What Is Kendo and What Do You Need to Start Training?
Kendo is modern Japanese fencing: two practitioners face each other and score points by delivering disciplined, spirited strikes to defined target areas with a bamboo sword (shinai), while wearing protective armor (bogu). You can start with very little — most beginners borrow or rent gear from their dojo for the first few months — and the art is practiced both as a competitive sport and as a lifelong discipline with ranked progression. If you want a sword art built around live, full-contact sparring rather than solo forms, Kendo is the one to look at.
The core idea
A Kendo match is not a brawl. A strike only counts when it combines:
- Correct target — the designated valid areas (men/head, kote/wrist, do/torso, tsuki/throat).
- Correct posture and spirit — the strike is delivered from a proper stance, with full commitment and a shout (kiai).
- Correct follow-through — you remain alert and ready after the strike, not off-balance.
That combination is why Kendo is often described as a discipline first and a sport second. Two people can hit each other all day and score nothing if the strikes lack form or intent.
What you actually need to start
Beginners rarely buy everything at once. The usual path is to borrow a shinai and wear loose clothing until you've trained long enough to commit.
| Item | What it is | When you need it |
|---|---|---|
| Shinai | Bamboo practice sword, made of slats | Immediately — often borrowed at first |
| Gi and hakama | Training jacket and pleated trousers | Early; some dojos let beginners start in gym clothes |
| Bogu | Protective armor (men, kote, do, tare) | After several months, once basics are stable |
| Tenugui | Cloth worn under the helmet | With bogu |
The armor is the expensive part and the part you should not rush. Most instructors want to see that you can move, hold posture, and strike safely before you're put in bogu and start taking contact.
How Kendo differs from related sword arts
These arts share a lineage and are often confused, so it helps to separate them by what you actually do in a session:
- Kendo — sparring with a shinai and bogu against a live opponent. Sport and discipline combined.
- Iaido — solo forms drawing and cutting with a real or practice blade (iai). Emphasis on precision, not contact.
- Iaijutsu — the older combative drawing-and-cutting techniques that Iaido's forms descend from; more martial, less sport.
- Kenjutsu — classical swordsmanship, often paired forms with wooden swords (bokuto), predating modern Kendo.
If your goal is competition and full-contact practice, choose Kendo. If your goal is solo precision and drawing technique, Iaido or Iaijutsu is the better fit.
Ranked progression
Kendo uses a kyu/dan ranking system, and progression is tied to both technical skill and time in practice. Beginners typically start at the lowest kyu ranks and test upward. Because rank reflects demonstrated ability rather than purchased status, expect your first grading to come only after consistent training — not on day one.
Practical notes before you commit
- Find a dojo first, buy gear second. Instructors know what fits their style and can often lend or point you to the right shinai length and bogu size.
- Expect the first months to be footwork and basics. Striking comes later; this is normal and not a sign you're behind.
- Ask about borrowing. Many clubs keep loaner shinai and even bogu for new members, which keeps your initial cost low.
If you're comparing Kendo against Iaido, Iaijutsu, or Kenjutsu, the deciding question is simple: do you want to face a live opponent and spar, or do you want solo form and precision work? Kendo is the former.
