History

SPORTS BULL CO., LTD. was founded in May 2015 in Tokyo, Japan. The company was established to build sports media and sports-experience businesses around the concept of "watch, play, support" (みる・する・ささえる). Its flagship product, the internet sports media platform SPORTS BULL, was developed to distribute news, live streams, highlight videos and original programming across a wide range of sports, including professional, amateur and student athletics. A key early development was the collaboration with KDDI Corporation. SPORTS BULL is operated as a collaboration business backed by KDDI, using the telecommunications company's technology to create new sports experiences. This relationship is reflected in the shareholder structure, which includes the KDDI Open Innovation Fund. Other shareholders include major Japanese media and entertainment companies such as Dentsu, The Asahi Shimbun Company, Hakuhodo, MIXI, ABC Frontier Holdings and Kodansha, as well as KSK Angel Fund LLC. Over time, the company expanded beyond its core media platform into five additional businesses. ANYTEAM was launched as a community service for middle-school, high-school and university club teams, allowing fans to interact, donate and crowdfund. BUKATSU ONE was created as a one-stop digital-transformation solution for municipalities implementing the regional devolution of school club activities, a policy promoted by Japan's Ministry of Education, Culture, Sports, Science and Technology and the Japan Sports Agency. COMIC BULL was established as an original sports manga project co-produced with Kodansha, available through the SPORTS BULL app. CORPORATE LEAGUE was launched as an inter-company sports league for businesspeople, with its first sport being the four-a-side football format "4v4" devised by Keisuke Honda; it is operated as a joint project of Now Do, Undo Tsushinsha and Persol Innovation. dodaSPORTS was created as a sports career media business linked with the job-change service "doda," using SPORTS BULL's media platform and production know-how to reach a broad sports fan audience and connect them with career opportunities in the sports industry. The company has also undertaken large-scale live-streaming initiatives. Through the "Virtual Koshien" service within SPORTS BULL, it has provided free live streaming of all games of the National High School Baseball Championship, including regional tournaments, supported by au. It has also published research on the costs of school club activities, highlighting the financial burden on families. As of its corporate disclosures, SPORTS BULL CO., LTD. remains a privately held company headquartered in Minato-ku, Tokyo, with capital of 410,344,000 yen. Its leadership team includes Representative Director, President and CEO Yusuke Wakamura, several directors and executive officers, Founder and CVO Kojiro Kurotobi, CTO Shohei Saito, and outside directors from Global Brain and Dentsu.
