This is a fascinating history of my go-to summer drink in Japan. I’ve drunk gallons of the stuff, but had no idea how it came about.
“Nearly 50 years ago, an Otsuka researcher named Rokuro Harima was on a business trip to Mexico when he was hospitalised due to diarrhoea. The doctor told him to make sure that he got enough water and nutrition, but just gave him a regular carbonated drink,” he says.
“This led Harima to think how much better it would be if he had an easy-to-drink beverage that could supply both the water and the nutrients that he needed. Later, Harima saw a doctor drinking a pouch of IV solution to rehydrate himself after finishing surgery, which gave him the idea for a drinkable IV solution.
