Ichihara Lakeside Museum, Art museum at Lake Takataki, Ichihara, Japan.

The Ichihara Lakeside Museum stands on the shore of Lake Takataki in Chiba Prefecture. It opened under this name on 3 August 2013, when the earlier Ichihara City Water and Sculpture Hill, operating since 1 November 1995, was renovated and reopened under a designated administrator chaired by Fram Kitagawa. The museum is the central venue of the Ichihara Art x Mix triennial, and its lakeside setting has drawn television drama and music video shoots.

The museum opened in 2013 as part of Ichihara city's 50th anniversary celebrations, redesigning a previous cultural facility that had operated since 1995. This transformation marked a shift toward presenting contemporary art in the region.

The collection showcases work by Yukio Fukazawa, an artist famous for copperplate art, along with rotating shows of contemporary creations from Japanese and international artists. These selections show how this place has become a center for artistic practice and expression in the area.

The museum is open weekdays from 10:00 to 17:00, weekends and holidays from 9:30, with later closing on Saturdays and days before holidays. It closes on Mondays, or the next weekday when Monday is a holiday, and over the New Year period. Admission is 200 yen for adults, 100 yen for high school and university students and those aged 65 and over, and free for junior high school students and younger and for holders of a disability certificate.

The museum is the main venue of Ichihara Art x Mix, an art festival held every three years. Its galleries and lakeside grounds have also served as filming locations for Japanese television dramas and music videos, including the Netflix series First Love.
