relocated to the Mt. Fuji Radar Dome Museum in Fujiyoshida City, Yamanashi Prefecture, and can be visited.
