Place in History - Junzo Hasegawa a player in Japanese pro-wrestling's glory days and in the years following Rikidozan's death he became a major power broker up until the collapse of JWA and the end of an era. As Yoshinosato, he was successful in sumo and rose to the class of Maegashira (four ranks under Yokozuna) before retiring in 1954 to pursue pro-wrestling. First, he was the Light Heavyweight champion, winning the tournament to establish the title. Eventually, he vacated the belt and captured the junior heavyweight title following a match with the company's #2, Michiaki Yoshimura. Yoshinosato was also half of the first All Japan Tag champions with Kokichi Endo. He was one of JWA's upper midcard talents and even enjoyed some success abroad as many Japanese workers did in the 60s. Then Rikidozan died and the pro-wrestling business in Japan was turned upside down. He became JWA's vice-president under Toyonobori, who was the company's top star and he was a key member in keeping the company going. In the following years though, people began leaving a starting rival companies. Yoshinosato took over as the president/promoter in 1966 and continued as the company's number three behind Giant Baba and Michiaki Yoshimura, eventually Kintaro Oki (Kim Ill) took him over as he neared forty. Though JWA managed to survive many problems throughout the late 60s, things finally unravelled with Inoki being fired and forming a rival company, Nippon TV pulling out, Giant Baba leaving and starting another rival company. The JWA folded in 1973 with its members going various places, Yoshinosato himself became a commentator for IWE and eventually had some involvement with All Japan. However, Junzo Hasegawa's later days were spent as the chairman of Rikidozan OB (alumni) meetings before his death in 1999.
