About Sentani-Ryu Aikido
An overview of Aikido, Sentani-Ryu, and what to expect as a new student.
Ranking in aikido, as in many other Japanese martial arts, follows a Kyu-Dan system. Sentani-ryu assigns 10 Kyu ranks, followed by eight Dan ranks (black belt). Testing is an effective way to evaluate a student’s progress and technical proficiency in the art, and formalize their progression through it over time.
For each rank, a minimum number of practice hours and elapsed time between testing is required, along with a set of techniques that the student should be able to demonstrate competently.
