We, a leading manufacturer with an around 40% share in the Japanese industrial gases market, have been producing safe, reliable, and high-quality industrial gases throughout Japan since its foundation in 1910, and under the brand of Taiyo Nippon Sanso since 2004. We have expanded our business by providing the various effects and benefits of these gases.
