The series has also been animated by Toei Animation, first as a feature film, with Kappei Yamaguchi as the voice of Kindaichi, released in 1996 and then a television series, with Taiki Matsuno voicing Kindaichi in this and subsequent productions for 148 episodes from 1997 to 2000, and there has since been a live-action film, four live-action drama series, three live-action television specials and further animated features for cinema and television. A new anime television series adaptation, titled The Kindaichi Case Files R (Returns), began airing on April 5, 2014 and concluded on September 27, 2014. The voice actors of the main characters from the first anime television series reprise their roles. A second season began airing on October 3, 2015.
The collected stories are published in English by Tokyopop with the title The Kindaichi Case Files. Only the first 17 volumes (the first series) have been released by Tokyopop. The series is airing on Animax Asia as The File of Young Kindaichi in Japanese with English subtitles.
Kindaichi mysteries are whodunnit stories featuring (usually multiple) gruesome murders, often with a supernatural tinge. They are typically of the style of John Dickson Carr, and frequently feature a locked room mystery or other seemingly "impossible" crimes, such as a murder occurring when all surviving suspects have (apparently) airtight alibis.
A notable distinction of The Kindaichi Case Files is that the killers are not depicted as psychopathic murderers and the murders are never committed for financial reasons alone. The identified killers all have deep rooted problems, often involving great emotional trauma through the greed or thoughtlessness of others, as their reasons for committing the murder(s). Thus the killers are often portrayed as sympathetic figures, as opposed to cold, calculating killers in some other mystery series.
In addition to this, after being revealed the criminal usually attempts suicide.
