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. 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, which led to Mutoh resigning as the chairman of the board and leaving the promotion. 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. During the rest of June, Masakatsu Funaki, Kaz Hayashi, Shuji Kondo, Ryota Hama, Hiroshi Yamato, Masayuki Kono, Koji Kanemoto, Minoru Tanaka, Yasufumi Nakanoue, Kai, Seiya Sanada, 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".
