MegRhythm

MegRhythm is a Japanese wellness brand owned by Kao Corporation, known for creating self-heating products that promote comfort and relaxation. The brand focuses on relieving everyday fatigue, especially from long hours of work, screens, and travel.

Their most popular item is the Steam Eye Mask, which warms to a gentle 40°C upon opening. The mask releases soothing steam that helps ease eye strain, tension, and tiredness, making it a favorite for bedtime routines, flights, and post-work relaxation.

MegRhythm also produces self-heating neck, back, and belly warmers, all designed to support circulation, relaxation, and stress relief. The name combines “meguri” (circulation) and “rhythm,” reflecting the brand’s goal of restoring balance and comfort.
