Otsuka Oronamin C Drink: Classic Japanese Energy Drink

Today in Japan, there are a wide variety of energy drinks available, which can be bought not only in convenience stores and supermarkets but also from vending machines that can be found in every corner of the city.

Energy drinks that are available at vending machines dotted around the city include even Red Bull and Monster Energy Drinks, and what I introduce here Otsuka Oronamin C Drink is also among them.

The Oronamin C Drink produced and sold by Otsuka Pharmaceutical is not a drug but a classical carbonated soft drink that has long been loved in Japan. It was introduced in 1965 and comes in a 120 ml dark brown glass bottle.

 The red and white old-fashioned logo design has hardly changed over the past decades, by which most Japanese people can instantly recognize the product.

The slogan of it “Genki Hatsuratsu (元気ハツラツ: alive and kicking) Oronamin C” is also very famous and can be heard in the TV commercial.

How to Open

As you can see in the video, the bottle can easily be opened by pulling up the tab and removing the lid. The energy drink inside is clear brilliant yellow in color and has the right amount of fizz.


Otsuka Oronamin C Drink is sweetened with sugar, high fructose corn syrup, and honey, and not chemically sweet. The Japanese energy drink has a fruity note that everyone can like and is very easy to drink.
