For fans around the globe the key outlet for the bout will be Russian TV who will air the bout live, likely with an easy to find stream, as Russian streams usually are easy to get.
Unfortunately for those wanting to watch the fight on a Japanese broadcast things are a bit more frustrating, as is usually the case when it comes to the secondary level Japanese names.
The bout will be aired on September 13th at 00:55 on BS Fuji. Not only is on tape delay, by a few days, but it's also on BS Fuji and not the free to view Fuji TV channel, which have generally shown Obara's bouts.
We can partly under-stand the fight not being shown live but for it to air on BS Fuji just seems a bizarre choice from all involved with the channel having a small audience and not being available for many people to record. Thankfully though the Russian version will be widely available on the net and should mean those that want to see the bout will be able to see it.
