  • *
    Formerly, DAIICHIKOSHO had a privately managed business known as HOSHI SHOTEN. It was founded in March 1971 in Chofu City, Tokyo, as a distributor of audio equipment. The business expanded substantially, and in February 1976, we took over an inactive company called NITTO INC. (founded in April 1973), and changed the business objectives and the name to DAIICHIKOSHO CO., LTD., and began business as a corporation.
