During the 1800’s, Commodore Perry introduced lemonade to Japan. The Japanese people loved it so much that it became an iconic symbol for Japanese soda. The Japanese mispronunciation of the word lemonade became Ramune. Ramune's unique codd-neck bottle is its most well-known feature. Instead of a traditional bottle cap, the marble acts as the bottle cap. The carbonation from the soda pushes the marble upwards forming an airtight seal with the rubber seal. The flavors of Ramune started as lemon-based but over time evolved to become its own unique taste.
