This is Shōhatsutō (初発刀), the first kata of the Gokyō within the Kihon Iaidō of Ittō Tenshin-ryū.

To preserve the integrity of the Ittō Tenshin-ryū, Yamate-ryū, and Goseki-ryū, it is fitting to declare where, and from whom, authentic instruction in these traditions may rightly be obtained.

The Ittō Tenshin-ryū is a powerful tradition!

Its unwavering purpose has informed deshi since its inception. While the words pointing to essence may change from time to time, the development of a powerful and orderly being remains.
