A strong earthquake struck Tokyo and its surrounding areas, including Ibaraki, Saitama, and Tochigi prefectures, triggering Japan's first emergency earthquake warning in nearly a year at 09:08 on March 21. The quake, preliminarily measured at magnitude 5.3, was felt across the Kanto region, prompting alerts and causing buildings in Tokyo to shake. The Japan Meteorological Agency issued the warning early on March 21, citing an intensity of lower 5 on Japan's seismic scale of 7. Despite the significant tremor, there have been no immediate reports of damage or injuries. Residents and commuters experienced the quake differently, with some noting the alarming quake notifications on their phones, while others barely felt the shaking.
