That's a lot of cocaine. According to Japan's Fuji Network News, a local in the city of Yokosuka discovered four backpacks packed with the drug.
Each bag contained about 20 bricks of cocaine, wrapped in plastic and weighing one kilogram each.
In total, there were 80kg of coke. With a street value of ¥4.8 billion ($48 million), this the biggest illegal drug seizure in Japanese history.
