Who is Sumitomo?

=> Sumitomo is a Japanese group of companies with a total of approximately 480,000 employees. Its roots date back to the 17th century, when Masatomo Sumitomo founded the company in Kyoto and established the corporate philosophy that is still valid today: Banji-nissei, Shinyo-kakujitsu and Fusu-furi. Loosely translated: Work constantly on yourself, pursue sustainable and honest business.
