Absolutely worth visiting if you’re in Odawara. I’d recommend getting the combination ticket for Odawara Castle and the Samurai Museum. It was around ¥1,000 when I visited, basically the same price as buying the castle ticket separately, so the combo ticket is definitely worth it.
The Samurai Museum was surprisingly fun. There are lots of samurai armor, swords, weapons, and other historical displays, and the exhibits are very well presented. Even if you’re mainly coming for the castle, I wouldn’t skip it.
Odawara Castle itself has been beautifully reconstructed and is very comfortable to explore. There’s air conditioning throughout the interior, which was amazing on a hot summer day. The museum inside covers the history of Odawara and the Hojo clan in a lot of detail, so it feels like an actual historical museum rather than just an empty reconstructed castle. Once you reach the top, you get a great panoramic view over Odawara and Sagami Bay.
The area around the castle is also worth walking around. There are several old castle gates and historic structures nearby. Some parts have obviously been restored for preservation, but you can still see a lot of the original character. There are also huge old trees throughout the grounds, and the moat surrounding the castle makes the whole area especially scenic and peaceful.
Overall, Odawara Castle is much more interesting than I expected. The combination of the castle, Samurai Museum, detailed history, old gates, moat, ancient trees, and the ocean view from the top makes it very easy to spend a few hours here. Definitely one of my favorite historical spots in the area.

I came here in summer, luckily it was a bit cloudy and not that hot. The walk to the main entrance (via Umadashimon, on Ohoribata-dori), which is highly recommended for starting the castle grounds tour, is a bit farther from the train station. There are guided arrows and signs to get there. I exited the place via the North Gate (Oshiro-dori). There is a Ninja museum and a Samurai museum on the castle grounds. I mainly focused my tour on those, and the main castle. The entrance fee for the adults is ¥1000. This includes the tour inside the castle, as well as the Samurai museum. There are no elevators. The inside of the castle has been modernized, after its reconstruction, basically more of a modernized museum, rather than preserved parts of the original structure. Still, the history of it all is meaningful and interesting. It is also air conditioned. There are spacious lockers, after passing the ticketing entrance, if needed. Overall a lovely experience.
Did Odawara Castle as a quick stop on the way out to Hakone and honestly it ended up being one of the highlights of the trip. Way more to it than I expected.
The castle itself is gorgeous. Reconstructed donjon, sure, but it looks the part from every angle and the grounds around it are seriously well kept. Walking up through the main gate area, the whole approach builds the experience the right way.
Inside the keep is a legit museum. Armor, swords, banners, scrolls, old maps of the region, and tons of context about the Hojo clan and the famous 1590 siege. Even if you're not a history buff you'll get pulled in. The view from the top floor is the payoff — you can see all the way to the coast and on a clear day right up into the Hakone mountains.
The park grounds are worth the wander on their own. We caught it right around cherry blossom season and it was unreal — pink everywhere, families picnicking, locals just enjoying the day. There's also samurai/ninja stuff for kids, and it's all done really well.
Walkable from the station and easy to fit into a half day. Absolutely go.
Absolutely loved visiting Odawara Castle. The architecture is stunning and the entire area feels peaceful and beautifully maintained. The red bridge, surrounding trees, and historic atmosphere made the experience unforgettable. Everything was clean, organized, and easy to explore. One of my favorite places during my Japan trip. Highly recommend visiting if you enjoy history, culture, and scenic views.🫶🏻✨
Odawara Castle may not receive as much attention as some of Japan’s more famous castles, but it is an underrated gem that is well worth visiting.
Although the castle tower wasn’t part of this visit, exploring the castle grounds and surrounding complex was rewarding in its own right. The traditional architecture, stone walls, gates, and beautifully maintained gardens create a peaceful setting that invites a slower pace.
Visited on a late autumn afternoon, the golden sunlight added a warm glow to the castle and surrounding maple trees, making the scenery especially picturesque. The seasonal colours and relaxed atmosphere made it a wonderful place for a leisurely walk and photography.
For those looking to experience a beautiful Japanese castle without the overwhelming crowds of some of the country’s more famous landmarks, Odawara Castle is an excellent choice. Even without entering the main keep, the grounds alone make the visit worthwhile.
