What Nagayu is
A ritual made for the shower you already take
Nagayu pairs Japanese CO2 BeautyTab tablets with the Supercharge Deluxe shower head to create a gentle carbonated rinse for face, hands, body, shower, or bath time.
A better everyday rinse
Make the shower feel like the part of the day you keep.
A daily shower can do more than rinse. Nagayu turns ordinary moments into a softer, calmer pause: the first shower, the after-work cleanse, the quiet evening bath.
How it fits your shower
A simple ritual, without extra routine.
Use Nagayu after your usual cleanse, as the final rinse of your shower or bath. Warm water activates the tablet, then the carbonated flow becomes a quiet last step for skin, body, and hair.
STEP I
Place the tablet
Set one CO2 BeautyTab into the Supercharge Deluxe tablet recess.
STEP II
Rinse & Feel
Watch the bubbles dance across your skin, then sink into the deep relaxation of a carbonated spa rinse.
STEP III
Dry & Relax
No need to rinse again with plain water. Simply towel dry to complete the full carbonated spa care ritual.
Before you buy
The essentials,
kept simple.
A small ritual should be easy to understand before it enters your bathroom. These are the details most people usually check before choosing a kit.
