50+ Years of Vitamin Innovation
Oronamin C isn't just a drink — it's a product of one of Japan's most trusted pharmaceutical companies. From its founding to today, Otsuka has poured decades of scientific rigor into every bottle.
Otsuka Pharmaceutical is established in Tokushima, Japan. From its earliest days, the company commits to a philosophy of "New Creations in Healthcare" — combining rigorous pharmaceutical science with everyday wellness products that improve people's lives.
Oronamin C hits the market as Japan's first vitamin C-fortified carbonated soft drink. The distinctive brown bottle — designed to protect vitamin C from light degradation — becomes an instant icon. The honey-citrus formula wins over consumers looking for a delicious way to get their daily vitamins.
Oronamin C becomes one of Japan's longest-selling soft drinks, a supermarket staple found in households across the country. Named the top cooling drink in Japan for 6 consecutive years, it earns a place in Japanese pop culture as the drink with the satisfying "BOOM" when you pop the resin ring tab.
Now available worldwide, Oronamin C continues to delight a new generation of health-conscious consumers. The same formula, the same brown bottle, the same vitamin-packed refreshment — over 50 years later, it remains as relevant as ever. Otsuka Pharmaceutical has grown into one of Japan's largest pharmaceutical companies, but Oronamin C stays true to its original mission: making wellness delicious.
