Distance and Time, Ma-Ai


The study of distance and time is essential in the martial arts. In Japan, there is a word “ma-ai” which could be said to be the study, application, or the use of distance and time. With distance and time all problems can be solved!

The once gleaming palaces for kings and queens now lay in rubble where only foxes play and birds sing in the trees that grow in the ruins.  The Kings and queens, for all their court affairs, have vanished. Evaporated into the air with distance and time. If you can correctly understand distance and time, your life can become easy and joyous like the foxes and birds.Screenshot_2020-06-16 All sizes Happy foxes playing Flickr - Photo Sharing

My teacher often called his art the martial arts of distance and time.  Ma Ai. It is written with the characters, space/gap 間, and the character 会, meaning to come together or meet. It conveys the space between two objects, and the timing involved in an interaction or aligning of the two.

The distance between two objects or opponents, although often quantified with measurements, can also be vague and elusive.

One meter can be made to appear farther than it is and conversely can also be made to appear closer than reality.   Movement can also appear to be very fast when, in fact, you are moving very slowly and, at the same time,  can appear to be slow when you are moving quickly.

Just as the passage of time can feel different depending upon the situation, time flies when you’re having fun.Time can also drag when things aren’t so happy. As a child, one hour of math class seemed an eternity.  But the hour for play seemed over before it started.

Now as a father every day passes in the blink of an eye and I wish it would slow down like those lazy childhood days.  Some people report a sensation of the slowing of time when in dangerous situations or accidents, as if they were in slow motion. (myself included)

Distance starts with knowing where you are in space. Take the surface of a ball, like a basketball, and use it to represent the universe.  Forgetting for a moment the mathematical inadequacies of the example, wherever you place your finger on the ball, can be the center of the surface of the ball. Understanding that every point can and will be the center of the universe is an interesting to place to start! With an appreciation that all objects have a gravitational pull, the space between two objects becomes full indeed. Space no longer seems empty but becomes an almost tangible and malleable substance. This manipulation of timing and space or, in Japanese jiki and kukan, can be considered an aspect of Ma Ai.  With an understanding of these aspects, the feeling of Ma Ai will start to thrive in you.

My teacher loved to play with words and puns. He often interchanged the Chinese characters to create more subtle nuances for greater understanding and contemplation.  Many years ago, he changed Ma to devil and Ai to love which could be translated, among other ways, as love of the devil. But it has nothing to do with good or evil but an appreciation of the dedicated effort one must make to see the Ma Ai and the bravery needed to enter and manipulate it.

Perhaps if you love your demons enough, their horns will drop off and they can become angels!

Secret Transmission,Togakure Ryu Ninpo!

To thank you all for your generosity during this pandemic.  To show my great appreciation, I will try to translate bits of this book by Hatsumi Sensei that stand out to me.   This is one of my favorite books by Hatsumi Sensei and continues to shine bright even after 40 years or so.  Wisdom has a timeless beauty and this book is packed with gems.

This is the very first passage in the book and sets the theme and tone of the book.  Therefore I have decided to start at the beginning.  If this brightens your day or gives you some new inspiration in your training and study, it will most certainly brighten my heart as well!  Feel free to join our chats as well.  Now, lets jump in!

Poster 1

Philosophy of the Martial Way, Philosophy of the Way of Nin

This chapter forms the basis and main theme of this book. Therefore I would be delighted if you read it several times to capture the essence of it.

The Philosophy of Budo, the martial way.

In a grander view, the martial arts are used for the protection of ones` country. In a smaller view, they are used for the protection of the people and for the protection of oneself.

It could be said that striking with a sword using technique and artistry is martial arts. If you were to say that simply striking relying on brute strength in the arms and body is martial arts, then one could foolishly assert that chopping wood is a marital art!

The art of the sword is the study of the proper place, timing, truth of the, way to strike. Just as knowing the manner of wood or way in which a log can be split would be considered true wood chopping.

Using technique is an art. And the basis of art is in the heart. If the heart is not correct, there can be no progress. If the heart is not developed, there can be no understanding (of a proper way, greater truth). This understanding (of a proper way, greater truth) is similar to art. If actions are not proper (aligned with a greater truth and understanding), there can be no art.

True victory lies not with oneself but with the opponent. The opponent will naturally offer us the key to victory. Do not seek victory yourself but allow it come naturally to you. For it will come to you as surely as a spark is born when metal strikes flint.

It matters little if you are an Eighth degree black belt or a Master, it proves nothing. You must only taste deeply the essence of the most beautiful, subtle, and mysterious technique; If you think it exits, it does not. If you believe it is not, it is.

When the energy of the heart and the sword become one, this is the origin of the martial way.

The autumn moon

By Tomoe Gozen

Take a look out the window tonight(October 4th) and you will see the Chushu no Meigetsu. The Japanese have an ancient tradition of gazing at this moon on this particular date. They like to eat snacks, sing songs and quietly contemplate.

According to the lunar calendar, Chushu, 中秋 which means in the middle of autumn, was the 15th of August. They also call this moon Juugoya, 十五夜、 the night of the fifteenth. It used to always be a full moon but since the Japanese no longer use the lunar calendar, sometimes it is not completely full. But if you have not taken some time to look at the moon recently, dont miss this opportunity to slow down and enjoy some nature beauty and moon rays. You will be glad you did!

Nikko(日光) Trip :Things not to miss in Japan

BY Tomoe Gozen

I really liked visiting Nikko Toshogu(日光東照宮). It has so many decorations of animals like monkeys, elephant, cats, horses, Kirin, Dragons…and so on!

Sleeping Cat

Three wise Mokeys

Dragon on the ceiling

Now I see how these places have perhaps influenced the way Hatsumi Sensei decorates the Bujinkan Honbu dojo and even how my husband, Paul, decorates the Kasumian Study Center.

They both really like using animals in the Dojo and offices. I honestly thought that Paul was putting too many animal statues and things at our study center. But I found out that each animal has a symbolic meaning or important mythological role.

I truly enjoyed listening to the stories about each animal. I grew up in Shiga/Kyoto or Koga region, famous for Ninja. You can find many Ninja related spots in my hometown. The temples in this area and Kyoto seem more simple and less decorated than Nikko Toshogun.

“Wabi Sabi” is the word for a more simple and austere Japanese aesthetic. And it is this Wabi Sabi that I am more accustomed to in the Kyoto, or Koga area.

This was my first trip to Nikko and it was very interesting to see the differences between Kyoto’s temples and Nikko which is 17th century’s architecture.

Thank you to Stephan from Germany and Ricky from the USA for joining me on this lovely day trip. If you have not visited Nikko, I highly recommend it. It is an easy day trip from Noda city and it’s beautiful temples and inspiring forest paths with towering sacred trees will certainly refresh you and nourish your spirit! I will definitely visit again.

Otakaraya Antique store in Yokohama

Otakaraya Antique store in Yokohama posted by Tomoe

Paul and I like to look around antique stores to find  good  old Japanese stuff. It is a truely joy to decorate our Kasumi An Study Center with old Japanese antiques. We have a few favorite antique stores, but we think this place is the best.

They sell western cups and arts on 1st floor. But upstairs they sell really ancient swords, scrolls, and other antiques. Every time we go there, we talk with the guy at shop(I forgot his name).  He gives very useful information about the swords and other antiques. We like this shop not only because their selection is so good, but also because he is such a nice guy.  His knowledge is deep and wide .He has more than 300 katana in his personal collection and he told us he must clean a few swords every day one by one just for maintenance!  Chatting with him is so much fun. Unfortunately he does not speak much English, if you can understand a little bit of Japanese, you will enjoy this shop very much!


Here is the photos from this store.

Human Bonsai!

bonsai1Over the last twenty three years here in Japan, I often have the pleasure and honor to translate for my teacher Masaaki Hatsumi Soke. Often a student has a question that he would like to ask. It is a always a delight to be able to help facilitate communication between teacher and student. So many questions and so many unexpected answers! One episode comes to mind.

A student asks, “Why are some people friendly to your face but then are hurtful and mean behind your back?”.

Sensei replies nonchalantly, “that is just how people are made.”. As I translate, I can see the look of confusion cross the students` faces. I too am at a bit of a loss. So the question is asked again and once again the answer is the same,”that is just how people are made.”.  Then Sensei looks up into space and asks me, “Paul, have you ever seen a bonsai?”. (small miniature Japanese art trees)I nod my head “yes”. In fact, I had just taken some friends to a bonsai garden the day before so I was a bit surprised by the sudden question about bonsai. He continues, “it is like a bonsai, people are made. You can make a person any way. But it is not natural. You would not go to a forest and find a bonsai. It is not a natural state. But you can twist a bonsai into any shape you want. People are the same.”

How true! Just the prior day I was remarking on the branches of the bonsai. Each branch wrapped with wire and forced to go this way or that way. Every branch! bonsai3Each branch wrapped in wire and forced to take a seemingly natural posture or kamae. And how unnatural it really is. We, too, as humans, each being wrapped in the culture, politics, education, religions and beliefs of those around us and society. Some people wrapped as capitalists, some marxists, some Christians, some Muslim. But all are being bound by the conditioning of the environment and society. Then what you think are your own thoughts can betray you.  In a tragic conclusion, we often we take a kamae or stance for or against another wrapped up in a different shape. Both unaware of the wires that trap them in this position.

Unwrapping these wires and constraints is an important step in the practice of Ninjustu. A true ninja will become free and his tree will grow strong and pure into a natural state in accordance with the natural state of his existence. A Ninja is able to explore his true essence in infinite space. That is why in the Go Jou or Five Precepts as taught by my teacher, a constant diligence and watchfulness to your true path is essential. First become aware of where you are now. What shape are you now? When your shape become visible, start unwrapping!

Kan Nin Dokuso (part one)


Artist: Paul Masse 2007. Inscription: 天上天下唯我独

“In the all the heavens and earth, only I am exalted!”

Kan Nin Dock Son is a phrase you may hear around the Bujinkan dojo this year. Is it the theme for the year? Maybe, maybe not. Who knows?! But whether it is a theme or not is really not important, it should give you something to ponder and explore this year in addition to your continued practice of the physical movement and techniques. Kan Nin 貫忍, steadfast and single-minded perseverance all the way. Doku Son 独尊、to be revered or exalted. It most likely refers to a story of the Buddha. The story is, when he was born, the Buddha took seven steps and pointed one finger up and one finger down and exclaimed, “In the all the heavens and earth, only I am exalted!”.  What is this elusive I? Some think of it as me, my name, age ect. But you would lose some of the poetry. Who are you when your name, age, social status are stripped away. Going deeper, who are you when the body is stripped away and the mind faded and gone, and even your conscience vanishes like smoke after a fire?Maybe you have heard the Gokui (inner teachings) Persevere the body, Persevere the heart, and Persevere the conscience.

Your body had plopped out of this earth and it will dissolve back into the earth. No matter how good they wrap you like a mummy! But what of a natural energy? A power of nature that drives the seasons, sings thru a myriad of creatures? This power that keeps the clouds drifting and the water flowing, and an infinite number of stars alight? This natural power, the natural power of life is what we must become aware. When you have persevered thru all, this power will shine. Hatsumi Sensei once said to me, “it is like in the movies, when someone opens a treasure box, and their face is lit up by the golden light of the treasure.”. I really like this image. This is the treasure of Nin or Ninpo, 忍宝。 Kan Nin will help to uncover it. Be like Indiana Jones and go treasure hunting. The treasure is so near! When you uncover it, you won’t need to be and air bender or water bender or fire bender. You will know that you have been bending them all the time!

人心看破術 Jin Shin Kan Pa Jutsu


Visitor at the Kasumian.  Even though the dragonfly has two big eyes, They won`t help him with Jin Shin Kan Pa Jutsu.  Which eyes do you see with?

The other day I was in the dojo training when a friend who has not been in Japan came in and greeted me. His boyish good looks still evident but under a layer of new chubbiness. (Hopefully due to a good life overseas) My initial thought was “Wow, he`s gained some weight!”. Of course, as learned etiquette demands, I did not mention it and we began training. About five minutes later Hatsumi Sensei comes walking over and greets him with a hearty “Hello! Good to see you” and “Oh I see you have gotten fat!”. Well I almost fell over and the three of us burst out laughing. As I was catching my breath I hear my friend say to Sensei, “Yes it`s true, I have gained weight and my hair is changing to gray. I wasn`t sure that you would recognize me.”. Sensei replied, “of course I know you!”. What he said next was very interesting. He pulled us together and speaks, ” I may forget a face, and I may forget a name but I never forget the mood or feeling of person. This is important, to understand someone`s mood or the feel of that person.”.

Instantly, I am thrown back in time to last October (2015), Halloween, I had dressed as Harry Potter and came to the dojo early to joke around with my friends. After having a nice laugh with everyone in the dojo and before Sensei arrived, I changed into my dogi but kept the wig and wire rim glasses on; thinking I might fool Sensei. Some Japanese say all foreigners look alike anyways! A few minutes pass and Sensei enters the dojo and barely glances at me as he walks by. Immediately I know he knows. For he would have certainly greeted a new comer more warmly. I ask “Sensei, how did you you know it was me?”. He looks back over his shoulder at me and says “Of course, I know it`s you. I don’t look at the outside, I look at the inside of everyone.”.

A few days later, I am thinking about these two events when again I am thrown back in time to about ten years ago when Sensei used to tell us the importance of the art of Jin Shin Kan Pa Jutsu. The art of reading, seeing, sensing the heart, intent, feel of a person. To know a person instantly, know his intent, his heart, clear or dark. The importance of not being fooled by outwardly appearances. If you are always taken with the outwardly shapes, forms, colors of the people and things around you will often miss their truth, their intent, their nature – good or bad. This can lead a multitude of troubles, from being swindled in love and money, to more perilous, dangerous or even life threatening situations. The ninja often used the opposite of this, henso jutsu (disquise) to hide in plain sight. Often in our training, we enjoy the practice of the more outwardly and sometimes fun henso jutsu practice but forget about the this equally important inner ability. With consistent practice to nurture a calm clear heart, the art will naturally and surely take root. The ninja must endeavor to master both the inner and outer arts to ensure a safe and a happy return.

中今(Naka Ima) Here and now are the only realities.

This is a work of art for my friend Matthew by Hatsumi Soke. It reads in large characters, Divine Dragon (神龍) and in ancient “Age of the Gods” characters (kamiyomoji), Shiken haramitsu Dai Koumyo. Sensei often writes this for people who are having difficulties with health or as a general Omamori or talisman for protection.






When my good friend Willy Iglesia went to Japan at the tender age of 18 to train with Ninja Master Hatsumi Masaaki, his first lesson was an unexpected one.  Hatsumi Sensei took him to a restaurant and ordered two plates heaping with vegetables for the two of them.  Willy, being a young man from Argentina, (people form Argentina eat a lot of meat! How much? Well, think of a whole hell of a lot of meat and then think even more!) So Willy, looking at the plate of greens, says “Sensei, I don`t eat vegetables.”. The reply from Ninja Master Hatsumi, “First lesson, now eat vegetables!”.

We often forget the foundation upon which our Ninpo is based.  A healthy body/mind organism.  In his very first books on Ninpo, Hatsumi Sensei stresses the importance of proper nutrition and exercise.  Yet often we are controlled by our senses, eating and partaking in activities solely to please the greedy senses. My yogi teachers would say, “you are eating donuts to please the tongue while the liver dies in silence.”. These words I can never forget.  If you look deeply at this one sentence, you may grab the essence  of the Rokon Shojou 六根清浄  (禄魂笑浮)teachings of several years ago as well.

I  train a small Bujinkan group in Yokohama and have had the good fortune to meet Matthew Dons who became an ardent supporter, student and good friend. Matthew was recently diagnosed with stage four cancer having spread to many systems in his body. He is 36 years old with two small children. The prognosis is that he most likely has only a few months to live.  We live our life as if we have an unlimited amount of time.  Once I was speaking with Hatsumi Sensei about the later years of life. He said, “Don`t think about the later years, right now, these are the later years of your life.  live now. this is naka ima! (中今).”. Be in the middle of right now. The Buddha once said, “life is but a single breath.” How deeply can we live and love in this moment.  Often we think, when I get there, I will be happy then.  Remember, there and then are fictions. Here and now are the only realities.

If you are able and would like to help, please click the link below  to help Matthew fund his treatment and other expenses in this difficult time. We are hoping to extend his life for a few more precious moments to be with his family.  Wishing you all health and happiness, Now!

A side note. We once announced an opening party for Kasumian Study Center a year and a half ago, Matthew is the only one who showed. He came all the way from Yokohama to support us.  I am very grateful for the time we spent together. Thank you for being there Matthew.  Buyu 武友、武祐、武勇。All are pronounced Buyu. Martial friend, martial divine help, martial courage.  They are all of them you and may they continue to be with you!
