To help Yoshikawa prepare for that fight she has been training with female boxing royalty in Mexico with the Japanese novice spending time sparring with former world champion Mariana Juarez (40-7-3, 17).
The sparring, which we've not seen footage of, was said to have been at a very high class with Juarez getting the best of it over-all though much of that was down to her size advantage as well as her experience. Saying that however both fighters were very complimentary of each other and their abilities.
Notably Juarez will herself be in a major bout in the coming weeks as she battles against Japan's Naoko Fujioka (12-1, 6) in a Super Flyweight world title eliminator on March 14th with Fujioka traveling over to Mexico for that bout.
