Isogane gets the stoppage
The scheduled 8-round flyweight bout ended one minute into the sixth round. eFight’s event report records a TKO, while Tapology lists the same finish time. There were no judges’ cards in the result.
Isogane, a Japanese prospect from the Ohashi Gym, earned a stoppage over Yamamoto, who was ranked fourth in the Japanese flyweight division at the time. The result was reported as Isogane’s sixth consecutive win.
Part of a major Yokohama boxing card
The May 28 Lemino Boxing card took place at Yokohama BUNTAI and featured world-title bouts involving Yoshiki Takei and Masanori Rikiishi. Takei retained his WBO bantamweight title with a first-round TKO of Yuttapong Tongdee. In the co-main event, Eduardo Núñez won the vacant IBF junior lightweight championship over Rikiishi. Isogane and Yamamoto competed earlier on the same program.
A stoppage win can strengthen a boxer’s position, but the result alone does not confirm a ranking change or the next opponent. No future fight was announced in the event report. Any prediction about an immediate title shot, rematch or specific next bout should therefore be treated as unconfirmed.
