At least 32 people were injured in Tokyo while train services remained disrupted on Friday, a day after what authorities said was the strongest earthquake in a decade to hit the city.
A powerful earthquake of 5.9 magnitude jolted the Japanese capital at 10.41 p.m. local time (1341GMT) on Thursday.
The train services were still disrupted on Friday morning, "affecting about 368,000 passengers in total," the Tokyo-based Kyodo News reported.
Many services were delayed or cancelled following the powerful tremor.
Residents have been warned by the Japan Meteorological Agency that "more earthquakes of a similar intensity are possible over the next week or so."
The epicenter of the quake was in the northwestern Chiba province, neighboring Tokyo, at a depth of 75 kilometers (46.6 miles).
The weather agency added that another tremor measuring 3.6 on the Richter scale occurred in the same area early on Friday morning.
