Typhoons and concentrated heavy rain

Typhoons frequent Japan between the summer and fall season. These storms could trigger floods and landslides caused by concentrated heavy rain and damages caused by strong winds. Please make sure to avoid going outside without compelling reason when there are warnings of such storms. Damages caused by concentrated flash torrential rain and regional downpour occur all across Japan. Be prepared by being aware of where you would need to evacuate if such disasters should occur.
In the event of a typhoon or severe rain storms, be sure to stay updated on weather information through the radio, television, internet or other means – it is particularily important to stay updated as the City of Sapporo may at some point issue any of the following evacuation warnings.
