Despite a year of battling the case isn't over for Takayama who, this morning, revealed that things were being taken to the Japan Sports Arbitration Agency (JSAA).
It seems like this is probably going to be the last chapter in the story if Takayama loses, though he will be hoping that the mediation goes in his favour and has the petition to show there is a huge amount of support in his favour.
The fighter appears to have been unable to tie the JOC and JBC down for meetings which is part of why he has gone to the JSAA to act as a neutral party.
The JBF seem to be against any professional fighters returning to the amateur ranks, due to the fact professionals fight for a living whilst amateurs are typically part of an education. That's despite the fact that amateur fighters are allowed to compete at the Olympics, and several did in 2016 with the likes of Amnat Ruenroeng and Hassan N'Dam both doing so, though neither did particularly well.
It's worth noting that Takayama often looked to be a pioneer in the sport. He chased the IBF title around the globe well before the JBC recognised the title, chased the "Grandslam" crown of winning versions of all 4 world titles . This however is looking like a tougher challenger than any of his other ones.
