Islands and Venues

Seto Inland Sea

The Seto Inland Sea lies between three of the four main islands of Japan (Honshu, Shikoku and Kyushu), extending roughly 450 km east to west and anywhere from 15 km to 55 km south to north. This region, which is often referred to as Setouchi in Japanese, is noted for its scenic beauty. Islands lie scattered across the sea’s tranquil waters, white sandy beaches rim its shores, pine groves provide welcome shade, and rice paddies terrace the hillsides. The first Westerners to gaze upon the area after it was opened in the mid-nineteenth century, including Thomas Cook and Philipp Franz von Siebold, praised its charms in their travelogues. In 1934, the section of the Inland Sea bordered by Kagawa, Okayama and Hiroshima prefectures became Japan’s first national park.

Since ancient times, the Seto Inland Sea has served as a strategic shipping route, carrying not only goods but also peoples and cultures to and from the Kansai area. The islands and coastal regions welcomed this influx of knowledge while, at the same time, developing their own unique culture and traditions. The fact that the region was formed through the workings of both man and nature is one of its many charms.

During the 1960s, Japan underwent rapid economic growth, but the development of large scale industries in the Setouchi region exacted a heavy toll in the form of environmental pollution. The rich historical and cultural legacy of the Seto Inland Sea thus reflects both the positive and negative aspects of humankind’s interaction with the natural environment.
