In Tadashi Nakamura's wonderful book Karate: Technique and Spirit he has photos and instructions for a sai kata he calls Ganki Dai. First this is definitely not Gekisai, dai, dai ichi, dai ni or sho. Does anyone know if this is Nakamura Sensei's creation or if it comes from Kyokushinkai or another source? Also if anyone knows the kanji for the name I am interested in that also. The book is not just a great resource but is extremely well put together from an artistic perspective. On similar level to Mas Oyama's This is Karate. Tak Kubota also had a book with beautiful black and white photos that is on a similar level. Thanks for any help. Len McCoy
