From the Observer site:
Stardom founder and booker Rossy Ogawa was fired today by Bushiroad after being accused of attempting to poach talent to leave the promotion.
The story dates back about nine months when Bushiroad execs started overruling Ogawa to the dismay of both himself and talent and some of the more outlandish booking decisions. Ogawa constantly being overruled on booking and business decisions by Bushiroad Fight President Katsuhiko Harada led to his decision to leave the company. Harada was later replaced by Taro Okada in that position in November. However this continued under Okada and Ogawa had already made plans to leave.
He had been under the impression that he would have autonomy on booking and business when he sold Stardom to Bushiroad in 2009. That included a five year-non compete.
It was known that the affiliation between the two sides was going to end on 2/18 as Ogawa had given notice some time back. At first, today’s show was to be his final show, but then the sides agreed to sever ties on 2/18. However, Bushiroad decided to get ahead of the story two weeks early and made the announcement publicly that he was fired after the talent was told in a meeting following today's show in Osaka.
A lot of the talent is loyal to Ogawa, who founded the company and gave most of the women their career breaks. Expect several departures from the group in March, when most of the contracts expire. The only wrestler under a longer term commitment to Stardom is IWGP Champion Mayu Iwatani, because of the movie on her life coming out.
Bushiroad had known about talent leaving and some were given legal threats in recent weeks. Those who are leaving wouldn't be doing so until their contracts expire. This is part of the story of why Giulia will not be wrestling in Chicago and had said she was taking time off in March, when her contract expires.
Ogawa is not going to WWE.
Okada and Bushiroad Fight merchandise manager Oyama will take over as the bookers for Stardom effective immediately. The two don't have any background as bookers although Okada was part of a pro wrestling club while in college that staged matches.
