The most recent notable earthquake in Japan was a light offshore quake in the North Pacific Ocean, southeast of the Bōsō Peninsula in Chiba Prefecture.

Quick Scoop

  • The quake occurred off the southeast coast of Tateyama, a city at the southern tip of Chiba Prefecture, facing the Pacific.
  • It was located about 47 km southeast of Tateyama, out at sea in the North Pacific Ocean rather than directly under a major city.
  • The event was categorized as a light magnitude 3.1 earthquake, which is typically felt locally but is unlikely to cause serious damage in Japan’s well-prepared infrastructure.

Latest news angle

  • This quake is one of many small to moderate tremors Japan experiences regularly due to its position on multiple active tectonic plate boundaries.
  • For stronger or tsunami-related quakes, Japanese authorities issue alerts and evacuation guidance through TV, mobile phones, and public loudspeakers very quickly.

If you meant a different quake

If you were asking “where in Japan was the earthquake?” about a specific stronger event (for example, a big one mentioned on TV or social media), the exact location can change from case to case, such as:

  • Offshore in the North Pacific, east of northeastern Japan (Tohoku region).
  • Near the Sea of Japan side, like the Noto Peninsula area in Ishikawa Prefecture in earlier major events.

If you tell roughly when you heard about the earthquake (date or “this morning/last night”) or which region was mentioned, a more precise location can be pinned down.
