Inside the main gate of Odawara Castle’s inner bailey stands a museum where visitors can experience samurai culture firsthand.
Along with armor displays and projection mapping, the museum even offers a costume dress-up experience in which you can wear samurai armor yourself. It’s a place where you can see, feel, and become part of the samurai world.
This article introduces the highlights and how to enjoy the Tokiwagi Gate SAMURAI Museum.
The Tokiwagi Gate SAMURAI Museum (Tokiwagi-mon SAMURAI-kan) is a samurai culture exhibit located within Odawara Castle Park in Odawara City, Kanagawa Prefecture. Situated on the second floor of Tokiwagi Gate — the main gate of the castle’s honmaru (inner bailey) — it is known for its samurai armor collection and projection mapping display.

The SAMURAI Museum displays samurai armor (kacchū) from various eras and styles.
Samurai armor was more than mere protection; it conveyed the status of the warlord who wore it and the dignity of the house he served. The crest (tatemono) atop the helmet, the shaping of the cuirass, and the color of the lacing cord (odoshi-ito) all reflected the individual taste and aesthetic sensibility of each warlord.
Among the exhibits, one piece stands out: a helmet bearing a large golden crescent moon crest.
Such crests served to announce the wearer’s presence on the battlefield, with designs reflecting each warlord’s convictions and prayers. Seeing them up close reveals intricate ornamentation and material textures that photographs simply cannot capture.
Where weapons once lay stored, warrior gear now stands displayed as works of art.
The armor that once guarded the lives and dignity of samurai has shifted its role with the passage of time, yet its spirit remains unchanged — something visitors can still feel today.
Another highlight is the projection mapping display, “Hana Utsu Yoroi.”
The performance features an innovative technique in which video imagery is projected directly onto armor set at the back of the exhibition room. By layering visuals not only on a screen but on the armor itself, the armor remains the true star of the show. Bathed in light and music, it transforms one scene after another — as though replaying the memories of its former owner.

This visual experience — unfolding over several minutes inside the quiet exhibition room — introduces viewers to the samurai worldview from an angle entirely different from simply viewing static armor.
At the SAMURAI Museum, visitors can take part in a dress-up experience to become a ninja, warrior, or princess.
Costumes come in both adult and child sizes, making this a popular experience among international visitors as well. After dressing up, you can step outside Tokiwagi Gate and take commemorative photos with Odawara Castle’s keep in the background. (Lockers inside the museum are available for storing belongings.)

Tokiwagi Gate (Tokiwagi-mon), which houses the SAMURAI Museum, is the main gate leading to Odawara Castle’s inner bailey (honmaru). Since the gate protecting the inner bailey was the most vital point of defense, Tokiwagi Gate was built larger and sturdier than any other structure within the castle.
Its construction uses a masugata-mon style (a box-shaped gate design that forces enemies to make sharp turns, slowing their advance and making them vulnerable to attack from above). The structure combines a tamon-yagura (connecting turret) with a watari-yagura (bridging turret), and the inside of the tamon-yagura once served as a storehouse for weapons and ammunition.
The gate takes its name from the pine trees planted beside it. “Tokiwagi” refers to evergreen trees. Just as pines keep their green leaves through winter and stay green for decades, the name carries the hope that Odawara Castle would prosper for generations to come.
Tokiwagi Gate once collapsed in the great earthquake of 1703 (Genroku 16), but was rebuilt in masugata-mon style in 1706 (Hōei 3), serving as the main gate of the inner bailey until the castle was abolished in 1870 (Meiji 3). The gate standing today was reconstructed in 1971 (Shōwa 46).
Within the turret of this very gate lies the SAMURAI Museum.
The Tokiwagi Gate that once stored weapons now stands as a museum preserving samurai culture. From the weighty craftsmanship of the armor, to the warrior spirit summoned through projection mapping, to the dress-up experience that lets you step into a samurai’s shoes — the world of the samurai is distilled within this small castle gate.
Here you’ll find a dense, armor-focused space quite distinct from the grand displays of the castle keep. Study the unique design of each suit of armor at your own pace, immerse yourself in the projection mapping, or slip into armor for a memorable photo.
Since castle keep admission tickets grant free entry, be sure to step through Tokiwagi Gate during your visit to Odawara Castle. Inside the gate, the world of the samurai awaits in quiet splendor.
