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.

01 Morning reset A clean, fresh start before the day gets loud.
02 Skin feels cared for A softer rinse for face, hands, body, and bath time.
03 Evening unwind A small Japanese-inspired ritual that helps home feel calmer.

Visible results,
inspired by the science of carbonated springs

When CO2 dissolves in warm water, it is gently absorbed through the skin. It is the secret behind Japan's famed carbonated hot springs, and Nagayu brings that experience into your everyday shower.

01 Boosts microcirculation Carbonated water temporarily widens the tiny blood vessels near the skin's surface and speeds up circulation, leaving skin warm and naturally flushed after your rinse.
02 Clean, never tight Fine bubbles help lift away excess oil and dead skin cells. Skin feels fresh and hydrated, not dry or tight like it can after a plain water rinse.
03 Relax body and mind Japan's carbonated hot springs have long been enjoyed for soothing tired muscles and unwinding after a long day. Bring that calm into your shower.
04 Gentle on skin A mild pH with no alcohol or artificial colorants. Gentle enough for sensitive skin and easy to add to your daily routine.

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.
