A-ARK delivers next-generation antibacterial, deodorizing, and anti-mold nano coating. Effective even in complete darkness — one application protects any space for up to 2 years.
Think of it like sunscreen for your room — except it never washes off, works in the dark, and kills bacteria, viruses, and mold on contact. One visit from our team. Protection that lasts up to 2 years.
We spray an invisible nano-coating onto every surface — walls, ceilings, furniture, AC units. It bonds permanently at the molecular level and continuously breaks down harmful microorganisms 24 hours a day, without any chemicals you need to reapply.
While the market fluctuates, our commitment stays fixed. We've served clients for over 5 years with the same transparent pricing — because real quality doesn't need to follow trends.
A proven track record across hotels, clinics, restaurants, and homes throughout Okinawa.
We set our price based on what's fair, not what the market demands. Our clients always know exactly what to expect.
Walls and ceilings are coated at no extra charge. You pay only for the floor area — no hidden fees, no surprises.
*For walls over 3m in height, pricing may change.
Every application comes backed by our guarantee. If it doesn't perform, we make it right — no questions asked.
Tell us your space size in m² and we'll give you an exact price — transparent, fair, and with no obligation. Walls and ceilings always included.

Conventional photocatalysts require UV light to function. A-ARK's FTO (light-free) nano catalyst works 24/7 on walls, ceilings, AC units, furniture — everywhere.
A single A-ARK application delivers five layers of defense — all invisible nano coating.
99.9% sterilization effectiveness proven. Forms a continuous antibacterial surface that eliminates pathogens on contact across every surface.
Targets and neutralizes viral particles on coated surfaces. Ideal for high-traffic areas and environments with elevated infection risk.
Breaks down odor-causing molecules at the molecular level. Permanently eliminates tobacco, pet, and cooking odors — not just masking them.
Prevents mold and black mold growth inside AC units, bathrooms, and humid areas. Especially effective in environments where mold thrives most.
The nano coating forms a hydrophilic layer that repels dirt and bacteria. Surfaces stay clean longer, dramatically reducing maintenance effort.
