In 2004, according to a spokesperson of Metropolitan Tokyo, there were more than 1,000 yakuza members in Kabukichō, and 120 different enterprises under their control.

Entering the new millennium, laws were more strictly enforced and patrols became more frequent.
In addition, fifty closed-circuit cameras were installed in May 2002 after the Myojo 56 building fire that killed 44; the patrols and cameras reduced criminal activities in Kabukichō, amidst controversy.

Private citizens and government agencies launched a joint effort in July 2003, called the Shinjuku Shopping Center Committee to Expel Organized-Crime Groups, with the aim to replace unlicensed and adult-oriented businesses (which were believed to pay protection fees to organized crime groups) with legitimate businesses.
In 2004, the police undertook an operation clamping down on illegal clubs and brothels, causing many to go out of business.
An amendment to the 1948 Adult Entertainment law made aggressive catching of female patrons by male hosts illegal.
Also, the Kabukichō Renaissance organization started in April 2008 to rid Kabukichō of the yakuza; office manager Yoshihisa Shimoda stated "[a]t the end of the day, we want Kabukicho to be clean.
We want security, safety and a pleasant environment."

In 2011, Tokyo began to enforce the Organised Crime Exclusion Ordinance, which makes it a crime for businesses or individuals to deal with the Yakuza.
Although the punishment for violating the ordinance ranges up to one year in prison and a fine of ¥50,000, it is intended to provide an excuse for refusing to make protection payments.
