About Us


The International Japanese Yoga Association (IJYA) is a not for profit association devoted to the study of Shin-shin-toitsu-do, a form of Japanese yoga and meditation created by Nakamura Tempu Sensei.








The purpose of the IJYA is to make Shin-shin-toitsu-do style Japanese yoga available to people worldwide regardless of age, gender, or nationality. It has members in Japan, the USA, the United Kingdom, Australia, Estonia, Slovakia, Bulgaria, Canada, Malaysia, Slovenia, the Netherlands, France, India, Germany, Italy, Spain, South Africa, Sweden, Greece, Poland, and other areas. All members are treated equally and varying styles of Shin-shin-toitsu-do are accepted. 



Human beings have a tremendous latent potential that's waiting to be unearthed. Nakamura Sensei discovered the extraordinary energy of mind and body unification beside an ancient waterfall in the Himalayan mountains, allowing him to heal from tuberculosis and manifest a new state of consciousness. Upon his return to Japan, he created a new path called Shin-shin-toitsu-do: "The Way of Mind and Body Unification." A form of Japanese yoga and meditation, Shin-shin-toitsu-do unearths our buried talents and rarely realized potential.

The International Japanese Yoga Association (IJYA) is a not for profit association devoted to Shin-shin-toitsu-do. In Japan, the IJYA is known as the Kokusai Nihon Yoga Renmei, and its world headquarters is in Kyoto. Sawai Atsuhiro Sensei is the IJYA President. He is a best selling author in Japan, focusing on books about Shin-shin-toitsu-do and meditation. He is also a direct student of Nakamura Sensei, having obtained the highest level of teaching certification from the founder of Shin-shin-toitsu-do.

Sawai Sensei has appointed H. E. Davey Sensei as the IJYA Vice President and International Chief Instructor. Davey Sensei, an award-winning writer and the author of Japanese Yoga: The Way of Dynamic Meditation, oversees the day to day running of the IJYA. He studied under four top students of Nakamura Sensei and began practicing Shin-shin-toitsu-do as a child. He serves as the point of contact for IJYA members worldwide and works directly with the IJYA HQ in Kyoto. He has received the highest level of IJYA teaching certification. 

Membership in the IJYA is FREE. Members only need to provide their contact information and e-mail address to join. They receive an attractive membership certificate and a subscription to the IJYA Journal, the publication of the Kokusai Nihon Yoga Renmei. Qualified members are also eligible for teaching certification from the IJYA HQ in Japan. Send membership inquires to

Shin-shin-toitsu-do, which is also known as Shin-shin-toitsu-ho, has been widely practiced in Japan since the 1920s. Its founder, Nakamura Sensei, taught a very large number of students, many of them celebrities and well-known figures in Japanese society. However, outside of Japan this Japanese version of yoga is in its infancy, with few training centers in the West. Interested parties can learn about this art by reading Japanese Yoga: The Way of Dynamic Meditation (Michi Publishing), the first book in English about the original mind and body unification principles of Nakamura Sensei. Recently, Michi Publishing issued The Teachings of Tempu: Practical Meditation for Daily Life by Davey Sensei and The True Paths to Meditation by Sawai Sensei.


Direct instruction outside Japan is offered by Davey Sensei's Sennin Foundation Center for Japanese Cultural Arts in California, which serves as the hub of IJYA activities in the West. Visit for more information.

The worldwide IJYA Journal is a members only publication of the Kokusai Nihon Yoga Renmei (IJYA). IJYA membership is FREE. The journal is published periodically and offers instruction in Japanese yoga, meditation, and healing arts to the public. The goal is to make the teachings of Nakamura Sensei available to a larger audience than in the past, with an emphasis on making Japanese yoga available to more people in Western nations. The IJYA Journal is your chance to learn important mind and body unification principles that can help you in most every aspect of life. Plus, it's FREE to members, and our not for profit association will never give your contact information/e-mail address to other parties.
