History of IINO LINES

The history of IINO LINES can be traced back to 1899, when the founder Torakichi Iino began transporting coal by barge at Maizuru Port, Kyoto Prefecture. Despite the curtailment of the business during the Second World War and again as a result of the major consolidation of Japan’s shipping industry in 1964, the IINO Group has contributed to livelihoods, industry, and society through two distinct businesses: the Shipping Business focusing on the transport of resources and energy and the Real Estate Business engaged in office leasing.
