Japan Tobacco and Japan Airlines trial ‘Chupica’ waterless mouthwash tablets with cabin crew

Japan Tobacco (JT) and Japan Airlines (JAL) conducted a proof-of-concept trial of the mouthwash tablet “Chupica.”

“Chupica” is a tablet that doubles as toothpaste and mouthwash, keeping the mouth clean without water. Trial sales in the general market began in September 2024. Its predecessor, “mouthpace,” has flown to the International Space Station four times, and since August 1 it has also been carried on astronaut Yui’s long-duration mission.

The trial involved about 100 Japan Airlines cabin crew members. They used “Chupica” during rest periods on long-haul flights exceeding six hours and while staying at overseas destinations. A user survey evaluated convenience and effectiveness, with the findings used to identify needs onboard and during overseas stays and to inform product development.
