At the moment all WOWOW have released in regards to details is that the broadcast will be live on November 28th from the Xebio arena Sendai, in Miyagi and will feature a world title bout.
Given how vague the information is it has left fans guessing as to who is going to be fighting on the card.
At the moment it seems clear that a number of fighters can be ruled out. These include some current champions, like Kosei Tanaka (5-0, 1), who we know will be defending his WBO Minimumweight title on December 31st, and Takashi Miura (29-2-2, 22), who will be defending his WBC Super Featherweight on November 21st as well as the likes of Shohei Omori (15-0, 10) and Ryo Matsumoto (15-0, 13), who have scheduling conflicts, as well as those who have never won a Japanese or OPBF title, who simply aren't allowed to challenge for a world title in Japan until they "graduate" with a domestic or continental belt.
Some of the names linked to the date have been:
Go Odaira (12-4-3, 1), who recently vacated the Japanese title to focus on a world title shot
Ryo Miyazaki (23-1-3, 14), who may be getting a long awaited Light Flyweight world title
Yu Kimura (17-2-1, 3), who would also be looking for a Light Flyweight title fight, and is penciled in for a fight in November
Akira Yaegashi (22-5, 12), who is free though is expected to be in action in December on a yet to be announced Ohashi card
Koki Eto (17-3-1, 13), who could fight for a belt at either 112lbs, possibly against Amnat Ruenroeng, or at Super Flyweight
Suguru Muranaka (22-2-1, 7), who would again be looking for a shot at Flyweight
Toshiyuki Igarashi (21-2-1, 11), who would be hoping to get a Super Flyweight world title fight
Teiru Kinoshita (22-1-1-, 5), who has spoke about getting a fight with IBF champion McJoe Arroyo
Takahiro Yamamoto (16-4, 13), who could challenge for a Bantamweight title against WBO champion Pungluang Sor Singyu
Shingo Wake (19-4-2, 11), who is the IBF mandatory challenger at Super Bantamweight and has been linked in the past to a fight with WBO /WBA "super" champion Guillermo Rigondeaux
Hozumi Hasegawa (34-5, 15), who is eligible for a Featherweight title fight even if the options are limited in terms of competition
At the moment we're still awaiting the details of the show, though it should be noted that a year ago, when WOWOW did their last "Touch" event, fans got the chance to see a double world title show with Takashi Miura defending his WBC Super Featherweight title against Edgar Puerta and Roman Gonzalez defending his WBC Flyweight title against Rocky Fuentes, and also featured Ryo Akaho in a stay busy fight against Antonio Tostado Garcia. On that evidence it may be smart to favour Teiken fighters to be involved here, which would be Yu Kimura and Toshiyuki Igarashi from the above list, though Teiken have had a great working relationship with Shinei Gym fighter Hasegawa. As a result they would be the 3 most likely options in our eyes.
