Walking among the open air cafés in Tokyo during an unseasonably warm November last year—just after the Paris terror attacks—I realized that something was different. Japanese almost never think twice about going into public places. Their streets are not filled with combat troops on wary patrol. Parents don’t fear when their children congregate at a concert or in the park.
Japan is notoriously strict with immigrants, making it very difficult for non-ethnic-Japanese to live in Japan.
