Strong Quake Jolts Central Japan
A magnitude 5.6 earthquake struck eastern Yamanashi Prefecture at 10:29 p.m. on June 26, 2026, sending strong tremors across the Kanto region including parts of Tokyo. The Japan Meteorological Agency recorded the epicenter in the eastern part of Yamanashi at a depth of approximately 20 kilometers. Shaking reached lower 6 on the Japanese seismic intensity scale in Fujikawaguchiko, making it difficult for people to stand, while upper 5 was felt in Otsuki and lower 5 in areas of Shizuoka and Kanagawa.
Transportation Disruptions
The Tokaido Shinkansen line operated by JR Central was suspended between Tokyo and Toyohashi stations in both directions immediately after the quake. Services resumed around 1:17 a.m. on June 27. JR East reported automatic halts on the Tohoku, Joetsu, and Hokuriku Shinkansen lines that lasted about 15 minutes before normal operations resumed. Some expressways in the region were closed for safety inspections.
