1991年より他流空手を学び16歳で士道館全日本大会、第三位に入賞。1996年、養秀会に入会、大阪本部長に就任。同年18歳で白蓮会館全日本大会に初出場。第三位入賞を果たす｡
翌年行われた養秀会全日本大会ではオール１本勝ちで優勝。以後養秀会のエースとして全国の数々の大会で活躍。養秀会全日本大会では大会史上初となる４連覇を達成。

2002年にはＫ-１でおなじみの魔裟斗、ジェロム・レ・バンナ、レイ・セフォーなどが保有するISKAのフルコンタクト空手　世界ミドル級王者となる。2004年に行われた白蓮会館世界空手道大会では 並み居る強豪を破り見事準優勝に輝く。
同年、本格的に指導を開始。2005年8月には少年部上級クラスを設立。少年部も活躍を始める。
2008年3月に養秀会、宗家山元勝王から独立の許可を受け12年間所属した同会を円満に退会。
そして2008年4月、正しい道を歩む者、歩もうとする者を支援、応援していきたいというおもいをこめて「空手道・正援塾」を設立。

正援塾は武道空手です。空手を通じ肉体的な強さと精神的な強さ両方を学ぶ場所です。空手道を通じて得るものは叩く強さ蹴る強さだけではありません。私生活で困難な道に立ち向かっていく強さ、逆境を乗り切る強さを身に付けるのも空手道です。
日々の練習を通じ、道場だけでしか通用しない小さな強さではなく、どんな道にも立ち向かっていける正しい心と体を育てていきたいと思っております。
また代表である私自身も修行者であることに変わりはありません。生徒と共にさらに上を目指してがんばって行きたいと思います。

Representative: Masataka Wakatsuki
He started learning karate in 1991, and he took third place at the Shidokan All Japan Championship at the age of 16.
In 1996, he joined Yoshukai and became the chief instructor of the Osaka branch.
The same year, he participated in the Byakuren Hall All Japan Championship for the first time at the age of 18. He came in third place.
The following year, he won all his matches by ippon and came in first at the Yoshukai All Japan Championship.
Since then he has participated in numerous competitions in Japan as one of Yoshukai’s top competitors.
He became the first-ever four-time consecutive champion at the Yoshukai All Japan Championship.
In 2002, he became the first middle weight World champion in ISKA full contact karate, a title later held by Masato of K-1 fame, Jerome Le Banner, Ray Sefo, etc.
In 2004, he successfully became vice-champion at the Byakuren Hall World Karatedo Championship by defeating tough fellow competitors.
That year he officially began instructing. In August 2005, he established the Youth advanced level class. The regular Youth division also started to flourish.
In March 2008, he received approval from the Yoshukai headmaster, Katsuou Yamamoto, to become independent, and he resigned from this society, to which he had belonged for 12 years, with gratitude for all that he had learned.
In April 2008, he established “Karatedo – Seienjuku” with the hope to encourage and support the ones who walk — or try to walk — on the righteous path.

Seienjuku is a budo karate.
It’s a place to learn your physical and mental strengths through karate. What you obtain from karate is not only the strength to punch and kick. Karate-do also reveals how to obtain the strength to face hardships in everyday life, and how to overcome adversity.
Through everyday training, I want to nurture not the small strength that can be used only in the dojo, but a righteous mind and body, which can face any obstacle.
Furthermore, there is no doubt that I am also a trainee. I want to work hard to achieve a higher level together with my students.
