Japan alerts nation to ongoing earthquake risk after the magnitude-5 event. The tremor revived memories of past Tokyo tremors.

Where the quake was felt and immediate checks

The epicentre was located in southern Ibaraki Prefecture. The quake originated at roughly 48 km depth.

Shaking was strongest in Ibaraki and Tochigi prefectures. Nearby Fukushima, Chiba and Saitama experienced noticeable but weaker tremors, Filmogaz.com reported.

Authorities said there was no tsunami risk. Early inspections found no injuries or major structural damage.

Transport and critical infrastructure

Several bullet train services between Sendai and Tokyo were delayed for hours. Operators conducted safety inspections before resuming service.

Chief Cabinet Secretary Minoru Kihara said no irregularities were reported at nuclear facilities. Prime Minister Sanae Takaichi ordered close coordination with local officials.

Why Japan experiences frequent quakes

Japan sits on the Pacific Ring of Fire where major tectonic plates converge. The Pacific, North American, Eurasian and Philippine plates all interact near Japan.

The constant plate movement produces frequent seismic activity. The nation maintains strict building standards and widespread earthquake drills.

Historical context

Officials and citizens remain mindful of the 2011 disaster. That quake and tsunami killed more than 18,000 people and led to meltdowns at Fukushima reactors.

The country continues recovery and resilience efforts. Preparedness measures aim to reduce harm from future events.
