TOKYO — A powerful earthquake jolted eastern Japan before dawn on Sunday, waking residents across the greater Tokyo area and injuring more than 30 people, most of them lightly. Reports of the Tokyo earthquake today show it struck at around 2 a.m. local time, with tremors reaching five prefectures, though authorities confirmed there was no danger of a tsunami.
- Intensity Lower 5 (JMA scale of 7)
- Injuries 37+ across 5 prefectures
- Tsunami No warning issued
- Trains Shinkansen normal · local lines delayed
- Nuclear plants No anomalies reported
Magnitude 5.9, Depth 70 Kilometres
Seismic readings from the Tokyo earthquake today put the preliminary magnitude at 5.9, according to the Japan Meteorological Agency, while the U.S. Geological Survey logged it slightly lower, at 5.8. Both agencies traced the epicentre to southern Ibaraki Prefecture, at a depth of 70 kilometres, a part of Japan that sees earthquakes often thanks to the tangle of tectonic plates meeting beneath the wider Kanto region.

The quake registered a lower 5 on Japan’s seismic intensity scale, which runs from 0 to 7. That level of shaking hit Tsukuba in Ibaraki, along with Adachi Ward in Tokyo, Kawaguchi in Saitama and Urayasu in Chiba. The tremor also set off emergency earthquake alerts on mobile phones across the region and shook central Tokyo hard enough to send people running.
Over 30 Hurt as Residents Scramble From Bed
At least 37 people were injured across the five affected prefectures, according to local fire departments and Japan’s Fire and Disaster Management Agency: 15 in Tokyo, nine in Saitama, eight in Kanagawa, four in Chiba and one in Ibaraki. Injury reports from the Tokyo earthquake today show a familiar pattern for a quake that hit while most people were still asleep: people hurt falling out of bed or colliding with furniture and doors in the dark, rather than by any structural damage.
One of the more serious injuries involved a woman in her 80s in Yokohama, in Kanagawa Prefecture, who fell from her bed and suffered a serious hip injury, the Yomiuri newspaper reported.
Not everyone was asleep when the ground started moving. A 23-year-old man told the Asahi newspaper he felt a sharp vertical jolt while shopping in Tokyo’s Taito district, seconds after an earthquake alert went off on his phone. His first instinct, he said, was to duck away from merchandise that might fall off the shelves around him.
No Tsunami Warning, But Trains Take a Hit
The Tokyo earthquake today never triggered a tsunami warning, despite its strength and shallow depth. The bigger headache turned out to be the morning commute. Express trains serving central Tokyo and Narita Airport, along with several local lines across Japan’s northeast, ran with delays, and railway operators reported disruptions continuing into the following day around Tokyo and neighbouring areas. Shinkansen bullet trains, however, kept running on schedule, operator East Japan Railway Co. said.
Burst Pipe in Koto, Nuclear Plants Unaffected
In Tokyo’s eastern Koto Ward, an underground water pipe ruptured during the quake, sending water gushing across a road, footage aired by public broadcaster NHK showed. Repair crews fixed the pipe and stopped the leak within hours.
Japan’s Nuclear Regulation Authority said it had no reports of anomalies from the roughly dozen nuclear power plants and other facilities handling nuclear material in the region, a reassurance officials were quick to put out, given how closely Japan has watched its nuclear sites for seismic risk since the 2011 Fukushima disaster reshaped safety protocols nationwide.

Takaichi Orders Task Force, Warns of Aftershocks
The government’s response to the Tokyo earthquake today came within hours. Prime Minister Sanae Takaichi wrote on her X account that she had set up a task force to assess possible damage and had instructed officials to gather information and share it with the public. She also urged residents in the affected areas to stay alert for aftershocks of a similar strength.
The Japan Meteorological Agency echoed that warning, telling residents to stay cautious about further moderate quakes for around a week, a standard precaution the agency issues after any quake strong enough to be felt this widely.
A Country Still Rattled From Last Month’s Kumamoto Quake
Sunday’s tremor comes barely a month after a far deadlier one struck Japan’s south. Last month, a magnitude 7.1 earthquake tore through the Kumamoto area on the southern island of Kyushu, killing 38 people and injuring 364 others. Compared to that disaster, the Tokyo earthquake today caused no deaths and comparatively limited damage, but it lands at a moment when Japan’s seismic nerves are already on edge.
For now, life in the capital is settling back to normal. Roads in Mito and Saitama looked orderly by daybreak, NHK footage showed, and the bullet trains never stopped running. Still, with millions of residents jolted awake before sunrise, the Tokyo earthquake today is a sharp reminder of just how active the ground beneath Japan’s biggest city really is.
