Chiba Port Tower is a tower located in Chiba Port Park, Chūō-ku, Chiba, Chiba Prefecture, Japan. It is 125.1 m tall and has four stories. It was built in 1986.
The tower opened on June 15, 1986. It was built in commemoration of the population of Chiba Prefecture exceeding five million in 1983. This is because the expansion of the commuter belt to Tokyo and the development of the Keiyō industrial zone had caused rapid growth in Chiba Prefecture’s population from 1970s to 1980s.
