Looking forward, IMARC Group expects the market to reach USD 16,741.44 Million by ​2033​, exhibiting a growth rate (CAGR) of 5.29% during ​2025-2033​. At present, Japan is observing a constant increase in its geriatric population, which is positively influencing the market. Additionally, the growing penetration of e-commerce and digital health platforms is offering a favorable market outlook. Furthermore, the rising trend of self-medication among the masses as a way of treating minor illnesses is expanding Japan over-the-counter pharmaceutical market share.

Japan Over-the-Counter Pharmaceutical Market Trends:

Rising Interest in Self-Medication

The growing trend of self-medication among the masses as a way of treating minor illnesses is driving the demand for over-the-counter (OTC) pharmacy products. The trend is driven by the large number of health-literate individuals and the ready availability of information, which allows people to make well-informed decisions when it comes to non-prescription medication. Consumers are actively buying OTC products for conditions like colds, headaches, digestive discomfort, and allergies without going to a healthcare provider. Furthermore, the ease of buying medicines directly from pharmacies, supermarkets, and websites is facilitating this attitude. The efforts of the Japanese government in promoting self-medication to de-congest the national healthcare system are also contributing significantly. Legislators in 2025 sanctioned a measure permitting over-the-counter (OTC) medications to be sold in convenience stores and comparable venues in Japan, including those lacking on-site pharmacists. The amended law, approved by the House of Councilors after previous consent in the House of Representatives, is set to take effect in spring 2027. Consequently, the trend of self-medication is restoring patient health patterns and contributing to the Japan over-the-counter pharmaceutical market growth.

Growing Geriatric Population Driving Chronic Disease Management

Japan is observing a constant increase in its geriatric population, which is positively influencing the market. Being the world's oldest society, the country is facing increased demand for OTC drugs addressing age-related ailments like joint pain, insomnia, gastrointestinal problems, and mild cognitive impairment. The elderly are increasingly turning to OTC medication to treat chronic, non-life-threatening illnesses with convenience and affordability. The preference for OTC medications is also driven by an ambition among the elderly to live independently and curtail regular doctor visits. Pharmaceutical firms are reacting by creating age-suited forms, such as easily swallowable tablets, topical use, and more transparently labeled products. Additionally, chain pharmacies are proactively educating older buyers and providing counseling services to avoid adverse use. This age-related shift is maintaining a consistent demand for OTC medications while also facilitating innovations to enhance the health requirements of seniors, thereby increasing market growth. According to government data, Japan’s senior population has accomplished an all-time high of 36.25 million individuals, with those aged 65 and older making up nearly one-third of the country's population. In 2024, Japan’s Ministry of Internal Affairs and Communications announced that senior citizens constituted an estimated 29.3 percent of the population, which was a greater share than in any other nation or area with over 100,000 residents.

Changing E-Commerce and Digital Healthcare Channels

The Japanese OTC drug sector is driven by the growing penetration of e-commerce and digital health platforms. Moreover, people are buying OTC medications online because of convenience, wider product offerings, and anonymity of shopping. Online stores, specialist health websites, and health apps on mobile phones are giving access to a wide range of OTC products such as painkillers, dermal care, supplements, and traditional medicines. The combination of artificial intelligence (AI)-based suggestions and online consultations is also building customer confidence and purchasing confidence even in advance. Japan's tech-savvy individuals are welcoming loyalty schemes, subscription services, and easy-to-use interfaces of online pharmacies in a big way. Relaxation of regulations for online marketing of OTC medicine is also making this digital shift easier.
