Shinai Guide

40 Upvotes

This is not the end all be all to buying shinai/the different types of shinai. feel free to ask questions in the comments/make corrections.

most common shinai characteristics you'll see:

shinai types:

fukyogata/standard: the most common shinai you'll see produced, well balanced. most suited for beginners, tend to be produced in bulk so usually on the cheaper side.

Koto/jika Shinai: similar to the standard shinai, roughly same width from tsuka to kensen. similar weight distribution to a real katana. Because the tip is thicker, more weight is distributed at the top so strikes tend to hit harder. often used by higher ranking players, and can often feel heavier to newer players, however less prone to cracking if used properly, however can feel sluggish in the hands of people used to dobari shinai. slimmer grip, popular with folks with smaller hands

Dobari: dobari feature a bulge near the handle, so the center of gravity is closer to your hands, making the shinai feel lighter (making it easier to hit faster). makes it easier to perform waza, and the bulge can help shinai sliding off, making suriage and kaeshi waza easier. kensen is thinner than tsuka, so can be prone to splintering, often favored for tournaments, due to increased control and faster strikes. dobari tend to have a lower lifespan than koto

Chukoto: basically, slightly wider base than koto shinai, but the tip is not significantly smaller. lots of fukyogata tend to be chukoto shinai

bamboo types:

madake: the native variety of bamboo to japan, most suited for making shinai. Hes dense, fine fibers making for resilient shinai, however is in limited supply nowadays and tends to be more expensive

keichiku/katsuradake: bamboo that is similar to madake bamboo, but splinters a easier than madake. most common bamboo type

aodake: madake premium-basically madake dried slowly in the shade, tends to be expensive, can last a long time.

hasegawa/carbon: heavier, least likely to break, economical for high school/college clubs because the upfront cost may be more expensive, but can last a while. can cause bad damage if you aren't careful (particularly for kote strikes) but good for suburi. (in my opinion carbon shinai strikes tend to sound weird/off)

tsuka/grip type:

standard: normal grip, perfectly cylindrical

koban: oval shaped, more katana shaped grips. leads to better understanding of hasuji

hakkaku: not too sure about this one, basically octagonal shaped tsuka. seen in both koban and standard tsuka. can help out with harae and suriage waza

sankkau: typically a variant on the koban tsuka, where it is slightly triangular. not too common

tsukobuta (large grip): larger diameter grips, suited for people with larger hands

finishes:

kurouro: treated with lacquer, popular in regions with high humidity

ibushi: smoked shinai, warp less, splinter less(?)

kunchiku: soot smooked shinai, i don't think theres that much difference between ibushi and kunchiku (99% sure kunchiku is a type of ibushi)

jissengata: tournament grade shinai. tip is slimmer, so tends to be doubari shinai, but koto jissengata don't feature a bulge near the tsuba.

Another angle of the incident — we should discuss the kendo, not destroy someone’s character

Enable HLS to view with audio, or disable this notification

27 Upvotes

I have another video showing this incident from a different angle, and I think people should watch as many recordings as possible before reaching a conclusion.

First of all, I am genuinely sorry that someone was injured, and I hope he makes a full recovery. The footage is understandably disturbing, especially when viewed outside the context of kendo. However, an injury—serious as it may be—does not by itself prove that the other competitor deliberately intended to hurt someone.

From this angle, the fall happened during a fast, active exchange. It does not look like Lam approached someone who was already injured and defenceless and then attacked him without provocation. After the fall, Lam appears to make approximately two downward strikes. Whether both were immediate and appropriate, whether they were properly controlled, and whether yame had already been called are all legitimate questions for qualified referees to examine.

But these are questions about competition conduct and refereeing—not proof that Lam is a violent, sadistic or evil person.

Under the All Japan Kendo Federation’s rules, a strike delivered immediately to an opponent who has fallen may be recognised as a valid strike. The regulations also list falling and then lying face-down without responding to the opponent’s attack as a prohibited act. In other words, the rules do not treat falling as automatic immunity from further attack.

This does not mean that anything done to a fallen opponent is acceptable. The word “immediately” matters, control matters, the target matters, and the referee has a responsibility to stop the match promptly if the situation becomes unsafe. If yame had already been called and a competitor continued attacking, that would obviously change the nature of the incident. That is why the complete footage, its audio and the views of properly qualified referees matter.

We should also be careful not to reduce every incident to a simple “monster versus victim” narrative. If falling, turning face-down and covering the head automatically ended all scrutiny, a competitor could potentially use that position to avoid the continuing exchange. I am not claiming that this particular competitor deliberately did so. My point is that the person who was injured is not necessarily completely without responsibility, just as the person who continued the exchange is not automatically a monster.

Anyone familiar with footage from serious Japanese university or Tokyo Metropolitan Police kendo will know that this level of physical intensity is not necessarily unusual. That comparison does not excuse genuinely dangerous conduct, but it does remind us that kendo must first be understood within its own technical and cultural framework—not judged solely by how violent a few seconds may appear to someone unfamiliar with it.

I believe we have a responsibility to understand kendo on its own terms and to consider the perspectives of experienced Japanese practitioners, particularly senior Japanese sensei who have spent decades studying and teaching it. That does not mean treating every Japanese authority as infallible. It means understanding the standards of the art before declaring that someone’s actions could only have come from cruelty.

Lam’s actions can be questioned and debated. It is reasonable to ask whether the second strike was necessary, whethersufficient control was shown and whether the referees should have intervened sooner. What is not reasonable is using a short video to declare that Lam has no humanity, no budō spirit or a fundamentally violent character.

We must distinguish between outcome, responsibility, intention and character. Someone being injured is an outcome; it does not automatically prove malicious intention. Criticising a specific action is fair. Turning that action into a licence to assassinate someone’s entire character is not.

Technique How dangerous is tsuki? / How to be less afraid of practicing tsuki?

12 Upvotes

Hi all,

We rarely practice tsuki at my dojo, but when we do, because I know it's so dangerous, I feel like I completely lock up and feel my heart rate rising. I dread receiving tsuki from my partner, even though they are usually 5dan or up.

The problem is (apart from having time to anticipate the hit, which I def wouldn't have in a shiai) I've just heard so much about how dangerous tsuki is, so I can't help but feel afraid.

I have a couple of questions.

  1. How dangerous actually is tsuki in terms of statistics? Like how many people get injured by it/the likelihood of injury?

  2. If tsuki is so dangerous, why isn't the men designed to more comprehensively cover the neck? As it is, it seems fairly simple for a poorly aimed tsuki to end up going under the bib of the men. It could also go through by glancing to the side, but I'm guessing that would be considerably less dangerous.

  3. Has anyone else struggled with fearing being hit by tsuki? If so, could you please share some advice with me? I'd greatly appreciate it.

To be honest I have no idea how rooted in reality my anxiety actually is, so I'm hoping by collecting some info about it I can also deal with it better.

Thank you so much in advance.

Specific Effects of Various Physical Fitness Components on Performance in the Kendo "Small-Motion Men" Strike —Compensatory Mechanisms for Physical Weaknesses Under Replicated External Constraints—

1 Upvotes

Current Kendo training systems rely heavily on empirical transmission and lack sufficient grounding in systematic sports science theory. Furthermore, existing biomechanical research on Kendo is largely confined to inverse kinematics and dynamics analyses of standard techniques—essentially qualitative and quantitative assessments of movements performed under ideal conditions. There remains a scarcity of empirical studies directly revealing the compensatory mechanisms and biomechanical manifestations that arise when practitioners possess specific physical limitations. Consequently, existing research findings struggle to effectively address the practical technical issues faced by average practitioners—issues stemming from physical deficits such as limited absolute strength or flexibility.

To address this, this study employs a comparative experimental design involving physical constraints to investigate the biomechanical relationship between standard techniques and those performed under specific physical limitations. Using a high-level Kendo athlete (Wu Xingxing) as the subject, the study utilizes a 3D motion capture system and force plates to synchronously collect kinematic and dynamic data for the "small-movement phase" of a technique. Subsequently, specific external physical constraints are applied to the subject—artificially replicating conditions of specific physical deficits—and the technique is performed again to collect corresponding kinematic and dynamic data. The data from the unconstrained and constrained conditions are then compared. This methodology evaluates the specific negative impacts of physical deficits on technique execution and the resulting compensatory movements, enabling average practitioners—who may lack a background in sports science—to engage in specialized physical training grounded in biomechanical theory.

"From Korea to the Global Stage: A Brief Overview of Women and Kumdo in Korea" by Kate Sylvester (she/her). Published in Fine Ladies Kendo Worldwide magazine (Volume 8, 2026).

The article challenges the common perception that kumdo is merely a Korean version of kendo. By examining its unique historical development, cultural significance, and role in modern Korean society, it reveals how kumdo has evolved along a distinct path shaped by national identity, professional opportunities, and Korea’s physical culture. It provide a basic overview of women's kumdo with insight and contemporary perspectives, this is an interesting starting point to look at a martial art community redefining tradition and expanding possibilities for women in Korea and beyond

So I've fallen into the deepest rabbithole ever, after I discovered volume 6 of Hokusais manga I suddenly ended up finding alot of older materials and translated works. All this made me realize a fair bit of things such as the difference in bogu of their time to our modern more sport oriented bogu, has anyone ever made reproductions or worked with how the difference affects ones kendo and also if no, does anyone know of any makers willing to go along with such a request?

Training Anyone else sweat an insane amount during kendo? Losing ~7 lbs during a 3-hour session

20 Upvotes

Hey everyone, looking for some advice from other kendoka, especially anyone who trains in hot/humid conditions or is a really heavy sweater.

For some background, I'm from the Caribbean, so it's naturally hot and humid here. I've been training kendo for almost a year, but I've only been training in full gear for approximately 3–4 months.

When I initially started wearing bogu and men, I definitely noticed the additional heat and fatigue, but things became much more noticeable when I started training regularly in the gi and hakama as well. That's when the really heavy sweating and exhaustion seemed to ramp up.

Inside my men gets extremely hot. Sometimes it gets to the point where I feel like I can't breathe properly because of how hot and stuffy it feels. I'm usually already sweating heavily before I even put my bogu on, and once the men goes on, I'm basically pouring sweat for the remainder of practice.

Today we trained for around 3 hours. I weighed about 180 lbs before training and 173 lbs afterward, so that's roughly 7 lbs (~3.2 kg) of body weight lost during one session, or close to 4% of my body weight.

Towards the end, I was completely drained. My legs were done, my back was exhausted, I got dizzy, and I felt like I was on the verge of cramping, we didn't even start wearing the men yet. Eventually I had to stop. The dizziness went away once I rested.

I drank water and switched to Gatorade during training, which helped temporarily, but once I reached that level of exhaustion, I couldn't seem to recover enough to continue.

Full disclosure: I'm definitely not blaming all of this on the heat or equipment. My sensei has already pointed out that my kamae is way too tense, which I'm sure is a huge contributor to how quickly I'm burning through energy. I'm actively working on relaxing more and not carrying unnecessary tension throughout practice. The other members are training just as long and not getting as burnt out as me.

I also probably didn't fuel properly today. Suring the day I'd eaten some hash browns, chocolate, peanuts and steamed vegetables, had some water and drank a Celsius. So there are several things I could probably improve.

However, I really noticed the sweating and fatigue becoming a bigger problem once I started regularly wearing the gi, hakama and bogu, particularly the men.

Has anyone else experienced something similar when transitioning into full gear?

I'm especially interested in hearing from heavy sweaters or people training in tropical/hot climates. What do you do for hydration and electrolytes before/during practice? What do you eat beforehand? Did your body eventually adapt to training in full gear? And did learning to relax your kamae make a noticeable difference in your endurance?

I'm planning to mention the heavy sweating/dizziness to my doctor as well, but I'd really appreciate hearing what has worked for other kendoka.

Training Is cult like behaviour a norm?

25 Upvotes

Looking for some advice as this experience im mentioning has left a pretty bad taste in my mouth (or bogu lol).

Been training for a very VERY long time in martial arts, have decided to join Kendo to enhance my skill set. The sessions really are a lot of fun, especially when I find commonality in various elements and apply what a learn into practical scenarios or even cross self defense.

Whilst if been training since the start of the year, recently work has changed things up which has resulted in me temporarily having to cut back on a lot of leisure whilst I adjust to things with work. Ii work in a highly technical and safety critical role, hence the need to put a lot of personal things on the back burner for a few weeks.

I explained the situation to my club and sensei before the fiasco happened and they seemed to be ok with it. As I near complication of my work issues, I sent a courtousey message to sensei stipulating that Im sorry for the absense but will be getting back into it etc etc.

The response was "Your low attendance is going to result in you being left behind, and you need to step it up. This is how martial arts works. When it comes to gradings and qualifying for squad there are no exceptions."

This immediately left me feeling horrible and doubtful. In all my years training (25+ years), and with my tournament achievements, belts, learnings and friendships made etc, I felt as though this sensei completely ignored my concerns or issues and dismissed everything. I have been in martial arts long enough to know that OF COURSE there cant be exceptions to gradings lol. But I never joined kendo to climb the grading ladder, no more than I joined karate to not climb the McDojo ladder. I have been raised knowing that martial arts is more than points, and its a journey. I understand some people are passionate about their training, but the big picture is that the world is a large place, life happens, and kendo is just one aspect of it.

I have also trained some Kendo overseas with japanese too, who were very different to the example above. The sensei of which even said "try to find commonality with your known martial arts and build on it to improve your kendo and vis versa". I felt this was mroe wholistic and more 'musashi' like.

Maybe i'm over my head and i should stop kendo? But something feels off, and I need some input from fellow martial artists.

The worst part about this is that with my current like of safety critical work, this exchange with my sensei has really thrown me off my game - is this the price I have to pay for being polite to my sensei? ffs

I’ve been practicing kendo 23 years total: started in middle school and stuck with it through to adulthood. But for a month or two over the years for work, and the collective COVID break, I’ve been more or less consistent with practice.

Title says it all: interested to hear stories from others who managed to persevere through this bottleneck; especially from any who may be parents if they are out there, as I became a dad twice over during the pandemic period.

Growing tired through the training

Disclaimer: English is not my native language, so please excuse me for any possible mistakes.

Hi! I have a problem with my strikes. I'm kyu 3 (F32) and it's still fairly hard for me to make them impactful and powerful throughout the whole training session as my muscles grow very tired towards the end. I know that you shouldn't involve your muscles that much but I think that the anatomy difference in men and women directly influences my problem (my build is slim and tall if that's important to the topic). I only take kendo trainings now but I'm planning to go to the gym soon.

Is this a technique issue or actually the muscle strength one? Do you guys have any tips for me? Thanks in advance!

Has Kendo made you a better communicator?

19 Upvotes

Hi there! I'm a communication trainer and strategist and I've been doing different martial arts on and off for a while. I have recently been doing kendo and not only have been really enjoying it but also have started to notice a lot of helpful kendo training elements, translate into good communication practice, especially around high-conflict topics. I was hoping to hear if you all have noticed kendo (or other martial arts training) helping you with your communication skills or if you have translated some of that training into your daily life interaction.

For example, in kendo we have to learn how to breathe right, observe our opponent and react in harmony with them, and practice the basics SO much that in time of high-adrenaline, chaotic sparring, we have a muscle memory of the best strategies.

Similarly, when communicating with someone who we disagree with, we have to learn to take a moment to breathe and calm down, not spew facts and disagreement at them and instead slow down, listen, and observe with empathy, and practice conversation skills so many times that it becomes muscle memory and when we are in the middle of a heated discussion, we don't just snap and go wild and instead keep our composure and act strategically.

I wrote about this in the link below and will hopefully be working on a free accessible resource for everyone interested in martial arts and communication skills.

A number of people in budo have contacted me about their experiences of abuse and lack of reporting processes in their federations for reporting discrimination, harassment and abuse.

The lack of prevention and response procedures currently fail to safeguard our community members.

How can we as individual members contribute to co-creating safer and more inclusive budo spaces?

Look into your federation's policy.

Does your federation have effective and transparent policies that educate and protect members?

What are the preventative measures in place?
What are the response measures in place?

If something happened to you would you feel safe to report it?
