Shiatsu in a Massage Chair: Origins, Techniques, and What the Chair Can Do

Shiatsu literally means “finger pressure.” The term first appeared in 1928 in a Japanese medical publication, though the technique itself is older and traces its origins to Chinese medicine. It took on its modern form in the 1920s through Tokujiro Namikoshi, who combined Far Eastern acupressure with Western massage techniques . The Japan Shiatsu College, which he founded, has been teaching in Tokyo since 1940 and continues to operate today.

What Sets Shiatsu Apart from Other Massages

There is no rubbing or kneading. The technique involves applying vertical pressure, traditionally with the thumbs, as well as with the fingers and palms. Pressure is applied, held, and then released at points along the meridians, as described in Chinese medicine.

The second difference is practical: Shiatsu is traditionally performed with the client fully clothed, without oil, and often on a mat on the floor. It focuses on pressure, not on gliding over the skin.

How a session with a therapist works

A session usually lasts 50 to 60 minutes. It begins with a discussion about symptoms and the patient’s life situation, followed—in many approaches—by a hara diagnosis: The therapist palpates the abdomen, because, according to the teachings, the twelve main meridians originate there. Some practitioners also take the pulse.

The session then begins, with the patient fully clothed and usually lying on a mat on the floor. The therapist feels for patterns of tension and then works along the meridians: applying pressure, making circular motions, stretching, and then releasing. Pressure is applied with the thumbs and palms, and, depending on the body part, also with the elbows, knees, or feet, and the pressure is continuously adjusted based on the patient’s feedback. The session concludes with five to ten minutes of rest.

To achieve noticeable results, therapists usually recommend a series of five to ten sessions, followed by maintenance sessions every four to eight weeks. That's the point at which many people start thinking about buying a massage chair.

The Meridians

Shiatsu is based on the concept of energy pathways—the meridians—which originate in Chinese medicine. According to this concept, twelve main meridians connect organs, muscles, and bones, and Qi flows through them. Blockages in these pathways are considered the cause of ailments, and releasing pressure is seen as the way to resolve them.

You don’t have to agree with this model to benefit from the treatment. The points targeted by Shiatsu are, for the most part, located where Western anatomy also identifies muscle attachments and trigger points. Namikoshi himself explicitly incorporated Western anatomy into his teachings.

What the Research Says

A systematic review of studies on shiatsu and acupressure reaches a two-part conclusion. The strongest evidence of effectiveness is found in the treatment of pain, particularly in the lower back, as well as in improving sleep quality among older adults in long-term care facilities.

There is a caveat: The evidence base is particularly robust for acupressure, with meta-analyses and dozens of controlled studies. For Shiatsu in the strict sense, the evidence is sparse; the authors explicitly describe it as insufficient in both quantity and quality. Furthermore, the studies examined treatments performed by people, not by massage chairs. Anyone who tells you that a chair has been proven effective is ignoring this distinction.

How a Massage Chair Performs Shiatsu

An armchair doesn't have thumbs. What it replicates is the principle of focused, vertical pressure that is sustained, rather than stroking across the back.

Instead, the massage heads move to a specific spot, apply deep pressure, and remain there. For chairs with 3D technology, you can adjust how far they penetrate; the program controls the duration at each point. Models with body scanning don’t fix the pressure points rigidly, but instead align them with your shoulder height and the curve of your spine. Fujiiryoki developed the two-ball mechanism to achieve this precision: Two heads move into the groove between the shoulder blades, where four wouldn’t fit side by side.

What the chair cannot do: respond to what a therapist feels with their hands and learns during the session. It simply works through the points specified by the program. Chairs with pressure sensors come closer to this because they measure the muscle’s counterpressure and adjust the force accordingly. A Shiatsu therapist cannot be replaced by this.

Acupressure, Acupuncture, Shiatsu

These terms are often used interchangeably. Acupuncture uses needles, acupressure applies pressure to the same points, and Shiatsu is the Japanese version of the pressure-based technique, supplemented by stretching and Western anatomy. When a massage chair advertises “acupressure,” it generally means the same thing as “Shiatsu”: localized pressure rather than stroking movements.

What Shiatsu Programs Are Good For

For specific areas that can be pinpointed. If you can identify exactly where the tension is, Shiatsu is more effective than a program that works the entire back uniformly. For broad-area relaxation, kneading and tapping are the more appropriate techniques.

Let's be honest: Shiatsu in a chair is no substitute for treatment by a therapist or physical therapy. It complements them—but you can do it every day without an appointment.

Try it for yourself

You’ll know within the first few minutes whether the targeted pressure suits you. Some people find it pleasantly precise, while others find it too direct. In our showrooms, you can try out the Shiatsu programs from several brands one after another: sit down and give them a try.
