The quake, which shook the central and eastern regions including the Tokyo metropolitan area at around 10:28 pm Friday, registered lower 6 on the Japanese seismic intensity scale of 7 in part of Yamanashi Prefecture, Kyodo News reported.

Such a level of shaking was last recorded in the prefecture in 1924, though the temblor was not related to volcanic activity at Mt. Fuji, according to the Japan Meteorological Agency.
