Seisho began training under his father in 1956 and then kobudo under Shinpo Matayoshi around 1965. The article provides some insight into the history of Uechi Ryu and training then versus now. One statement that caught my attention, given the history of the terms/translations for 'karate' used in Uechi Ryu which we have discussed at times before:
I started under the Uechi Ryu Kenkyu Sho organization in the Itokazu Karate Dojo in Mihara on Naha's east side. This was my father's dojo, and at that time he was still using the old Chinese character to write karate (Tang 唐) and we called karate todi.
So Seiki Itokazu was still using the character for 'China' hand decades after it had fallen out of favor on Okinawa. Was this common in Uechi dojo at the time? I can see them possibly wanting to continue using 'China' hand given Uechi Ryu's direct connection to the Chinese martial arts.
