Gohakukai teaches Tomari-te and Goju-ryu separately. The founder, Tokashiki Iken, learned Tomari-te first, and after receiving a license to teach studied Goju-ryu. Currently, students are taught Goju-ryu first, and begin learning Tomari-te after a year or two of training.
Nakasone did learn Tensho from Higa Seiko, who was his friend. He was not, however, a Goju-ryu stylist. Similarly, Tokashiki Iken was licensed to teach Tomari-te before he began his study of Goju-ryu. The two styles are taught separately in his association.Yes, e.g. their Wankan seems to me to have quite distinctive Goju flavour in it (although my experience with Goju ryu is limited to mainly Youtube ). The style's lineage goes like this: Matsumora - Nakasone Seiyu - Tokashiki Iken and both Nakasone and Tokashiki have practised Goju ryu, so to call this style Tomarite is a bit of a stretch.
That is the website of the Tokai branch, located in Mie Prefecture, Japan. It was developed by one of the students of the branch chief, and reflects his own understanding and ideas. It may or may not coincide with the feelings at hombu dojo.
