What Does "Rei" Mean?
The Japanese word Rei (礼) is often translated as "courtesy," "respect," or "etiquette." These ideas form an important part of traditional Japanese society and are deeply woven into the practice of Aikido.
Every bow performed in the dojo is an expression of Rei. It reminds us that martial arts are not simply about learning techniques—they are also about developing character.
Why Do Aikido Students Bow?
Bowing serves many purposes throughout a class.
Students bow when entering the dojo to acknowledge that they are entering a place of learning. Before training with a partner, both students bow to show mutual respect and appreciation for the opportunity to practice together. After completing the exercise, they bow again to thank one another for helping improve their skills.
The bow communicates something very simple:
"Thank you for training with me."
In many ways, it serves a purpose similar to a handshake in Western culture. While the physical gesture is different, the intention is remarkably similar.
Is Bowing a Form of Worship?
This question occasionally arises from people who come from cultures where bowing is associated with religious ceremonies.
In traditional Japanese culture, however, bowing is not an act of worship. It is a universally accepted social greeting used countless times each day by people of every background.
Japanese business professionals bow when greeting clients. Children bow to teachers. Customers bow to shopkeepers, and shopkeepers bow to customers. Friends bow when meeting and parting. These everyday interactions have nothing to do with religion. They simply demonstrate courtesy and respect.
The same principle applies inside an Aikido dojo.
Bowing to O-Sensei's Photograph
Many traditional Aikido dojos display a photograph of Aikido's founder, Morihei Ueshiba, often referred to as O-Sensei.
At the beginning and end of class, students may bow toward the photograph.
This is not an act of worship. Rather, it is a gesture of gratitude and respect toward the individual whose lifetime of study gave birth to the art we practice today.
Many schools and organizations throughout the world honor their founders in similar ways. Aikido simply preserves this Japanese tradition.
Different Types of Japanese Bows
Not every bow is the same. Japanese culture recognizes several levels of formality.
Eshaku (会釈)
A slight bow of approximately 15 degrees. This is commonly used as a casual greeting or acknowledgment.
Keirei (敬礼)
A bow of roughly 30 degrees. This is the standard respectful bow often seen in business settings and many dojo interactions.
Saikeirei (最敬礼)
The deepest bow, generally around 45 degrees or more. It expresses profound respect, heartfelt gratitude, or a sincere apology.
Although students are not expected to measure the angle of every bow, understanding these differences helps explain how Japanese culture communicates varying levels of respect.
Respect Creates a Safe Training Environment
Some people mistakenly believe etiquette is merely a collection of old traditions.
In reality, dojo etiquette serves a practical purpose.
When students treat one another with courtesy, they listen more carefully, communicate more effectively, and train with greater awareness. Mutual respect helps create an atmosphere where everyone—from the newest beginner to the most experienced instructor—can learn safely together.
Good etiquette also reminds students that their training partner is not an opponent to defeat but a person helping them improve.
Carrying Respect Beyond the Dojo
The lessons learned through Rei extend well beyond martial arts.
Showing respect, listening carefully, expressing gratitude, and treating others with courtesy are qualities that strengthen relationships at home, in the workplace, and throughout the community.
Many students discover that these lessons become just as valuable as the physical techniques they learn on the mat.

Final Thoughts
The Japanese bow is one of the simplest yet most meaningful traditions in Aikido. It reminds us that true martial arts are built upon respect, humility, gratitude, and mutual cooperation.
Far from being an act of worship, bowing is a universal expression of courtesy that has been part of Japanese culture for centuries. Understanding its meaning helps students appreciate not only the techniques of Aikido but also the values that have shaped the art from its very beginning.
By practicing Rei both inside and outside the dojo, students continue a tradition that encourages respect for others and continual personal growth.
