A rash spreads over the weekend, you search for a skin clinic, and the results are full of laser treatments and skin brightening. That is not a quirk of the search — it reflects who actually opens on a Sunday.
Counting by department, 1,019 facilities nationwide run dermatology on Sundays. Cosmetic dermatology runs at 1,231 — more, on Sundays, than the general kind.
The gap widens on public holidays
On public holidays it is 686 for dermatology against 1,118 for cosmetic dermatology, plus 820 for cosmetic surgery. Private treatment is sold to people who do not want to take time off work, so weekends are the core business.
Early mornings reverse it
Before 08:00 the picture flips: 136 facilities run dermatology against just 13 for cosmetic dermatology. Early slots serve people stopping in before work; weekend slots serve people spending their day off there.
皮膚科 (hifuka) is dermatology, covered by national health insurance. 美容皮膚科 (biyo-hifuka) is cosmetic dermatology and is private-pay. One clinic may list both, with different hours for each.

Getting insured treatment
- Filter for 皮膚科 rather than 美容皮膚科 on the search pages here.
- Where a clinic lists both, check its own site: the weekend session may be cosmetic only, even though dermatology appears in the listing.
- A rash with fever, one spreading fast, or a painful band on one side of the body (possible shingles) should go to general dermatology or internal medicine, not a cosmetic clinic.
