The worst of times sometimes brings out the best in people, even in Japan’s “losers” a.k.a. the Japanese mafia, the yakuza.
Hours after the first shock waves hit, two of the largest crime groups went into action, opening their offices to those stranded in Tokyo, and shipping food, water, and blankets to the devastated areas in two-ton trucks and whatever vehicles they could get moving.
The day after the earthquake the Inagawa-kai (the third largest organized crime group in Japan which was founded in 1948) sent twenty-five four-ton trucks filled with paper diapers, instant ramen, batteries, flashlights, drinks, and the essentials of daily life to the Tohoku region.
