Kagawa Prefecture - 香川県

map of kagawa prefecture

Kagawa Prefecture, located in the northeast corner of Shikoku, is home to Japan’s oldest national park, the Seto Inland Sea National Park.

The prefecture resembles the shape of a half-moon, with the Sanuki Mountain Range to the south and the Sanuki Plain in the north.

The prefecture is Japan’s smallest in size, and the plains and mountains account for about the same amount of land area. The length of the sea coast stretches more than 700 km, and the prefecture’s numerous islands are dotted throughout the Seto Inland Sea in a captivating natural setting.

Throughout the year the Seto Inland Sea is blessed with a high ratio of sunny days and very little rainfall, making it one of the driest regions in Japan.
