Japan

Chiso, 6th century CE

Medicine crossed the sea, and the state took charge of it

Chinese medicine reached Japan in the sixth century, carried with Buddhism, and the physician Chiso is named as bringing acupuncture from Wu. Japan then went to the source, sending envoys and students to study in Sui and Tang China.

In 701 the borrowed art was written into law. The Ishitsu-rei, Japan's first medical statute, ran to twenty-six articles and defined the standing of acupuncture doctors, acupuncturists, and their students, alongside massage doctors, massage therapists, and massage students.

Anma, the pressing and rubbing massage whose two characters mean press and rub, entered Japanese history as an office of the imperial government. Manual treatment held a rank.

The Ishinpō, 984

Japan's oldest medical book is a compilation of Chinese sources

Tanba no Yasuyori presented the Ishinpō to the emperor in 984. Its thirty scrolls are the earliest extant medical book in Japan, and the Tokyo National Museum holds it as a National Treasure.

The book cites about two hundred Chinese and Korean medical works and draws its material from Sui and Tang learning. Its range covers acupuncture and moxibustion, herbal prescription, diet and hygiene, obstetrics, and the care of children. It is a curated library rather than a treatise.

Japan's founding medical text is Chinese knowledge selected by a Japanese physician, and the selecting is the Japanese act. The instinct runs through everything after it: receive the inherited thing, test it against the patient, keep what survives the test.

Ki, ketsu, sui

What Japanese medicine reads when it reads a patient

Ki is the vital current Japanese medicine inherited from Chinese qi, understood to move through the keiraku, the channels running over the body. Kampō diagnosis works from ki together with ketsu, the blood, and sui, the water, and treats the three as the circulating elements of the body.

Ki is read in two directions. Deficiency shows as fatigue, poor sleep, cold sensation, shortness of breath, loss of appetite, and low mood. Excess shows as high blood pressure, weight, and a flushed face. Stagnant ki shows as mood swings, irritability, and a distended abdomen.

The reading produces a pattern, called sho, defined in current practice as the complete clinical presentation of the patient at a given moment in time. The prescription is matched to the pattern rather than to a disease name, a principle Japanese practitioners call hōshō sōtai. A patient with one diagnosis and two patterns receives two different formulas.

Kampō

Japanese herbal medicine cut the theory and kept the examination

Kampō is the herbal tradition Japan built from Chinese prescription, and it diverged sharply from its parent. Japanese physicians judged the highly theoretical and speculative character of Chinese medicine inadequate for daily practice. They reduced the vast Chinese materia medica to roughly three hundred drugs combined into roughly three hundred prescriptions.

Yoshimasu Tōdō pressed the point hardest in the eighteenth century, insisting that the physician rely on what examination reveals. To gather that evidence he refined fukushin, palpation of the abdomen, which remains a defining feature of kampō diagnosis alongside the pulse and the tongue.

The tradition nearly ended in 1876, when the government required every physician to train in Western medicine. It came back through practice. In 1967 the first four kampō extracts entered the National Health Insurance list, and 148 formulation extracts are covered today, prescribed by 80 to 90 percent of Japanese physicians.

Anma

Pressing and rubbing, specified down to the manner of contact

Anma is kneading, pressing, and stroking along the keiraku, worked by thumb and palm with no instrument at all. It descends from the Chinese manual tradition and reached Japan with the rest of continental medicine, and the 701 statute already treats it as a profession with its own teachers and students.

Its diagnostic method lives inside the touch. The practitioner finds where tissue lies slack and where it stands defended, where warmth pools and where it is missing, and works from what the surface reports about the state beneath.

Japan still licenses the art. Practitioners of anma, massage, and shiatsu are regulated under Act No. 217 of 1947, whose official English title names finger pressure beside massage, acupuncture, and moxibustion. Anma is a living occupation with a national examination, not a historical curiosity.

Sugiyama Waichi, 1610 to 1694

The blind masters who made the hand the instrument

Sugiyama Waichi lost his sight in early childhood and became the most consequential figure in Japanese acupuncture. He devised the shinkan, a slender insertion tube through which a fine needle can be placed precisely and almost without pain, and the shogun Tokugawa Tsunayoshi granted him land at Honjo Hitotsume.

In 1682 his private school in Edo became a school of acupuncture for blind students, described as the first organized vocational education for blind people anywhere. It expanded to forty-five lecture halls. Sugiyama himself rose through the ranks of the guild of blind men to kengyō and then to sō-kengyō, its highest grade.

Over ninety percent of Japanese acupuncturists use the insertion tube today. Japan continues to train visually impaired practitioners in acupuncture, moxibustion, and anma, with one university and sixty-eight publicly funded schools for the blind or centers for the visually impaired reported in 2009.

For more than two centuries, the most skilled manual practice in Japan was carried out by people who could not see the patient. What they had was pressure, temperature, texture, and resistance under the hand, and it was enough to build a national profession on.

Sekkotsu and judo therapy

The bonesetters who kept the frame

Sekkotsu, bonesetting, is the separate Japanese lineage that works on structure, and it grew up beside the martial arts. Researchers trace judo therapy to first aid for jujutsu injuries, carried through the sekkotsu of the Tenjinshinyō-ryū school and refined with increasing medical specialization in the Taishō era.

The Judo Therapists Law of 1920 gave the craft a legal definition. A judo therapist treats fractures, dislocations, bruises, sprains, and muscle strains without surgery, and the license remains Japan's only national qualification in bonesetting.

Japan licensed its bonesetters into the national medical order instead of legislating them out of it. The choice preserved a body of manual knowledge about joints and their range that most industrial countries lost in the same decades.

Shiatsu, twentieth century

Shiatsu is a modern formalization, and its dates are recent

Shiatsu is not ancient. Tokujiro Namikoshi established it as a therapeutic system in the 1920s, integrating it with modern anatomy and physiology, and coined the word shiatsu, which means finger pressure. It has been taught in specialized schools since 1940, and the Ministry of Health recognized it in 1964 as a distinctly Japanese therapeutic treatment.

Shiatsu is defined by the manner of contact. Pressure is applied with thumbs, fingers, and palms, held perpendicular to the surface and carried by the practitioner's body weight, without any instrument. Shizuto Masunaga and Katsusuke Serizawa developed the other founding styles, and between the three of them almost every shiatsu practiced in the world today has its source.

Shiatsu inherited the pressing and rubbing of anma, the abdominal work of the kampō examination, and the channel map of the keiraku, then rebuilt the whole on anatomy that Sugiyama's generation did not have.

The inheritance

What a thousand years of Japanese practice put in the hand

Japan received a foreign medicine and turned it toward touch. Kampō curated the formulary, fukushin put diagnosis under the thumb, anma pressed and rubbed the channels, the bonesetter restored the joint, and shiatsu found the point through the skin.

The order of operations never changed: read first, then act. The abdomen, the channels, the tissue, and the manner of the patient are assessed as one condition. Only then is a formula or a pressure chosen, and the pattern the assessment produced is what decides which one.

That is a claim about the body, and it is testable. It says the body holds a single condition that shows up everywhere at once, that a trained hand can read it, and that it can be moved back toward its middle by graded input. Japanese practice bet a thousand years and a national licensing system on it.
