The main characteristic of KENBU TENSHIN RYU is that although it takes the form of Kenjutsu that has been practiced in Japan since ancient times, it is a unique new style of “Iai-Batto Kenjutsu” that integrates tradition with the wisdom and cutting-edge approach of modern people.

KENBU TENSHIN RYU draws from various traditional schools of Bujutsu developed through the long history of Budo practice in Japan, and has revised and refined them to suit the needs of the modern era. It is based in Shintaido theory and practice that has gained worldwide recognition as a magical arts form. Emphasis on soft and graceful use of body, and Body Arts expressions embodied in the flowing sword techniques are finely integrated in its program of practice.

Kenbu Tenshin Ryu is intended to develop a healthy body, mind and spirit, as well as to awaken the senses through free body expression in order to gain the flexibility necessary for us to adapt to the changes of life. At the same time, learning the Way of the Sword provides opportunities for us to learn about the view of life and death of Japanese people that has been passed down through generations.

KENBU TENSHIN RYU practice focuses on creating flow of ki (energy), pursue the Truth of the Universe, live in harmony with Nature and its Law, as well as to

produce effective techniques while maintaining soft and fluid movement.

The great life force of the Universe is the very source of energy that created this great Nature, and it has been referred to in many different ways such as Tenshin, Ku, Mu, Amida Nyorai / Dainichi Nyorai, Dharma, Sophia, Hagion Pneuma (Fire, Wind, Breath, Holy Spirit), Amenominakanushinokami, God of the Universe, and etc. However, originally, they all mean the same in essence.

KENBU TENSHIN RYU honors and accepts this essential life force and seeks to open the consciousness to attain true mental and spiritual freedom. The practice also becomes an expression of prayer for world peace and purification, and practitioners are encouraged to pursue how to live in alignment with the Michi/Do (Way) that it guides us.

At TENSHIN SHOHO JUKU, students learn the basics of calligraphy by copying classical works of great Chinese Calligraphy Masters, as they also deepen their knowledge and understanding of brushes, papers, and ink stones.
Through the process of engaging in calligraphy and drawing lines mindfully, TENSHIN SHOHO JUKU provides a variety of opportunities for students to develop their potentials and pursue the style of their choice, ranging from standard or traditional calligraphy style, artistic style with much freedom and individuality, Bokuseki-like style (literal meaning of Bokuseki: “ink trace”. Refers to a calligraphy style of Zenga developed by Zen monks) with much depth, and healthy, intellectual style suitable for calligraphy education.

TENSHIN SHOHO JUKU encourages students to connect and live in harmony with the great Truth and life force of the Universe and Nature through calligraphy, in order to create an even better life.

“To teach is to talk about hope, To learn is to leave an honest impression” is a famous word by French poet, novelist, and critic, Louis Aragon (1897-1982).

A Bokuseki style work full of life, an artistic work equivalent to world-renowned masterpieces, a profound work that soars far above important intangible cultural heritage—all of these different directions can be pursued through Calligraphy at TENSHIN SHOHO JUKU.



Meditation has the power to deepen our minds, purify our souls, restore health, and develop our potentials. How wonderful would it be to learn the theory and practice of meditation in depth, and be able to use it for self-transformation?

As meditation helps cultivate concentration, we can also benefit from its ability to enhance memory and learn foreign languages. It can also help us become more open and social, and improve human relations.

If you have been carrying unidentified feelings of suffering, sadness, loneliness, self-hatred, solitude, complaints against others or resentment, meditation can help resolve these issues. Furthermore, for body practitioners (i.e. sports or martial arts), the relaxed state of body and mind attained thorough meditation will help produce powerful and effective techniques, promote body and mind unification, unify with others in a short period of time.

AOKI METHOD encourage students to engage in meditation that is like a gold mine for us wholeheartedly with a bright and fresh attitude, so that we can keep developing our potentials to realize our dreams.
