IKO President Kancho Matsui's speech 
"Thank you for your attendance here at Sosai Masutatsu Oyama's 20th Memorial Ceremony.
This year marks a huge milestone for the Kyokushinkaikan as we celebrate our 50th anniversary, as well as memorialize the 20th year since the passing of our beloved founder, Sosai Mas Oyama.
This solemn ceremony is usually held at Mitsumine Shrine at Chichibu Mount Mitsumine where Sosai's spirit is entombed. We are gathering today instead at Tokyo Metropolitan Gymnasium, our time-honored Championships site, in order to remind ourselves of Sosai Oyama's Kyokushin Spirit of keeping our heads low, eyes high, reserved in speech with hearts as one, and basing ourselves on the belief of filial piety. In this arena, we dedicate ourselves forward towards the next 50 years, and to the eternity of the Kyokushinkaikan. 
My sincere gratitude and respect goes to everyone here today. Thank you for your everlasting support.
We are pleased to present The International Karate Friendship in honor of Sosai Oyama. In witnessing today's Championships, I hope you will gain a complete understanding of Sosai Oyama's objectives and hope for the Kyokushinkaikan.　
Once again thank you for joining us today. I sincerely appreciate all your support."
