Tokyo Vice is not a true story. It's a made-up tale crafted by the creators' imagination and storytelling skills. Though it may give the impression of reality, it's all fabricated for entertainment purposes.
To some extent. While it's not a direct account of one specific true story, it incorporates elements and themes drawn from real-life situations in Tokyo's criminal underworld.
Tokyo Vice is based on the real - life experiences of Jake Adelstein. He was an American journalist who worked in Tokyo and got involved in covering the seedy underbelly of the city, including the yakuza and other aspects of the criminal underworld.
