Odawara Castle is a prominent flatland-mountain castle (hirayama-jiro) located in Odawara City, Kanagawa Prefecture. It served as the strategic headquarters for the Hojo clan during the Sengoku (Warring States) period and remains a vital symbol of Japanese history. Today, it is a designated national historic site and a beautifully maintained castle park where visitors can enjoy both historical ruins and the natural surrounding environment.
The site holds immense historical significance as the seat of power for the Hojo clan during the Sengenseki era. Later, during the Edo period, it served as the administrative center for the Odawara Domain. The castle ruins are protected as a national historic site, serving as an essential educational resource for understanding Japanese castle architecture, defensive systems, and the political shifts of the era.

The architectural structure of the castle, the majestic main keep (tenshukaku), and the various facilities within the castle park are the primary attractions. Beyond the keep, the site features specialized facilities such as the SAMURAI Museum and the NINJA Museum, which offer immersive cultural experiences. Visitors can also explore the remnants of ancient defensive systems, including historical gates and bridges that define the unique character of this fortification.
The Odawara Castle Park offers a different charm depending on the season. The spring months (March to May) and the autumn season (September to November) are particularly beautiful, as the changing colors of the foliage complement the historic stone walls and structures. Visiting during daylight hours is highly recommended to fully appreciate the panoramic views from the top of the keep and the intricate details of the surrounding fortifications.

Visitors can climb the main keep to experience the view or enjoy a leisurely stroll through the expansive castle park. To deepen your understanding of Japanese history, the site offers specialized exhibits at the SAMURAI and NINJA museums. Additionally, the use of the official digital guide app and video content allows for a more profound exploration of the castle's structural-history and defensive mechanisms.
Odawara Castle Park is a central pillar of the Odawara sightseeing route. The park is dotted with various historical landmarks, such as gates and bridges named after significant historical events or figures. Walking through these areas allows visitors to grasp the spatial layout and the strategic importance of the castle's original design.

As the castle grounds and park are quite extensive, we highly recommend wearing comfortable walking shoes. It is advisable to check official information regarding facility access before your visit. For groups of 30 or more, advanced reservations via phone or the official web form are mandatory. For groups of fewer than 30 people, tickets can be purchased directly at the ticket office on the day of your visit.
