Hi, I’m June Encarnacion.


I remember when I was child, feeling uncertainty about beginning martial arts. I wondered if I had what it took to succeed and I wasn’t the most athletic or confident child - quite the opposite. Little did I know that beginning my martial arts journey would be one of the most profound experiences of my life!

When I opened my school in 2011, I made a commitment to serving and empowering the community of Bellevue by teaching children and adults the confidence, leadership and fitness skills that can only be achieved through martial arts.

Judo is the style of martial arts practiced by Seiei Dojo students.
The journey from White Belt to Black Belt is one of incremental learning and skill development, that students of any age and fitness level can embark on.

Judo, meaning "gentle way", is a modern martial art, combat and Olympic sport created in Japan in 1882 by Jigoro Kano. Its most prominent feature is its competitive element, where the objective is to either throw or takedown an opponent to the ground, immobilize or otherwise subdue an opponent with a pin, or force an opponent to submit with a joint lock or a choke.

Strikes and thrusts by hands and feet as well as weapons defenses are a part of judo, but only in pre-arranged forms (kata) and are not allowed in judo competition or free practice (randori). The worldwide spread of judo has led to the development of a number of offshoots such as Sambo and Brazilian jiu-jitsu. Judo practitioners are called judoka. The martial art of Judo is a great way to learn self-defense techniques, get a great workout, and lower everyday stress levels. 


One of the most fun parts of martial arts training is the ability to test your skills by competing in a tournament. Tournaments are not only fun for competitors, but they also become a great social experience for parents as well! In the last National Junior Judo Olympics, the biggest and toughest competition for the juniors, Seiei Dojo won a total of 32 medals with 19 golds, 7 silvers, and 6 bronzes.

From sparring to forms to team demos, these awesome competitions are not only a place where our students can test their skills, but also a place where team spirit is built, fears are overcome, and character is developed. Most importantly, they are tons of fun!

One more reason you will love martial arts at Seiei Dojo!
