"Katakori" (肩こり) — stiffness and aching across the shoulders and neck — is a word you will hear constantly in Japan, and many languages have no single equivalent for it. It is not just a figure of speech: the national health survey records it every time as the second most common self-reported symptom in the country.
In the Ministry of Health, Labour and Welfare's "2022 Comprehensive Survey of Living Conditions" [国民生活基礎調査], the proportion of people reporting at least one symptom (the "symptom rate") was 276.5 per 1,000 population. For both men and women, No. 1 is low back pain and No. 2 is katakori.
| Men | Women | |
|---|---|---|
| No. 1 Low back pain | 120.0 per 1,000 | 113.8 per 1,000 |
| No. 2 Stiff shoulders (katakori) | (2nd) | (2nd) |
| Symptom rate, all symptoms | 246.7 | 304.2 |
A symptom this widespread is unlikely to have a single cause or a single solution — that is what the statistics point to.
[Verify] The figures are based on the MHLW summary report. If giving the actual per-1,000 figure for katakori, take it from Table 98 on e-Stat (Japan's government statistics portal).
Strong stimulation is not suitable in every case. Avoid force strong enough to hurt.
Time spent in the same posture, eye strain, feeling cold, stress and more: several factors are described as being involved. The MHLW guideline on work with information devices (screen work) says not to continue for more than one hour at a stretch, and that advice sits in this context.
Too much exercise can cause it as well. Do not pin it on a single cause.
The right response differs with the condition. Do not judge every case the same way.
If you have numbness, weakness, strong pain, or symptoms that persist, do not rely on your own judgement — see a doctor. Another cause may be hidden behind it.
