In this guide, we’ll highlight the main attractions of Dejima and suggest the best ways to enjoy your visit.

1. History of Dejima

Dejima, a man-made island created by reclaiming land from the sea, was completed in 1636 (Kanei 13). Initially, it was referred to as "Tsukishima" (Reclaimed Island) and "Ougijima" (Fan Island) due to its fan-like shape. Before Dejima was built, Nagasaki flourished as a port town welcoming Portuguese ships, constructing Christian churches, and attracting merchants from all over Japan.

However, during Japan’s Sakoku (national isolation) period, Portuguese ships were banned from entering the country. As a result, the Dutch trading post, which had been conducting commerce in Nagasaki, was relocated to Dejima. From that point forward, Dejima became the sole gateway for trade between Japan and Europe, playing a vital role in Japan-Netherlands relations until the end of the Edo period. Although the island was originally built for trade monitoring, its function became obsolete over time, and for a while, Dejima even disappeared from the map.

In 2017, Dejima was fully restored, and today it is a must-visit tourist attraction in Nagasaki. Visitors can explore reconstructed buildings and experience what life was like during Japan's isolation era. A walk through Dejima truly feels like a journey back in time to historic Nagasaki.

2. Dejima Omotemon Bridge

The Dejima Omotemon Bridge is a bridge that connects the reconstructed artificial island of Dejima with the city of Nagasaki, gracefully spanning over the water. Although the original bridge was dismantled during the Meiji era, it was faithfully restored in 2017 as part of the Dejima restoration project—right in the same spot where the original once stood. Today, it serves as the main entrance for tourists visiting Dejima. Walking across this bridge, which stands in the exact location as it did during Japan's era of national isolation (sakoku), offers visitors the thrilling sensation of stepping back in time. It's a must-visit historical attraction in Nagasaki that blends heritage with immersive experience.

3. Former Dejima Seminary

The Former Dejima Seminary is the oldest surviving Protestant Christian seminary in Japan. During the late Meiji period, the building was repurposed as a hospital, and today it serves as part of the Dejima Museum. Its charming retro sky-blue exterior makes it a popular photo spot for visitors. Guests are welcome to step inside the building, where the first floor features a gift shop and a relaxing rest area.

4. Former Stone Warehouse (Archaeological Museum)

The Stone Warehouse, as the name suggests, is a warehouse built of stone. The Former Stone Warehouse dates back to the end of the Edo period, when it housed Japan’s first Prussian trading company (Prussia covered areas of present-day northern Poland and Lithuania). It even conducted trade with the Kaientai, an organization led by the famous Sakamoto Ryoma. Today, this historic building functions as an archaeological museum, faithfully restored in its original stone architecture. On the first floor, visitors can view artifacts excavated from Dejima, while the second floor showcases the restoration techniques and reconstruction process of Dejima itself—making it a must-visit spot for those interested in Japanese history and archaeology.

5. Hai Rei Hissha Orandajin Heya (Dutch Scholars’ Quarters)

Located near the Dejima Front Gate Bridge, the Hai Rei Hissha Orandajin Heya (Dutch Scholars’ Quarters) once served as the residence of the chief clerk of the Dutch Trading Post in Dejima. Today, it functions as a museum dedicated to introducing and showcasing Rangaku (Dutch Studies), which was brought into Japan through Dejima during the Edo period. Visitors can view valuable historical artifacts from that era. The traditional Japanese-style brown building with its eye-catching bright blue handrails stands out as a distinctive and picturesque landmark in the area.

6. Second Storehouse (Niban-gura)

In the historical Dejima area, there were three storehouses lined up, named the First, Second, and Third Storehouses. The Second Storehouse, or Niban-gura, was primarily used to store imported dyes during the Edo period. Today, it serves as an exhibition space showcasing various trade goods that passed through Dejima.

The First Storehouse (Ichiban-gura) features scale models that depict the restoration work of Dejima, while the Third Storehouse (Sanban-gura) presents a recreated scene of how imported goods were once stored. Visiting all three storehouses offers a deeper understanding of the historical trade activities and daily life during Japan’s period of international exchange.

7. Former Nagasaki International Club

The Former Nagasaki International Club is a charming Western-style building with lime green pillars and window frames that give it a modern touch. Today, it operates as a restaurant where visitors can enjoy famous Nagasaki dishes such as Turkish Rice (Toruko Raisu), Nagasaki Champon, and Milkshake (Mirukuseki). Offering a wide variety of both savory meals and sweet treats, the restaurant lets you savor delicious food in a historic setting filled with nostalgia.

8. Nagasaki Dejima Wharf

Nagasaki Dejima Wharf is a vibrant commercial complex located in the bay area near Nagasaki Port. If you’re planning to visit the historic Dejima, this is a perfect spot to drop by afterward.
