What Is Kendō (Kendo)? A Japanese Martial Art Built on Respect
Kendō (commonly written kendo) is a traditional Japanese martial art in which two practitioners face off using bamboo swords called shinai.
The All Japan Kendo Federation (AJKF) defines kendō as "the way of human formation through the principles of the sword." Far from being a simple sport, kendō is a cultural practice that trains both mind and body through posture, etiquette, vocal expression, and timing — and it has spread around the world.
For international travelers fascinated by Japan, kendō is one of the cultural experiences most strongly associated with the image of bushi (warriors) and samurai.
That said, modern kendō is not a literal recreation of historical Japanese sword techniques but rather a martial art that emphasizes respect and concentration.
The origins of kendō trace back to the introduction of the Japanese sword. During the Edo period, Naganuma Shirōzaemon Kunisato and others established a training method using protective armor and bamboo swords (shinai), which is considered the direct ancestor of modern kendō.
The All Japan Kendo Federation was founded in 1952, and today the International Kendo Federation (FIK) has member countries and regions around the world, making kendō a truly global martial art.
Bowing before and after practice (keiko), respecting one's opponent, and handling equipment with care are all essential aspects of understanding kendō.
Equipment Used in Kendō: The Shinai and Bōgu
Kendō primarily uses two pieces of equipment: the shinai (bamboo sword) and the bōgu (protective armor).
A shinai is a practice sword made of four bamboo slats held together by a leather tip (sakigawa), a center binding (nakayui), a grip (tsuka), and a string (tsuru), and it serves as a substitute for a real sword.
Synthetic shinai approved by the All Japan Kendo Federation as alternatives to bamboo are also accepted as long as they meet official specifications.
Under AJKF regulations, the protective gear is collectively known as kendōgu and consists of four pieces: the men (helmet protecting the head), the dō (chest protector), the kote (gauntlets protecting the wrists and forearms), and the tare (waist protector).
These items provide essential safety while also creating the iconic look that defines kendō.
Practitioners wear a kendō uniform (keikogi) and hakama trousers, and they train barefoot.
At dōjōs and experience facilities, you'll often receive an explanation of how to handle the equipment at the start of the session.
Avoid touching shinai or bōgu without permission, leaving them carelessly on the floor, or stepping over them, and always follow the instructor's guidance.
The very act of treating the equipment with respect embodies the spirit of kendō.
What to Watch For in Kendō: Posture, Spirit, and Distance
When watching kendō, don't focus only on the speed of the strikes — pay attention to the moments before and after each exchange as well.
The posture taken during the stance, the distance from the opponent, the footwork (fumikomi), and the way each kiai (shout) is delivered all carry distinct meaning.
In kendō, practitioners shout out the name of the target — "Men!" "Kote!" "Dō!" — at the moment they strike.
This kiai not only demonstrates fighting spirit but also clearly expresses the intent behind each strike, and it factors into whether a strike is judged as a valid point (ippon).
A valid strike (yūkō datotsu) is defined as "a strike delivered with full spirit and proper posture, using the striking part of the shinai to hit the designated target with the correct edge alignment, followed by zanshin (continued mental and physical alertness)." The unity of spirit (ki), sword (ken), and body (tai) is essential.
Another captivating element to watch is the maai — the spatial and timing distance between opponents.
If the distance is too close or too far, strikes are unlikely to land cleanly, so practitioners constantly read each other's movements while searching for that perfect split-second opportunity.
Sensing the contrast between quiet, charged tension and the explosive intensity of the strike makes the appeal of kendō come alive.
Standard match time is 5 minutes, and matches are typically decided in a best-of-three format, with the first competitor to score 2 points within the time limit being declared the winner.
Essential Etiquette for a Kendō Experience
If you're trying kendō, listen carefully to the dōjō or instructor's guidance first.
The content, dress code, photography rules, and reservation requirements vary by venue.
Don't assume anything that hasn't been officially confirmed — always verify details on the official website or with the operator before applying.
Don't Forget to Bow
In kendō, there are designated moments for bowing: when entering the dōjō, when facing your opponent, and before and after practice.
There are several types of bows, including the shōmen no rei (bow toward the front of the dōjō, where a Shinto altar or honored space is located) and otagai no rei (mutual bow between practitioners and instructors).
Rather than treating these as mere formalities, view them as gestures of respect for both your opponent and the space.
Confirm Photo and Video Permissions in Advance
During kendō experiences and practice sessions, other participants may appear in the frame.
If you wish to take photos, always check with the venue or instructor first.
It's also a good idea to confirm the rules around social media posting.
Don't Push Yourself — Safety First
Kendō is a physically active experience.
You may feel disoriented by unfamiliar movements or loud shouting, but don't push yourself beyond what has been demonstrated.
If you feel any pain or discomfort, communicate it early.
Clothing and What to Bring
Most experience facilities rent out the kendō uniform, bōgu, and shinai. For maximum comfort, wear easy-to-move clothing such as a T-shirt and athletic pants, and bring socks, a change of underwear, a sweat towel, and water.
Since you may train barefoot, trimming your toenails short beforehand will help ensure safety.
How to Enjoy Kendō as a First-Time Spectator
If it's your first time watching kendō, don't worry about understanding every detailed judgment.
Start by observing the flow of "beginning with a bow and ending with a bow" — a fundamental principle of the art.
Beyond the moments of attack, the quiet tension before a strike (semeai, the mental clash) is also a defining element of kendō.
At venues and dōjōs, the basic rule is to watch quietly, matching the atmosphere of those around you.
If you're unsure when to clap or react, simply follow the lead of nearby spectators.
Pay attention to how the three referees — one chief referee and two assistants — raise their red and white flags.
When two or more flags are raised for the same target area, the strike is recognized as a valid point (ippon), marking a key moment in the match.
If a kendō practitioner or instructor is nearby, asking them about what to look for is also a great way to enrich your experience.
Even just memorizing the four target areas — men (head), kote (wrist), dō (torso), and tsuki (throat thrust) — will dramatically enhance your enjoyment as a spectator.
How to Experience Kendō During Your Trip: Tours for International Visitors
If you'd like to experience kendō culture during your trip to Japan, you can search for kendō experience programs designed for international visitors or for dōjōs that welcome observers.
Major cities such as Tokyo, Kyoto, Osaka, Yokohama, Sapporo, and Fukuoka offer English-language kendō experience tours, with some operators welcoming thousands of international participants each year.
Sessions typically last 1 to 2 hours and may include explanations of etiquette, basic shinai swinging, men strike practice, trying on the bōgu, and photo opportunities.
However, dōjōs are not primarily tourist facilities, so whether they accept observers or experience participants varies by location.
Before visiting, confirm the following points on the official website or with the operator.
- Whether observation or participation is accepted
- Whether reservations are required (most experience tours require online advance booking)
- Pricing (varies by plan, with some sessions ranging from a few thousand to over 10,000 yen)
- Whether there is a dress code or required items
- Whether photography or social media posting is allowed
- Supported languages and explanation methods (availability of English or multilingual guides)
Even simply watching kendō offers a window into one aspect of Japanese culture.
However, since kendō is a discipline that values etiquette, approach it with a learning mindset rather than treating it purely as a tourist activity.
Background Knowledge to Deepen Your Kendō Experience
Kendō vs. Other Japanese Martial Arts
In addition to kendō, Japanese martial arts include jūdō, karate, aikidō, kyūdō (Japanese archery), naginata, and iaidō.
Kendō is a one-on-one martial art centered on striking and etiquette, distinguished by its focus on free sparring rather than predetermined forms (kata).
Because the contrast between stillness and motion is so clear, kendō is often considered one of the most accessible martial arts for first-time spectators.
The Basic Flow of a Practice Session
A typical practice begins with seiza (formal sitting) and silent meditation (mokusō), followed by the shōmen no rei and otagai no rei. It then proceeds to suburi (basic swinging), kihon-uchi (basic strikes), uchikomi keiko (attack drills), and ji-geiko (free sparring), ending again with a bow.
Experience programs often follow a simplified version of this flow, so listening carefully to the introduction at the start will help everything proceed smoothly.
Conclusion: Discover Japanese Culture Through Kendō
Kendō is a traditional Japanese martial art that values not only the dynamic action of the shinai but also etiquette, posture, and concentration.
Even for beginners, simply learning the names of the shinai and the four pieces of kendōgu (men, kote, dō, and tare) along with the basic etiquette will make watching or trying kendō far more enjoyable.
If you plan to experience kendō during your trip, confirm the conditions, fees, and photography rules through official sources, and never forget to show respect to the dōjō and the other participants.
Through kendō, you can connect with the deeper Japanese cultural values of respecting others, honoring traditional forms, and embracing the principle of "beginning with a bow and ending with a bow."
