Tokyo District Meteorological Observatory (東京管区気象台, Tōkyō Kanku Kishōdai), abbreviated as TDMO, [1] is one of the five District Meteorological Observatories of the Japan Meteorological Agency. It has jurisdiction over the Kantō and Chūbu regions: Tokyo, Kanagawa, Chiba, Saitama, Ibaraki, Tochigi, Gunma, Yamanashi, Nagano, Niigata, Shizuoka, Aichi, Gifu, Mie, Ishikawa, Toyama and Fukui, and is responsible for acquiring meteorological, hydrological, seismological and volcanological data and forecasting local weather conditions in those areas (except weather forecast in Tokyo) through its local meteorological observatories. It also fills the role of Region Central Forecast Office (地方予報中枢官署, Chihō Yohō Chūsū Kansho) for the Kantō region. The TDMO is based inside the JMA Meteorological Satellite Center located in Kiyose, Tokyo. [2]

Chūbu region Region of Japan

The Chūbu region, Central region, or Central Japan is a region in the middle of Honshū, Japan's main island. In a wide, classical definition, it encompasses nine prefectures (ken): Aichi, Fukui, Gifu, Ishikawa, Nagano, Niigata, Shizuoka, Toyama, and Yamanashi.

Hokuriku region Subregion in Chūbu, Japan

The Hokuriku region was located in the northwestern part of Honshu, the main island of Japan. It lay along the Sea of Japan within the Chūbu region, which it is currently a part of. It is almost equivalent to Koshi Province and Hokurikudō area in pre-modern Japan. Since the Heian period until the Edo period the region was a core recipient of population, the population grew to be much larger proportionately than it is today, despite the rural character. With the growth of urban centers in the 20th century, particularly Tokyo and Chūkyō, the Hokuriku has steadily declined in importance to become relative backwaters. The region is also known for traditional culture that originated from elsewhere that has been long lost along the Taiheiyō Belt.

Japan Meteorological Agency National meteorological service of Japan

The Japan Meteorological Agency, abbreviated JMA, is an agency of the Ministry of Land, Infrastructure, Transport and Tourism. It is charged with gathering and providing results for the public in Japan that are obtained from data based on daily scientific observation and research into natural phenomena in the fields of meteorology, hydrology, seismology and volcanology, among other related scientific fields. Its headquarters is located in Minato, Tokyo.

Komatsu Airport Airport in Ishikawa, Japan

Komatsu Airport is an international airport located 4.2 km (2.6 mi) west southwest of Komatsu Station in the city of Komatsu, Ishikawa Prefecture, Japan. It is the largest airport in the Hokuriku region and serves the southern portion of Ishikawa Prefecture including the capital of Kanazawa, as well as Fukui and the northern portion of Fukui Prefecture.

Toyama Chihō Railway Railway company in Toyama, Japan

The Toyama Chihō Railway is a transportation company in Toyama, Toyama Prefecture, Japan. The company is commonly known as Chitetsu (地鉄). This private company operates railway, tram, and bus services in the eastern part of the prefecture. It also operates as the agency of All Nippon Airways in Toyama area. The company has its root in Toyama Electric Railway founded in 1930. The current company was founded in 1943, when all the private and public operators of railway, tram, and bus lines in the prefecture were merged into one. In 1950, it founded Kaetsunō Railway, planning to build the railway line that links Toyama and Ishikawa. Chitetsu handed over its networks in the western part of Toyama Prefecture, although the plan never came to fruition.

Cherry blossom front

The cherry blossom front refers to the advance of the cherry blossoms across Japan. The Japan Meteorological Agency records the opening and full bloom of the blossoms from Kyūshū in late March to Hokkaidō in the middle of May. The advancing front is also the subject of regular reports by the major news agencies. The cherry blossom is of great public interest in Japan due to its symbolism and the custom of flower viewing known as hanami.

District Meteorological Observatory

The District Meteorological Observatory, abbreviated to DMO, is a type of JMA weather stations and a part of its local offices. There are five District Meteorological Observatories in Japan. They're responsible for regional observation of the atmosphere, earthquakes, volcanos and gathering up data on them in order to announcing information to the public that provides against various natural disasters. They also supervise Local Meteorological Observatories and other weather stations within each district area.

Local Meteorological Observatory

The Local Meteorological Observatory, abbreviated to the LMO, is a type of JMA weather station and a part of its local offices. JMA set up five LMOs in Hokkaido, three in Okinawa and one in another each prefecture which has neither District Meteorological Observatory nor Marine Observatory; thus Local Meteorological Observatories count 50 in Japan. They are responsible for local weather services and some of them manage local weather stations.

The Okinawa Meteorological Observatory is a JMA located in Naha, Okinawa. It is responsible for weather services in Okinawa region and operates three Local Meteorological Observatories as well as an Aviation Weather Station.

The following lists events that happened during 2016 in Japan.

Typhoon Georgia (1959) Pacific typhoon in 1959

Typhoon Georgia is one of the more impactful typhoons that struck Japan, as well as one of the few observed tropical cyclones that made direct landfall in Russia as a tropical storm. A low pressure system formed in the vicinity of Guam on August 10 which formed Tropical Depression Fran, and a new low-level center formed from a fracture of a trough that split newly formed tropical depression in the midnight of August 12. The newly formed low level center was classified as a tropical storm and was named Georgia hours later by the Joint Typhoon Warning Center. The new tropical storm was tracked by Japan Meteorological Agency shortly afterwards and Georgia rapidly intensified into a typhoon. On the next day, Georgia further intensified after passing Chichi Jima and reached peak sustained winds of 110 knots (57 m/s) while quickly accelerating in the north-northwest direction before striking Chūbu region in Japan on evening of the same day as a weakening typhoon. After emerging on the Sea of Japan as a tropical storm on August 14, Georgia made landfall in Soviet Union as a tropical storm at the afternoon of the same day, before transforming into an extratropical storm quickly after landfall. Remnants of Georgia was last noted on Heilongjiang, China on August 16.

2015 Ogasawara earthquake is an earthquake that occurred on May 30, 2015. A magnitude 7.8 earthquake struck offshore of Japan 189 km (117 mi) west northwest of Chichi-jima in the Ogasawara Islands on May 30 at a depth of 664.0 km (412.6 mi). The shaking of the earthquake was observed almost all over Japan. It is believed that this was due to a deep-focus earthquake. This earthquake was one of the largest deep-focus earthquakes recorded worldwide.

Typhoon Gilda (1974) Western Pacific typhoon in 1974

Typhoon Gilda, known in the Philippines as Typhoon Deling and in Japan as Typhoon No. 8 in 1974, was a destructive, deadly, costly and long-lived tropical cyclone that left over 145 confirmed deaths over Japan and South Korea, mostly due to torrential rainfall that induced landslides, all generated by the typhoon and its associated meiyu front. The eighth named storm and third typhoon of the 1974 Pacific typhoon season, the system was first noted by the China Meteorological Agency as an area of convection embedded on a trough, to the north of Enewetak Atoll on June 25. It was named Gilda on June 30 as it strengthened to a tropical storm. Under a favorable environment, it strengthened to a typhoon two days later as it moved northwestward. Another trough pulled Gilda poleward while changing less in intensity, until it intensified to a Category 2 typhoon as it battered the Ryukyu Islands at its peak. Increasing wind shear gradually weakened the system; however, it remained as a minimal typhoon until it passed through the southern tip of South Korea on July 6, where it weakened to a tropical storm. Colder waters in the Sea of Japan and high shear further degraded Gilda, until it transitioned to an extratropical low as it made landfall near Hokkaido on July 9. The remnants of the system briefly intensified near the Kuril Islands before weakening and dissipating on July 17 over the Sea of Okhotsk.

1982 Nagasaki flood

The 1982 Nagasaki flood was caused by a cloudburst that occurred mainly in Nagasaki, Japan in July 1982.
