We started the business of no flat tires so called “No-Pan tire’” by Repair-M
Gel over 10 years ago.
The Repair-M shop which performs Repair-M Gel injection processing has spread from Hokkaido to Okinawa, about 100 stores throughout the country. A number of no flat tires products have appeared in the world, and one day they went away from the market.
Thanks to you, only Repair-M Gel got a high reputation, We think that this is the result of cooperation of everyone, including shops. I really appreciate it.
We will continue to improve our company's products such as Repair-M Gel day by day without compromising on the current situation. We have just sold Repair-M Gel Super Soft which has greatly improved ride comfort but we are proud that it will meet everyone's expectations.
Would you like to open the Repair-M shop that provides services to
You can open not only in Japan but also overseas. If you are interested, please
contact us.. In the case of abroad, We will carefully teach you how to operate
the equipment by Skype
We always pursue
Our motto is,
Do what people do not do"
We will continue to challenge various fields in the future.
In addition, we will visit our company to be one of the world's leading companies in manufacturing and selling power-saving electric power devices in five years.
Recently, we succeeded in developing a long-lived lead-acid storage battery with a lifespan of more than 10 years, based on which we have developed a programmed smart inverter, which is based on "MassTech Energy “Anshin’”(safety) System (M-EAS)" and "Long Lifetime Maintenance Free batteries ", and advanced to the electric power field.
We will continue to create this unique thing for the development of Japan without forgetting this initial intention. Moreover, the place of our activities will not stay in Japan, have a global perspective, and will expand rapidly overseas. I would like to ask for your continued guidance and encouragement in the future.
