The original castle was the impenetrable seat of the Odawara Hojo clan, successfully resisting Toyotomi Hideyoshi's siege for several months in 1590.
The 1960 reconstruction was based on Edo-period architectural models and photos of the original keep.
Odawara Castle Park is officially recognized as one of the best locations in Japan for cherry blossoms, with over 300 Somei Yoshino trees.
The castle’s stone walls were constructed using a unique technique that remains largely intact despite the region's high seismic activity.
Historical records indicate that the original Edo-period tower collapsed during the Great Kanto Earthquake of 1923.
The current museum display includes an authentic 'tachi' sword and various artifacts excavated from the castle grounds.
During the Sengoku period, the castle was considered one of the largest and most strategically defended fortresses in the Kanto region.
Odawara Castle is a prominent Japanese castle reconstruction serving as a hub for local history and Hojo clan heritage. The current main keep is a reinforced concrete reconstruction completed in 1960 that replicates the external appearance of the Edo-period structure. The interior functions as a multi-story museum featuring samurai armor, swords, and historical documents related to the Odawara Hojo. Visitors can access an observation deck at the top of the keep providing panoramic views of Sagami Bay and the surrounding Hakone mountains. The castle grounds are part of Odawara Castle Park, which encompasses historical stone walls, moats, and relocated gates. The site is widely recognized as one of Japan's Top 100 Castles and a major destination for cherry blossom viewing in spring. The grounds also host a small zoo and amusement park area, though these are separate from the main historical keep exhibits.

Wear comfortable, slip-on shoes as you will be frequently removing them to enter different sections of the museum.
Visit the 'Tokiwagi-mon' Gate, which houses a separate exhibition of samurai weaponry, often overlooked by visitors focusing solely on the main keep.
Check the weather forecast before your visit; the view from the top floor observation deck is significantly obstructed on rainy or foggy days.
Do not mistake the smaller, secondary buildings for the main museum; ensure you visit the central keep for the primary collection.
Occasionally closed for maintenance in early December; check official site for rare irregular closures.
Refrain from using flash photography inside the museum displays; remain quiet within the main keep.
