Tokyo is susceptible to flooding even with the smallest amounts of abnormal rain, so any increase could lead to flooding. The average rainfall in Tokyo is shown in Figure 1. Japan has a drier winter than it does summer and has most of its rainfall in September. When the flooding occurred in July, the water levels were already higher on average than they were previously in the year since the summer and fall is wetter than the winter. So the rainfall that occurred in July had a larger impact than it would have had in January when average precipitation is lower. This is because the water tables are more full in July, so excess water does not have as many places to go. However, the flooding was not as detrimental as it might’ve been come September.
