Earthquakes and tsunamis

As Japan is in a major earthquake zone you should familiarise yourself with safety procedures in the event of an earthquake or tsunami, and take note of instructions in hotel rooms. Tsunami warnings are published by the Japan Meteorological Agency.

To learn more about what to do before, during and after an earthquake, see the website of the US Federal Emergency Management Agency.


On 15 September 2015, the Japanese Meteorological Agency issued a level 3 warning (don’t approach the volcano) for Mount Aso, Kumamoto prefecture. Mountain Sakurajima in Kagoshima prefecture and Mount Hakone in Kagagawa prefecture are also currently at warning level 3.

Check latest volcano warnings on the website of the Japanese Meteorological Agency.

Tropical cyclones

The tropical cyclone (typhoon) season runs from June to December with most activity between July and September. Southern parts of the country are particularly at risk. You should monitor the progress of approaching storms on the website of the Japan Meteorological Agency.

Typhoons that hit Japan are often accompanied by damaging high tides. People living in coastal areas are particularly at risk. Landslides and flooding can occur anywhere. The dangers increase when an earthquake occurs shortly after a typhoon has saturated an area.
