Oriental and Pacific Boxing Federation

The Oriental and Pacific Boxing Federation (OPBF) is a professional boxing organization that sanctions title fights in the Asian and Pacific region.
History.
The OPBF was formed in 1954 by the Japanese, Korean, and Filipino boxing commissions. It was originally named the Orient Boxing Federation, but changed to the Oriental and Pacific Boxing Federation when the Australian National Boxing Federation joined in 1977. Members of the OPBF regional group are Australia, Fiji, Guam, Hawaii, Hong Kong, India, Indonesia, Japan, Korea, Mongolia, New Zealand, Philippines, Samoa, Taiwan, Thailand and Tonga.
The OPBF helped form the World Boxing Council in 1963 and is currently affiliated with that organization.
Members.
15 national commissions and 3 regional commissions (Hong Kong, Guam and Hawaii).
Controversies.
The OPBF ratings have been criticized numerous times. The ratings released in January 2005 had the undefeated #1 super flyweight Z Gorres passed up by three fighters, including a previously-unranked Prosper Matsuura jumping to #3, after an impressive win. Additionally, the undefeated Reynaldo Bautista dropped from #4 to #5 after a defense of his WBO Asia Pacific bantamweight title. The previously-unranked Japanese fighter Jun Toriumi catapulted to the #1 spot and won the title soon after.
The following year, a new batch of ratings drew further criticism. WBO Asia Pacific super featherweight champion Czar Amonsot, who was previously ranked #3, dropped out of the top 10 after knocking out Victor Mausul for the title and defeating Cristian Favela. Unranked Jimrex Jaca was moved to #1. Apart from this, former OPBF super featherweight champion Randy Suico had relinquished his title to move up to lightweight, and was immediately ranked at #1 in his new weight class in the new rankings. The previous #1, Shunsuke Ito, had just won the Japanese lightweight title by stopping his opponent in the second round and was in line for a OPBF title shot against reigning champion Chikashi Inada.
In September 2017, undefeated Filipino prospect Edward Heno won the vacant OPBF light flyweight title on his second attempt. However, he was stripped of the belt and dropped to number four in the rankings after he was unable to defend it at that year's OPBF convention in Puerto Princesa in November, even though the winner of a vacant belt normally gets 90 days to defend it.
