> > Beneath the surface of Japan's ultra-sophisticated cities lie the hierarchical ties that have governed this island nation for centuries and that, at moments of crises, invariably reassert themselves. >The former hostages' transgression was to ignore a government advisory against traveling to Iraq. >But their sin, in a vertical society that likes to think of itself asclassless, was to defy what people call here "okami," or, literally, "what is higher." > > Treated like criminals, the three former hostages have gone into hiding, effectively becoming prisoners inside their own homes. The kidnapped woman, Nahoko Takato, was last seen arriving at her parents' house, looking defeated and dazed from tranquilizers, flanked by relatives who helped her walk and bow deeply before reporters, as a final apology to the nation. > > Dr. Satoru Saito, a psychiatrist who examined the three former hostages twice since their return, said the stress they were enduring now was "much heavier" than what they experienced during their captivity in Iraq. Asked to name their three most stressful moments, the former hostages told him, in ascending order: the moment when they were kidnapped on their way to Baghdad, the knife-wielding incident, and the moment they watched a television show the morning after their return here and realized Japan's anger with them.
