Saving the world.
Providing a new solution for hand washing.

Hand washing is the most efficient and inexpensive way to stop the spread of germs.
However, people can only wash their hands in a limited number of places.
In developing countries, for example, three billion people are unable to wash their hands due to a lack of water supply infrastructure.
WOSH is an innovative solution for hand washing that provides cleanliness and comfort anywhere and anytime.
It features our unique water circulation technology, which we originally developed for showers and other products deployed during disasters.
The New Normal for hand washing. The Next Level of public hygiene.
Making the world more sanitary and pleasant.


Keep your hands and your phone clean with our technology.
We provide a safe and secure environment.

To ensure the safety and quality of the water supply, WOTA uses a unique 3-stage technology: membrane filtration, chlorine addition, and deep ultraviolet irradiation.
The quality of the supplied water is completely hygienic and complies with the WHO drinking water guidelines and the national drinking water standards of each country.
It is also equipped with deep ultraviolet radiation feature for smartphones, which kills more than 99.9% of bacteria from the surface of the phone within 20 seconds while washing your hands.

    We've incorporated upcycling.
    Drum housing design

    The case is made of a drum that is designed to be environmentally friendly.
    By upcycling both water and drums, we are proposing a new way of manufacturing in a recycling society.


Safety and security for a wide range of customers from restaurants to retail stores.
The design is based on a drum and will blend in with any space.


    It is placed at the entrance to protect the safety and security of employees and visitors.


    In places for eating or drinking, we ensure hygiene at the entrance. We make sure that customers can enjoy their meals and employees can feel safe.

  • SHOP

    By placing the hand-washing stations at the entrance of a store or a shopping center before people touch the products, customers can enjoy shopping with a peace of mind.


    In beauty salons and nail salons where face-to-face contact is unavoidable, customers are asked to wash their hands when they enter the salon.
