It's not a given however that Koseki will retain her title this time around as she battles Britain's Denise Castle (2-0, 2). On paper it's a clear mismatch but in actuality this could very easily be the toughest bout Koseki has ever been involved in.
Castle may be a pro boxing novice but she is a former Muay Thai legend who turned to boxing earlier this year in search of a new challenge. As a Muay Thai fighter Castle was a WBC champion and it appears that her aim in professional boxing is to do the same.
Koseki is a tough, rough, nasty and mean fighter. She lacks KO power but is very much a fighter with a street fighters mentality. In fact pound-for-pound it's hard to think of a tougher female boxer than Koseki but in Castle we have an equally tough and proven competitor.
Although this is a very tough bout Koseki does hold numerous advantages over her British opponent. At 42 Castle is an old fighter, she's very fit but has had a long athletic career having been a runner before turning to combat sports. Koseki will also be fighting at home and there is sure to be support for the Tokyo fighter who is fighting at home. Also Muay Thai and boxing are different sports and Koseki has the clear edge in boxing experience, not just in rounds and fights but also quality of experience having previously fought Samson To Buamas, Nao Ikeyama, Masae Akitaya and Nora Cardoza amongst others. To date Castle has fought no boxers of note.
For both fighters this is a huge bout. For Castle it's a chance to leap to the top of the boxing world in her division and replicate her Muay Thai success. For Koseki it's a national record and further proof of her dominance at 102lbs. It's a really great fight. We do favour the champion here but we know she's in for a very, very tough contest.
