How it started
History
Nippon Sanso was first established in 1910 as the Nippon Sanso joint-stock company and formally founded as the Nippon Sanso Corporation in 1918. In 1989 it acquired Thermos Japan and Matheson (compressed gas & equipment). On 13 May 2014, Mitsubishi Chemical Holdings announced an agreement for Taiyo Nippon Sanso to become an affiliate of Mitsubishi Chemical, a core company within the Mitsubishi group. Mitsubishi Chemical subsequently increased its stake in Taiyo Nippon Sanso to 50.5%. In 2020 the company was renamed to Sanso Holdings Corporation as it transitioned to a holding company.
