We visit the incredible neighborhoods of Akihabara and Shibuya in Tokyo to see what the city looks like at night. We play some Tekken and go shopping for nunchuks before visiting the famous jiu-jitsu gym Paraestra, founded by MMA and BJJ legend Yuki Nakai. We see World Champion Rikako Yuasa training and catch up with British black belts Samantha Cook and Bradley Hill.
