Officers of the Metropolitan Police Department seized around 180 kilograms of cannabis with a street value of 720 million yen from a condominium in Tokyo in July 2008.[1][2] Police called it the largest amount ever found in a raid in Japan.[1][2] A 40-year-old Tokyo company executive and a 22-year-old Chinese student were arrested on suspicion of possessing the cannabis for sale.[1]

The seizure came amid a wave of cannabis arrests that put marijuana on Japan’s front pages in 2008, drawing in students, suburban householders and sumo wrestlers.[2]
