Naoya Inoue made the first defense of his 108 lb. title, battering overmatched challenger Samartiek Kokietgym in 11 rounds Friday evening in Tokyo, Japan. 

The bout served as the chief support to the World flyweight championship between Akira Yaegashi and Roman Gonzalez.

Inoue was as dominant in his first title defense as he has been in every other bout since turning pro in October '12. The 21-year old enjoyed significant advantages in height, reach and overall skill, putting them all to proper use as Kokietgym was overwhelmed across the board.

Worse for the visiting challenger from Thailand was that the defending champion never slowed down. Inoue poured on the attack round after round, landing at an alarmingly high rate, most of which were power punches that slowed Kokietgym to a crawl. 

The beatdown was brought to a merciful end in round 11. Kokietgym was under siege from a hailstorm of punches before finally rescued from absorbing further - and unnecessary - punishment.

Inoue cruises to 7-0 (6KOs) with the win. The rail-thin titlist made the first defense of the belt he viciously acquired in a one-sided drubbing of Adrian Hernandez, the top rated fighter at 108 lb. who had no answers in watching his second title reign end with a whimper in April.

Kokietgym falls to 17-5 (5KOs), as he is now 0-4 outside of Thailand. The loss ends a nine-fight win streak, comprised entirely against pedestrian opposition. 

NON-TELEVISED UNDERCARD (ALL RESULTS FROM )

Unbeaten Ryota Murata was forced to go the distance for the first time in his career, but kept his perfect record intact with . Scores were 110-90, 99-91 and 98-92 in favor of Murata, the rising middleweight prospect who captured Olympic gold for Japan in the 2012 London Olympics.

Any designs Denkaosan Kaovichit had on making another title run came to a crashing halt in Tokyo. The former 115 lb. titlist was crushed in eight rounds by unbeaten bantamweight prospect Ryo Matsumoto, with .

Kaovichit enjoyed a title reign of more than a year, including an Oct. '09 points win over Daiki Kameda. His stay as champ came to an end in his following fight, losing to Kameda in their rematch four months later. The closest he's come to reclaiming past glory was a brief interim title run before losing to Kohei Kono in eight rounds earlier this year. 

The loss to Matsumoto is perhaps the start of a new role for Kaovichit as a high-profile opponet. The 38-year old Thai boxer is now 63-5-1 (26KOs). 

Matsumoto rolls to 12-0 (10KOs), picking up by far the biggest win of his career. 

Takuma Inoue has yet to make a move without older brother Naoya on the same card. The 18-year old flyweight prospect continued that tradition on Friday, appearing on the undercard in support of the defending champion, as he cruised to a 2nd round stoppage of debutant Chanachai Sor Siamchai. The younger Inoue is now 3-0 (1KO), following his first two pro bouts going to the scorecards in six and eight rounds, respectively.
