The Nagayu
CO₂ Micro Bubble
Shower System
The same spa-grade technology used in luxury human wellness centers — now available for your dog. Nagayu's CO₂-infused micro bubble bath delivers a level of clean that no standard grooming salon can match.
Science-Backed Bathing Technology
Nagayu is a Japanese-engineered shower system that infuses water with carbon dioxide (CO₂) to produce billions of ultra-fine micro bubbles. Originally developed for human therapeutic use in hot springs and medical spas, this technology has been adapted for professional pet grooming — and the results are extraordinary.
CO₂ Infusion
Carbon dioxide is dissolved into the water stream at the shower head, creating a supersaturated solution.
Micro Bubble Formation
As the CO₂-rich water exits, billions of micro bubbles form — each 1/1000th the size of a standard water droplet.
Deep Skin Penetration
These tiny bubbles are small enough to enter skin pores, lifting out dirt, bacteria, dander, and odor from within.
CO₂-Infused Micro Bubbles
Nagayu technology dissolves carbon dioxide into water, creating billions of ultra-fine micro bubbles that penetrate deep into the skin and coat — far beyond what a standard shower head can achieve.
Deep Pore Cleansing
The micro bubbles are smaller than skin pores, allowing them to enter and lift out embedded dirt, dander, allergens, and odor-causing bacteria at a microscopic level — leaving skin truly clean.
Soothes Skin & Reduces Irritation
CO₂-rich water has been shown to improve circulation and calm inflamed or sensitive skin. Ideal for dogs with allergies, hot spots, dry skin, or post-shave sensitivity.
Neutralizes Odors at the Source
Rather than masking odors with fragrance, Nagayu water eliminates odor-causing bacteria and residue from within the coat — your dog smells fresh longer after every bath.
Softer, Shinier Coat
The micro bubble treatment leaves the coat noticeably softer, more manageable, and with a healthy natural shine — without weighing it down or stripping natural oils.
Gentle Yet Powerful
Despite its deep-cleaning power, the Nagayu system is incredibly gentle — safe for puppies, seniors, and dogs with the most sensitive skin types.
The Science Behind the Bubbles
Nagayu isn't a gimmick — it's backed by real science and used in wellness facilities worldwide.
- Micro bubbles are 1/1000th the size of a standard water droplet
- CO₂ water has a slightly acidic pH that matches healthy dog skin
- Proven to reduce skin bacteria by up to 99% in clinical studies
- Used in human spas and medical-grade skincare worldwide
- Improves blood circulation and promotes healthier skin cell turnover
- Leaves no chemical residue — just pure, clean, oxygenated water
Why It Matters for Your Dog
Dogs have sensitive skin that's easily irritated by harsh chemicals, rough scrubbing, or incomplete rinsing. Nagayu changes everything.
For Allergy-Prone Dogs
The deep-cleansing micro bubbles remove allergens, pollen, and environmental irritants that get trapped in the coat — providing real relief for itchy, reactive skin.
For Senior Dogs
Gentle CO₂ water improves circulation and soothes aging joints and skin without any harsh scrubbing or chemical exposure.
For Show-Quality Coats
The micro bubble treatment leaves coats exceptionally soft, clean, and manageable — making styling easier and results more impressive.
For Anxious Dogs
The warm, gentle micro bubble bath has a naturally calming effect — many dogs visibly relax during their Nagayu treatment.
