Mitsuhiro Momota , better known as Rikidōzan (力道山), was a Korean-born Japanese wrestler who competed in sumo and professional wrestling. He was known as The Father of Puroresu, and one of the most influential persons in professional wrestling history. Initially, he had moved from his native country Korea to Japan to become a rikishi. He was credited with bringing the sport of professional wrestling to Japan at a time when the Japanese needed a local hero to emulate and was lauded as a national hero. He was inducted into the WWE Hall of Fame in 2017, becoming the first Korean inductee and the third puroresu star to be inducted after Antonio Inoki and Tatsumi Fujinami. He was killed in a street fight with a member of the Sumiyoshi-ikka in 1963.

50th State Big Time Wrestling was a professional wrestling promotion headquartered in Honolulu, Hawaii in the United States that promoted professional wrestling matches throughout Hawaii. The promotion was founded by Al Karasick in 1936 and became a member of the National Wrestling Alliance in 1949. In 1961, Karasick sold the promotion to "Gentleman" Ed Francis. Along with his business partner Lord James Blears, Francis created a "golden age" of professional wrestling in Hawaii that lasted throughout the 1960s and early 1970s, with 50th State Big Time Wrestling becoming one of Hawaii's most-watched programs. In 1979, Francis sold the promotion to Steve Rickard, who one year later sold it to Peter Maivia, who renamed it Polynesian Pro Wrestling. The promotion came to an end in 1988.
