International Secretary and International Relations


International Secretary Tom Callahan



Kancho (Chairman of Kyokushin-kan) Hatsuo Royama and his Honbu (headquarters) office presides over the Kyokushin-kan International Karate Organization. Mr. Takaaki Enami is Honbu’s general secretary, ultimately responsible for International relations, although he is currently focusing primarily on domestic (Japanese Branch) operations, a focus that resulted in the creation of “International Chairman” and “International Secretary.”

Shihan Hennie Bosman, chairman of the Kyokushin-kan International Committee, has been approved by Kancho to act as “International Chairman” in order to facilitate relationships between Honbu and world branches. Shihan Hennie Bosman subsequently appointed USA Chairman Shihan Tom Callahan to act under him as “International Secretary” to assist in these operations. This appointment was approved by Honbu. International Members experiencing difficulty contacting our International Headquarters may contact either Shihan Bosman, or Shihan Callahan at

Tom Callahan has been involved in the martial arts since 1972 starting at Mattson Academy’s Uechi-Ryu Karate in Boston. He studied for 4 years in Uechi-Ryu under Shihan Al Wharton, before turning his attention to boxing, where he trained for 2 years. He returned to the martial arts in college where he trained and taught with the martial arts college club. He took a break from training as he built his career in the music business and returned to training in mid 90’s in Kyokushin Karate studying under Shihan Patrick Fard in IKO-1. Shihan moved over to Kyokushin-Kan in 2008 and holds the rank of Yondan (4th dan), the honorific title of “Renshi Shihan” and he is the elected Chairman of Kyokushin-kan USA.


International Relations


Remember that Honbu (and most certainly Kancho!!)  WANTS TO KNOW its Branch Chiefs and Dojo Operators, and overseas BC’s and DO’s should develop ties directly with Honbu, at least so we know you! This is best achieved by attending our international events. Remember that Kancho and Honbu definately wants to develop INSTRUCTIONAL TIES with its BC’s, DO’s, and other instructors, and in this case, BC’s and DO’s should not hesitate to interact directly with Honbu, especially during, and regarding, international seminars. Ideally every national-level organization runs smoothly enough at home that all members support, and feel supported by, their Country Representative. However, Honbu understands that due to the vast fragmentation of Kyokushin both during and following Sosai’s lifetime, every branch has its own unique history and liniage, and Honbu wants to ensure that its members know that they can reach out to Honbu in important situations.

Members would do well to remember that the world is a big place and Honbu even has its OWN domestic issues to take care of (i.e. like any other country), so members should not contact Honbu over frivolous matters. Likewise, however, if any member had a serious issue that he/she felt should be brought to Honbu’s attention, Kancho would disapprove of that member for not reaching out.

Overseas BC’s and DO’s should keep in mind that the extent to which your country organization is developing ties with Honbu and Kancho, and bringing Kancho’s teaching to your country, is your responsibility. Please plan events! Please attend ours as much as possible! In Russia, Europe, and South Africa, the norm has become that Kancho or Honbu instructors visits those regions one or more times per year for seminars or tournaments. Likewise, instructors from those countries are the faces that are regularly seen in our instructors’ seminars. This type of interaction is the responsibility of every national or regional organization. Please do the best you can!
