The series is created, directed and written by Mitsuo Iso, it aired for 26 episodes in Japan on NHK Educational TV between May and December 2007.

It has received high praise among critics for its fusion of old-fashioned Japanese scenery and urban legends, a modern version of the Japanese folklore Kaidan, with a futuristic worldview, and for its story of children playing in an augmented reality world using a device called "Den-noh Megane" (cyber glasses), as if anticipating the subsequent emergence of smart glasses.

At her new school, Yasako meets a group of children with rich personalities and experiences a series of strange events that occur in the Den-noh space.

Den-noh Coil is an anime about children growing up in the near future, when semi-immersive augmented reality (AR) technology has just begun to enter the mainstream.

[6][7] The series takes place in the fictional city of Daikoku, a hotbed of AR development with an emerging citywide virtual infrastructure.

Due to the animators involved in its production and its unusually high-profile television broadcast time slot, Den-noh Coil was highly anticipated.

[8] The theme of Den-noh Coil using AR technology in mysterious stories and urban legends such as Illegal, Michiko, and "the other side", and above all, "people's feelings and memories" associated with "places".

[9][10] "The other world" visualized by Den-noh glasses is a form of "the past" that has not been updated to the present, a metaphor for the "memories" and "remembrances" that people leave behind in places and sometimes, people are unable to break free from the past and are attracted to "the other world" (Isako, who cannot accept her brother's death, and Haraken, who runs after the shadow of Kanna died in an accident).

[15] Australian distributor Siren Visual released the series on streaming in July with English subtitles, and on DVD in September in 2011.

[1] Anime News Network praised the series for its unique concepts, story, animation and technology, describing it as "Concepts that are years ahead of their time, engaging characters and story, good use of CG with strong character development, engaging mysteries, tense and thrilling action sequences".

"[31] John Hanke, former head of Google's Geo Product division, founder of software company Niantic, Inc. and creator of Ingress & Pokémon Go, is a fan of Den-noh Coil and Ghost in the Shell.

At the time, with the Second Life boom that occurred around 2006, there was a lot of talk about a virtual society, but in Europe and the U.S., the idea of creating a completely different world where people could do whatever they wanted, like the metaverse in the science fiction novel Snow Crash.
