“The ring where Kickboxing was born”

The original Kickboxing · Japan, since 1964

The origin

History

Kickboxing is a martial art of Japanese origin, created by boxing promoter Osamu Noguchi in 1964, who also founded the first association in the world: WKBA, World Kick Boxing Association.

On his travels as a promoter, Mr. Noguchi discovered Muay Thai in Thailand. He promoted the event known there as “Japan vs Thailand”, featuring the Japanese fighters Osawa, Nakamura and Kurosaki (Osawa and Nakamura defeated the Thai fighters, and Kurosaki lost by knockout).

With this 2–1 victory, Mr. Noguchi returned to Japan with a new project which he named Kickboxing, without modifying any of the strikes permitted in Thailand, all of which are still allowed today: punches, elbows, kicks, knees and clinch.

In 2009, Mr. Noguchi named Kaicho Ihara as his sole successor, handing over the Presidency of WKBA and all its rights. Since then, WKBA has grown as the original and most important professional Kickboxing organization in Japan.

Today, more than 50 years after its creation, millions of people around the world practice Kickboxing and enjoy all its benefits as a martial art, self-defense, contact sport and fitness discipline, at both professional and amateur level, thanks to the conviction of great men who make history.

The organization

WKBA

WKBA (World Kick Boxing Association) is one of the oldest contact-sports organizations in the world, directly linked to the very birth of Kickboxing as a discipline. It was originally founded in Japan in 1976 by Osamu Noguchi, the celebrated boxing promoter historically recognized for creating both the term and the sport of Kickboxing.

It is regarded as the first international kickboxing association in history devoted to the purely Japanese style. During the 1980s, 90s and 2000s, WKBA served as platform and springboard for legendary fighters, and under its direction unified official bouts were promoted with the most prestigious stadiums of Bangkok, validating the level of Japanese kickboxers under traditional rules.

Before his passing, Osamu Noguchi officially named the legendary master Shinichi Ihara — Ihara Kaicho — as his sole heir and successor at the head of the organization. Today Ihara Kaicho serves as global president of WKBA and of Shin Nihon Kick Boxing Association (SNKA), and the organization keeps the essence of Budo and traditional Japanese kickboxing alive through branches in Asia, Europe and South America, with a very active WKBA Argentina. The current board features international figures such as Yu Kawakubo, Chinto Mordillo and Diego Gonzalez La Volpe.

“Nobody wins a fight by retreating, or without showing a combative attitude that reflects the true spirit of Kickboxing.”

Ihara Dojo, Tokyo · 2013

Japanese boxing promoter and creator of Kickboxing. On his travels he discovered Muay Thai in Thailand and returned to Japan with a new combat project to which he gave a name of its own: Kickboxing.

In 1966 he founded the first kickboxing association in the world, and in 1976 the World Kick Boxing Association. Under his leadership, Kickboxing went from being a challenge between schools to a sport with rules of its own and international reach.

In 2009 he named Ihara Kaicho as his sole successor, handing over the Presidency of WKBA and all its rights, so that the legacy of the original Kickboxing would remain in the hands that knew how to safeguard it.

Words from the President

Message from Ihara Kaicho

Mr. Osamu Noguchi is the creator of Kickboxing and also the creator of WKBA, with more than 50 years of history.

On 25 October 2009, upon the retirement of President Noguchi, I assumed the presidency of WKBA and ShinNihon Kickboxing Association. Today we have founded the WKBA INTERNATIONAL section to develop the finest Kickboxing and to organize WKBA activities in the different countries.

I am certain that WKBA will develop the highest level of Kickboxing around the world.

“The true history of world kickboxing is tied to names like Noguchi, Ihara and Harinck, among many others. It is a great source of pride for me to be part of this new project together with Japan. My friend Chinto Mordillo, a friendship of many, many years, is the perfect glue to unite us all.”

New era

MMA

As a sports organization, from 2024 at the Korakuen Hall in Tokyo, WKBA broadened its vision in the promotion of disciplines such as MMA, including Bare Knuckle Fighting and Brazilian Jiu Jitsu BJJ-NOGI.

Mixed Martial Arts, known worldwide as MMA, is a full-contact combat sport that allows the combination of techniques from a wide variety of traditional and modern martial disciplines. Fighters may use both stand-up strikes and grappling and submission techniques on the ground.

Core base disciplines

To be competitive, MMA athletes train three main facets of combat:

Stand-up fighting (Striking). Uses Boxing, Muay Thai and Kickboxing techniques to master punches, kicks, knees and elbows.

Takedowns and transitions (Clinch and Wrestling). Integrates disciplines such as Olympic Freestyle Wrestling, Greco-Roman Wrestling, Sambo and Judo to take the opponent to the ground or defend against takedowns.

Ground fighting (Grappling). Relies heavily on Brazilian Jiu-Jitsu (BJJ) and Luta Livre to execute joint locks, chokes and control positions.

Essential rules at professional level

Although the sport was born with very few restrictions under the «Vale Tudo» concept in Brazil, modern MMA is strongly regulated to protect the athletes' health. Bouts are generally held inside a cage or ring.

Weight divisions. Fighters are strictly grouped by category, from flyweight to heavyweight, to guarantee fair bouts.

Duration. Standard professional bouts last 3 rounds of 5 minutes; title or main-event bouts extend to 5 rounds.

Prohibited actions. Strikes to the back of the head or spine, eye gouging, kicks to the head of a downed opponent, biting and low blows are strictly forbidden.
