Although the show hasn't been officially announced it seems tickets were made available at the start of this month for the show which will be headlined by an IBF Female Light Flyweight Naoko Shibata (15-3-1, 4) [柴田 直子] defending her title in a rematch against Mexican foe Maria Salinas (11-4-3, 4).
Shibata and Salinas fought to an action packed split decision draw last year, with Salinas's team believing she had deserved the win and if pia are right the rematch will allow the fighters to work who is better in the ring.
For Salinas a rematch would be her third world title out and her third bout in Japan, where she has drawn with Shibata and been beaten by Etsuko Tada. As for Shibata the bout will be her 5th defense, and see her back in the ring 4 months after fighting a stay busy bout with Tanuthong Sor Kunlawong.
The other title bout, according to Pia, will be a WBA female Minimumweight title bout that will see Satomi Nishimura (9-2, 1) battle against Yunoka Furukawa (7-1-2, 5) for the vacant title, which will presumably have been vacated by Anabel Ortiz come fight night.
For both Nishimura and Furukawa the bout will be their first world title bouts, though both have won regional titles recently Nishimura claiming the PABA female Light Flyweight title last December and Furukawa claiming the OPBF crown this past February.
Again it must be noted that Pia are selling tickets despite their being no formal announcement of the show. This may mean that the card won't take place or it could mean Pia have jumped the gun and that is set to be announced very shortly.
