Of the two Japanese fighters it's arguably Naoto Uebayashi who is better known. The talented 27 year old reached the B Class tournament final last year in the Super Bantamweight division, though was held to a draw by the more experienced Yusaku Kuga. Since the set back he has scored a notable victory over Filipino Marjohn Yap.
Uebayashi will be facing his second successive international opponent when he returns to face the experienced Anis Ceunfin (16-18-5, 6).
Whilst Ceunfin has got losses piling up on his record in recent years he has proven to be tough and has often been brought in to Thailand to get top Thai's some rounds under their belt. This has seen him sharing a ring with world level fighters including Chatchai Sasakul, Denkaosan Kaovichit, Tepparith Kokietgym and Tabtimdaeng Na Rachawat. He has also fought in Japan before, losing a decision to Hirofumi Mukai.
Although a novice in terms of professional experience Uebayashi should have more than enough to defeat his experienced though limited foe.
As for Marugame, who last fought in November out pointing Filipino Roman Canto over 6 rounds, his opponent has been named as Falazona Fidal (25-39-1, 8) a man with more than 30 times as many professional fights as Marugame.
Fidal, like Ceunfin, has been in there with numerous top fighters including Pongsaklek Wonjongkam, Hussein Hussein, Vic Darchinyan, Tabtimdaeng Na Rachawat, Denkaosan Kaovichit, Ratanachai Sor Vorapin and Oleydong Sithsamerchai. He has also fought in Japan in recent years being stopped in 7 rounds by Ryosuke Iwasa.
As with Uebayashi we do favour the Japanese fighter here, who was a former national champion and also competed at the 2009 World Amateur Championships.
