Since that loss, back in May, Muranaka has been away from the ring. Thankfully his break does look set to come to an end shortly, with reports stating that the now former world title challenger will return on December 6th and take on former foe Ken Achiwa (11-12-5, 4) [阿知和賢], in what will be the second meeting between the two men.
The two fighters fought back in March 2013, with Muranaka taking a unanimous decision win over his countryman. Since then Muranaka's careerhas seen him not only fight for a world title, but also claim the Japanese Flyweight title, and score notable wins over Takuya Kogawa, Masayuki Kuroda, Renoel Pael and Hiroyuki Kudaka. Sadly for Achiwa his career has been relatively frustrating recently, with a 3-3-3 record since losing to Muranaka, losng to the likes of Yohei Tobe and Kenta Nakagawa in domestic bouts, and losing last time out in China to Xinghua Wang.
At the moment details of the card are scarce, though we are glad to see that Muranaka is making a ring return, and hopefully the break from the ring will do him some good, as he did take a lot of punishment from Yafai back in May.
