Dejima, a small fan-shaped artificial island in Nagasaki, was for more than two centuries Japan’s sole point of contact with the Western world. During the Edo period, when Japan closed itself to foreigners under the sakoku isolation policy, the Dutch East India Company was confined to this tiny island, making it the country’s only window onto Western trade, science and culture — knowledge that flowed into Japan as ‘Dutch learning’ (rangaku). Though later swallowed by land reclamation, Dejima has been meticulously restored, and today you can walk its recreated streets among reconstructed warehouses, the Dutch chief factor’s lavish residence, offices and gardens, furnished with period rooms, imported goods and exhibits that vividly bring this unique chapter of history to life. Fascinating and educational, Dejima is one of Nagasaki’s most rewarding historical sites.

Tips
Take time to go inside the restored buildings and period rooms rather than just walking through, and use the English exhibits to appreciate how Dejima was Japan’s only window to the West. It’s very central, so combine it with the nearby Dutch Slope and Glover Garden for a half-day of Nagasaki’s international history.
