An earthquake with a preliminary magnitude around 5.9 strikes eastern Japan early Sunday, shaking areas including the Tokyo region. Japan’s weather and disaster agencies report at least five people are injured, with additional injuries under assessment. There is no danger of a tsunami.

The quake’s epicenter is reported in or near southern Ibaraki Prefecture at roughly 68–70 kilometers depth, an area prone to frequent earthquakes. In parts of Ibaraki and central Tokyo, seismic intensity reaches around lower levels on Japan’s scale, while mobile phone quake alerts are reported. Disruptions include delays to some express and local train services serving Tokyo and Narita Airport, while Shinkansen bullet trains are reported to be operating normally.

Outlets differ mainly in reported injury totals and local impacts. One outlet reports injuries affecting Ibaraki, Chiba and Saitama, while another reports a higher number of mostly minor injuries. Additional effects mentioned include emergency task force assessments by the government, possible water-pipe damage in Tokyo, and power outages reported by one source, alongside assurances that nuclear facilities remain secure.
