is one of the 24 wards of Osaka, Japan. "Jà Âtà Â" literally means "east of the castle", referring to Osaka Castle. It was separated from Higashinari and Asahi in 1943, and eastern Jà Âtà  became Tsurumi in 1974.
As of 2025, the population density is the second largest of a city-designated municipality in Japan, after Nishi Ward. Additionally, when the special wards of Tokyo are also included, it is the eighth densest ward overall after Toshima, Nakano, Sumida, Arakawa, Bunkyà  and Taità Â. In recent years, the construction of high-rise condominiums in the western and northern areas of Jà Âtà Â-ku has contributed to a steady population increase.
