Plot Synopsis

Would you like to meet a ghost?

Michi (Kumiko Aso) and her friends work in a rooftop nursery, caring for potted plants and running the business. When her colleague, Taguchi (Kenji Mizuhashi), stops coming to work and refuses to answer his phone, she drops around to see how he's doing, only to witness his shocking suicide. All over Tokyo, people are being lured to their death by a strange website, promising contact with ghosts. One by one, Michi's friends and relatives succumb to this strange phenomena.

Meanwhile, we meet Kawashima (Haruhiko Kat), an internet newbie who is having trouble making sense of the strange images he is seeing on his computer. Puzzled, he seeks help from programmer Harue (Koyuki), who initially believes it to be the work of a hacker. Soon, they realise a link exists between the declining population and the strange, ghostly images on the internet. Kawashima learns of The Forbidden Room, a place sealed with red tape that houses souls who spill into our world from the drastically overcrowded place they belong. Eventually Michi and Kawashima cross paths and aim to help each other survive mankind's impending holocaust.

Kairo (Pulse) poses the thought that the afterworld (or heaven, if you like) has a finite space and is only capable of a certain number of inhabitants. If the space were to fill, where would the remaining ghosts go? Initially, they occupy a room sealed with red tape inside a derelict building, but when the building is demolished the spirits find a new space to occupy: the internet.

This film was produced way back in 2001 and has been a long time coming in Region 4. I initially sat down to review this disc thinking I'd never seen the film before, but it turned out I had, some years ago. I must say that I enjoyed it a great deal more this time around, having only seen it with a stereo soundtrack last time. The sound design and score for this film are stunning and generate the majority of the tension, so a simple stereo soundtrack is quite a drawback. Thankfully, we have the full surround experience available here. Interestingly, an American remake, Pulse (2006), has already been released on DVD in Region 1, and has received mixed reviews to say the least.

Written and directed by Kiyoshi Kurosawa, Kairo (Pulse) is essential viewing for fans of Japanese horror. I would describe it as a blend of Ju-on, Ringu and, strangely enough, The Omega Man, with a unique style and inspiring atmosphere.

Transfer Quality


Reviews of this film's transfer to DVD are similar across all Regions, citing a very dark image and average visible detail. Ours is no different.

The feature has been transferred to DVD in an aspect ratio of 1.78:1, complete with 16x9 enhancement. The image is tight to the frame on all sides. I presume this would be relatively close to the film's original theatrical aspect, in fact the matte may have been opened a little from the original 1.85:1.

The picture is moderately sharp throughout and shows a mild, yet consistent wash of film grain. Haloing is a major issue, particularly on a big screen. It seems that any foreground object is outlined slightly, which is rather distracting. This effect can also be seen in the opening and closing titles. The film is also very dark, a choice on the part of the director I presume, but I felt that these scenes are handled well and suit the overall atmosphere of the film. There were no occasions where I was struggling to make sense of what was lurking in the shadows.

The film is practically devoid of any bold colouring. Having said that, there are no inconsistencies or rendering issues to speak of.

I didn't notice any MPEG compression issues at all, however the video bitrate appears to be highly variable. Some film artefacts are present, ranging from small specs here and there to a particularly large one at the bottom of the frame at 30:00.

An English subtitle stream is activated by default. The yellow font is easy to read and is paced accurately with the dialogue. The font switches to white to translate Japanese characters that appear on screen. I didn't notice any annoying spelling or grammar errors in the text.

This disc is dual layered, with a layer break placed during the feature at 36:12. The transition between layers was transparent on my system, however, it may interrupt motion on screen for some.

Film Artefacts


There are two soundtracks accompanying this film on DVD, both of which are the film's original Japanese language. A nice Dolby Digital 5.1 soundtrack is the default, encoded at 448Kb/s. A Dolby Digital 2.0 stereo (224Kb/s) option is included.

The dialogue is distinct and easy to discern above the rest of the elements in the soundtrack. The ADR is absolutely seamless and audio sync is fine.

This film benefits from some amazing sound design, which is served best by the surround audio option. The use of the surround channels ranges from subtle atmospherics and elements of the score to a passing helicopter at 11:00. At 56:24 the rear channels come alive with a creepy voice calling for help, which is very, very effective and ups the scare-factor considerably.

The score by Takefumi Haketa mixes haunting, operatic vocals with some tense percussive passages in places. Otherwise, the score is predominately orchestral and suits the overall mood well. The closing theme Wings is by a pop group named Cocco.

The LFE channel is used to add some bottom end here and there, adding tension in the right places. A crash near the film's finale is served well by low, rumbling effects from the subwoofer.

Featurette- Making Of (38:56)

Much of the footage here was captured on the set during filming, as the director discusses character motivation and movement between takes. There are a few interview segments as well, as Kiyoshi Kurosawa explains his approach with the camera and how he hopes his vision will be interpreted, with other clips from his previous films for reference. This featurette is presented with English subtitles and is not 16x9 enhanced.

A series of stills taken from the film, presented with 16x9 enhancement and accompanied by an audio clip from the score.

R4 vs R1

NOTE: To view non-R4 releases, your equipment needs to be multi-zone compatible and usually also NTSC compatible.

The Region 1 and 2 releases include stereo audio only, which would seriously negate the film's spooky atmosphere. These include the same Making-Of featurette as our Region 4 disc. It's been a long wait, but the local disc is a winner.


Kairo (Pulse) is an intelligent horror film that provides interesting food for thought. Is the film condemning man's dependance on technology, or praising his obsession with spirituality?

The video transfer is good, but lacks fine detail.

The audio transfer is great.

The extras offer some valuable insight into the production.
