The Mount Fuji Radar System is a historic weather radar system located on the summit of Mount Fuji, Japan.
The installation was completed on August 15, 1964, [1] and is now recorded on the list of IEEE Milestones in electrical engineering. When first built, the Mount Fuji Radar System was the world's highest weather radar (elevation 3,776 metres [12,388 ft]), and could observe major weather phenomena, such as destructive typhoons, at a range of more than 800 kilometres (500 mi). It was designed by the Japan Meteorological Agency and built by Mitsubishi Electric Corporation.
The system is notable for its advances in weather radar technology, remote control, and difficulty of construction, as it required the transport and assembly of some 500 tons of material during mountain's short summer. It operated at a frequency of 2880 MHz , with output power of 1500 kilowatts, and a pulse width of 3.5 microseconds. Its antenna was a circular dish, 5 meters in diameter, of parabolic shape, rotating at either 3 or 5 revolutions per minute, and housed within a 9-meter radome.
The system was decommissioned in 1999, as it was superseded by weather satellites. The dome, radar dish and support equipment were relocated to a purpose-built museum in Fujiyoshida, Yamanashi in 2001. It was replaced by an automated weather system in 2004. [2]
Mount Fuji is an active stratovolcano located on the Japanese island of Honshu, with a summit elevation of 3,776.24 m. It is the highest mountain in Japan, the second-highest volcano located on an island in Asia, and seventh-highest peak of an island on Earth. Mount Fuji last erupted from 1707 to 1708. 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, which is 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 Aso or Aso Volcano is the largest active volcano in Japan and among the largest in the world. Common use relates often only to the somma volcano in the centre of Aso Caldera. It stands in Aso Kujū National Park in Kumamoto Prefecture, on the island of Kyushu. Its tallest peak, Takadake, is 1,592 meters (5,223 ft) above sea level. Mount Aso is in a fairly large caldera with a circumference of around 120 km (75 mi), although sources vary on the exact distance. It is one of the 100 Famous Japanese Mountains.
Mount Chōkai is an active volcano located on the border of Akita and Yamagata in the Tōhoku region of Japan, and is 2,236 m (7,336 ft) tall. Because of its (roughly) symmetrical shape and massive size, it is also variously known as Dewa Fuji (出羽富士), Akita Fuji (秋田富士) or Shōnai Fuji (庄内富士) depending on the location of the viewer. In addition to being one of the 100 Famous Landscapes of Japan, it is also included as one of the 100 famous mountains in Japan, and famous 100 Geographical Features of Japan. It is surrounded by Chōkai Quasi-National Park. It is also a National Historic Site of Japan, and is regarded as a sacred mountain by followers of the Shugendō branch of Shinto which has the shrine Chōkaisan Ōmonoimi Shrine there and is popular with hikers.

Mount Fuji is a dormant volcano which is the tallest peak in Japan. The latest eruption of Mount Fuji was triggered by an earthquake in 1707. The mountain as it appears now is known as the "New Fuji volcano", which began to erupt about 10,000 years ago. Under the "New Fuji volcano" lies the "Old Fuji volcano", which was active between 100,000 years ago and 10,000 years ago, and the "Komitake volcano", which became active 700,000 years ago.
Mount Iwaki is a stratovolcano located in western Aomori Prefecture, Tohoku, Japan. It is also referred to as Tsugaru Fuji (津軽富士) and less frequently, Okufuji (奥富士) due to its similar shape to Mount Fuji.
