Yomiuriland よみうりランド
It opened in 1964, and the park stretches across two prefectures at once.
It opened on 19 March 1964 as ‘Yomiuri Land’, with the name written differently from today; in 1968 it took its current spelling. ⚠️ It extends ‘across Inagi, Tokyo, and Kawasaki, Kanagawa’ (「東京都稲城市及び神奈川県川崎市にまたがる」): the main entrance and the address fall in Inagi, which is within Tokyo, but part of the grounds spills over into another prefecture.
