ABOUT

Born

In Yoga, Setagaya, Tokyo

Co-founded MASH with Magnus Alexanderson

FU, MASH’s first collaborative work, was created in 1991, with a grant from the Swedish Arts Council (Statens Kulturråd). For this installation by Sachiko, Magnus composed approximately 30 minutes of electroacoustic music, which served as the foundation for the project. Between 1991 and 1992, FU also included moments featuring a Butoh dancer, a modern dancer, and a violinist. The work toured Sweden, being presented in seven cities, including notable venues such as the Etnografiska Museet in Stockholm and Uppsala Konstmuseum. It was revived again in 2024 as part of Norrköpings Ljud at Norrköpings Konstmuseum.

Trapped (net art, Shockwave)

Archived at Rhizome in 2001, New York.
Composed with sampled images and citations from the Internet, the work probes into the dark psyche of serial killers, challenging viewers to confront the unsettling truths these behaviours reveal about human nature, and poses a thought-provoking question: how can we reconcile with these harsh realities? Trapped was selected for several New Media festivals and exhibitions, including FILE, São Paulo, Brazil (2004), and Ideologia II – Nordic Contemporary Art Biennial, Gothenburg, curated by Fa+ (2003).

Stretched in Dark (video)

This video marks the conclusion of the MASH Video Trilogy, which includes Skin Add Scratch (1995–1996) and White Hall (1997). Stretched in Dark was commissioned by the Swedish National Institute for Concerts, which also selected the entire trilogy for a national tour across eight cities in Sweden. The trilogy has garnered international recognition, with screenings at prominent events such as Not Still Art (White Hall) in New York and Transmediale (Stretched in Dark) in Berlin.

Series of Computer Graphics

Two series of large computer graphics: She Is A Cow and Keeping Up With Tradition. The latter was shown at among others at the Saitama Museum of Modern Art, Japan

Last Meal Requested (net art, Flash)

Archived at Rhizome, New York, in 2003. The work takes up three human rights violations–the Halabja massacre (1988),the beating of Rodney King (1992),and the Taliban’s public execusion of Zarmeena (1999). By juxtaposing them with historical images and narratives, it reveals how the past still penetrates the present. The work was featured in several new media festivals, including the Thailand New Media Art Festival in Bangkok (2004). It was also included in Rhizome’s educational CD-ROM compilation GROK (2006), which introduced internet art to new audiences while providing insights into its cultural and technological contexts. GROK exemplified Rhizome’s dedication to archiving and promoting digital art, serving as a precursor to their later preservation initiatives, such as Webrecorder.

Boop-Oop-A-Doop (video)

Boop-Oop-A-Doop is an observation and investigation of our daily life and plays with 3 different elements: creation of identity, media culture, and our own desire to be somebody else. By taking up two prominent figures in mass media culture, namely Marilyn Monroe and Betty Boop, the work focuses on how these three elements intermingle with one another, re-enforcing each element each time. Combining analogue and digital video techniques, Boop-Oop-A-Doop displays complex imagery in which such historical video synthesizers as Paik-Abe‘s Wobbulator, Jones’ Colorizer and FairLight are traceable. Included in Aspect Magazine DVD compilation vol. 7 Personas and Personalities as well as the Experimental Television Center‘s Experimental Television Center: 1969-2010 DVD Set

Venue : Mixage I, Fylkingen, Stockholm 

The Mundane Impressionable (video series)

The Mundane Impressionable is a video series that explores the magical moment in which the ordinary in our mundane life becomes extraordinary. A forgotten memory of the truth that the life resides in those forgettable moments of human activities.

Flurry (Interactive Sound Installation) produced by the Interactive Institute, Stockholm

Flurry is an interactive installation that centres on the theme of re-experiencing through engagement. Focusing on snow, the project collects people’s memories of snow in the form of voices and sounds. As visitors interact with simulated snowflakes, it triggers either a snow memory or snow sound. These personal recollections are juxtaposed with scientific texts describing the history and properties of snow that runs through the upper corner of the screen. A complex picture of human responses to snow emerges, allowing them to relive their own snow memories while gaining the experience of others that enrich their own experience. The project was produced by curator Björn Norberg and the Interactive Institute in Stockholm. First shown at the National Museum of Science and Technology/Tekniska Museet , Stockholm (2006). Later at Kulturhuset, as part of LARM festival, Stockholm (2007)

Främmande, a.k.a. Where You Stand (sound installation) at Östergötland County Museum, Sweden

Främmande, also known as Where You Stand, is a sound installation created for the Främmande exhibition at Östergötlands County Museum in 2006, by invitation. The installation features two texts, each presenting opposing views on the theme of “främmande” (the unknown, the unfamiliar, the strange, the foreign, guests, etc. in Swedish). These texts are taken from the internet and juxtaposed through the left and right channels of a stereo recording, played through speakers placed on the floor. As you move through the installation, your position determines which aspects of the texts catch your attention, engaging you with the varying perspectives based on where you stand.

​

Game of Freedom (net art)

The work examines the delicate balance of freedom of expression, contrasting its ideals with the devastating consequences of hate speech. By intertwining philosophical citations, imagery from The Poisonous Mushroom, and haunting photographs of the Jewish population during WWII, it presents a profound exploration of freedom’s fragility. Commissioned by netfilmmakers.dk in Copenhagen for the edition Game of Navigation.

N00sphere Playground (interactive sound installation in Second Life) at the National Gallery of Denmark, Copenhagen

Debut in Second Life with interactive sound installation N00sphere Playground in 2007- 2008. The work was commissioned by Tagging Art in Copenhagen with support from the Danish Arts Council. Additional support from Humlab, Umeå University, Sweden. Shown as part of Virtual Move exhibition at the National Gallery of Denmark. The work was later documented as Machinima N00sphere Playground.

[beyond] (interactive audio-visual performance)

The visuals of [beyond] focus on three female Noh theatre performers, filmed in Tokyo in 2006. Traditionally an art form reserved for male performers, Noh theatre has recently begun to recognise the contributions and talent of female performers, whose artistry is both documented and celebrated in this piece. The footage was further transformed using historical video synthesisers at the Experimental Television Centre, adding a layered and experimental dimension to the visuals. The interactive audiovisual elements of [beyond] are linked through a computer program (Max/Jitter, programmed by Sachiko Hayashi) and guided by human perception, creating a flexible yet complex structural composition. The work has been showcased at two prestigious Swedish festivals: Norberg Festival (2010) and Sound of Stockholm (2010).

You Saw Me Tomorrow (gesture-controlled live cinema to EAM music)

You Saw Me Tomorrow, created during a residency at USF in Bergen, Norway, explores visual improvisation through the use of Nintendo’s Wii Remote Controller in combination with a laptop’s built-in iSight webcam—a setup Sachiko refers to as WiiSight. This system uses no prerecorded material; instead, all visuals are captured live and undergo real-time manipulation via Max/Jitter. The work premiered at Fylkingen, Stockholm, in 2010.

Virtual Photography in Second Life

Several series of virtual photography taken in Second Life.

process (video)

process consists of five video clips, each featuring a dancer and his/her movements.  It discloses the behind-the-scenes creative process and blurs the line between the public and the private. Revealing what is normally hidden, process creates an in-between space where the exposed reenacts with the concealed. 

Experimentation (mixed reality audio-visual performance in Second Life, using Kinect)

The project completed during a residency at Humlab, Umeå University, Sweden, was documented as Machinima. This mixed reality audiovisual performance utilised Kinect to synchronise sound and movements between a virtual environment avatar and the real-life user/performer. More info

Memory Loop (video)

Memory Loop is a collaborative project between Jair Rohm Parker Wells (music) and Sachiko Hayashi (image), comprising three independent video works: Jair Rohm, Sachiko, and Magnus. Each piece explores the ineffable emotions tied to the passage of time, as captured in family photographs. Through these images, photography becomes a medium for weaving the threads of time, connecting the past to the present in a continuous loop of memory and reflection.

Still Untitled (gesture-controlled interactive audio-visual performance)

Still Untitled is an interactive audiovisual performance utilising Leap Motion to translate the performer’s arm movements into real-time control of visual and auditory elements. To the generative moving picture, the laptop itself serves as a resonant box, amplifying and shaping the sound, creating a cohesive interplay between gesture, sound, and visuals.

Lipstick to Live Music (gesture-cotrolled live cinema)

Gesture-controlled moving picture via Leap Motion and laptop built-in webcam. To the live electric music of Magnus Alexandersson – guitar, electronics, Girilal Baars – voice, theremin, electronics, Jonas Broberg – electronics, Lars Bröndum – electronics, theremin

Hard Candy (gesture-controlled interactive audio-visual performance)

Hard Candy is an interactive audiovisual performance that uses the Myo armband as its interface. The armband leverages electromyography (EMG) sensors to detect electrical signals produced by muscle contractions in the forearm. During the performance, the Myo armband translates the performer’s muscle activity into precise control inputs, enabling real-time manipulation of both visual and auditory elements.

GenAI Image and Video Series

Various Gen AI image and video series based on the imageries generated with Midjourney. From cat woman to ghostly imageries from the past.

Forming Sa-AI-Rohm with Jair-Rohm Parker Wells

Echoes Unseen (gen AI video trilogy)

GenAI videos—Collage Me, Women with A Camera, and In My Mind’s Eye— together form the trilogy Echoes Unseen.
The trilogy is a journey through time, memory, and imagination, told with the lens of artificial intelligence. Each piece in the trilogy serves as a chapter in an evolving narrative that converges the past with the present and ventures into the limitless realms of the human psyche. Collaboration with Nina Sobell on sound for In My Mind’s Eye. Selected as the Best Short Film 10-20 min. at LuminaFlickss International Short Film Fest.

Mara Series (generative AI video series)

The GenAI video series, Mara, based on images generated with Midjourney, explores the representation of women as profound and enigmatic forces of both creativity and darkness. The work continues themes of the dual nature of female power, first examined over 25 years ago during postgraduate studies in the UK and Stockholm, through the CD-ROM projects Nyx and The Norns, respectively.
