Erik Tracy

Rokudan – Muso Jikiden Eishin-ryu iaijutsu
Shodan – Shindo Muso-ryu jojutsu

Erik Tracy has been studying iaijutsu with Shimabukuro Sensei at the Jikishin-Kai since 1993. He first started a serious pursuit of martial arts later in life at the age of 33 when he saw iaijutsu was offered as a martial arts class at the University of California, San Diego.

"I was immediately drawn to the study of iai when I saw Shimabukuro Sensei demonstrate the intensity and grace of this art – it was something I knew I wanted to devote myself to."

Since then, Erik has continued his study of both iaijutsu and jojutsu at the Jikishin-Kai hombu dojo in San Diego where he is an assistant instructor.

Erik Tracy is an Engineer for a local defense company. He enjoys off-roading on his dirt bike, perfecting his BBQ skills, and is an avid Tolkien fan.

Chuck Arnold

Godan – Muso Jikiden Eishin-ryu iaijutsu
Shodan – Shindo Muso-ryu jojutsu

Chuck Arnold has studied under Masayuki Shimabukuro Hanshi since 1994, beginning his instruction in Muso Jikiden Eishin Ryu Iaijutsu at that time. Chuck has been instructing at the San Diego Hombu Dojo since 2003.

He is also a freelance illustrator, as well as an avid paintball player and motorcyclist.

He describes his study of martial arts this way:

"Life is always in a state of flux. Changes come and go, and the moments that we live are like waves upon a beach. If we live as if the sword and the spirit are the same, and that victory comes before the sword is drawn from the scabbard; then, before adversity comes and the need to express our spirit arrives, we are prepared and victorious whatever the outcome."




Scott Chang

Yondan – Muso Jikiden Eishin-ryu iaijutsu
Sandan – Kendo

In 1997, Scott Chang started training in iaido while still a student as UCSD. He was surprised that there was actually an extant martial art that dealt with Japanese swordsmanship. The next year, he found that kendo was also being offered at UCSD, and also began training.

Scott continued training in iaido, and after after several years, as one of the longest time students, he began assisting then instructor Erik Tracy with teaching duties, and eventually took over full instructor duties for the UCSD iaido class in 2002, under Shimabukuro sensei’s supervision.

One of the things that Scott likes about training iaido is that it represents training to overcome obstacles and better oneself. In the course of training, students develop better posture, positive attitude, confidence, and take responsibility to assist our juniors, seniors, and teachers. All of these are skills that allow us to become leaders, and contribute to our community.
