Why Dejima Is Worth Adding to Your Nagasaki Family Itinerary
When we first told our kids we were visiting a tiny artificial island where Dutch merchants once lived in near-total isolation for over 200 years, they looked at us blankly. But the moment they stepped through the wooden gate at Dejima and spotted a staff member dressed in full 18th-century Dutch costume, suddenly history became very real indeed.
Dejima is one of those rare historical sites that genuinely works for school-age children. It is compact, interactive, and packed with just enough quirky details to keep curious minds engaged without requiring a university degree to appreciate. As expat parents living in Fukuoka, we have dragged our kids through plenty of museums where they spent most of the visit asking when we were leaving. Dejima was refreshingly different.
If you are planning a family trip to Nagasaki, make sure you read our The Ultimate Family-Friendly Guide to Nagasaki with Kids: History, Theme Parks & Hidden Gems for the full picture. But in this post, we are diving deep into Dejima specifically — what to expect, how long to spend there, and how to make it the highlight of your day.
A Quick History Your Kids Will Actually Find Interesting
Here is the version we told our children in the car on the way: Japan once decided it did not want foreigners around. For roughly 220 years during the Edo period, the country closed itself off from almost the entire world. Almost. The one exception was a small group of Dutch traders who were allowed to stay — but only on a tiny fan-shaped artificial island in Nagasaki harbour called Dejima, which measured just 120 metres by 75 metres. They could not leave. Japanese people could not enter without permission. And yet, through that tiny island, Japan kept a window open to the outside world.
Our older child immediately asked: “So they were basically in jail?” Which is not entirely wrong, and is exactly the kind of question that leads to a great conversation about trade, power, and how countries interact with each other.
The island you visit today is a carefully reconstructed version of what Dejima looked like at its peak in the late Edo period. Land reclamation over the centuries had merged the original island into the surrounding city, but from the 1990s onward, Nagasaki has been steadily rebuilding the historic structures. Today about 25 buildings have been reconstructed, and the project is ongoing.
Entry Fees and Opening Hours
One of the things we appreciate about Dejima is that it is genuinely affordable for families. Here is what to expect:
- Adults (18 and over): 520 yen
- High school students: 200 yen
- Junior high school students and younger: Free
That means a family with two adults and two primary school-age children pays just 1,040 yen total. For a solid hour or more of genuinely engaging history, that is exceptional value.
Dejima is open daily from 8:00 AM to 9:00 PM (last entry at 8:40 PM) during peak season, with slightly shorter hours at certain times of year. We recommend checking the official Dejima website before your visit, particularly around New Year and during special exhibition periods. The site is well staffed and signage is available in English, which is a relief when you are trying to explain exhibits to curious kids without squinting at kanji.
What Kids Love: The Interactive Exhibits
Dejima has done a thoughtful job of making history tactile. Rather than just reading panels, children can actually engage with many of the exhibits. Here are the highlights that worked best for our family:
The Reconstructed Merchant Houses
The buildings themselves are the main attraction. Walking through the Chief Merchant’s residence, the warehouses, and the guest rooms gives children a genuine sense of scale and daily life. Everything feels lived-in rather than sterile. Our kids spent a long time examining the Dutch furniture, the trading ledgers on display, and the personal belongings of merchants who had not seen their families back in the Netherlands for years at a time.
Period Costumes for Kids
This was the unexpected highlight of our visit. At certain points in the site, children (and willing adults) can try on replica period costumes — both Dutch merchant clothing and Japanese attire from the Edo period. Our youngest was absolutely thrilled. There is something about putting on a costume that transforms a museum visit into something more like play, and the photo opportunities are genuinely charming. Staff are helpful and patient, even with the wiggly ones.
Interactive Trade Displays
Several exhibits explain what goods were traded through Dejima — Dutch imports like clocks, telescopes, and medicine alongside Japanese exports including ceramics, lacquerware, and copper. There are hands-on elements where children can examine replica objects and understand why these items were so valuable. Our older child was particularly fascinated by the early scientific instruments, which sparked a long conversation about how knowledge of Western science quietly filtered into Japan through this single tiny island.
The Scale Model
Near the entrance, there is a detailed scale model of Dejima at its historical peak that children find endlessly fascinating. Seeing the island in miniature helps them understand the layout before exploring the real thing, and it makes for great “treasure map” energy if your kids enjoy that kind of orientation.
Practical Tips for Visiting with Young Children
Dejima is stroller-friendly for the most part, though some of the reconstructed buildings have traditional wooden steps that you will need to navigate. The site is compact enough that even easily-tired toddlers can manage the whole thing on foot. Here are a few things worth knowing before you go:
- Timing: We arrived around 10:00 AM on a weekday and had the place largely to ourselves for the first hour. Weekends and school holidays are busier, particularly with Japanese school groups.
- Allow 60–90 minutes: This is not a full-day destination, which is actually a strength. It fits beautifully as part of a longer Nagasaki day rather than requiring a dedicated visit.
- English support: English audio guides are available for rent, and many of the display panels include English text. Staff at the main buildings often speak some English and are happy to assist.
- Restrooms: Clean and accessible facilities are available within the site.
- Food: There is no dedicated dining inside Dejima, but the surrounding Nagasaki waterfront area has plenty of cafes and restaurants a short walk away.
Combining Dejima with Nagasaki Chinatown
This is the combination we recommend without hesitation. Nagasaki Chinatown (Shinchi Chinatown) is a 10–15 minute walk from Dejima, making it the ideal follow-up for hungry families. It is the oldest Chinatown in Japan, and while it is compact, the energy is lively and the food is excellent.
Nagasaki champon — a rich, milky noodle soup loaded with seafood and vegetables — is the dish to order, and children tend to love it. Sara udon, crispy noodles with a similar topping, is another local favourite. The restaurants around Chinatown are generally family-friendly and accustomed to international visitors.
The historical connection between Chinatown and Dejima is worth mentioning to older children: during Japan’s period of isolation, Chinese traders were also permitted in Nagasaki, though they were confined to a designated settlement. The multicultural history of Nagasaki runs very deep, and this combination visit helps children understand just how unusual this city was in the context of Edo-period Japan.
Getting to Dejima
Dejima is centrally located in Nagasaki city and easy to reach by public transport. The Nagasaki tram system is the most convenient option, with a stop (Dejima Station) directly adjacent to the site. If you are navigating Nagasaki’s public transport for the first time, our guide to Riding the Nagasaki Trams with a Stroller: Routes & Tips has everything you need to know about fares, routes, and managing the trams with young children and buggies.
If you are driving from Fukuoka or elsewhere in Kyushu and wondering whether to hire a car or rely on trains, our article on Getting Around Kyushu with Kids: Car vs Train for Family Travel breaks down the decision in detail. For Nagasaki city itself, we find public transport generally easier than trying to park, particularly around the waterfront area.
Nagasaki also fits naturally into a broader Kyushu family trip. If you are still in the planning stages, our 7-Day Kyushu Family Itinerary: Fukuoka, Beppu, and Kumamoto by Train gives a solid framework you can adapt to include Nagasaki as an extension or swap.
Is Dejima Right for Your Family?
We would say Dejima works best for children aged 6 and up. Younger children will enjoy the costumes and the open spaces, but much of the context will go over their heads. School-age children who have some awareness of Japanese history — or who are studying it — will get the most out of it. Teenagers who are into history, trade, or the kind of “what if” thinking that alternate history encourages will also find it genuinely compelling.
For families visiting Kyushu more broadly, Dejima slots in beautifully as part of a day in Nagasaki alongside Glover Garden, the Peace Park, or the Nagasaki Museum of History and Culture. The city rewards slow exploration, and Dejima is a strong anchor for the historical part of your day.

Frequently Asked Questions
How long should we spend at Dejima with kids?
Most families with school-age children will find 60–90 minutes is plenty. The site is compact, which means you can cover everything without rushing or dealing with overtired legs. If your children are particularly engaged with the interactive exhibits or costume opportunities, you might stretch it to two hours, but it is not a full-day destination. Plan it as part of a wider Nagasaki day for the best experience.
Is Dejima free for young children?
Yes. Children of junior high school age and younger (approximately 14 and under) enter free of charge. High school students pay 200 yen, and adults pay 520 yen. This makes Dejima one of the more affordable historical attractions in Kyushu for families.
Can you use a stroller at Dejima?
The outdoor pathways are stroller-accessible, but many of the reconstructed buildings have traditional raised wooden entrances with steps. You may need to leave your stroller outside individual buildings and carry younger children inside. The site is compact enough that this is manageable, and staff are helpful if you need assistance.
What is the best way to combine Dejima with other Nagasaki attractions?
Dejima pairs particularly well with Nagasaki Chinatown (a 10–15 minute walk) for lunch. For a fuller day, you could add Glover Garden in the afternoon, which offers beautiful views over the harbour and has its own historical connections to the late Edo and Meiji periods. Nagasaki’s tram network makes it easy to move between these sites without needing a car, and a single-day tram pass offers good value if you plan to make multiple stops.
