A prominent member of the business community, Mitsuji Kasamoto was an executive officer with the Hilo Japanese Chamber of Commerce and Industry, an organization that worked to expand commerce with Japan, eliminate trade barriers, and develop direct steamship service between Hilo and Asia. All of JCC&I's prewar senior executive officers were interned. Along with Kasamoto, they included Yoichi Hata, Kashin Isa, Hisato Isemoto, Katsujiro Kagawa, Masato Kiyosaki, Gunichi Kuwahara, Genichi Nagami, Eikichi Ochiai, Takaichi Saiki, Takuji Shindo, and Shizuma Tagawa.
