Less allergies - Less contamination risk - More safety


For nurseries, kindergartens but also at home, the GUNMA ball is  the toy which increases the safety and limits the contagion risk among toddlers.


Dedicated to toddlers, the self-cleaning ball GUNMA is made of an innovative photocatalytic material which permanently cleans the ball surface.


90% of bacteria disappeared with natural or artificial light according to JIS R1702  - Test method for antibacterial activity of photocatalytic materials and efficacy.


Mouth diseases transmission risk as any kind of contagion are reduced almost to zero when using the GUNMA balls.


Colorful, soft, bouncing like a traditional ball, the ball GUNMA is used like any ball while decreasing the risks of contagion and allergy.


With an integrated internal inflation valve, the pressure of the ball is adjustable so that it has a low rebound and is soft for indoor use or higher rebound for outdoor or ball pool if more air pressure in the ball.


Perfect for ball pools to reduce the risk of contamination by its bactericidal and virucidal effect.

Composition :
1 set is made of 16 x 1 pink, 16 x 1 blue and 16 x 1 yellow photocatalytic self-cleaning balls (total 48 balls) with a diameter of about 7 cm - 2.75 inches with GUNMA-CHAN character.



Net in carton box.

Decontamination pack

SKU: 503 X 16
  • Gunma ball can be used indoor or outdoor like a usual ball.

    In a ball pool, the Gunma ball will naturally cleans the other balls.

    Use about 3 Gunma balls for 8/12 usual balls. 


    About GUNMA ball:

    GUNMA has been developped in Japan by a scientist and engineer team

    Manufactured according to European and Japanese safety regulations, this self-cleaning ball GUNMA contains no phenol, no cadmium, no phtalats according to European Directives and also has no poisonous material as per the Japanese Food Safety Law (JFSL) and ST safety standards.


    What is photocatalysis?

    The application of photocatalysis was discovered in Japan by Professor Akira Fujishima at the University of Science in Tokyo in 1967 and of which he is the current president.


    It is naturally in Japan that the first industrial implementations using the process were developed in the 1990s.


    Photocatalysis activates an element called semiconductor using light energy and using the natural humidity of the ambient air in order to facilitate the reaction.


    Activation by light triggers a catalysis (of ancient Greek κατ?λυσις Katalysis, which means to detach).


    An electron is thus emitted and will serve as a "cleaner" on the desired surface.


    Depending on a natural or artificial light source, photocatalysis is therefore a permanent mechanism, with a long lifetime and without much variation.


    Photocatalysis can destroy bacteria, certain viruses, mites, pollens and certain odors.


    The challenge has been to obtain a composite material which can be molded easily and for industrial production, be compatible with tests for tearing and destruction according to current standards (resistant to scratches, bites, etc.), non-toxic, accepting non-toxic cleaning products used by communities while having photocatalytic properties.


    Developed in the Japanese province of GUNMA more than 10 years ago, the self-cleaning balls carry not only the name of the province where they were born but also GUNMA-CHAN, mascot of the province born in 1994 and sacred mascot champion in Japan in 2014.


    What is a joucament?

    The joucament - a contraction of the word 'jouet" (toy) and "médicament" (medication) in French language - differs from a therapeutic toy because it is not signifying in the psychiatric sense, does not have the function of correcting or helping to correct a particular disorder , is also not intended for Special Education Needs, but has features to prevent or alleviate the consequences of a pathology.
