Answer:
The rivers and harbors around Tokyo are prone to flooding from precipitation and typhoons. As the city developed, more land was paved over, leaving less exposed soil to soak up the rain. As a result, the risk of floods increased.
Step-by-step explanation:
Tokyo's asphalt roads and pavements are major contributors to the cities risk of flooding. Because of the cities' size, large portions of once permeable land got covered by the cities growing roadways. This resulted in rainwater being unable to seep into the soil and instead forced this rainwater to flow directly into Tokyo's surrounding waterways, causing overflows. Additionally, climate change has been contributing to an increase in typhoons in the city and, as a result, more rainfall.
