In the context of the frozen food (processed food) distribution system with mass food market companies at the tail end, this paper identifies, in the wake of the 2011 earthquake disaster, what information influenced individual players' actions and what caused product shortages, while pointing out the problems associated with the distribution system. Through analysis of interviews with sampled companies, the materials provided by individual food companies and the financial statements provided by a leading frozen food manufacturer, the following points were revealed. First, in the distribution system where the sample companies belong at the tail end, information was transmitted along the value chain: i.e., raw material supplier (including non food material) → food manufacturer → middle-sized food wholesaler → mass feeding companies → agencies (in some cases) → food consumer. Second, the cause for the disaster-induced stock-out was multifold, consisting of seven conjoining factors, some of which are not directly related with manufacturing: damage to production facility, logistics, gasoline supply, electricity outage, planned outage, shortage of raw materials, and shortage of packing materials. Third, the existing distribution system remained to possess part of its capability of covering the mass feeding market in the metropolitan area comprehensively when the disaster took place. On the other hand however, food manufacturers incurred substantial damage, which indicates their fragility and constitutes the problems with the distribution system. In a bid to alleviate these problems, this paper suggests formation of upstream value chains, rather than the current concentration in a particular region (or multiple regions) and on a material-by-material basis.
