Kanto Auto Works plant. Later, the company replaced Yokosuka for car assemby with the Higashi-Fuji (established in 1968) and Iwate (established in 1993) plants. Kanto Auto Works was a public company until 2011 when, following the 2011 Tohoku earthquake, Toyota announced it would make it a wholly owned subsidiary. On July 1, 2012, Kanto Auto Works and two other Toyota subsidiaries (Central Motors and Toyota Motors Tohoku) were combined into a single company called Toyota Motor East Japan, Inc. Kanto Auto Works In April 1946, Kanto Auto Works was established in Yokosuka, Kanagawa, Japan, as an independent company called "Kanto Electric Motor Works"
2011 Tōhoku earthquake and tsunami and south. From the averaged coupling coefficient of 0.5–0.8 in the source area and the seismic moment, it was estimated that the slip deficit of this earthquake was accumulated over a period of 260–880 years, which is consistent with the recurrence interval of such great earthquakes estimated from the tsunami deposit data. The seismic moment of this earthquake accounts for about 93% of the estimated cumulative moment from 1926 to March 2011. Hence, earthquakes with magnitudes about 7 since 1926 in this area only had released part of the accumulated energy. In the area near the trench, the coupling coefficient
