When a kingdom loses its independence, the people responsible for protecting it are forced to reevaluate their entire purpose. Following the 1609 Satsuma invasion and the formal annexation of Okinawa by Japan in 1879, the old Ryukyuan warrior class watched their traditional way of life disappear. Deprived of their titles, their administrative roles, and their right to carry weapons under modern police rule, these martial artists turned inward. Their training was no longer about defending a royal court or fighting on a conventional battlefield. Instead, they began practicing Te in private, treating the discipline as a way to preserve their dignity, strengthen their character, and maintain physical control during a time of immense cultural upheaval.
Shitsunen Tokumine lived right in the middle of this painful transition. Coming from the Pechin class in Shuri, he trained alongside respected practitioners like Choki Motobu under teachers such as Sokon Matsumura and Anko Itosu. These instructors passed down the core traditions of Shuri-te, but the laws of the new Japanese administration strictly outlawed the sword. Because of this ban, practitioners shifted their focus toward the six-foot wooden staff, the bo. The formal name for the bo that Isshinryu practitioners use today is a rokushaku bo. "Roku" means six and "shaku" is a unit of distance measurement, traditionally equivalent to the relative length of a practitioner's forearm. With the acceptance of the metric system, one shaku has been standardized to 30.3 centimeters, or slightly less than one imperial foot. Therefore, the rokushaku bo is approximately six imperial feet long.
In the late nineteenth century, tensions ran high between the displaced Ryukyuan gentry and the new authorities. During an encounter in the Tsujimachi district of Naha, Tokumine found himself facing a group of thirty armed police constables. Using his staff, he fought them with devastating efficacy and wounded several officers before being apprehended. The local government dealt with this defiance harshly, sentencing Tokumine to permanent exile on Ishigaki Island in the Yaeyama chain. Being cast out from his home in Shuri meant losing his community, his status, and his ties to family. Yet this difficult isolation also removed the formal routines of palace life, forcing him to look at his martial arts through the practical lens of daily survival.
On Ishigaki, Tokumine stripped his staff movements down to what actually worked. He removed wide swings and theatrical flourishes, focusing instead on short, direct strikes and steady footwork. His time on the island was not shaped by romantic folklore or legendary battles, but by the quiet reality of an aging practitioner refining basic mechanics with a piece of wood. Every movement had to count, and wasted effort was eliminated entirely. The exile meant to quiet him ended up producing one of the most direct, practical staff methods in Okinawan history.
We still have this practice today thanks to Chotoku Kyan, who spent his life studying how solid mechanics could compensate for a smaller physical build. Hearing about Tokumine’s skill, Kyan traveled out to the Yaeyama islands in 1910 hoping to learn from him directly. When he arrived, he found that Tokumine had already passed away. Rather than giving up on his journey, Kyan discovered that the master had practiced daily in the yard of his rented home. The landlord, a local farmer who had watched and memorized the forms, was able to demonstrate the movements for him. Setting aside the strict class distinctions that usually governed teacher and student relationships, Kyan learned the form from this working-class islander and brought Tokumine no Kun back to mainland Okinawa.
Tatsuo Shimabuku began studying under Kyan in 1927, spending over a decade learning Shorin-ryu along with this particular bo kata. When Shimabuku founded Isshinryu in 1956, he kept the core mechanics of Tokumine’s form, but he was not afraid to adjust the movements to match how people actually move and protect themselves. He recognized that certain classical habits had become outdated, so he aligned the staff work with the natural, upright principles of his empty-handed style.
Shimabuku changed how the weapon was held, doing away with the rule that the left hand always had to stay forward. That old habit came from the days when warriors had to clear a sword scabbard on their left hip, which made little sense for modern self-defense. By teaching students to lead with either hand and switch grips smoothly, he made the bo equally effective from both sides of the body. He also placed the form into the natural, higher stances of Isshinryu, which allows a practitioner to change direction quickly without heavy lunging steps. Instead of locking the elbows and wrists straight at the end of a strike, he taught students to snap the staff sharply on contact. This quick stop keeps the wooden bo from vibrating in your hands, driving the impact cleanly into the target while keeping you ready for the next movement.
Shimabuku later studied the kobudo system organized by Shinken Taira, but you can still feel a clear difference between Tokumine no Kun and forms like Shishi no Kun. While many classical weapons forms use wide circles to build up speed, Tokumine no Kun relies on short steps and direct body alignment to generate force. Picking up the bo today is not about playing the part of an old warrior or pretending we live in feudal times. Practicing with a staff simply shows you where your stance is off, where you are leaning, and where you are wasting energy, giving you a very honest tool to improve both your movement and your focus in training.
