This is a list of earthquakes in Japan with either a magnitude greater than or equal to 7.0 or which caused significant damage or casualties. As indicated below, magnitude is measured on the Richter magnitude scale (ML) or the moment magnitude scale (Mw), or the surface wave magnitude scale (Ms) for very old earthquakes. The present list is not exhaustive, and reliable and precise magnitude data is scarce for earthquakes that occurred before the development of modern measuring instruments.
Although there is mention of an earthquake in Yamato in what is now Nara Prefecture on August 23, 416, the first to be reliably documented took place in Nara prefecture on May 28, 599 during the reign of Empress Suiko, destroying buildings throughout Yamato province.Many historical records of Japanese earthquakes exist, and the Imperial Earthquake Investigation Committee was created in 1892 to conduct a systematic collation of the available historical data, published in 1899 as the Catalogue of Historical Data on Japanese Earthquakes. Following the 1923 Great Kantō earthquake, the Imperial Earthquake Investigation Committee was superseded by the Earthquake Research Institute in 1925. In modern times, the catalogues compiled by Tatsuo Usami are considered to provide the most authoritative source of information on historic earthquakes, with the 2003 edition detailing 486 that took place between 416 and 1888.
In Japan, the Shindo scale is commonly used to measure earthquakes by seismic intensity instead of magnitude. This is similar to the Modified Mercalli intensity scale used in the United States or the Liedu scale used in China, meaning that the scale measures the intensity of an earthquake at a given location instead of measuring the energy an earthquake releases at its epicenter (its magnitude) as the Richter scale does.
Unlike other seismic intensity scales, which normally have twelve levels of intensity, shindo (震度, seismic intensity, literally "degree of shaking") as used by the Japan Meteorological Agency is a unit with ten levels, ranging from shindo zero, a very light tremor, to shindo seven, a severe earthquake. Intermediate levels for earthquakes with shindo five and six are "weak" or "strong", according to the degree of destruction they cause. Earthquakes measured at shindo four and lower are considered to be weak to mild, while those measured at five and above can cause heavy damage to furniture, wall tiles, wooden houses, reinforced concrete buildings, roads, gas and water pipes.

The Chūetsu earthquakes occurred in Niigata Prefecture, Japan, at 17:56 local time on Saturday, October 23, 2004. The Japan Meteorological Agency (JMA) named it the "Heisei 16 Niigata Prefecture Chuetsu Earthquake". Niigata Prefecture is located in the Hokuriku region of Honshu, the largest island of Japan. The initial earthquake had a magnitude of 6.6 and caused noticeable shaking across almost half of Honshu, including parts of the Tōhoku, Hokuriku, Chūbu, and Kantō regions.
In Japan, the Earthquake Early Warning (EEW) is a warning issued when an earthquake is detected by multiple seismometers. These warnings are primarily issued by the Japan Meteorological Agency (JMA), with guidance on how to react to them.
This list of 20th-century earthquakes is a global list of notable earthquakes that occurred in the 20th century. After 1900 most earthquakes have some degree of instrumental records and this means that the locations and magnitudes are more reliable than for earlier events. To prevent this list becoming unmanageable, only those of magnitude 6 and above are included unless they are notable for some other reason.
The 1978 Miyagi earthquake occurred at 17:14 local time on 12 June. It had a surface wave magnitude of 7.7, JMA magnitude 7.4, and triggered a small tsunami. The earthquake reached a maximum intensity of Shindo 5 in Sendai and caused 28 deaths and 1,325 injuries.
The 1993 southwest-off Hokkaido earthquake or Okushiri earthquake occurred at 13:17:12 UTC on 12 July 1993 in the Sea of Japan near the island of Hokkaido. It had a magnitude of 7.7 on the moment magnitude scale and a maximum felt intensity of VIII (Severe) on the Mercalli intensity scale. It triggered a major tsunami that caused deaths on Hokkaidō and in southeastern Russia, with a total of 230 fatalities recorded. The island of Okushiri was hardest hit, with 165 casualties from the earthquake, the tsunami and a large landslide.
The 2011 Tōhoku earthquake and tsunami occurred at 14:46 JST on 11 March. The magnitude 9.0–9.1 (Mw) undersea megathrust earthquake had an epicenter in the Pacific Ocean, 72 km (45 mi) east of the Oshika Peninsula of the Tōhoku region, and lasted approximately six minutes, causing a tsunami. It is sometimes known in Japan as the "Great earthquake disaster of East Japan", among other names. The disaster is often referred to in both Japanese and English as simply 3.11.
The 1968 Hyūga-nada earthquake occurred on April 1 at 09:42 local time. The earthquake had a magnitude of Mw 7.5, and the epicenter was located in Hyūga-nada Sea, off the islands of Kyushu and Shikoku, Japan. The magnitude of this earthquake was also given as MJMA 7.5. A tsunami was observed. There were 15 people reported injured. The intensity reached shindo 5 in Miyazaki and Kōchi.
The April 2011 Fukushima earthquake was a potent magnitude 6.6 Mw intraplate aftershock that occurred at 17:16 JST (08:16 UTC) on 11 April, in the Hamadōri region of Fukushima, Japan. With a shallow focus of 13 km (8.1 mi), the earthquake was centred inland about 36 km (22 mi) west of Iwaki, causing widespread strong to locally severe shaking. It was one of many aftershocks to follow the 11 March Tōhoku earthquake, and the strongest to have its epicentre located inland.
The 1994 Kuril Islands earthquake – also known as the Hokkaido Toho-oki earthquake – occurred on October 5 at 00:23:00 local time. The magnitude of this earthquake was put at Mw8.3, or MJMA8.1. The epicenter was located at about 70 km east of Shikotan Island. The shaking and tsunami caused road and building damage. At least 10 people were reported dead.
The 1994 offshore Sanriku earthquake occurred on December 28, 1994, at 12:19 UTC. This was a magnitude Mw 7.7 earthquake with epicenter located in the Pacific Ocean at about 180 km east of Hachinohe, Aomori. Three people were reported dead and more than 200 injured; 48 houses were completely destroyed. Road damage and power outages were reported. Liquefaction occurred in the Hachinohe Port area. The intensity reached shindo 6 in Hachinohe, Aomori, about 187.6 km from epicenter. It could be felt in Tokyo, about 632.9 km from epicenter, with shindo 2. The Japanese Meteorological Agency put the magnitude at MJMA 7.5. Slip associated with this earthquake continued for more than a year and it has been termed an 'ultra-slow earthquake'.
The 1611 Sanriku earthquake occurred on December 2, 1611, with an epicenter off the Sanriku coast in Iwate Prefecture. The magnitude of the earthquake was 8.1Ms. It triggered a devastating tsunami. A description of this event in an official diary from 1612 is probably the first recorded use of the term 'tsunami'.
The 2001 Geiyo earthquake occurred with a moment magnitude of 6.7 on March 24 at 15:27 local time near Hiroshima, Japan. One person in Hiroshima and one person in Ehime were reported dead. About 3,700 buildings were damaged in the Hiroshima area. Liquefaction was observed in Hiroshima and Ehime. Power outage occurred in the prefectures of Hiroshima, Ehime, Okayama, Yamaguchi, and Kōchi. The maximum intensity was shindo lower 6 in Hiroshima. This earthquake could be felt along the eastern and southern coasts of South Korea.
The 1968 Tokachi earthquake occurred on May 16 at 0:49 UTC in the area offshore Aomori and Hokkaido. The magnitude of this earthquake was put at Mw 8.3. The intensity of the earthquake reached shindo 5 in Aomori, Aomori and Hakodate, Hokkaido.
The 1948 Litang earthquake (1948年理塘地震) occurred on May 28, 1948 at 07:11 UTC. It was located near Litang, China. Now situated in the Sichuan Province, Litang County was then called Lihua (理化) County and belonged to the defunct Xikang Province. The earthquake had a magnitude of Mw 7.2, or Ms 7.3.
The 2021 Fukushima-ken Oki earthquake was a very intense and deadly seismic event that struck offshore east of Tōhoku, Japan. The Mw 7.1 or MJMA 7.3 earthquake occurred on a Saturday night at 23:07 JST on 13 February at a shallow focal depth of 51.9 kilometers (32.2 mi). It had a maximum JMA intensity of Shindo 6+ while on the Mercalli intensity scale, it earned a rating of VIII (Severe). The earthquake was followed by multiple aftershocks within less than an hour, three of which registering magnitude 5.3. The earthquake itself has been considered an aftershock of the 2011 Tōhoku earthquake which had occurred almost ten years prior.
The March 2021 Miyagi earthquake was an earthquake that struck offshore east of Tōhoku, Japan on March 20, 2021 at 18:09 JST. The magnitude 6.9 or 7.0 earthquake struck at a depth of 54.0 kilometers (33.6 mi) to 60 kilometers (37 mi). It had a maximum JMA intensity of Shindo 5+ while on the Mercalli intensity scale, it earned a rating of VII. Power outages and some slight damage in Miyagi was reported.
The 1973 Nemuro earthquake, also known as the Nemuro-Oki earthquake in scientific literature, occurred on June 17 at 11:55 local time. It stuck with an epicenter just off the Nemuro Peninsula in northern Hokkaidō, Japan. It measured 7.7 to 7.9 on the moment magnitude scale (Mw ), 8.1 on the tsunami magnitude scale (Mt ) and 7.4 on the Japan Meteorological Agency magnitude scale (MJMA ).
The 2011 Shizuoka earthquake was an earthquake that occurred approximately 42 km north-northeast of Shizuoka City at 22:31, 15 March 2011. The magnitude was Mw 6.0 or MJMA 6.4, and the depth was 9km. The hypocenter of this earthquake is thought to have been near the presumed location of the magma chamber of Mount Fuji. It may have been a triggered earthquake caused by the 2011 Tohoku earthquake, which occurred four days earlier, on 11 March 2011. It was sinistral strike-slip fault earthquake. It had a maximum JMA intensity of Shindo 6+ (Fujinomiya) or VIII (Severe) on the Mercalli intensity scale. The earthquake left 80 people injured, and caused some power outages.
