TV drama
The first TV series broadcast on TV Asahi's "Friday Night Drama" slot from July 4, 2003 until September 19, 2003, and garnered an average rating of 12.0%, reaching a high point of 14.1% according to the Kantō Area Video Research group, the highest rating of any show in the "Friday Night Drama" slot. During the final episode of the first series, viewers were told that Tadano and Moriwaki were going to take a 15-month vacation traveling around to various onsen across Japan. A special titled Tokumei Kakarichō Tadano Hitoshi Returns was aired on December 22, 2004, just over 15 months since the final episode of the first series.

On January 14, 2005, the second series began airing, running through March 18, 2005. According to the Kantō Area Video Research group, the series achieved a 16.0% rating with the episodes airing on February 11 and February 18. The final episode garnered a rating of over 20% in its timeslot, due largely to the main character, Tadano, collapsing during the episode due to being overworked. On August 7, 2005, the second special was aired, titled Nerawareta Serebu na Onna-tachi. The special garnered a 19.3%, the second highest rating ever for a drama, and making it the most popular drama aired between August 1 and August 7.

The third series began airing January 12, 2007.

While in the original manga Tadano is a "lone wolf", in the TV series he works in combination with Moriwaki, a character created for the TV series. Moriwaki has now made his appearance in the original manga.
