Odawara Castle
The seat of the Hojo, once ringed by a nine-kilometre earthwork enclosing the whole town, now a park with a rebuilt keep.
Updated 20 October 2026
Odawara was the base of the Later Hojo, who held much of eastern Japan through the sixteenth century, and the castle was among the strongest in the country - not for its keep but for the sokogamae, an earthwork and moat line of about nine kilometres that enclosed the entire town, one of the earliest examples of that approach in Japan. Sections of the bank survive in the streets around the modern park and are marked. The castle was dismantled in the Meiji period; the present keep is a 1960 reinforced concrete reconstruction, rebuilt to the eighteenth-century plans, with a museum inside and a view from the top over the town to Sagami Bay. The Tokaido road passed here, and the castle's function was to control that route into the Kanto plain. Cherry trees fill the grounds in April.
History
Odawara was a stronghold of the Doi clan in the Kamakura period, and in 1495 it passed from the Omori clan to Ise Moritoki of Izu, founder of the Odawara Hōjō, whose family held it for five generations. The old keep was torn down in 1870 to 1872, and the present one was built in reinforced concrete in 1960 on its stone base (Wikipedia, Odawara Castle).
Highlights
- The sokogamae - traces of a nine-kilometre earthwork that once enclosed the whole town.
- A 1960 keep - reconstructed to eighteenth-century plans, housing a museum.
- The Tokaido position - a castle sited to control the road into the Kanto plain.
- Cherry in the grounds - the park filling with blossom in April.
When to go
April for cherry. Two hours. It is an easy stop on the Tokaido shinkansen line.
What to expect
The keep is concrete with a modern interior and lift. The great earthwork survives only in fragments among houses. It is a park with a castle rather than a preserved fortress. Blossom season is crowded.
Nearby
Hakone is west up the valley; Kamakura is north-east along the coast.
