Japan is obsessed with rice. And prices have gone ballistic

A little more than a century ago, in July 1918, the wives of fishermen in Toyama began to protest against the export of rice from their prefecture. The unrest, which was triggered by the staple grain’s surging price, then spread across Japan. Ultimately, the so-called rice riots were violently extinguished by 100,000 troops; an action that would in time bring down the government.
