A magnitude 5.6 earthquake struck eastern Yamanashi Prefecture on the night of June 26, 2026, injuring 13 people across three regions [1].
The event highlights the persistent seismic vulnerability of the Fuji Five Lakes area, where tectonic movements can cause significant structural damage and human injury.
The earthquake occurred at approximately 22:28 JST [1]. According to reporting, the hypocentre was located at a depth of 20 km [1]. The strongest shaking was recorded in Kawaguchiko-machi, which reached a maximum observed intensity of Shindo 6- [1]. In Otsuki-shi, the observed intensity was Shindo 5+ [1].
Authorities said there were 13 injuries [1]. Eight people in Yamanashi Prefecture sustained light injuries [1]. Additionally, three people were injured in Shizuoka Prefecture, and two were injured in Kanagawa Prefecture [1].
Beyond the human toll, the shaking caused a sign to fall in a city centre [2]. The quake was generated by tectonic movement along a fault located beneath the Fuji Five Lakes region [1].
In response to the activity, the Japan Meteorological Agency issued an advisory. The agency said there was a heightened alert for Shindo 6- earthquakes for approximately one week [1].

The occurrence of a Shindo 6- earthquake in the Fuji Five Lakes region underscores the active nature of local fault lines. Because this area is a major tourist destination and residential hub, the Japan Meteorological Agency's week-long alert indicates a concern for potential aftershocks that could further destabilize damaged structures or cause new injuries.
