In the Inter-War period, while “tramp shipping” was declining world-wide, Japanese tramp shipping developed remarkably well. This development was due to diversification in operating services, that was the development of “tramp linerization”.
This is an analysis paper of the start of liner services and its development by tramp shipping enterprises-examining under what managerial environmental and cooperate strategies, this progress was made and maintained-through a case study of “MBK's Senpakubu” (Mitsui Trading Co's Shipping Div.) as a representative of the general merchant operator. The conclusions of this analysis are as follows :
First the liner services by Senpakubu made a good start under circumstances in which there was suitable world-wide information and a trading network provided by the Bussan Co. But secondly, being an auxiliary unit of MBK's business, Senpakubu was requested to act on the whole organization's agreement in decision making, which sometimes reduced the strategic time horizon of Senpakubu's business. Thirdly, however, Senpakubu's strategy changed into soliciting a various or a wide range of different cargoes, loading more “Shagaini” (other shipper's cargoes) than “Shanaini” (its own cargoes) by steadily building a superior fleet, with which Senpakubu succeeded in new developments from an auxiliary unit into an autonomous functional operating unit within MBK's trades.
