Overcast grey skies and biting winds greet me as I arrive at Tokyo's Narita Airport. Half an hour later, we find ourselves in the city's historic core, driving past the Imperial Palace—once the seat of the 16th-century Tokugawa shogunate and still the residence of the Emperor today. Ahead of us, a swirling mass of people crosses the road, huddled under clear plastic umbrellas. Evidently, a little November rain does nothing to deter the twelve million people who throng the streets of this magnificent city daily.
