TRACE is a collection of 11 unreleased tracks produced by Yutaka Hirose during the Sound Process Design sessions, right after the release of his classic Soundscape series album Nova. Sound Process Design was Satoshi Ashikawa's label, home of his Wave Notation trilogy (Hiroshi Yoshimura’s Music For Nine Postcards, Satsuki Shibano's Erik Satie 1866-1925 and Satoshi Ashikawa's Still Way). Following Wave Notation, Sound Process Design worked with museums, cafes and bars to create site-specific soundscapes, starting with the sound design of the Kushiro Museum. Yutaka Hirose was called to work on sound for these spaces.
Rather than simply providing pre-recorded compositions, Hirose sought to create a "sound scenery". To achieve this, he participated in the conception of the space and paid particular attention to the accidental combination of sounds by placing the speakers and using a multi-sound source, and following the concept of "sculpturing time through sound".
The composer explains: "sculpturing time through sound means that the time, the space itself, the sound played in it, and the audience all become one sculpture. It is close to the idea of a Japanese tea ceremony where you use all of your 5 (or 6) senses to taste the tea."
TRACE: Sound Design Works 1986-1989 is divided into two parts. "Reflection" is based on an ambient soundscape. It narrates "a sleep that starts with the sound of water droplets at dawn and slowly disappears into darkness" and feels like a natural and soothing progression of Nova. It was played at entrances of spaces, at events, in cafes and bars. "Voice from Past Technology" expresses the dream world born out of that sleep and is based on what Yukata Hirose calls hardcore ambient, environmental music with a noise approach. It was played in museums and science centers.
All in all, TRACE is a crucial addition to every Japanese environmental music fan’s collection, alongside Midori Takada’s Through The Looking Glass, Hiroshi Yoshimura’s Green, Satoshi Ishikawa’s Still Way, Motohiko Hamase’s Notes of Forestry, Inoyamaland’s Danzindan-Pojidon, and Yutaka Hirose’s very own Nova.

Essential Japanese Ambient / Electronic / Minimalism from MOTOHIKO HAMASE
Co-produced by YOSHIO OJIMA / Featuring SATSUKI SHIBANO
Originally Released in 1988 via NEWSIC / WACOAL ART CENTER
Official Reissue Overseen by the Artist / With Liner Notes
Reissued in Conjunction with Hamase’s Anecdote and Technodrome albums
From the ESPLANADE_SERIES
An Archival Focus on Yoshio Ojima, Satsuki Shibano, and Motohiko Hamase
WRWTFWW Records is excited to announce the official reissue of Motohiko Hamase’s remarkable ambient/environmental/minimalism project #Notes of Forestry, available for the first time since 1988. The album is sourced from original masters and available on vinyl and CD with liner notes from the artist. This marks the third release from the ESPLANADE SERIES which focuses on the works of Yoshio Ojima, Motohiko Hamase and Satsuki Shibano.
One of the most fascinating and peculiar works from the golden era of Japanese ambient, #Notes of Forestry was initially released in 1988 by Newsic, the cult label started by Tokyo’s Wacoal Art Center (also known as Spiral), home, notably, of Yoshio Ojima who co-produced the album. Conceived by Jazz bassist turned experimentalist Motohiko Hamase, the magnum opus offers an enchanting mix of free-form pastoral electronics, otherworldly percussions by Yasunori Yamaguchi, and delightfully allusive piano played by none other than Satsuki Shibano (Sound Process’ Wave Notation 3).
Vibrant, sometimes eerie, and absolutely captivating, #Forestry captures Hamase’s quest for musical freedom, he explains:
"Inside the body of a musician, music is always transcendentally resonating. More than language, music reigns. When creating music overlaps with the moment my body performs, I strive to be as close as possible to the feeling of musical freedom. I feel that this notion lies at
the foundation of this album".
Musical freedom, here, provides an essential escape, extending the path uncovered by pivotal releases such as Midori Takada’s Through The Looking Glass, Satoshi Ashikawa’s Still Way, and Yutaka Hirose’s Nova.


Masahiro Sugaya began his career in the 1980s, working alongside the environmental music scene of that era while also making a significant impact in stage music through his involvement with Pappa TARAHUMARA.
Over the past 20 years, Sugaya has shifted from traditional composition using instrumental music to creating works for 8-channel multi-speaker systems, incorporating environmental sounds and field recordings. His latest album continues this evolution, featuring collages of environmental sounds within individual tracks. The album is structured to balance past and new works, creating a collage-like representation of Sugaya’s diverse creative output.
"しるしまみれ / Overflowing Signs" offers an experience that navigates freely between Sugaya’s environmental music approach and his practices in field recording and musique concrète, presenting a sequence of sounds that defies easy categorization or symbolism. Additionally, this album marks Sugaya’s first stereo full album release in nearly 20 years.








Kindred spirits Passepartout Duo and Inoyama Land embody the essence of play – charting a new chapter and reinvigorating the environmental music and electronic landscape.
Passepartout Duo is formed of Nicoletta Favari (IT) and Christopher Salvito (IT/US), who since 2015 have been on a continuous journey travelling the world’s corners, engaged in a creative process they term “slow music”. Having been guests of many notable artist residencies and with live performances in cultural spaces and institutions, their evocative music escapes categorisation. With no fixed abode their musical pilgrimage brought them to Japan first in 2019, which prompted a deep connection to Kankyō Ongaku ‘environmental music’, a genre in which Inoyama Land is often associated with, soundtracking the duo’s first immersive experience. In 2023 the duo revisited Japan and set out to reconnect in particular with the music of Inoyama Land, performed by Makoto Inoue and Yasushi Yamashita. The highly revered album ‘Danzindan-Pojidon’ (1983) produced by Haruomi Hosono amongst other well publicized and acclaimed reissues (Light in The Attic Records’ Grammy-nominated compilation ‘Kankyō Ongaku’), produced a global resurgence and admiration of the environmental music movement. Nicoletta took the lead to seek out Inoyama Land and in making contact successfully their intrigue and eagerness to meet was warmly reciprocated, and the group scheduled to meet in the form of a spontaneous improvisation session.
“We’re deeply concerned with what it means to be a duo, and what it means for people to connect through music.”
'Radio Yugawara' was recorded in 2023 in Makoto Inoue’s hometown of Yugawara where his family runs a kindergarten, whose space has doubled as a Sunday recording studio. Upon arriving a circle of four tables was set up in the school’s auditorium - the tables were carefully populated with children’s instruments: a full set of handbells, a glockenspiel, a xylophone, recorders, melodicas, and harmonicas. Surrounding the tables were racks hanging all sorts of bells and wind chimes and within this environment each performer set up their own electronic instruments. Dialling into each other, a simple set of playground ‘game rules’ was devised where time was divided into three separate sessions (1) ‘only electronic instruments’, ‘only acoustic’, and ‘a mix of both’, (2) ‘revolving duets’ each taking turns to play through a cycle of ‘four duos’ and (3) ‘anything permitted’, accumulating to more than three hours of material which was then carefully distilled into succinct tracks. The alluring album opener ‘Strange Clouds’ oscillates into view, setting a lush scenery built from a bed of synthesisers and the first glimpse of the chromaplane, the hand-built analogue instrument designed by Passepartout Duo, featuring a touchless interface and endless organic sounds that underpin the album’s 11-track inlets. Percussive pulses act as the heartbeat to ‘Abstract Pets’ before earthy sub-swells open the pathway to glistening glockenspiels and wind chimes. The atmosphere shapeshifts with ‘Simoom’ and ‘Tangerine Fields’ with swirling synth lines and subliminal beats resembling changes in weather patterns. At the centre points the idyllic ‘Observatory’ and ‘Mosaic’ could illuminate the deepest oceans before the hypnotic, arpeggiating synth lines in the otherworldly ‘Xiloteca’ propel the album towards ‘Solivago’, with its gentle lullaby of playful ambience. The reflective closer ‘Axolotl Dreams’ resolves their somewhat chance meeting with elegant pastoral chord strokes and uplifting synth swells, sending final signals upwards into the ether.
'Radio Yugawara' is a unique one-off transmission from a specific place and point in time, unlikely to ever occur again. The respective duo’s approach can really be described as “tuning in”, a tuning into each other, to themselves, and to the surrounding nature of Yugawara. Like waves that travel off-world, sounds travel through the universe and can be lost forever if we don’t seek them out. In finding a harmonic affinity within their instruments and a spiritual kinship in their interwoven performance, Radio Yugawara at its core is an interpretation of feeling, of close human interaction and the true essence of discovery.
“The album is both a transmission from a location, but also a tuning into the surroundings and to each other. Music in this kind of ephemeral moment is much less about active creation and more about discovering something which is already there in the air.”






Barely known outside of his home country during his lifetime, the late Japanese ambient music pioneer Hiroshi Yoshimura has seen his global stature rise steadily in the past few years. The 2017 reissue of his lauded debut, Music For Nine Post Cards, along with a slow building cult internet following has helped ignite a renaissance in his acclaimed body of work, much of which has never been released outside of Japan. Known for his sound design and environmental music, Yoshimura worked on a number of commissions following the 1982 release of Music For Nine Post Cards, including works for museums, galleries, public spaces, TV shows, video art, fashion shows, and even a cosmetics company. Originally released in 1986, GREEN is one of Hiroshi Yoshimura’s most well-loved recordings and a favorite of the artist himself. Recorded over the winter of 1985-86 at Yoshimura’s home studio, the compositions unfold at an unhurried pace, a stark contrast to the busy city life of Tokyo. As Yoshimura explained in the original liner notes, the album title in the context of this body of work is not meant to be seen as a color, but is rather used to convey “the comfortable scenery of the natural cycle known as GREEN”—which perfectly encapsulates the soothing and warm sounds contained on the album, although it was created utilizing Yamaha FM synthesizers, known for their crisp digital tones. This edition marks the first reissue of the highly sought-after and impossible to find album. It features the original mix preferred by Yoshimura himself, previously available only on the initial Japanese vinyl release (a limited edition remixed version of the album, with added sound effects, was released on CD in the US). Additionally, this release is the first in our ongoing series, WATER COPY, focusing on the works of Hiroshi Yoshimura.

Limited Clear Vinyl. Despite his status as a key figure in the history of Japanese ambient music, Hiroshi Yoshimura remains tragically under-known outside of his home country. Empire of Signs – a new imprint co-helmed by Maxwell August Croy, Spencer Doran and distributed by Light In The Attic – is proud to reissue Yoshimura’s debut Music for Nine Post Cards for the first time outside Japan in collaboration with Hiroshi’s widow Yoko Yoshimura, with more reissues of Hiroshi’s works to follow in the future.
Working initially as a conceptual artist, the musical side of Yoshimura’s artistic practice came to prominence in the post-Fluxus scene of late 1970s Tokyo alongside Akio Suzuki and Takehisa Kosugi, taking many subsequent turns within Japan’s bubble economy afterward. His sound works took on many forms – commissioned fashion runway scores, soundtracking perfume, soundscapes for pre-fab houses, train station sound design – all existing not as side work but as logical extensions of his philosophy of sound. His work strived for serenity as an ideal, and this approach can be felt strongly on Music for Nine Post Cards.
Home recorded on a minimal setup of keyboard and Fender Rhodes, Music for Nine Post Cards was Yoshimura’s first concrete collection of music, initially a demo recording given to the Hara Museum of Contemporary Art to be played within the building’s architecture. This was not background music in the prior Japanese “BGM” sense of the word, but “environmental music”, the literal translation of the Japanese term kankyō ongaku [環境音楽] given to Brian Eno’s “ambient” music when it arrived in late 70’s Japan. Yoshimura, along with his musical co-traveler Satoshi Ashikawa, searched for a new dialog between sound and space: music not as an external absolute, but as something that interlocks with a physical environment and shifts the listener’s experience within it. Erik Satie’s furniture music, R. Murray Schafer’s concept of the soundscape and Eno’s ambience all greatly informed their work, but the specific form of tranquil stasis presented on releases like Nine Post Cards is still difficult to place within a specific tradition, remaining elusive and idiosyncratic despite the economy of its construction. This record offers the perfect introduction to Hiroshi’s unique and beautiful worldview: it’s one that can be listened to – and lived in – endlessly.



The second LP by Tokyo ambient conceptualists UNKNOWN ME began as a commission for historic Japanese cosmetic conglomerate Shiseido, conjuring audio approximations of seasons and scents, but soon flowered into its own refracted environment: Bitokagaku. Translated as “beauty and science,” the album is the foursome’s first composed solely with software, reflecting the collection’s utopian, laboratorial muse.
From levitational electronica (“A Rainbow in Meditative Air”) and vaporous downtempo (“Dancing Leaves”) to planetarium reverie (“Kitsune No Yomeiri”) and A.I. IDM (“Retreat Beats”), the music moves like weather patterns in a bio-dome: dazzling, microcosmic, and delicately calibrated. Percolating synths crossfade with field recordings from Shiseido’s research division; the sound of streams and distant birds blur into a processed haze; clinical voices read lists of precious stones. It’s a vision of new age as soft robotics, of serenity streamlined by sentient systems.
UM’s team of engineers (Yakenohara, P-RUFF, H. Takahashi, and Osawa Yudai) cite an eclectic swath of inspirations behind Bitokagaku – molecules, stars, Kenji Miyazawa, Akira Kurosawa, even “the sparkle of rainbows” – but their guiding artistic principle is as ancient as it is eternal: “beauty.”

"Night Rhythms proudly presents a first-time vinyl edition of Toshimi Mikami’s elusive gem of 90’s ambient “気舞 - Quimai” (“Chi Dance”). Released on CD in 1996 and again in 2008, this double LP version marks the first time the album will be readily available outside of Japan. Mikami states: “I made this album mainly as background music for Qi Gong, Tai Chi, yoga, etc., but I also want people to use it for various other kinds of relaxation.” The music reflects the practice of these deliberate, meditative disciplines with spacious motifs carried along by a steady rhythmic current. In his liner notes for the original CD edition, which are reprinted here, Mikami’s one-time bandmate Harumi Hosono writes of the evolution of the ambient/“organic” strain in 20th century music that “eyes, ears, and hearts opened like never before may now extend beyond notions to the specks of the natural world.” Ambient music isn’t music stripped of meaning, but rather its meaning finds form in our connection to the most basic elements of our environment, as distinguished from what Hosono calls the “endlessly exhausted economic principles” of modern pop music.
“Quimai” exists at the intersection of ambient, new age, and classic minimalism, with a gentle synthetic palette of global instrumentation layered and braided into fully orchestrated compositions. Relaxing though it may be, it’s a very focused sort of relaxation that encourages active listening rather than the blissful “tuning out” that some ambient music can inspire. Opening track “十六夜の月 Izayoi No Tsuki” immediately calls to mind Steve Reich’s work with its insistent 6/4 pulse and prominent woodwinds and percussion. “玉響 Ai Ai” continues on a similar footing, with shards of sunlight glinting off an otherwise untroubled and tireless stream. The enchanting marimba ostinato of “玉響 Tamayura” has a subaquatic quality, as if the listener is now witnessing the events on the water’s surface from below. Mikami follows it with “早乙女 Saotome,” a carefree piece that sheds the vestiges of tension present in the preceding tracks and features a playfully cascading gamelan figure. All underlying rhythmic churn falls away with album-closer “天の小道 Ama No Komichi,” an airy piece that maintains a structure similar to its sibling works while coming closest to the new age tradition, breathing freely without ever standing still. One can imagine Mikami or other practitioners enacting the final movements of their daily exercise — body tired but limber, mind reset.
This gatefold double LP edition is mastered from the original source by Travis Nordahl with lacquers cut at Palomino Records (USA). Track 3 “玉響 Tamayura” has been slightly abridged to fit the constraints of the format. Artistic elements of both CD editions have been combined by Joe Bastardo with additional nature photography courtesy of Night Rhythms Recordings owner Greg Holly. Liner notes by Toshimi Mikami and Harumi Hosono."
