About
S-CUP is the flagship energy drink of the SS Pharmaceutical Company, a company which has its roots in the Edo Period, when Shirai Shosuke founded the "Minoya Yakubo" Kampo(traditional Chinese medicine) pharmacy in 1765. Later in the early 20th century, the name "SS", which stands for "Social Service" was adopted. Today, it also stands for "Science & Society". The company was acquired by German pharmaceutical company Boehringer Ingelheim in 2001.
