Chōshū Dejima, Artificial island in Shimonoseki, Japan.
Chōshū Dejima is a fan-shaped artificial island in the Hibiki Sea connected to the mainland by a modern bridge. The site is compact with open spaces offering views of Shimonoseki harbor and its surrounding waters.
The island was built in the 17th century during the Edo Period as a controlled trading post under Japan's isolation policy. It allowed the government to manage foreign trade contacts while maintaining strict control over who could access the mainland.
The island served as a meeting place where Japanese officials and European traders exchanged goods and technical knowledge. Visitors walking through the space can sense how this controlled interaction shaped early cross-cultural contact.
The island is accessible via a bridge from the adjacent park area, with open walkways for exploration. Clear weather provides the best views of the harbor and surrounding water.
The island's layout was deliberately designed with physical barriers to separate foreign traders from local residents and maintain security. This spatial division reveals how carefully the Edo government managed foreign presence on Japanese soil.
