Tokyo Dome Corporation

Tokyo Dome Corporation (株式会社東京ドーム) is a Japanese leisure, sports, and entertainment company best known as the operator of Tokyo Dome, Japan's first all-weather multipurpose stadium, and the surrounding Tokyo Dome City complex in Bunkyo, Tokyo. The company traces its origins to 1936, when it was founded as Korakuen Stadium Co., Ltd. (株式会社後楽園スタヂアム) to build and manage a new baseball stadium for the emerging professional teams of the era, including the Tokyo Giants. Its Korakuen Stadium opened in 1937 and served as a major venue for baseball, sumo, circus, and other entertainment until it closed in 1987 to make way for the domed stadium. Over the decades the company diversified into a broad leisure and entertainment business. It opened Korakuen Yuenchi (now Tokyo Dome City Attractions) in 1955, developed resort properties such as Atami Korakuen, operated bowling centers, ice rinks, and a cycling track, and expanded into retail with the Shop In chain. In 1988 the company opened Tokyo Dome, Japan's first fully covered multipurpose stadium, which became a landmark venue for baseball, concerts, and large-scale events. The company was listed on the Tokyo Stock Exchange in 1949 and remained publicly traded until 2021. In 2021, following a tender offer, Mitsui Fudosan acquired an 80% stake and Yomiuri Shimbun Group retained 20%, making Tokyo Dome Corporation a consolidated subsidiary of Mitsui Fudosan and ending its stock exchange listing. Today the company operates Tokyo Dome, Tokyo Dome City Attractions, the LaQua spa and commercial complex, Korakuen Hall, TeNQ (a space-themed museum), and various event and hospitality businesses. It also hosts and promotes concerts, dinner shows, seasonal events, and community activities, and has pursued sustainability initiatives such as renewable energy supply for Tokyo Dome City.

Tokyo Dome Corporation was founded on December 25, 1936, as Korakuen Stadium Co., Ltd. (株式会社後楽園スタヂアム), established to build and operate a new baseball stadium for the professional teams that were emerging in Japan, including the Tokyo Giants. On September 11, 1937, Korakuen Stadium opened and would remain in operation until 1987. In its early years the company also organized events such as the first All-Japan Invitational Ski Jump Tokyo Tournament in 1938 and, during the 1940s, a 40-day Kinoshita Circus that became one of its most popular wartime attractions. In 1942 it established Korakuen Real Estate, and in 1943 held the first Korakuen Grand Circus. In 1944 it hosted a Dai-Nippon Sumo tournament, and in 1946 opened a Go and Shogi parlor on the third floor of Korakuen Stadium, marking its entry into diversified management. In 1949 the company listed its shares on the Tokyo Stock Exchange (and on the Osaka Stock Exchange), and it opened the Korakuen Keirin velodrome. The 1950s saw further expansion into leisure: night-game lighting was installed at Korakuen Stadium in 1950, an ice skating rink called Ice Palace opened in 1951, a roller skating rink in 1954, and Korakuen Yuenchi (now Tokyo Dome City Attractions) opened in 1955. In 1959 it opened the Ishiuchi Korakuen Ski Resort and the following year the Ishiuchi Korakuen Country Club, beginning its resort business. During the 1960s it developed leisure facilities across Japan, including Atami Korakuen in 1965, and opened the Korakuen Bowling Center and Korakuen Bowling Hall in 1962. In 1969 it established Shinshōji Co., Ltd. The 1970s brought the first Hero Show in 1971, the opening of the first Shop In store in Shinjuku in 1971, the Yellow Building in 1973, and a giant pool at the stadium grounds in 1973. In 1976 Korakuen Stadium introduced Japan's first artificial turf for baseball. In 1977 the Yellow Building Annex opened. In the 1980s the company built Japan's first all-weather multipurpose stadium, Tokyo Dome, which opened in 1988. In 1981 an Aurora Vision screen was installed at Korakuen Stadium, and Korakuen Sports (now Tokyo Dome Sports) was established. In 1985 Korakuen General Service (now Tokyo Dome Facilities) was established, and in 1985 Osaka Korakuen was founded. Tokyo Dome opened in 1988, and the company continued to expand its urban entertainment complex, later branded Tokyo Dome City. The company remained listed on the Tokyo Stock Exchange from 1949 until 2021. In 2021, following a tender offer, Mitsui Fudosan acquired an 80% stake and Yomiuri Shimbun Group retained 20%, making Tokyo Dome Corporation a consolidated subsidiary of Mitsui Fudosan and ending its stock exchange listing. In recent years the company has continued to operate Tokyo Dome, Tokyo Dome City Attractions, LaQua, Korakuen Hall, and TeNQ, while hosting concerts, dinner shows, seasonal events, and pursuing sustainability initiatives such as renewable energy supply for Tokyo Dome City.
