Ugly Americans by Ben Mezrich

An entertaining story about a group of hedge-fund cowboys taking place in Japan. Somewhat fictionalized as some of the events and places do not match the actual facts. (I know because I am born and raised in Tokyo)

The main character, "John Malcom", is a Princeton graduate who goes to work for "Dean Carney" for Kidder Peabody located in Osaka, Japan. After the scandal of Joseph Jett and Nick Leason, he then goes to join Carney's hedge fund ASC.

A good page turner that involves money, sex, Yakuza mobs, and romance. The book takes a look inside the Japanese underground known as the Water Trade. This refers to the sex industry/business which is mainly mob run.

If you are looking for a quick entertaining read on hedge-fund cowboys making a fortune trading the Nikkei, I recommend it. I finished this book in a day and found it to be good page turner.
