Rain falls year round but June and early July is the primary rainy season. however, Hokkaido is much drier than the Tokyo area. Rainfall is usually intermittent with sunshine. Typhoons are usually occur in September or October but rarely last more than one day.

Lightweight cottons and linens are required all summer in most areas. There is much less rainfall than occurs in Western Europe.
