The first notable September 22nd was all the way back in 1960 when Thai legend Pone Kingpetch successfully defended his World Flyweight crown against Pascual Perez with an 8th round TKO. This was the second meeting between the two men who had fought 5 months earlier, in the first meeting Kingpetch took a split decision over Perez and became the first world champion from Thailand. The second bout was Kingpetch's first and saw him fighting in the US for the first and only time in his legendary career. Kingpetch would hold the title until October 1962 when he lost it to Japanese great Fighting Harada though he would regain it the following year to become Thailand's first 2-time world champion and in 1964 he became a 3-time world champion!
In 2008 Nobuhiro Ishida scored a 12 round split decision over Marco Antonio Avendano to become the mandatory challenger for the WBA Light Middleweight title. Instead of getting a shot at the title however Ishida would rematch Avendano the following year to claim the interim world title title. Unfortunately for Ishida he was unable to secure "real" title fight though would defend the interim title twice before losing a controversial decision to Rigoberto Alvarez, the older brother of Saul "Canelo" Alvarez. It was it a none-title fight that Ishids scored his most famous win, stopping the then unbeaten James Kirkland inside a round in one of the biggest upsets in recent years.
In 2011 it was the turn of the female fighters with a trio of female world title fights in Japan.
One of those 3 fights saw Mari Ando defeat Thailand's Amara Kokietgym to claim the previously vacant WBA Atomweight title. Ando, who later hold a world title at Minimumweight, would manage 1 successful defense before losing the title to the great Ayaka Miyao in 2012.
At Minimumweight fans saw the great Naoko Fujioka retain her WBC female Minimumweight title with a 9th round TKO victory against Kanittha Kokietgym. This was Fujioka's first successful defense of a world and since then she has become one of the greatest active female fighters, arguable the #1 pound-for-pound female fighter on the planet.
The other bout saw Etsuko Tada retaining the WBA female Miniumweight title with a 10 round decision against Nongmuay Kokietgym. Tada would hold the title until 2013 when she lost it to Mexico's Anabel Ortiz.
