Most typhoons hit Japan between May and October with August and September being the peak season. Typhoons later in the season tend to be stronger than typhoons earlier in the season. In Japan, typhoons are numbered rather than being given a personal name. For example, the twelfth typhoon of the year is known as typhoon number 12. A typhoon moves at a relatively slow pace (around 20 km/h), and its path can be predicted quite accurately.
