A Japanese biker who saw the viral tweet on Twitter of the live-streamer harassing people on a Japanese train recognizes him in real life and confronts him and asks him to repeat what he said about Hiroshima and Nagasaki.
The live streamer had said America will bomb Nagasaki and Hiroshima again if the Japanese people don't behave. He harassed a carload of people on a Japanese train until an American-Korean man stood up to him.
