IBF Light Flyweight title holder Akira Yaegashi improved his record to 24-5 with a split decision victory over Martin Tecuapetla at the Ariake Colosseum in Tokyo, Japan.
The 33 year-old successfully defended his belt for the first after judges carded 116-113, 115-113 in his favour and 113-115 for the challenger.
In the co-feature, WBO Super flyweight champion Naoya Inoue made it ten straight wins as a pro by out-pointing David Carmona decisively 118-109 (twice) and 116-111 after twelve rounds.
Inoue is widely regarded as one of the top prospects in boxing at the tender age of 23, having already secured world titles in two weight classes.
The talented boxer won a world title in just his sixth fight by defeating Adrian Hernandez, and since then, Inoue has gone from strength to strength to recently be linked to facing pound for pound star Roman Gonzalez.
Members of the Inoue family also celebrated triumphs on the bill as Takuma stopped Afrizal Tamboresi early to move to 7-0, whilst welterweight Koki made light work of Bimo Jaguar to put a trio of victories in the record books.
In further action, super bantamweight Victor Lopez shocked previously unbeaten Ryo Matsumoto in the fifth round to put an end to a 17-fight winning streak, whilst featherweight Toru Kiyota pushed to 4-0 with a third round win over Kanehiro Nakagawa.
