Notes/コメント：The International Karate Organization Kyokushinkaikan (Matsui/IKO-1) So Honbu Dojo in Ikebukuro, Tokyo was set up by the IKO-1 after they vacated the original Honbu Dojo. It is about a 5 minute walk away from the original building. These days, I believe it functions more like a regular neighborhood dojo and all the important events are held at the new Daikanyama Dojo.
この道場は極真会館（松井派）の現在総本部道場です。オリジナル本部道場から、徒歩５分。
