Two more issues of Black Belt were published in 1963 and six more came out in 1964. Problems associated with production and distribution were worked out pleasing the growing legion of subscribers. Highly vocal Japanese karate-man and founder of kyokushin karate, Masutatsu Oyama, made his presence felt in 1963 by telling readers of Black Belt that he had announced a challenge to schools in his homeland that they compete in no holds barred contests in which the winner would take over dojos of whoever were the losers. It was no surprise that no one took him up on it. Oyama then wrongly claimed that all styles of karate would be unified into one system within ten to fifteen years. Oyama and Ed Parker were both wrong in their predictions that karate would be in the Olympics with the next ten years.
