He has a cameo appearance in case 4, and is from the popular Japanese TV series "Confidence Man JP."

Self-styled “Japan's greatest swindler” Makoto Edamura is mainly targeting elder people and occasional foreign travelers. But when he tries to scam an apparently clueless French tourist in Tokyo, he can't possibly imagine that what looked like just another ordinary job is going to take him all the way to Los Angeles, tied upside-down on the famous Hollywood sign… And he is yet to find out what fate awaits him!
