Hours after the first shock waves hit, several of the largest crime groups in the Japanese mafia, opened their offices to those stranded in Tokyo, and shipped food, water, and blankets to the devastated areas.

The Inagawa-kai (the third largest organized crime group) sent twenty-five trucks filled with diapers, ramen, batteries, flashlights and drinks to the Tohoku region.

The Sumiyoshi-kai (the second-largest crime group) offered refuge to members of the foreign community, which is unheard of amongst the right-wing yakuza.

The Yamaguchi-gumi (largest crime group) opened its offices across the country to the public, and is very quietly sending truckloads of supplies.
