Rohto — Japanese Eye Drops & Skincare | Tsujimoto Market
About Rohto Pharmaceutical (ロート製薬)
Rohto Pharmaceutical was founded in Osaka in 1899 and has grown into one of Japan's most trusted healthcare and beauty companies. Best known globally for their medicated eye drops, Rohto has expanded into premium skincare, sun protection, and health supplements. Every Rohto product reflects over 120 years of pharmaceutical expertise — the same precision applied to medicine goes into their beauty formulas.
Rohto's Approach to Skincare Science
Rohto believes that skincare should perform at a pharmaceutical level. Their research labs in Osaka continually develop innovative active ingredients and delivery systems. Notable achievements include the development of Vitamin C derivatives that penetrate the skin more effectively than standard ascorbic acid, and advanced UV filters that combine broad-spectrum protection with daily skincare benefits.
Rohto is also the parent company of Hada Labo, the No.1 best-selling facial lotion brand in Japan — a testament to their skincare innovation capabilities.

Frequently Asked Questions
Are Rohto eye drops safe for daily use?
Rohto eye drops are pharmaceutical-grade products. Most varieties are safe for regular use, but it is recommended to follow the instructions on the packaging. Typically, 1–3 times per day. If you wear contact lenses, choose varieties specifically labelled for contact lens use.
What is the difference between Rohto eye drop strengths?
Rohto eye drops come in multiple strengths, typically rated by their cooling sensation (0–5 scale in Japan). Mild varieties (0–1) are suitable for sensitive eyes and first-time users. Strong varieties (4–5) provide an intense refreshing sensation preferred by many Japanese consumers for quick eye fatigue relief.
What makes Skin Aqua sunscreen different from European brands?
Skin Aqua uses a Japanese UV filter system (including the advanced Uvinul A Plus not available in US formulas) that provides superior PA++++ UVA protection. The texture is significantly lighter than most Western sunscreens — it absorbs instantly with no white cast or greasy feel, making it ideal for humid climates and daily wear.
Can I use Rohto skincare products if I have sensitive skin?
Rohto's skincare lines, including Hada Labo, are formulated without common irritants. Their sunscreens are also dermatologically tested. However, as with any product, a patch test is always recommended for very sensitive or allergy-prone skin.
Do Rohto products expire quickly?
Rohto products have a standard shelf life of 3 years unopened. All products at Tsujimoto Market are freshly stocked from Japan with long expiry dates. Eye drops, once opened, should typically be used within the timeframe stated on the packaging (usually 30 days for preservative-free varieties).
