Symptoms and Diagnosis
Atopic dermatitis has a characteristic presentation:
Diagnosis in Japan:
Japanese dermatologists use established diagnostic criteria (Hanifin and Rajka criteria, widely used globally). The consultation typically involves:
- Visual skin examination
- Allergy testing (patch test, RAST blood test) if triggers are unclear
- Scoring of severity (SCORAD or EASI scales) to guide treatment intensity
Treatment in Japan
Japan offers excellent dermatological care for atopic dermatitis, including some treatments that may not be as widely available in your home country:
Topical treatments (standard of care):
- Topical corticosteroids (ステロイド外用薬): mainstay of flare treatment; available in multiple strengths
- Tacrolimus ointment (タクロリムス / Protopic): widely used for face and sensitive areas; requires prescription
- Delgocitinib cream (コレクチム): Japan-developed JAK inhibitor cream; first approved in Japan in 2020 before many other countries
Systemic treatments (for moderate-severe cases):
- Dupilumab (デュピクセント / Dupixent): biologic injection; available in Japan since 2018; requires referral to specialist
- Oral cyclosporine: used in Japan for severe cases; requires specialist prescription and monitoring

Moisturizers widely available in Japan without prescription:

Cost Estimate
Dupilumab (Dupixent) injections require an ongoing specialist relationship and are generally not initiated for tourists during a short visit. If you use dupilumab at home and need advice on continuing treatment while in Japan, discuss with a dermatologist in Japan who can advise on your specific situation.

Frequently Asked Questions
Q: Will Japan's water quality affect my eczema?
A: Japan's tap water quality is excellent and is generally soft to very soft in most major cities. Many eczema sufferers from hard-water regions (like London or Paris) report less skin irritation in Japan. However, individual responses vary — rinse skin well and moisturize after showering regardless.
Q: Can I enter an onsen (hot spring) if I have eczema?
A: It depends on the severity of your condition and the type of onsen. If your eczema is in remission, low-mineral simple-water onsen are generally tolerable. Acidic or sulfur-rich onsen should be avoided. Always rinse with fresh water afterward and apply moisturizer immediately. Check with the facility — some prohibit entry with visible rashes.
Q: Is Protopic (tacrolimus) available in Japan?
A: Yes. Tacrolimus ointment (タクロリムス外用薬, brand name Protopic プロトピック) is available in Japan by prescription and is widely used for atopic dermatitis, especially on the face and sensitive areas.
Q: Can I get dupilumab (Dupixent) in Japan as a tourist?
A: Dupixent is available in Japan through dermatologists and allergists, but it requires a proper medical evaluation and is typically not initiated as a short-term tourist. If you already use Dupixent at home, bring sufficient supplies; if you have concerns about a missed dose, consult a specialist in Japan.
Q: Japanese skincare is famous — what products are good for eczema?
A: Japanese pharmacy shelves are excellent for eczema-prone skin. Look for: Hirudoid soft cream (heparinoid moisturizer — outstanding), Curel skincare range (ceramide-based), Vaseline petroleum jelly, and hada-labo (HA-based hydrating products). Fragrance-free options are widely available.
Q: Will cedar pollen season affect my eczema?
A: If your atopic dermatitis has an allergic component (which most does), cedar pollen season from February to April can significantly worsen your skin. Consider antihistamines, protective clothing, and air filtration if visiting during this period.
