Hokkaido is the northernmost island of Japan, with Sapporo as its capital. It offers a wide variety of attractions, from rich nature to art, culture, and historic architecture, blending Eastern and Western influences seamlessly. The island is full of rice fields, flower fields, and countless mountains of varying heights. It is also one of the world's most famous destinations for winter sports, with numerous ski resorts, as well as well-known onsen towns that showcase traditional Japanese charm.
Hokkaido's climate is generally very cold in winter and pleasantly mild in summer. The eastern part of the island tends to be colder than the west, and mountain areas can be much colder than the lowlands. Although Hokkaido isn't a very large island, its central mountain ranges and the three seas surrounding it create noticeable climate differences from one part of the island to another.
However, Hokkaido is largely unaffected by the mid-year rainy season that other parts of Japan experience, so travelers visiting during that time rarely encounter heavy rain. This is why many Japanese travelers choose to visit from mid-year through summer. Hokkaido is also known for having some of the most beautiful beaches in the country.
