Marune Fort was one of several forts built around Odaka Castle to contain the Imagawa. In particular it blocks the road to Kutsukake Castle. Matsudaira Motoyasu (Tokugawa Ieyasu) defeated Marune Fort and Washizu Fort with overwhelming forces at the Battle of Okehazama. Some people say Motoyasu first came to prominence as a battle tactician because of this battle.

Visit Notes

Compared to some of the other forts in the area, this seems to have been a more well developed fortification. While there are few ruins to be seen, the grouns of this round hilltop have not been developed over so it makes a worthwhile visit along with Odaka Castle and Washizu Fort.

Marune-toride is an earthworks fort ruin in the Ôdaka neighbourhood of Midori Ward, Nagoya City. I came here after visiting Washizu-toride. I liked this site more. There is clear terracing in a belt-like fashion beneath the top of the hill, which does impress one as an obikuruwa (belt bailey). There is a marker for the castle at the top of the hill where presumably the main bailey was. Toward the rear of the site there are what look like some earthworks which could’ve constituted a horikiri (trench) complex, but it’s hard to be sure as a road passes through there now.
