Welcome address

Mr. Nobuyuki Suga
1st All Japan Championship Winner

On the occasion of the opening of the 53rd annual All Japan Bogu Karate Tournament, I would heartily like to extend my appreciation for all those who have devoted time and effort in hosting the 53rd annual All Japan Bogu Karate Tournament magnificently and who have back up this tournament warmly.

The first annual national tournament of Bogu Karate was held in 1954. Since then, the tournament has taken place over 53times, though there were some years that the tournament was not held by the agreement of all schools. Renbukai has made some noted contributions to the development and prevalence of Bogu Karatedo as a pioneer for a long time.

I hope that all participants will play the fair games in this tournament with pride as representatives of each prefecture.

We have pursued the Karatedo with the aims of the discipline of our spirits and bodies as well as the improvement of our “Waza”. We should think that both aims are united. There is a lofty ideal “the growth as a human through Karatedo” under the above-mentioned way of thinking. I believe firmly that the many things you experienced through Karatedo so far have been useful to your valuable character building and that you will bring your experience into full play to contribute to the society.

In this tournament, I am sure of new history and impressions that will be created by you gathered here from all over the country. Lastly I would like to extend my warmest best wishes to you for progress in your most valuable work and I trust that Bogu karatedo will move ahead and make progress steadily.

Bogutsuki Karatedo

Before the World War Ⅱ, people feared karate because karatekas adhered to the power of blow too much alike judo, kendo and other martial arts in those days. Therefore karate was accepted by very few people as an unsafe and mysterious martial art. Our pioneers with foresight took notice of inevitability that the true prosperity of karate would be realized by the safe and fair match closer to actual combat. They pursued the question of how karate should be instructed with Bogu (protective gear) by trial and error consistently. Their strong will has been succeeded to until today. Also, there are some records that the late Mr. Kenwa Mabuni (Okinawan karateka), the late Mr. Chojun Miyagi (Okinawan karateka), and societies for research and investigation in some colleges carried out experiments and researches about Bogu in the early Showa period. Those pioneers recognized the above-mentioned inevitability about 70 years ago.

With the Japanese tremendous economic restoration during 70 years after the War, many sports including martial arts developed so that Japanese athletes could lead the world or fight equally with foreign ones. Karate is not an exception, either. It was natural that Japanese martial arts were accepted better as universal sports like judo, the better they infiltrated in the world and became internationalized. It was inevitable that proper modification or change was required in exchange for universalization. There is no sport that puts a slight on safety and fairness.

As fencing and combative sports, etc. were applied to tournament, generalized and became bases of today’s sports gradually in ancient Europe, it is an indispensable trend that Japanese martial arts are improved progressively without ticking to old convention with modernization of human race. The efforts for prevention of hazard, etc. need to be understood and supported fully by the public opinion so as to accomplish the further prevalence of karate and the adoption of karate in school curriculum. Moreover, as people come to practice karate all over the world and international exchange become popular, it is reasonable that the safety in common with each country and the clear match rules should be introduced in karate. We take a standpoint that the karate spirit as a traditional martial art should be respected fully but that the application to tournament and the universalization of karate as sport is inevitable historically.

We made efforts to evolve and promulgate Bogu Karatedo one after another, and accomplished the hosting of the 1st annual All Nippon Bogu Karatedo Tournament in 1954 at last. It must significantly contribute to the evolution of Bogu Karatedo for comrades who practice Bogu Karate to gather from all parts of the country and unite in the annual All Japan Bogu Karatedo Tournament every year. We are firmly convinced that this tournament will direct the right way of World Karate, not Japan Karate, together with the appearance of safer protective gear Strongman
