About Aikido

The Nature and History of Aikido

The Japanese word Aikido is written with three characters which translate as "the way of spiritual harmony." Aikido is a budo or "martial way," evolved in the tradition of Japanese warrior arts, yet has a unique approach to self defense. Aikido is more than a martial science of strategy and tactics, it is a discipline for training the mind and spirit.

Aikido was developed by Morihei Ueshiba (1883-1969), known to Aikido students as O Sensei (Great Teacher). As a young man, he overcame debilitating childhood illnesses through martial arts practice, eventually becoming a master of the sword,the staff, the spear, and the art of ju-jitsu. O Sensei also held strong Shinto religious convictions concerning the ultimate futility of conflict and the illusory character of victory based on strength. This internal contradiction, which drove O Sensei to adopt a life of austerity and rigorous training, was resolved through an enlightenment experience which led to the development of Aikido, a martial art influenced by a philosophy of universal harmony.

Dynamics of Aikido

All Aikido techniques and movements are based on the idea of harmony. Aikido emphasizes blending with an attacker by moving in such a way as to neutralize the force of the attack itself and thus neutralize the attacker. This is done by using spherical movements which allow the Aikido student to deflect the attacker's energy while simultaneously entering close to the attacker; "to blend with the attack," and so neutralize it.

Properly executed, some techniques are spectacular, sending the opponent flying through the air. Others are more subtle: small deft movements that immobilize the aggressor. Both results are achieved not through the use of brute strength, but by blending and neutralizing the attack, followed by circular and flowing techniques to unsettle the opponent, and completing the movement with a throw or immobilization. Because great strength is not required, Aikido can be practiced by men and women of all ages.

Aikido Practice

Aikido training has also been shaped by its philosophy of harmony. There are no competitions or tournaments in Aikido. Rank is awarded through a testing procedure which emphasizes self-discipline, rather than the mastery of others. Daily practice focuses on the development of technical skills and awareness through the constant repetition of techniques in a controlled environment in order to master the fundamentals of moving, timing, and breathing.

Most practice is done with a partner: each working at his or her own level of ability, alternating as uke (the attacker) and nage (the one who is attacked). Both roles are stressed; each contributes skills that enhance overall sensitivity and control.

Wooden practice weapons — a sword (bokken), staff (jo) and knife (tanto) — are sometimes used in aikido training, not to understand how to use the weapon, but to better understand the techniques and movements of aikido itself.

Students train to neutralize the energy of the opponent's attack and to redirect and focus it into techniques of martial efficiency and power. At the same time, the student can use the same philosophy to deal with stress and conflict in daily life, and learn to remain calm under all conditions.


The final aim of Aikido is to integrate physical and mental training to develop a confident person who can think clearly and react instantly on and off the mat. It is only through constant training that an Aikidoist can acquire the habits of mind which make this integration possible.

In Aikido, such an integrated person is said to be "centered." A centered person displays a confident and relaxed posture, and centering gives Aikido movements their appearance of grace and simple elegance. Thus, Aikido training helps a student to become calm and centered and enables the student to deal with stress and aggression in an efficient and decisive manner on the mat, at home, at school, or at work.

How to Begin Practicing at Capital Aikikai

The best way to start training at Capital Aikikai is to show up! Aikido is a very open and inviting martial art. Previous martial arts experience is not required to begin practice, and at all levels, you'll find aikido practice to be quite social and cooperative. In aikido we practice with each other, not against each other.

If you are unfamiliar with aikido practice then you have a few options available to you to help you learn more. You can visit one of our classes and watch; you can join our beginners class; or you can practice in any of our general-level classes.

Visitors interested in learning more about training at Capital Aikikai are encouraged to stop by and watch a class. We kindly ask that new students show up 15-20 minutes before the scheduled class start time and introduce yourself to one of our members and complete a liability waiver form.

Please review the information given below to decide which approach you think is right for you.

Beginners Classes

We dedicate one class per week specifically for newer students. The focus of this class is learning the fundamentals of how to roll/fall safely ("ukemi"), the core stance ("hanmi") and footwork of aikido, and basic techniques and vocabulary.

The beginners class is a good place to start your journey with others who are also new to aikido. Senior students are there to work with you. After a few sessions in the beginners class you should feel ready to jump into the general practice at any of the other Capital Aikikai classes. Check the class schedule above for the day and time of the beginners class.

To attend the beginners class please show up about 15-20 minutes prior to the start time and introduce yourself to the instructor. Wear comfortable clothes for working out, e.g. full-length sweat pants and a T-shirt. No shorts or jewelry please. Changing rooms are available at the dojo.

Attending General Classes

You can start participating in any of Capital Aikikai's regular scheduled classes immediately. You may attend your first three classes, beginners or general, at no charge to see if aikido is right for you. To start practicing with us please show up 15-20 minutes prior to the scheduled start time and approach one of the students (before class begins), introduce yourself and sign a waiver. That's all! You can then take the class. You'll need to wear a dogi or a pair of sweat pants and T-shirt (no shorts or jewelry, please). Changing rooms and showers are available.

Classes are ongoing; new students simply begin attending the classes they prefer. Aikido training in general has no fixed curriculum. For your first few classes you will receive personalized instruction, generally from one of the dojo's advanced students. Very soon afterward you will be practicing with everyone else in the class as a regular student.

It helps to be in reasonable physical shape, but this is not a requirement. As you continue to practice, you will begin to achieve increased flexibility and balance, and better breathing.

There are no contracts or long-term fees at Capital Aikikai. New students are entitled to three free classes. After that, you would have to pay either a daily mat fee ($15 for each day you practice) or a monthly membership fee ($80 per month). If you plan to practice more than twice a week, the monthly rate will probably be more practical. You can pay online using our payments page.

Thinking of Beginning Aikido? Often-asked Questions
What is Aikido?

Aikido is a martial discipline for training the mind and spirit. Aikido does not stress competition, but emphasizes a win-win situation that helps develop a spirit of harmony and cooperation, mutual respect and consideration for others.

From a technical standpoint, Aikido is basically defensive and oriented towardrolling, joint locks, flowing movement and control of balance. It is not "rough," and in fact appears to be quite smooth and graceful to first-time visitors.

What is aikido training like? What can I expect?

Aikido is basically oriented toward rolling, joint locks, flowing movement and control of balance. Weapons training emphasizes the basic postures and stances that are a fundamental part of aikido.

When you visit or begin your training, you will learn the most basic — and important — things first: how to roll, how to stand properly, etc. As you progress you will begin to learn the fundamental movements from which techniques develop. During a typical class you will practice with a variety of partners, of all skill levels.

You do not need to be in excellent aerobic or muscular shape to practice aikido, but as you progress you will find youself becoming more healthy and fit.

When is Capital Aikikai open?

We are open and training seven days a week. Classes are held in the evenings during the week, and in the mornings during the weekend. Please click for our daily practice schedule.

Can I watch or try a class?

Yes! Visitors are always welcome to stop by and watch or take classes. If you would like to try a class, just show up about 20 minutes beforehand and ask one of the waiting students or instructors about taking a class. Generally, first-time students are given personal orientation and instruction by one of the dojo's yudansha (black-belt students). New students are welcome to any of the general classes. You do not have to call ahead or make other arrangements.

What type of people train in aikido?

All kinds of people train in aikido — men and women, young and old, even children. Because aikido is based on balance and circular movement, strength and size is not particularly important in training. In fact, women often have a natural affinity for aikido because, unlike men, they often do not have to unlearn forceful or muscular habits in their movement.

One unique feature of aikido training is the mixing of all skill levels.

Do I need special clothing or equipment?

If you want to try attending a class or two, simply bring loose-fitting clothing such as a T-shirt and sweat pants. Be sure to remove any watches, jewelry, etc. before stepping on the mat. The aikido "uniform" is a judo-style dogi, available either from us or from various area martial arts equipment suppliers, as are wooden practice weapons. Showers are available in both the men's and women's changing rooms.

Typically we train in bare feet, on a canvas-covered mat.

How much does it cost to train?

Those practicing regularly at the dojo are expected to pay monthly dues. New or prospective members may take three classes free of charge. There are no hidden fees, term limits or contracts.

Adult (Age 18 and up) $80
Student (Age 14+ and attending school) $50
