The Japanese Meteorological Agency noted that the earthquake that hit Japan at 4:16am registered an upper 5 on the Japanese earthquake intensity scale of 7 in Kisarazu and a lower 5 in Kimitsu, both in Chiba Prefecture and 4 in areas including Tokyo’s Chiyoda and Shinagawa wards.
There are no warnings regarding tsunamis issued by the authorities.
According to the upper-five scale definition, it is a situation in which people find it difficult to walk.
Since 2012, it has been the first time Chiba Prefecture has been rattled by an upper-5 earthquake, said the agency, warning further that a similar scale earthquake could occur for about a week.
The earthquake measured 4 in Mihama Ward in the city of Chiba and in some wards in Yokohama and Kawasaki.
Two women were minorly injured in Chiba Prefecture, with two others hurt in Kanagawa Prefecture, including a man who suffered injuries from a falling ceiling light while sleeping.
No casualties were reported from Tokyo, according to The Japan Times.
Reports noted that the railway services that run through Chiba Prefecture, including the Uchibo and Sotobo lines, were canceled or delayed.
Roof tiles were dislodged in Kisarazu, and scattered on the ground while dozens of elevators, mostly in high-rise condominium buildings in Tokyo as well as Chiba and Kanagawa prefectures, stopped automatically due to the earthquake.
According to the elevator manufacturing and maintenance company Elevator Systems, nobody was reported to be trapped inside.
The quake originated in southern Chiba Prefecture at a depth of around 40 kilometers. The agency initially reported a magnitude of 5.4 but later revised it to 5.2.
The residents were terrified after the quake, although there were no serious injuries in the aftermath of the jolt.
