Asahi began selling their Oishi Mizu Tennensui Sayu in convenience stores and supermarkets in Japan as an alternative to grabbing a bottle of green tea or a can of coffee from the heating rack.
Oishi Mizu Tennensui Sayu isn’t a clear, non-carbonated soda-style flavored water that started gaining popularity
The piping-hot bottles are simply filled with the same mineral water that Asahi usually sells at cold or room temperature.
According to Asahi, a growing number had been craving hot water on late-autumn and winter mornings as a way to warm themselves up without caffeine’s side effects brought by coffee or tea.
Orange caps on the Asahi bottles indicate that the drink, under Japanese beverage-handling regulations, is only to be sold hot.
Asahi Oishi Mizu Tennensui Sayu is priced at 105 yen.
