At the end of February, a group of international students graduated from the Tokyo-based Yoshinkan Honbu Dojo, one of the most intensive martial arts training centers in the world.

Yoshinkan (meaning "hall for cultivating the spirit") is a style of aikido founded by Gozo Shioda after World War II. Made famous by the controversial book "Angry White Pyjamas" by Robert Twigger, the Senshusei Aikido training course was initially started at the dojo in 1957 to train members of the Tokyo riot police. In 1991 the 11-month program opened its doors to applicants outside the police force, and since then the course has attracted recruits from all over world.

One such recruit, Englishman Andrew Carter, 24, who graduated from the course this year, spoke to The Japan Times about his motivations for starting the program and his experiences over the nearly yearlong course.
