This park spreads across Utsubo Honmachi, an office district in Osaka. It is long and narrow, measuring 800m east to west and 150m north to south, with a total area of 9.7ha. It is divided into the East Garden and the West Garden by the Naniwa-suji street that runs north to south through the center. The East Garden has the city's oldest rose garden, the Utsubo Tennis Court with 10 tennis courts, and a row of zelkova trees that changes color with the seasons, while the West Garden has the Utsubo Tennis Center with 16 tennis courts that is used for international competitions. During Hideyoshi's time, the surrounding area flourished as the Zakoba Fish Market and a salted and dried fish wholesale district. Hearing fish merchants selling fish in the town with spirited shouts of "cheap, cheap," Hideyoshi remarked that "yasu (arrow nest) means yasu (a tool for putting arrows in)," and the town was named after the phrase. Kyomachibori, on the north side of the park, is home to many stylish cafes and general stores.
