Mini flyweight
a weight category in various sports, especially boxing and martial arts
Mini flyweight, also known as paperweight (early), minimumweight, strawweight, or super atomweight, is a weight class in combat sports.
Boxing
In professional boxing, boxers in the minimumweight division may weigh no more than 105 pounds (48 kg). This is a relatively new weight category for professionals, first inaugurated by the major boxing sanctioning bodies between 1987 and 1990.
History
The minimumweight division was originally introduced in 1968 for the Summer Olympic Games under the name light flyweight. However, the division was not recognized by any of the four most widely regarded sanctioning bodies until the International Boxing Federation (IBF) in June 1987, when Kyung-Yung Lee knocked out Masaharu Kawakami to become the inaugural champion.
The division was then later recognized by the World Boxing Council (WBC) in October 1987, the World Boxing Association (WBA) in January 1988, and the World Boxing Organization (WBO) in August 1989, while Ring magazine did not begin ranking minimumweights until 1997 under the name strawweights and would not name a champion until 2024, when Oscar Collazo knocked out Knockout CP Freshmart.
Historically, the weight class has been dominated by Latin Americans and Asians, with only a limited amount of success coming from other nationalities.
Late 1980s (1987–1989)
In the early years of the division, fighters such as Napa Kiatwanchai found success defending the WBC belt. Hiroki Ioka also started out in the division, winning the WBC belt before finding success at light flyweight, flyweight, and super flyweight.
Other notable champions of this period included Nico Thomas, Jum-Hwan Choi, and Leo Gamez.
This brief starts where responsible research should: with the source description of “Mini flyweight” as a weight category in various sports, especially boxing and martial arts. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as a weight category in various sports, especially boxing and martial arts. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q282168. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1987, 1990, 1968 and 1988.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
