In the United States, police precincts look increasingly like military compounds: razor wire, tinted glass, bulletproof barriers, and heavy cruisers. The connection between the officer and the neighborhood has withered into mutual suspicion. In Japan, law enforcement centers around the Koban, a tiny two-room neighborhood police box sitting directly on street corners. Its front doors are made of clear sliding glass and are always open to the sidewalk. Inside, two officers sit at a wooden desk with a map book. They don't patrol in armored SUVs; they ride heavy utility bicycles equipped with baskets and bell chimes. Watch them for thirty minutes on a Tuesday afternoon. They aren't writing citations or frisking teenagers. An eight-year-old girl walks in because she dropped her ten-yen coin down a storm drain; the officer squats down, takes out a magnetic rod, and retrieves it for her with a salute. An elderly gentleman stops by just to ask which train platform goes to Yokohama. The officer steps outside onto the pavement, points with his white-gloved hand, and bows deeply. The police officer is not an occupying force; he is the town's most trusted neighbor. This was how American law enforcement once imagined itself, preserved without cynicism across an entire archipelago.
