A Kantō earthquake (関東地震, kantō jishin) is a megathrust earthquake occurring in the Kantō region of Japan that originate from slippage in the Sagami Trough. Kantō earthquakes are thought to occur with a 200-year return period.

Only two earthquakes in the Kantō region are thought to be megathrust earthquakes:

  • 1923 Great Kantō earthquake; most common usage
  • 1703 Genroku earthquake

    • Other earthquakes in the Kantō region, which may or may not be due to slippage in the Sagami Trough:

  • The Ruijū Kokushi mentions an earthquake that struck the area in 818
  • 1855 Edo earthquake
