On November 1, 2012, IT company Speed Partners bought 100% of All Japan Pro Wrestling (AJPW) shares from main shareholder Keiji Mutoh and his business partners for ¥200 million.[11][12][13] In late May 2013, Speed Partners president Nobuo Shiraishi fired AJPW president, Mutoh's longtime right-hand man Masayuki Uchida, and took over as the promotion's new president himself effective June 1,[14][15] which led to Mutoh resigning as the chairman of the board and leaving the promotion.[9][12][16] For the next weeks, Mutoh attempted to buy back his shares of the promotion from Speed Partners, but eventually gave up the attempt before the end of the month.[9] During the rest of June, Masakatsu Funaki,[17][18] Kaz Hayashi,[17][18] Shuji Kondo,[17][18] Ryota Hama,[18][19] Hiroshi Yamato,[18] Masayuki Kono,[18][20] Koji Kanemoto,[20] Minoru Tanaka,[20] Yasufumi Nakanoue,[18][20] Kai,[18] Seiya Sanada,[21] and Andy Wu all announced their resignation from AJPW out of loyalty to Mutoh and left the promotion following a June 30 event in Ryōgoku Kokugikan, which marked the official end of the eleven-year-long "Mutoh All Japan".[9][22]
