Getting Started

Visit a training session:

Please feel welcome to visit a training session, as listed on the schedule above. There is no need to pre-register, all training sessions are open to interested observers.

Experimental Classes:

If you are interested in participating, but not sure about enrolling, you can take part in experimental lessons for your first two visits. We will provide the necessary equipment, and you won’t have to worry about enrollment and equipment fees unless you decide to continue. The ideal outfit for beginners is a dark T-shirt and breathable workout pants.


Adults of all ages, men and women can train. There are no specific prerequisites nor the need to previously have physical training or experience in martial arts. The training brings technical, physical and interior progress to all ages and stages of life.


Children from 12 years old can participate in all training sessions.


Sessions last an average of 2 hours. Training sessions are made up of various parts, warm-up, basics of strokes and techniques, sequence training and combat. Combat training is usually divided up into groups of beginners, intermediates, and graduates, while at other times the more experienced may work with and guide the most novice. How frequently one should train depends on the potential of each student. With training just once a week, it will be easy to to see technical progress, physical and health-related benefits, and the assimilation of the principles and values of the Bushido philosophy. A lower frequency of training is still valid, and can provide results for students with less availability.


During any visit to the Dojo, try to stay until the end of the session and participate in the Golden Moments, when the training is complemented with elements of Japanese culture and Bushido samurai philosophy.

KIR Method:

KIR is a training method aimed at the physical, mental and emotional development of the student, giving little emphasis to competitiveness and discouraging the use of force. With this positive energy, the student feels confident to fully develop their potential.

What we train


The art of the samurai sword is still alive and can be practiced today, with the closest approximation of the experiences by which samurai lived for centuries. There are hundreds of stances and fighting techniques that are practiced during training sessions with the use of appropriate equipment for protection and safety.

Within Kenjutsu is practiced the Niten Ichi Ryu style, created by the samurai Miyamoto Musashi Sensei. The name of this style means “Two Skies as One,” alluding to the famous techniques of two swords, able to defeat the most skilled opponents with whom Musashi-Sensei crossed swords.
Welcome to the
Colorado Dojo
of the Niten Institute

Kenjutsu Combat, created by Sensei Jorge Kishikawa, is when you apply ancient Kenjutsu techniques in combat with modern armor (Bogu) and using bamboo swords (Shinai).

Niten Institute classes are not only for strengthening the body, but also the mind and spirit, by practicing the techniques and following in the footsteps of our founder, Miyamoto Musashi. This style of Kenjutsu Combat only recently arrived in the US with the 2017 visit of Sensei Kishikawa.

As such, we are very excited to announce the beginning of regular classes here in the Denver-Boulder region. We have secured a great location at the new Sport Stable in Superior, conveniently located less than a mile from the US-36.

Regular classes are currently offered twice a week, but make sure to check our schedule frequently for special guests and events.

Come discover the way of the sword!

No Japão com o Sensei 2

por Wenzel - 24-jan-2020


Pontualmente adiantado Sensei bate uma única vez na porta do quarto. É sinal de que estamos de partida. O momento é de pegar a mochila já arrumada, pular nos sapatos preparados em frente à porta, devidamente apontados para fora, e alcançar o Sensei no corredor rumo ao elevador.

Com o horário “confuso” ainda, eu havia dormido um pouco no início da noite e depois passei a madrugada em claro, respondendo emails e escrevendo o primeiro texto da viagem. Às 5h20 o Sensei ligou para o quarto, anunciando que o dia reservava quatro missões a serem resolvidas, rapidamente enumerou cada uma e confirmou que sairíamos às 6h00.

Foi o tempo de fechar o texto, incluir algumas imagens e vestir kimono e hakama.

Precisamente às 5h52 sete minutos adiantado o Sensei bate na porta. Se batesse às 5h53, seriam seis minutos mais alguns segundos. Para não se atrasar nem estes segundos, os 7 minutos adiantados do Sensei, são tão precisos que tem alguns segundos de sobra. É o que chamamos no Niten de Horário de Sensei. Temos no Niten sempre horário de Brasília (GMT -3), geralmente marcado nos celulares e temos o “horário do Sensei”, precisos 7 minutos adiantados, que é o horário vigente no relógio de pulso do Sensei. E é esse que vale quando estamos com o Sensei. Especialmente em Gashukus e Shugyos. Sim, às vezes é meio confuso, eu também já achei bem confuso. Porque não manter um horário só e marcar um pouco mais cedo?! Mas justo por essa confusão, acabamos jogando mais energia na percepção do tempo, temos que fazer sempre uma pequena aritmética e ficamos mais conscientes do tempo em que estamos de fato. Funciona.

Keeping the Tradition Alive

por Delfino - 09-set-2019

Last Sunday we held our first kenjutsu combat class! It was the perfect weather, not scorching hot nor freezing cold. Keeping the flame of Tradition that has been passed down to us by our Sensei alive!

Day of the Samurai, a day for reflection, learning and celebration!

For us, the secret to be happy is: Discipline and Party. Indissociable and interdependent things. It is not possible to live and be happy, practicing a rigid discipline without celebrating the advances and conquests. So little is viable to live only at a party without conquering anything. This applies to all aspects of daily life, whether in the Dojo, in professional life or in private life with family and friends.

The millenarian Japanese culture, studied and practiced by the old and new samurai practicing martial arts of the most diverse styles, gives clues to the way forward. Promote the strengthening of the body through the practice of a vigorous physical activity, which prevents ills, increases the quality of life and gives healthy longevity. And, at the same time, promote the strengthening of the spirit through learning and the practice of virtues that improve character and behavior as citizens.

Today we celebrate Samurai Day, always on April 24, the Day of Samurai.

Training in Bogota

por Pedro Casablanca - 19-mar-2019

Konnichiwa Mina-San
Shitsurei Shimasu,

With great joy, I would like to begin this testimonial by thanking everybody at the Colombia unit. I was fortunate enough to be able to travel to Bogota for business and vacation. Senpai Takeshi highly suggested to stop by at the Bogota Institute. At the Asociacion Cultural Japonesa, Senpai Andrés welcome me with open arms and treated me like I was one of his students. Looking forward for the training session to start. I was super excited seen Niten´s companions arriving at the dojo. We started the Saturday session with a strong Kiai, stretching, running through out the big dojo.
