Being the red light district and having a bad reputation in Tokyo, Kabukicho does not begin to compare to bad parts of town in other countries. As red light districts go this is a fairly mild and safe one so worry not, as I guarantee you are at no risk of getting robbed or harmed. Definitely visit at night to witness the area come alive and see all the lights from the numerous pachinko parlours, arcades, eateries, bars and sex shops in the area. Also look up to notice Godzilla on the roof of Toho Cinema. Robot Restaurant is also a crazy once in a lifetime experience. Golden Gai with its countless bars is also nearby. Overall one of my favourite areas in Tokyo. Minus one star for the rats.
