Are Japanese people hard-wired to hoard?Last week’s earthquake and tsunami has engendered a nationwide run on retailers that has alarmed the authorities. Even in Hiroshima, which was totally unaffected by either catastrophe and isn’t in a related earthquake zone, people are said to be stripping store shelves of batteries. Renho, the Democratic Party of Japan superstar who heads the consumer affairs ministry, blasted the mentality that has led to this behavior, saying that she could understand why people might want to buy batteries and portable cookers and even bicycles, but “natto and chicken”? She stressed that it causes shortages of much needed supplies to the afflicted areas and used the word kaishime to describe these actions, which means to “corner the market,” except that she isn’t talking about companies, but individual consumers. In that regard it seems an imprecise term, but the negative connotation is what’s important.
