\"2026<\/p>\n

A runny nose that won’t stop, a blocked nose that ruins your sleep, sneezing fits the moment you wake up \u2014 allergy troubles are not just a spring thing. Beyond pollen, dust mites, house dust, PM2.5 and the temperature swings between seasons<\/strong> are all common triggers of allergic rhinitis. Japan’s over-the-counter allergy medicines are a long-time drugstore favorite: second-generation antihistamines<\/strong> keep you clear-headed during the day, combination formulas with a decongestant<\/strong> tackle stubborn congestion and the kampo formula Shin’i-seihai-to<\/strong> works on sinus build-up from the inside. Different symptoms need different ingredients and antihistamine generations, and picking the wrong type can leave you drowsy and still blocked up<\/strong>.<\/p>\n

This guide sorts the field by symptom and by ingredient generation \u2014 from second-generation antihistamines and combination decongestant formulas to kampo \u2014 and picks 5 Japanese OTC allergy medicines worth ordering, with their key ingredients and Japanese reference prices. Order through FROM JAPAN<\/a> and you can get the full Japanese lineup that is hard to find elsewhere, without flying to Japan.<\/p>\n

Disclaimer<\/strong>: This article is general information, not medical advice. Use Japanese OTC medicines exactly as directed on the package. See a doctor if allergy symptoms persist or worsen, or if congestion comes with a high fever, severe facial pain or changes in your vision. Antihistamines can cause drowsiness, so do not drive or operate machinery after taking them.<\/div>\n
Shipping & import notes<\/strong>: All 5 picks here are oral tablets or capsules<\/strong>, which ship normally by Japan Post. Pressurised nasal sprays cannot be shipped and are not included.<\/strong> Medicines ship by Japan Post only, the US mainland is not on FROM JAPAN’s shipping list, and import rules differ by country \u2014 please check your own customs and health-authority rules before ordering, and keep items in their original packaging. Rohto Alguard Gold Z contains pseudoephedrine<\/strong> and Alesion 20 contains oral epinastine<\/strong>; both are restricted or prescription-only in some countries, so confirm before you order (see the notes on each item below).<\/div>\n
