Nagakute Historical Museum, Local museum in Nagakute, Japan

The Nagakute Historical Museum occupied a building inside Kosenjo Park, on the site of the 1584 Battle of Komaki and Nagakute. Its ground floor held a terrain model of the battle area and a replica of a battle-screen painting; the upper floor displayed finds from city excavations, armour, battle gear, everyday tools, documents on the local bo-no-te stick fighting and festivals, and lignite from Nagakute. A glass artwork depicting the Battle of Waterloo, shown at the 2005 Aichi Expo's Nagakute venue, was moved here. The museum closed on 30 November 2025.

The museum was founded in 1985 and has collected objects and records documenting the region's history ever since. Over the years it has built an archive that reflects different phases of local development.

The museum's name comes from the town, and its second floor held artefacts from excavations in Nagakute along with documents on the local bo-no-te stick fighting and festivals. Armour, battle gear and tools of daily food, clothing and shelter were displayed, plus lignite and Nagakute. A glass artwork depicting the Battle of Waterloo, shown at the Nagakute venue during Expo 2005, was moved here.

The museum closed permanently on 30 November 2025, so it can no longer be visited; its collection on the Battle of Komaki and Nagakute is now held at the Nagakute Kosenjo Memorial Hall, which opened on 22 April 2026. The site stood inside Kosenjo Park, about 250 m north of the Kosenjo-minami intersection on Route 6, roughly 2 km east of the Nagoya IC; the park's car park has 49 spaces. The nearest station is Linimo's Nagakute Kosenjo, also served by the N-bus Chuo loop and Meitetsu buses from Fujigaoka.

The museum closed permanently on 30 November 2025. Its collection on the Battle of Komaki and Nagakute was transferred to the Nagakute Kosenjo Memorial Hall, which opened on 22 April 2026. A glass artwork depicting the Battle of Waterloo, moved here from the Nagakute Hiroba venue of Expo 2005, was among the exhibits.
