At the weigh in Koseki scaled a little more than 101½lbs, slightly heavier than she was last time out, when she stopped Denise Castle in 8 rounds, and marginally lighter than her bout with Angor Onesongchaigym last March, however it has been around her typical weight since she first won the Atomweight title more than 6 years ago.
Alico, who has lost her last 3 bouts by stoppage, was was notably lighter, weighing closer to 100¾lbs, well inside the 102lb limit.
For Koseki this is her 15th world title defense as she looks to further prove her domination of the 102lb weight class. As for Alico, a huge under-dog for this fight, this is her first fight for a "Big 4" world title, though she has previously fallen short in a WIBA title fight against Samson Tor Buamas, who holds a win over both of these fighters.
It's fair to say that if Alico wins this may go down as the most shocking result in female boxing history, however for Koseki it's a case of being professional and keeping the clock ticking over as she hunts a bigger and better fight somewhere down the line.
