The People and Traditions Behind the Practices We Share
Every technique covered on Simple Senior Fitness comes from somewhere: from a Japanese clinician, a researcher, a temple posture, or a centuries-old collective practice. This page exists to give that attribution honestly.
Where a practice has a single, verifiable creator, we credit them by name and link to a primary source. Where it grew from collective tradition without one founder, we say so plainly. We're an independent site sharing what helped one of us, and we are not affiliated with any of the people, organisations, or traditions listed here.

Featured Pioneer
Dr. Toshiki Fukutsuji
Japanese chiropractor & shiatsu specialist
Dr. Toshiki Fukutsuji is a Japanese chiropractor and reflexology/shiatsu massage specialist who developed the rolled-towel posture-correction method over more than a decade of clinical practice. He observed that modern lifestyles (long hours of sitting, hunched shoulders over phones and laptops) had created an epidemic of back pain and forward-tilted pelvises. His insight was that gravity and a strategically placed towel could do the work that aggressive stretching couldn't: passively decompress the spine and gently coax the pelvis back toward neutral. His book on the technique has sold over six million copies in Japan and across Asia, and an English edition is available worldwide. The method has become one of the most accessible and widely practiced back-care techniques in Japanese wellness.
Prof. Dr. Qing Li is a Clinical Professor in the Department of Rehabilitation Medicine at Nippon Medical School Hospital in Tokyo. He is President of the Japanese Society of Forest Medicine and Vice President of the International Society of Nature and Forest Medicine. In 2004, the Japanese government asked him to research the health effects of time spent in forests, and the field of forest medicine grew from that work. His research established that phytoncides (the natural compounds emitted by trees) contribute substantially to the measurable health benefits of forest bathing, including changes in immune function, blood pressure, and stress hormones. His book Shinrin-Yoku: The Art and Science of Forest Bathing (Penguin Random House, 2018) brought the practice to a global audience and remains the most widely read introduction to the field.
Wataru Nagai was born at Sho-man-ji temple in Fukui prefecture, the son of a Buddhist monk. Rather than follow the family tradition, he chose business and rose to become a successful executive at what is now the Taisei Corporation. At the age of 42 he suffered a cerebral hemorrhage that left half his body paralyzed. Doctors said he would likely remain dependent on others for the rest of his life. Refusing to accept that prognosis, Nagai drew on the Buddhist temple postures of his childhood and developed four simple stretches that gradually restored his mobility over the course of the 1930s. He shared the technique only quietly during his lifetime. His son, Haruka Nagai, published the first Makko-Ho book in 1972. The practice has since spread well beyond Japan as one of the most accessible meridian-based stretching systems.
Dr. Keizo Hashimoto was a Japanese medical doctor from Sendai who studied Western medicine in Niigata. During his early years of practice he engaged deeply with traditional Japanese bodywork and Eastern medicine, eventually integrating both worlds in his own approach to treatment. He invented Sotai-ho (操体法), a gentle movement system whose name is intentionally the reverse of Tai-so (体操), the Japanese word for exercise. Where conventional taiso traditions emphasize forceful, regimented movement, Hashimoto designed Sotai as its quiet opposite: a practice built on the principle that the body heals by moving toward comfort, not by pushing through pain. His work became widely recognized throughout Japan in the 1980s and has since influenced physical therapists, somatic practitioners, and self-care teachers around the world.
Tomohide Akiyama served as Director-General of the Japan Forestry Agency in the early 1980s. In 1982, as part of a national public-health campaign, he coined the term shinrin-yoku (literally 'forest bathing') to encourage Japanese citizens to spend mindful time in the country's many forests for the sake of their wellbeing. The phrase was chosen deliberately to evoke the act of immersing oneself in the forest atmosphere with all the senses, rather than simply hiking or exercising outdoors. Akiyama's framing turned out to be remarkably durable: it gave both the Japanese public and later international researchers a clear, evocative name for a practice that has since been studied, documented, and adopted around the world. Today shinrin-yoku is taught and prescribed across Japan and abroad, but the term itself traces back to his 1982 campaign.

Tradition
Radio Taiso
ラジオ体操
Japan, 1928
Radio Taiso is a national calisthenics routine broadcast daily by NHK since 1928. It has been practiced every morning in schools, workplaces, and parks across Japan for nearly a century. The current most-broadcast version (No. 1) consists of 13 sequential movements lasting about three minutes. Although the routine evolved through several institutional iterations, it has no single creator. It belongs to Japan's collective public-health tradition.
Seiza is the traditional Japanese kneeling posture, tied to Zen Buddhism, tea ceremony, martial arts, and everyday etiquette. The word literally means 'proper sitting'. The position evolved over centuries of Japanese cultural life and has no single inventor. Rather, it became the default formal posture across Japanese society. Today it is still used in many traditional settings and is increasingly studied for its effects on hip mobility and posture.
The Hara is the body's vital center in Japanese tradition, a region in the lower belly, just below the navel, sometimes called the tanden in classical texts. The concept is rooted in Zen Buddhism and Japanese martial-arts traditions, where the Hara represents the seat of stability, breath, and presence. Breathing into the Hara (slow, deep, abdominal breathing) has shaped Japanese ideas of calm and centeredness for centuries and forms the basis of many breathwork practices.
Kinhin is a Zen Buddhist walking meditation, practiced between sessions of seated zazen to bring meditative awareness into movement. The founder of Sōtō Zen, Dōgen Zenji (1200–1253), described the practice in his work Eihei Shingi, and it has been transmitted within Zen monasteries for the eight centuries since. Outside Zen monasteries it is now used by laypeople worldwide as a gentle, mindful walking practice that pairs naturally with seated meditation.
Asa no Taisō is a Japanese tradition of light morning calisthenics: gentle movements practiced shortly after waking to ease stiffness and start the day. The tradition overlaps significantly with Radio Taiso and other broadcast morning routines, and is practiced informally in homes, schools, and workplaces across Japan. Like many of Japan's morning movement traditions, it has no single creator and evolved as a collective cultural habit.
Do-In is an ancient Japanese self-massage tradition that combines gentle stretching, breathing, and acupressure. Its roots reach back to the Chinese practice of Dao Yin (Tao Yin), from which the Japanese name and many of the techniques derive. Practitioners use their own hands to apply pressure along the body's meridian lines, supporting the daily flow of energy and circulation as part of traditional Eastern self-care.
