Despite its small size, Japan has a variable climate. Tokyo has a climate similar to New York City. Summers (June, July and August) are hot and humid, while winters are freezing and snowy. Tokyo's weather is best in springtime and autumn, as both seasons offer a respite from the extreme conditions they precede and follow.
The weather in Osaka is more temperate. Winters are pretty mild, with highs above 50°F (10°C). Snowfall is rare and usually light. On the other hand, summers can be hot, moist and rainy. Temperatures can get as high as 95°F (35°C) with very high humidity. Rainfall is also abundant in Osaka.
Sapporo has a humid continental climate – hot and wet summers and chilly, snowy winters. Sapporo is a former Winter Olympic Games city and can get up to 72 inches (1,829mm) of snow in January alone. Skiing is, therefore, a popular activity in the area.
