Everyone else is writing tell-all books, so why shouldn't the daughter of a yakuza (Japanese mobster)?
For an excellent first-hand account of what life was like for the yakuza in the days when they made their living solely on illegal gambling, I highly recommend Confessions of a Yakuza.
Daddy's little girl shows off some of her full-body tattoos. Tattooing in the yakuza goes back to the tradition—inherited from China—of tattooing criminals as a way of literally marking them for life. Tattoos also served the purpose of ensuring loyalty: Once you were marked like that, no legit employer would ever hire you. Even today, most onsen (hot springs) and public baths have "NO TATTOOS" signs at the entrance.
