Miyagi Prefecture also continued to experience water supply issues, with about 5,000 households there experiencing supply cuts.
Defense Minister Nobuo Kishi had earlier directed the Self-Defense Forces to gather information on the scope of the damage and be prepared to respond immediately. The Meteorological Agency is urging caution due to the potential for landslides, as a storm warning has been issued for much of the Kanto and Tohoku regions for Monday.
The earthquake registered a strong 6 on the Japanese seismic intensity scale to 7 in parts of Miyagi and Fukushima prefectures.
It also jolted Tokyo, where it registered a 4 on the Japanese scale, and was the strongest to hit the region since April 7, 2011, the Meteorology Agency said. The epicenter was off the coast of Fukushima, about 220 kilometers (135 miles) north of the capital. Its focus was estimated to be at a depth of about 55 kilometers.
