屋上遊園地

Urban Farm DB summary

Japanese department store rooftop amusement parks trace back to Nihonbashi Mitsukoshi's 'aerial garden' in 1907, with Japan's first permanent rooftop amusement park, 'Sportsland,' opening at Matsuya Asakusa in November 1931. They peaked from the mid-1950s through the late 1960s, but declined after department store fires in 1972 and 1973 led to a revised Fire Service Act requiring half of rooftops to be kept as evacuation areas; as of 2023, only five stores—Matsuzakaya Takatsuki, Matsuzakaya Nagoya, Daiwa Korinbo, Iyotetsu Takashimaya, and Hamaya Department Store—still operate one.
