Nezu Memorial Museum, Biographical museum in Yamanashi, Japan.

The Nezu Memorial Museum opened in 2008 in Yamanashi, preserving the former Nezu family residence. Its grounds of about 6,700 m² hold a nagayamon gate facing the old Ome Kaido, a main house completed in 1933, and a rare three-storey earthen storehouse 10.365 m tall. A garden with Mount Fuji and the Misaka Mountains as borrowed scenery is watered by a stream where fireflies fly in summer.

The Nezu family donated the house and grounds to Yamanashi City in 2003, and the museum opened in October 2008. The main house was completed in 1933 with concrete foundations, a boiler, indoor fire hydrants and concealed wiring. The Nagayamon gate and the three-storey storehouse, 10.365 m tall, were registered as national Tangible Cultural Properties on 5 December 2007.

The museum occupies the former Nezu family home, donated to Yamanashi City in 2003 by descendants of Kaichiro Nezu, the railway magnate. Its Nagayamon gate, once facing the old Ome Kaido, now serves as the entrance, and a ditch with irises runs along the street boundary. The garden borrows Mount Fuji and the Misaka range as scenery, and fireflies fly over its stream in summer.

The site is accessible from the nearby train station and offers a calm visit through its galleries. Plan adequate time to explore the collections at a comfortable pace.

The property preserves several traditional structures including a Nagayamon gate and a historic storehouse. These buildings stand as examples of the craftsmanship and architectural style from an earlier era.
