The Keitakuen garden is a pure Japanese style fixture of the Tennoji park grounds, donated to the city of Osaka by the merchant Sumimoto family in the year Taisho 15 (1926). The garden is bright, spacious, and modern, allowing visitors to freely appreciate the surrounding nature. Free entry for junior high school students currently residing and attending school in Osaka-shi (and the surrounding area). The Chosei-an tea room located within can be used for rendezvous over tea, in addition to commemorative photos.

慶沢園是位於天王寺公園內的純日本風庭園。大正15年（1926），江戶時代時由富商・住友家贈送給大阪市。近代已對外開放，是個可以散心且自然景觀豐富的庭園。住在大阪市内・就學及大阪市立（包含市外）的學校就學的國中，國小生免費。另外，慶沢園裡有讓人放鬆的茶室「長生庵」、常用來做品茶會，拍照紀念等。
