Jōtō-ku, Osaka
Jōtō-ku (城東区, Jōtō-ku) is one of the 24 wards of Osaka, Japan. "Jōtō" literally means "east of the castle", referring to Osaka Castle. It was separated from Higashinari and Asahi in 1943, and eastern Jōtō 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, Bunkyō and Taitō. In recent years, the construction of high-rise condominiums in the western and northern areas of Jōtō-ku has contributed to a steady population increase.
