Bo and bojutsu in Mesa, Arizona, traditional Okinawan martial arts.

In addition to traditional rokubo (6-foot staff) there are many other similar Okinawa bo-weapons, such as han-bo (3-foot), jo (4-foot), ku-bo-tan (hand stick), nitan-bo (two sticks), eku (oar), bokken (wooden sword), kona-bo (club), nuntei-bo (a fishing tool), to name a few.

Rokubo: Of all of the kobudo weapons in the Shorin-Ryu arsenal, few are as traditional as bo (棒術). Bojutsu is a martial art that is part of all Shorin-Ryu styles with the exception of Shotokan. 

The tenbin is a pole that Asian farmers place across their shoulders in order to carry buckets at either end. Most are made of bamboo and measured by shaku (尺), which is a Japanese unit of 0.994 feet in length. The majority of bo used in Shorin-Ryu are roku shaku, or about 6-feet in length. 

Prior to 1961, shaku was a common unit of measurement. The unit was equivalent to the average length between mature bamboo nodes. But, there are >1,000 species of bamboo; each grows to different heights, diameters and lengths between nodes. Bamboo includes small annuals to giant perennial timber bamboo, some of which are the fastest growing woody grass plants on earth; known to grow 3 to 4 feet per day. Different species of bamboo vary from a few to 120 feet tall and have diameters as great as 12 inches (now that would be one heck of a bo). Bamboo has been around for some time and there are even species of bamboo preserved in the fossil record 30 to 40 million years ago. The Japanese kanji for bamboo is the ideograph (竹) which represent twigs of bamboo with leaves. 

A transporting tool, the roku-bo can easily be
converted to a weapon of self-defense.

The length of many ancient bo include hasshaku (7.96 feet) or hasshaku gosun (8.45 feet). Modern martial arts supply houses sell rokushaku-bo (6-foot bo). Confusion arises from another archaic unit that was also referred to as shaku. This third shaku was 14.9 inches, or the length of an average whale whisker (had no idea whales had whiskers). Anyway, it was adopted by law in Japan in 1881 for measuring cloth. To distinguish between the two common shaku, the cloth shaku was referred to as kujirajaka (kujira meaning whale) while the bamboo shaku was referred to as kanejaku. 

Okinawan karate practitioners train with bo, which is also a Japanese samurai weapon. A bo could out-reach katana (samurai sword). Unlike most Okinawan bo techniques which grasp the bo by splitting the pole into thirds, Japanese samurai grasped the bo near one end to achieve maximum reach. Many techniques that apply to samurai bo also apply to yari and naginata. When it comes to the shape of bo, most are familiar with maru-bo, or round staff. But there are kaku-bo (four-sided), rokkaku-bo (six-sided) and hakkaku-bo (eight-sided). There is even an archaic bo known as the konabo (also konsaibo and tetsubo) which looked more like a caveman’s version of a club studded with iron.

Bo kata of Seiyo Shorin-Ryu include Kihon Bo, Sho No Kun, Sho Ken No Kun, Suuji No Kun, Choun No Kun Dai, Choun No Kun Sho, Bojutsu Shodan, Bojutsu Nidan, Bojutsu Sandan. Note Okinawa bo is referred to as kon or kun in the Okinawa dialect.

Bojutsu - the martial art of Stick Fighting

For traditional karate & kobudo students, bōjutsu (棒術) is an important part of Okinawan Kobudo (古武道) as well as Japanese Koryu Budo (古流). It is considered to be an extension of martial arts.

Of all of the kobudo weapons in the Shorin-Ryu arsenal, few seem more traditional than bo. The bō is the weapon most people begin their kobudo training. The martial arts discipline of bo known as bojutsu includes distinct styles; however, bo is also part of the Shorin-Ryu styles. 

For more than 3 decades, Shorin-Ryu Karate & Kobudo was part of the curriculum in the Department of Physical Education, Department of Kinesiology, Department of Extended Studies, and University Club Sports at the University of Wyoming. The martial arts were one of the more popular classes and club activities on campus and often highlighted at various university events.

Kobudo was taught along with traditional karate by Professor of Budo Soke Hausel. It was relatively inexpensive martial arts weapon for students to purchase from local lumber or hardware stores: all that was needed was a 6-foot wooden dowel or closet rod. But most dowels are made of pine and can not be used safely for bunkai (practical practice): most snap when struck with force. Thus university students, staff and faculty were asked to purchase Oak or a similar hardwood dowel. On Okinawa, martial artists attain bo from backyards using kama or katana and cut a bo from a bamboo garden - but not in Laramie where temperatures periodically exceed -30oF in winters.

When the University of Wyoming Shorin-Ryu Karate & Kobudo Club began to expand in the 1990s, the club was recognized as one of the two top Juko Kai International associated schools in 1999 – which was not easy being that JKI is a large organization. There were nights when as many as 50+ students appeared in the Education Building Gym with 6-foot bo-staffs. In Physical Education classes in Corbett Gym, as many as 110 students attended class each semester. More would have attended, but 110 was the absolute cutoff limit due to space. This was an impressive showing of student interest, particularly when one compares the size of the University of Wyoming to other universities and community colleges. At the time, UW only had 10,000 students. As a comparison, Mesa Community College in Mesa, Arizona is more than double the size of UW.

It was a challenge keeping everyone in one piece in these classes; so Professor Hausel spaced the students with strict orders for no one to practice by themselves for fear that someone might accidentally walk into a bo. Everyone carried their bo in a vertical position held against the right (migi) shoulder. In this way, Professor Hausel was able to keep everyone safe from a rogue swing. The classes focused on basic strikes (uchi), blocks (uke), forms (kata), and a few applications (bunkai) on crowded kobudo nights, and all classes ended without a bo imprint on the side of anyone's head (atana). This went on for more than 3 decades as students, staff, faculty and the community were exposed to a large variety of traditional martial arts. Thousands of university and Wyoming community members participated in karate, kobudo, self-defense, jujutsu, samurai arts, women's self-defense, sorority, martial arts history, Christian, Institute of Religion, Chinese New Year and International Community classes, clinics, and demonstrations during this time. Professor Hausel brought the Okinawan martial arts to the University of Wyoming in 1977 and classes and clinics continued over the next 35 years. Professor Hausel donated time to teach most martial arts classes and clinics, and he had other duties on campus related to geological research and writing.

Professor Hausel was promoted to Soke in 1999. Only one person in any style of karate, jujutsu, aikido, judo, etc. ever reaches such a high level in martial arts. His martial arts activities and geological investigations were recognized by University presidents, Wyoming governors and National and International Halls of Fames. The martial arts group performed at many Men's and Women's UW basketball games. In one demonstration, the group finished with Soke Hausel breaking slabs of rock with his knuckles and head (he often joked that good martial artists are also good geologists and know how to pick rocks for breaking). At another demonstration, one of this Shihan (master instructor) performed a two-person bo-tonfa kata with him. During an early block, Soke broke the Shihan's bo with his tonfa. They finished the kata; but Soke noted it was a challenge to start with a bo and finish with hanbo. But it also emphasized why hardwood bo is used for karate training.

Historically, the bo was developed as a farming tool known as a tenbin or tenbinbo. These are still used in the Orient. The tenbin is a pole placed across the shoulders of a farmer to transport equal weights of material in buckets or sacks at either end. Most tenbin are made of bamboo due to availability of material. Any pole of suitable length could be used as a carrying pole or handle depending on the personal needs of a farmer. 

Nodes (shaku) are visible in the bamboo fence

The length of a bo varied depending on where in the Orient  it is made. The differences in length and diameter are due to a measuring unit known as shaku (尺). In China, shaku is known as chi and equals 1.094 feet (referred to as a Chinese foot). All around the Orient, different countries have different names for shaku and there is not much consistency other than being approximately the length of an English foot. In Japan, a shaku (Japanese foot) is 0.994 feet in length. 

In times past, longer shaku were used in Japan. The korai shaku equals 1.167 feet. Because of these differences, there remains an interpretation problem of historical records.

So why is there inconsistency in shaku? Prior to 1961, shaku was a common unit of measurement in Japan. The unit was derived from nature and equivalent to the average length between mature bamboo nodes. For those fascinated by bamboo, it should be obvious that the length between nodes will vary from plant to plant and between individual stocks in a single plant. But it is even more entertaining when one learns more facts about bamboo. There are >1,000 species of bamboo; each with different heights, diameters and even different lengths between nodes. The species includes small annuals to giant perennial timber bamboo. It is the fastest known growing woody grass plant in the world and has been reported to grow as much as 3 to 4 feet per day.



The different species of bamboo vary from a few feet to 120 feet tall with diameters as great as 12 inches (now that would produce one heck of a bo). There are many variables in bamboo. For those interested in paleontology, it is interesting to note that species of bamboo are identified in the fossil record 30 to 40 million years ago. As for kanji, the Japanese and Chinese use the ideograph "竹" to represent bamboo, which represents two twigs of bamboo with leaves. 

The length of bo produced in the past was known as hasshaku (7.96 feet) or hasshaku gosun (8.45 feet); both which are considerably longer than bo sold by martial arts supply houses. Supply houses sell rokushaku-bo that is 6 shaku in length. Supply house lengths are satisfactory for the needs of martial arts clubs; but for the purist, one might consider a hasshaku gosun bo from a bamboo plant (and cut their own). 

Confusion arises from another archaic unit that was known as shaku. This shaku was equal to 14.9 inches, or the length of an average whale’s whisker (I had no idea whales had whiskers). It was adopted by Japanese law in 1881 for measuring cloth. To distinguish between the two different Japanese shaku, the cloth shaku was referred to as kujirajaka (kujira meaning whale) while the bamboo shaku was referred to as kanejaku.

Not only did Okinawan Tode and Karate practitioners train with bo, the bo was also employed by Japanese samurai because of the considerable reach on a katana. Unlike most Okinawan bo techniques which grasp bo by splitting the bo in thirds, the Japanese samurai grasped the bo near one end to achieve maximum reach to stay out of reach from a samurai armed with katana (sword). Many techniques that apply to Samurai bo also apply to yari and naginata.

Some time ago, at a Juko Kai International kobujutsu clinic, members trained in samurai bojutsu arts at Scott Air Force Base near St. Louis. The hanger was filled with black belts ranging from 1st dan to 12th dan. Like most Shorin-Ryu systems, no one wore protective gear. It was every karate-ka for himself and herself. Attendees had to be on lookout for anyone near them as everyone and everything was fair game. Often people ended up defending against 2, 3, and sometimes 4 and 5 opponents at once. Talk about fun. Most people would think this would lead to serious injury, but all were well trained and love martial arts and the only injuries were bruises to fingers because of misplaced blocks. 



When it comes to the shape of bo, most are familiar with maru-bo, or a round staff. But there are also kaku-bo (four-sided), rokkaku-bo (six-sided) and hakkaku-bo (eight-sided). There is even an archaic bo known as the konabo (also konsaibo and tetsubo) which looked more like a caveman’s version of a club made from wood-studded with iron.

When training with bo, thrusting, swinging and striking waza resemble empty-hand karate techniques. Consequently, bōjutsu is often incorporated into the Shorin-Ryu styles of karate. Additional techniques taught with bo include entrapment techniques (waza) in which a practitioner blocks an attack while keeping both bo in contact to swing the attacker’s bo to a position causing the aggressor to lose balance. There is also techniques whereby  sand is picked up by bo and thrown at an opponent’s face, something that does not work well with dry (let alone wet) sand. 

The kata of the Seiyo Shorin-Ryu karate system include Kihon Bo, Sho No Kun, Sho Ken No Kun, Suuji No Kun, Choun No Kun Dai, Choun No Kun Sho, Bojutsu Shodan, Bojutsu Nidan, Bojutsu Sandan  and Bo-Katana No Kun. The last kata in the list is from Japanese Koryu Budo. Note Okinawans refer to the bo as kon and kun refers to bo kata.

Professor Hausel retired from the University of Wyoming and moved to the Phoenix Valley, where he still teaches every week of the year at the Arizona Hombu Karate Dojo in Mesa. Classes are available to adults and families. In the past, Soke Hausel taught martial arts not only at the University of Wyoming but also taught some classes at Arizona State University, University of New Mexico and the University of Utah.

Gilbert & Mesa Karate Students STICK with Kobudo

Whether training with Okinawan bo or kuwa (hoe) at the Hombu dojo,
 Arizona, adult and family karate students learn to use many traditional
(and some modern) kobudo and samurai weapons with their karate.

Karate and martial arts are more than kicking and punching. They are dynamic arts with a variety of disciplines. One discipline is known as bo or bojutsu and has been around for centuries and practiced in a martial arts school in the East Valley of Phoenix at the border of Chandler with Gilbert and Mesa, Arizona. Students in traditional Okinawa karate schools typically learn bo and other kobudo weapons. But only at a few schools can they also learn other Okinawa and Japanese martial arts, such as samurai weapons and modern weapons along with Shorin-Ryu karate training. At the Seiyo no Shorin-Ryu karate schools, students have the opportunity to learn many of these arts.

Imagine a stick. Imagine a 6-foot-long stick (6 shaku in length) with an Oriental carrying the stick across his shoulders and at each end is a suspended bucket. Now imagine that Oriental walking along a rice paddy dike when he is accosted by a tax collector from the Satsuma Samurai clan!

Can he defend himself? Does he have any weapons? If he has been training in Okinawan Shorin-Ryu Karate, he has weapons that include his hands, his transporting stick, referred to as a bo, and even the buckets. Training in Okinawan martial arts teaches use all of these as weapons including many other weapons in an ancient art known as kobudo.

To learn this traditional martial art in Chandler, Gilbert, Mesa, Phoenix, Tempe and Scottsdale, there is a traditional martial arts school in the East Valley of Phoenix that offer traditional martial arts weapons training and was located at the border of Gilbert with Mesa. The Seiyo no Shorin-Ryu Hombu dojo closed because of the loss of nearly 60% of its students due to the pandemic and masking by the CDC and Governor Ducey. With the loss of so many members, the organization could no longer meet the leasing requirements and closed its doors on March 1, 2021. However, they continue to train at non-commercial locations in Gilbert and Mesa, Arizona. For information, please contact Soke Hausel at sokeshodai@yahoo.com

Training in kobudo includes a variety of farming, fishing and merchant tools and implements used by the Okinawan
people in the past. One of the more common is that of the bo (6-foot staff). In our classes at the Arizona Hombu
and all Seiyo no Shorin-Ryu Karate Kobudo Kai schools, the students learn kobudo along with karate.  Much of the
 training involves basics, applications and forms. In this photo, students at the Arizona Hombu dojo are training in 
one of several kata (forms).

Mesa Karate Students Study Kobudo Weapons (bo)

At the Arizona Hombu martial arts school, Chandler, Gilbert, Mesa, Phoenix, Tempe and Apache Junction karate students train in kobudo weapons including bo at the international dojo on Baseline Road and MacDonald at the border of Mesa and Gilbert. The karate students are learning to use the bo. The bo is a common Okinawa weapon and farming implement used to carry material in the Orient by placing the stick over one's shoulders and balancing goods at both ends.

In times of trouble, merchants and farmers would take their bo and use it to fight off thugs and even  samurai. Students in the East Valley of Phoenix continue this tradition by learning Kihon (basics), Kata (forms), Bunkai (applications) and Kumite (sparring) with bo. They are taught by expert instructors in Karate and Kobudo.

The Arizona Martial Arts Students began training with the bo. The students must learn by rote and demonstrate several kata (forms) and self-defense applications certify in bo-jutsu. They are expected to learn 8 to 10 kata and all self-defense applications (bunkai) hidden in these forms (kata)

Bo (Staff) Martial Arts Weapons Taught in Chandler, Mesa and Gilbert, Arizona

Thursday evenings in many Traditional Martial Arts schools, in the world, as well as in the Phoenix Valley of Arizona, classes focus on kobudo (古武道) or martial arts weapons.

A variety of weapons arts are taught to students of Seiyo No Shorin-Ryu Karate Kobudo Kai (西洋少林流空手道) including bojutsu (棒術) where students learn the art of the bo (棒), known to many in North America as the staff. In the koryu (古流) schools of Okinawa, Japan, and North America, the staff is taught as a weapon rather than a twirling tool as is taught in most modern martial arts schools. 

Traditional martial artists learn kihon (基本) (basics) of the bo, kata (形) (forms) of the bo, bunkai (分解) (applications) of bo kata, and kumite (組手) (sparring) with the bo including ippon (one-step), sanbon (three-step), kiso (structured) and juyu (free sparring ) kumite. By doing so, these students become adapt in the bo as a weapon - exactly what it was intended for when not used as a farming implement.

In 2011-12, several students in the kobudo class at the Seiyo Shorin-Ryu Hombu became experts in tonfa and were certified in the weapons. They are currently working on sai with periodic review of bo, nunchaku, hanbo, kama, kuwa and manrikigusari.

Bo (棒), kon, bojutsu, bodo or 6-foot staff, is a well-known fighting martial art (budo [(武道]or bujutsu [武術]) that has roots going back many centuries. Being that the bo was (and still is) a common tool used for transportation of goods in the orient, it was a natural weapon of farmers and fishermen in the Orient. We often picture oriental farmers carrying goods at each end of a bamboo stick balanced over the farmer's shoulders - this was the bo.

Our students at the Seiyo Kai Hombu in Mesa, Chandler and Gilbert learn this martial arts weapon along with other kobudo weapons. Like most Shorin-Ryu karate styles, we place considerable emphasis on 'bo' or the 6-foot staff. We have 11 bo kata and out students also learn applications (bunkai) of the techniques in each kata and also bo kumite (sparring).

Several years ago, while training at Scott Air Force base under my sensei (Dai-Soke Sacharnoski), we trained with samurai weapons and ended with mass kumite: about 50 martial artists in an hanger fighting anyone who came near us. Sometimes we fought one on one, and periodically, it was one vs 2 or 3 individuals. It was great training.

At the Arizona Hombu in Mesa, we train in kobudo on Thursday evenings. In recent months, our students have been training in bo, katana, tonfa, hanbo, and sai.
