Tamateyama Park, Urban park in Kashiwara, Osaka, Japan

Tamateyama Park is a municipal park opened in March 1999 on the Tamateyama hills in Kashiwara, Osaka Prefecture, on the site of the former Kintetsu Tamateyama amusement park. Its 68,000-square-metre grounds, mostly owned by the temple Anpukuji and leased by the city, hold kofun burial mounds near the east entrance, a warehouse-like toy and history museum, and a gazebo from 1908.

The hill, formerly called Komatsuyama, was the site of the Battle of Dōmyōji in the 1615 summer campaign of Osaka, where the Toyotomi commander Gotō Mototsugu (Matabei) encamped and died fighting the Tokugawa forces. A memorial tower for the dead of both armies, a monument to Gotō Matabei and a weeping cherry named after him stand in the park. The park itself opened in March 1999 on the grounds of the former Kintetsu Tamateyama amusement park, which the Kintetsu railway company had opened in 1908.

The hill's old name, Komatsuyama, appears in accounts of the 1615 Battle of Dōmyōji, where Gotō Matabei died; a memorial tower for both armies' dead, his monument and a weeping cherry named after him stand in the park. A stone inscribed with a haiku by Kobayashi Issa, who visited in 1795, is also here.

The park is open from 9 a.m. to 5 p.m. and is closed on Wednesdays. It is about a 15-minute walk from Dōmyōji Station on the Kintetsu Minami-Osaka Line, or about 20 minutes from Kawachi-Kokubu Station on the Kintetsu Osaka Line. The grounds lie on the Tamateyama hills, with the kofun cluster near the east entrance.

The park keeps a relic of its amusement-park past: a warehouse-style Toy and History Museum displays documents from the former Kandai Railway amusement park and the door of a dismantled Ferris wheel. The park's gazebo, called the Antique Music Hall, dates from the 1908 opening and still bears the railway company's seal at its top.
