The Martial Arts Instructors of Japan

Nothing can replicate training in Japan; the immersion in the Japanese culture, the amount of training one squeezes into a trip, the practitioners your surrounded by – a few days changes your movement forever. The most important part of training in Japan is the opportunity to train under the best instructors in the world and Soke Hatsumi himself.

For all of us – Soke is the goal; we are all trying to understand and to grasp how Soke moves. And each of the Sensei in Japan attempt to breakdown his movement into terms the rest of us can understand. At the same time though, each of the Sensei take the principles of Soke and make it their own. It’s a bit like two different painters looking at the same scenery and then painting it to make their own – both paintings can be accurate, and beautiful, but they both can be unique. This is how martial arts work as well; while the principles are the same the movement becomes unique to the practitioner.

Depending on what you’re working on, you may gravitate towards one teacher more than another – just as you may prefer one painter’s style over another. I would caution though not too simply “pick one”; each of the teachers have their strengths and focus that is important – and to not train under one would be to rob yourself of potential insight.

So the question becomes – who to train under? What are the insights each teacher offers? Here is an opinion on the different teachers, and what makes each one unique and valuable. This is only an opinion, and as I learn more and gain understanding, my opinion may change – but at a minimum this can give you a starting point if you never have trained in Japan and may help you find something that the teacher offers.

Let’s start with the Grandmaster himself – Soke Masaaki Hatsumi:

Hatsumi Sensei

The leader of the Bujinkan and the person we can thank for bringing the art to us is Soke Masaaki Hatsumi. I won’t pretend to grasp the lessons of Soke’s classes, but I think I may understand what he’s doing. Soke is always teaching to the Shihan, the highest level practitioners. This makes it difficult for the rest of us who aren’t quite ready for those lessons – like someone who has studied high-school physics sitting in on a lecture by Stephen Hawkings on String Theory. Yet, there are valuable lessons – that if you pay attention – you can grasp.

What Soke is teaching are not techniques, but rather ideas – a philosophy rather than a kata. This is why he talks about feeling; he wants us to recreate the feeling of a movement, not necessarily the movement itself. There is one caveat to this however; we have to go through all those kata and learned proper technique before we can begin to understand the principles within it, and start to play with his ideas.

Soke also has a devilishly funny – and sometimes even a bit dirty – sense of humor. You can tell that he truly enjoys teaching and sharing the art. This might be why after he demonstrates something, he always finishes with “hai okay play”.

An Aside

If you do get the opportunity to take a class with Soke, you will be pleasantly surprised to find out that in addition to being an amazing martial artist, Soke is also a very talented calligraphy artist. In fact if you bring a piece of paper Soke will draw something for you at the break in class. A word of warning though – Soke has a sense of humor, so if you try to get too clever, or just ask for anything – you might end up with a dirty picture (which is pretty awesome in and of itself).


Hatsumi Sensei has retired from teaching and has passed on Sokeship of each of the schools. He still remains the leader of the Bujinkan overall.

Ishizuka Sensei

Ishizuka Sensei is one of the “first generation” of Japanese students of Soke. It’s only been recently that he has become better known in the Bujinkan community for the most recent generation. However, he has played a pivotal role in training many that have become the rest of the teachers we study under.

Ishizuka is nothing short of impressive; his movement is precise and fluid, powerful yet relaxed. He is very much a traditionalist – emphasizing proper kihon and technique. His style of teaching often involves the most senior student demonstrating a specific technique from a Ryuha, and then making small corrections in it’s execution. It’s then up to the rest of the class to drill the form.

The training is his relatively small dojo is intense – but satisfying. The particular type of students he attracts are eager to drill the basics to truly learn the proper form. And his vast experience and willingness to teach it leave your technique and movement more polished.

Just training a handful of times at his dojo, I can see connections between the proper kihon and pretty much everything else being taught by Soke and the other Shihan. It feels like connecting to some root from which everything springs.

A Cool Character

Ishizuka is also just very cool – maybe because he is also a Jazz musician. The way he speaks combined with his relatively deeper voice hints at a balance between seriousness and playfulness. If you get invited to his class though, you better pay attention to how things are done. He will often go around watching students practice, and when he sees you do something he doesn’t like, he’ll immediately ask you “why are you doing it that way?” This is a rhetorical question of course. Then he might use you as an uke – or at least just do a technique on you: “A good experience…” he might say. While a bit nerve racking it helps to know he’s more than willing to correct mistakes he sees, and do it with a cool confidence that only a Jazz musician can.


Ishizuka Sensei was made Soke of Gyokko Ryu Koshijutsu.

Seno Sensei

Seno is also a first generation student. His classes are probably the most frustrating on the first go around due to their precision and subtlety. Often only 3 to 4 techniques or forms are taught, and then the next 30+ minutes involves trying to figure out what and how he did what he did (and a lot of head scratching). You’ll soon realize that Seno is operating on a whole other level of subtlety and precision that is challenging to deconstruct. A few degrees of angle, a change of a few inches of foot placement, and suddenly the technique works flawlessly.

If he sees you struggling however, he’ll come over and give you hands on correction to help you find the hidden details; often this will involve him grabbing your belt and literally walking you through step by step of the technique. You wouldn’t think that someone this detail oriented would be as friendly as he is. But whenever he shows something, or is just interacting with you, there is always this air of humility and warmth to his presence.


A Demonstration of Skill

During the filming of the NHK World production of “Last Living Ninja”, a few of the Shihan were asked to demonstrate Omote Gyaku (and/or a henka of it). I had trained enough with most of them to have a general idea of how they moved – and they didn’t disappoint: each one was unique and amazing. Then it was Seno’s turn. I hadn’t trained enough with him to be able to imagine how it would look, so I was very curious to see his movement at speed.

What I ended up seeing was the kihon omote gyaku executed with fluidity and precision that resulted in his uke flying through the air. It was like seeing a true Omote Gyaku for the first time – I suddenly understood how it’s supposed to look in a fight with just the right timing, distance and precision. My jaw hit the floor. For all his humility Seno is nothing short of a bad ass.


Unfortunately Seno Sensei passed away in 2019. He is sorely missed.

Noguchi Sensei

Noguchi Sensei’s classes are maybe the most exhausting, but also the most “playful”. Noguchi Sensei’s movement is all about manipulation – he plays within the space to manipulate the reaction of the opponent. As this is happening, he is twisting your spine and locking you off balance. It borders on magic: he can make you miss a punch with the movement of a hand as if it were a Jedi mind trick.

In his class it’s mind overload; there is technique after technique and variation after variation. We once counted the number of things he showed, and we lost count after 80! Yet, it’s also fun – there is always some laughter from both humor and surprise when he is showing a technique. His playful attitude and joy in teaching will keep you engaged. He also will walk around the class and show each group something – giving insight into a small detail you might have missed. And when he does, there is always a smile and a laugh – all without saying a word in English.

His classes feel the most like Soke’s in the format and speed in which you move on from one technique to the next. And all the things he shows – manipulating the opponent – you can see Soke doing as well in class. It’s as much mental as it is physical.

A Feeling

When it came time to take the Godan test I was lucky enough to be tested by one of the Japanese Shihan – Noguchi Sensei. At the moment of the test, I can truly say I felt his intention when I rolled out of the way of the swinging sword. But it was a bit different than I expected: it felt like we were working together at the same time. I thought about how he likes to use dancing as a metaphor in his classes, and it did feel like a dance with him leading. He immediately came over and gave a warm smile and shook my hand as I sat in shock that I somehow passed. It’s a day I will never forget, and I thank him and Shiraishi Sensei for the opportunity.


Noguchi Sensei has been named the Soke of Koto Ryu Koppojutsu.

Nagato Sensei

Arguably the most physically intimidating of the Shihan, Nagato Sensei has possibly the most fighting experience of the Japanese Shihan – as a former Judo teacher and Kickboxing Champion. However, he would say that his former training simply gave him bad habits he had to unlearn. He also has a very good sense of humor, and often will slip in a humorous comment here and there. While he takes the training seriously, and expects the students to the move correctly, he also has a very personable manner.

Nagato Sensei’s movement is remarkable in that he focuses on how to safely enter a technique. When initiating a technique, he is able to cover from just about any secondary attack, almost as if he is constantly setting a trap and waiting to see if the opponent takes the bait. A lot of his movements utilize distance to draw the attack out – throwing off the opponent’s balance, which aids in this method. This is often characterized by his method of recieving as if you were catching a ball: “if you can catch a baseball, you can catch a punch”.

Soke also does this in his techniques as well; in any technique he has already prepared for a subsequent attack and can move freely within the space safely. Interestingly enough, both Soke and Nagato Sensei have somewhat similar Martial Arts backgrounds prior to studying Ninpo.

An Experience

When you take a class, there is a certain honor in being the uke (the partner) for the teacher – it’s a privilege. It’ also a rare opportunity to experience what it’s truly like when someone of such a high caliber performs a technique on you. It demands your focus and attention. I had such an opportunity with Nagato Sensei.

It’s hard to explain what it felt like; it was almost like being in a cage with a lion. It was truly intimidating. I was surprised at how gentle he was when applying techniques – and surprised at how quickly he could inflict pain with ease. After he demonstrated a technique – I couldn’t remember what he did, and would go back to my training partner and say “okay what just happened”. My brain was in survival mode at that point.

For fun, he then used me to demonstrate the proper way to punch a chin; he kept saying “not like this, but like this” giving me a punch while my arms were wrapped up. It wasn’t hard like he was hurting me or trying to knock me out – he was just testing me a bit as well as having a little fun. Afterwards, we took a picture together and shared a laugh when I asked if I could take a “funny one with him”. However, I promised him I wouldn’t publicly display it. And one thing is for sure: when you make a promise to Nagato Sensei – you keep it.


Nagato Sensei was named the Soke of Shinden Fudo Ryu Dakentaijutsu.

Shiraishi Sensei

Shiraishi Sensei is called “the Smiling Demon”; no matter what – he always has a smile on his face. Most western students traveling to Japan will notice – and appreciate – that he teaches his classes in both English and Japanese. You’ll also notice that he is often used as uke in Soke’s classes, and you can sense the deep respect and admiration he has for Soke.

Shiraishi Sensei is all about principle and balance. This is characterized by his method of “foot work, spine work, hand work”, where there’s always a shifting of balance onto one foot before moving the other. There is also a rotation of the hips as you shift your balance, lending to the “spinework” aspect of movement.

Not only is this movement extremely stable, but it’s also very sneaky – it’s hard for the opponent to sense where your moving as you confuse their balance. You can also see Soke using this movement if you watch his feet, although it’s extremely hard to catch since Soke performs it so subtly. As Shirashi Sensei would say “good foundation training this makes”.

An Honor

Shiraishi Sensei is the Shihan that recommended me for my Godan – an honor that I hope to live up to. The day of the test, he was gracious enough to be my training partner for Soke’s class: “relaxing training for your test” he said. Of course, it wasn’t as relaxing as it was exhausting, for the simple fact that I wanted to do my best so he could enjoy the class as well (it’s not every day you get to train with a Sensei). By far it was one of the most rewarding classes I’ve had, since Shiraishi Sensei helped point out what I would normally miss in Soke’s movements – it was eye opening. For the whole story about that, you can read my post on Passing the Godan.

Someya Sensei

Someya Sensei is a direct descendant of a Samurai family, and it shows. There’s an air of seriousness to his class that demands your focus and attention. Although, when the moment lends itself, you’re likely to share a good laugh about something that comes up in class.

Someya’s movement is precise – like the edge of a katana; it’s impeccable. If you’re curious about the “correct form” of a certain kata – watch how Someya Sensei shows it. He seems to teach the most from what is “written” in the scrolls. He is, as you would expect, the weapon’s specialist of the group; whether he is teaching a katana or naginata kata, he moves fluid yet maintaining incredible control. This is not just with weapons, but extends to his taijutsu and body movement.

He also is very detailed in what he teaches – especially when it comes to weapons. There are many subtle things in a kata that are important to make the technique actually effective, and there is also a historical reason for the methods of the kata. And if you don’t pay attention to some of these details, the technique will fall apart.

An Anecdote

One trip to Japan, a school from Ann Harbor Michigan came with us, and one of the teachers was telling a funny story about his heritage. He said “an Irishman will crawl through a mile of [excrement] because half way he’d look back and say to himself ‘might as well keep going – if I turn back now I still half the crawl the same distance and I’ll still get no potato’”. We then started walking towards Someya’s class at his school – a couple miles from the train station. On the radio it was talking about an incoming typhoon. Just so happens, we got to walk through the peak of it. Needless to say we were soaked by the time we arrived at Someya’s dojo – which was closed. We thought maybe we got the time wrong. So there we are laughing as the violent weather continues, hiding under the the roof on Somea’s dojo’s porch. Forty-five minutes go by, whensuddenly a beam of a flashlight comes from around the corner – it’s Somea Sensei. He takes one look at us and starts laughing. He goes over to Shihan Woodard and says quietly to him (in Japanese) “You know- there’s a typhoon passing over tokyo”. He had canceled the class, and was nice enough to call us a cab back to the station. While we waited, we talked and laughed, and got to get to know Somea Sensei a little better. That was our potato.

Sakasai Sensei

Sakasai is relatively new to teaching at the Honbu. From what I’m told he was a student of Noguchi. I was told his class was about Kihon – but I can tell you that it’s not the kind of kihon you think. Sakasai forms a bit of a bridge between the orthodox forms and the more fluid style movements you see of the other teachers and Soke himself.

The class is more focused than Noguchi Sensei’s class, but if you trained with either you’ll notice overlap. For example he will often use every student as an uke. However there is more repetition, a slower pace and more linear flow to absorb what is being taught. By the end of class, you’ll suddenly see a whole new side to the movement of our art, as well as be better equipped to follow along with other teacher’s training.

You’ll begin to see how to bridge the gap between the basics and the principles.

A Graciousness

Every time I’ve taken a class with Sakasai, he is super friendly and gracious: he actually thanked everyone for coming to his class. This showed a level of humility that is refreshing for someone of his skill level. Although his English is limited, he is always willing to engage in small talk (depending on how much Japanese you can speak). Just someone you know you’d like to hang out with in addition to learning from.


Sakasai Sensei was made Soke of both Takagi Yoshin Ryu Jutaijutsu and Gikan Ryu Koppojutsu.

Final Thoughts on the Martial Arts Instructors

Training in the classes in Japan was always a dream of mine. And each of the above teachers are truly amazing. There are other martial arts teachers at the Hombu Dojo as well. However, I haven’t trained enough in their classes to give any perspective – something I hope to correct by my next trip to Japan.

As I said at the beginning, I suggest training with all of them. Each one is highly skilled and will offer insight into the art and the movements of Soke. Hopefully this can give you an idea of the spectacular training that can be found at the Bujinkan Hombu in Japan. Until then – keep training!

Shikin Haramitsu Daikoumiyo

If you’ve ever taken a Martial Arts class at a Bujinkan Dojo, you’ve heard those three somewhat difficult Japanese words shouted at the beginning and end of class: Shiken Haramitsu Daikoumyo. These words have profound significance – but only if you understand what they mean (much less say them). Here we’re going to translate this Buddhist mantra, and the meaning behind one of the most often used phrases in Bujinkan training.

Shu-Ha-Ri: Phases of Training

Shuhari – “Preserve, Break, Transcend”
There are considered 3 phases of training in Bujinkan Ninjutsu (and most Japanese Martial Arts) – “Shu, Ha & Ri”. These phases focus on what the intention and the approach of the student should be towards their training at a particular level.

    I wish I had found this post before I headed over to Japan. It would have helped me know what to expect. There is very little on the internet on the personality of the various instructors, as if the person was not as important as the skills imparted. I disagree, the instructor will always colour the skills by his/her own personality, and I believe understanding the personality will be a great help in understanding the skills. 🙂

    Hi Scott

    !! What about detailed description of Senoh sensei, and Ishizuka sensei ??!! – Dai-Shihans, from the same first class students of Hatsumi sensei… and as important as those mentioned above!
    I reckon it would add much to your fine list above, and refine it… 🙂

      Hi Ze’ev, I didn’t mention them because at the time of writing it, I didn’t feel I had enough training with them to offer insight into their training. Has nothing to due with their ability or qualification, as you mentioned they are some of Hatsumi Sensei’s longest training students. Hopefully I’ll be able to train more with them and be able to offer some insight. I will probably do another article as a follow up to this one once I attend more of their classes. Thanks very much!

  3. Max

    Hi Scott,

    I’ve practiced Judo, Karate and various Kung Fu styles my entire life, but no Ninjutsu.
    Do you know of any possibility to train intensively (every day) at the Bujinkan Honbu dojo or the dojos of any of the teachers you mention, as a beginning student?


    • Shidoshi Hamilton

      Hi Max,

      Excellent question. I do know that some people have started their training at Hombu. Let me do a little digging for you and see how a resident would begin class there without having previous training.

  4. Clark Sabakuhasu

    This is very informative, I have bin studying the material of Ninjutsu by Soke Hatsumi-san , S.K. Hayes-san and Richard Van Dank-san and few others for many years. I have no ranking more of an independent, but what I have learned and practice has em barest those who have rank, saved my life and others. I am in process of moving my business to introduce Japan to my products line of energetically enhanced water and service. And it would be a great honor to be apart of this rich, beautiful and exciting cutler and to be considered a student of any or all of these great masters Be the Peace +;)

  5. Trevor Cuthill

    I trained for 2 years under Bill Atkins. He is ranked Jugodan menkyo kaiden.
    He shared a lot about his experiences at the Hombu. Every instructor has a unique flavor and style.

    • Scott Hamilton

      We had one of his students, Robbie Allen, teaching at our dojo before he moved. We talked a lot about Bill and some of the stories Bill shared with Robbie. Robbie is very skilled and a great reflection of how great a teacher Bill must be.

    • Duane

      Trevor Cuthill, I have trained with will for many year, when did you start training with him?

  6. Duane

    Trevor Cuthill, I trained with Bill for a total of four years. When did you train with him?

    Rest In Peace Seno Sensei.😔
