GALLERY MoMo Ryogoku is pleased to present "Listening to the Voices of Sediment", a solo exhibition by Kumiko Muroi, running from May 16 to June 13, 2026.
Throughout her career, Muroi has confronted fundamental themes of life and death, as well as the threshold between "Higan" (the other shore) and "Shigan" (this shore), rooted in personal experiences of loss, disaster, and illness. Her time living in the mountainous regions of Tohoku sparked a profound interest in the mountain worship of Yamagata. Subsequent physical journeys to sacred sites across Japan—including the Oshira-sama traditions of Tono, the spiritual grounds of Osorezan, and the Utaki of Okinawa—have led her to an even deeper and more resonant perspective on mortality.
Muroi’s work focuses on the "hazama" (in-between) opposite elements: light and darkness, memory and oblivion, joy and emptiness, and the boundary between "this side and the other side." Using a palette primarily of purples and grays with fluid, sweeping brushstrokes, she has established a unique style that defies simple classification as either figurative or abstract. Her canvases manifest contradictions and give form to the formless.
The exhibition title’s keyword, "Ori" (Sediment), refers to the matter that settles at the bottom of water, or the accumulation of forgotten emotions and souls. For Muroi, the annual rings of ancient trees, the layered cloths of Oshira-sama deities, and the layers of paint on her canvas are all equally "sediments of time."
In a departure from her previous darker tones, this exhibition features large-scale oil paintings with vibrant colors reminiscent of the open sky. Alongside these, the show will include monotypes and drawings—latest works born from a dialogue with figurative forms and settled memories—offering a glimpse into a new stage of Muroi’s artistic expression.
As Muroi states, she seeks to "reflect the boundary itself, rather than choosing between figuration and abstraction." We invite you to experience the "voice of sediment" that rises from the interstices of her work, awakening a sense of the "other side" that we so often lose sight of in our daily lives.

Artist Statement
What lies between the other shore (Higan) and this shore (Shigan)?
I travel. To the mountain faiths of Yamagata; to the Oshira-sama of Tono in Iwate; to Osorezan in Aomori; to the sacred realms of Izumo in Shimane; to the Utaki of Okinawa; and to the Sokushinbutsu (self-mummified Buddhas). I visit these sites of faith to immerse myself in the time and atmosphere that breathe there. These journeys are neither tourism nor academic research; they are an act of layering my own senses upon the accumulation of memory known as folklore.
In the folk beliefs of this country, there is a fundamental will to treat the boundary between the dead and the otherworld with great care. In mountain worship, exemplified by the Three Mountains of Dewa, the mountains themselves are seen as dwellings for the souls of the departed. Practitioners (ascetics) have long experienced the threshold between life and death through the physical act of walking steep, rugged paths. The Oshira-sama of Tono are enshrined in layers of cloth—a form that is the very embodiment of memory piling up in strata. The Itako of Osorezan call the dead back to this shore through the medium of words. In the sacred lands of Izumo, myriad deities gather across time and space. In the Utaki of Okinawa, ancestral spirits reside within the forests, where women known as Noro or Yuta mediate between the spiritual world and the present. I have also gone to meet the Sokushinbutsu several times. Their bodies, remaining on this shore while consciously embracing death, are the crystallization of the boundary between the two shores, rendered into flesh. Every faith arises from a sense of keeping the departed close to our daily lives rather than distancing them.
When I walked through Osorezan in Aomori, the searing heat of the ground and the incredibly clear blue sky spreading overhead rushed toward me at once. It felt as if my own body stood as a single boundary between hell and heaven. When stepping into places where few people visit, one is sometimes enveloped in a sensation of something that had been submerged at the bottom of the water gently floating to the surface. "Ori" (Sediment) refers to that which settles at the bottom, or the stagnation itself. It is the invisible accumulation hidden in the depths of clear water—sometimes a deposit of forgotten memories, emotions, or souls. The "voice" emitted from there is an unspeakable whisper, an afterglow of the past, a fundamental resonance of existence.
I have also go around visiting giant trees. Trees that carve centuries, sometimes over a millennium, into their trunks—connecting to the depths of the earth with their roots and stretching toward the heavens with their branches. Standing before them, the smallness of my own body and the sensation of certainly standing on "this shore" rush over me simultaneously. The annual rings of a giant tree, the layered cloths of Oshira-sama, the layers of paint—all are "sediment." Time settles, atmosphere accumulates, and eventually, they take the shape of a single voice.
And now, I live in Ome. Okuchi-no-Magami, enshrined at Musashi Mitake Shrine—this local faith that reveres the wolf as a divine messenger—resonates quietly with the memories of my distant travels. Within my daily life, the "other shore" is already woven in.
I used to practice calligraphy and archery. In a single stroke of the brush, there is a moment when the body moves before thought. The same is true of the instant an arrow is released in archery—it is only when you stop "aiming" that you finally hit the target. Standing before a canvas, I recall that sensation. Hands move, paint layers, disappears, and remains. Just as Sesshu allowed the spiritual aura of the mountains to reside within the yohaku (blank space), I too attempt to place the "other side" within the unpainted areas. Layers of time and physicality pile up on the surface, eventually forming a certain presence.
Countless stars scattered across the night sky hold no meaning in themselves. Yet, since ancient times, humans have drawn lines between points, finding myths and forms of prayer. Constellations are the fundamental human impulse to visualize the invisible. My act of facing the canvas is similar—drawing faint lines between countless traces. The screen, swaying between color and matter, is neither figurative nor abstract, but seeks to reflect the boundary itself. The other shore is always within the margins of this shore. And we are always standing on this shore, drawing lines toward the invisible.

作品解説

Voices of the Sediment Ⅰ
2025 oil on canvas 194.0 x 162.0 cm
The elements have not yet settled into sediment. Blue and purple tones swirl together, indicating an upward movement. No clear boundaries have been established—capturing the state of a voice before it forms into distinct sound, or a tremor prior to submersion.

Voices of the Sediment Ⅱ
2026 oil on canvas 194.0 x 162.0 cm
Those that failed to cross over sink to the bottom of the boundary. Along the Koshu Kaido highway, the round stones (maruishi) of Yamanashi Prefecture have lost their sharp edges and become spherical over a long period of time. This shape is eventually acquired by the uncrossed elements accumulating at the bottom—it represents a form of completion, rather than a loss. The voices originate from this very bottom.

Starlight
2024 oil on canvas 116.7 x 91.0 cm
Historically, the souls of the deceased have been conceptualized as turning into stars. Humans have connected these distant points with invisible lines to identify mythical figures. Constellations represent the oldest human impulse to visualize the unseen.
Floating Sway
2026 oil on canvas 116.7 x 91.0 cm
ubmerged elements do not remain static. They driven to rise yet are unable to fully surface—this suspended animation reflects the very respiration of souls drifting between life and death.

Shikii -Liminality-
2026 oil on canvas 23.3 x 16.0 cm
A single line on the floor separates the sacred space from the secular world. Stepping over it causes a transition. Choosing not to step over it keeps one in place. However, remaining indefinitely on the threshold is not permitted.

Migiwa -Waterside-
2026 oil on canvas 27.3 x 22.0 cm
The edge where water and land meet—the final line where those who failed to cross over wet their feet. In the folklore of riverbank and coastal communities, the waterside repeatedly appears as a space where the living and the deceased exchange words.

Tasokare -Twilight-
2026 Colored pencils and acrylics on paper 23.5 x 17.0 cm
The transition between day and night—the hour of dusk when individual faces become indistinguishable. In folklore, this is considered a critical period when the boundary grows thinnest, a moment when this world and the afterlife overlap like a single breath.

Yamagiwa -Mountain Rim-
2026 Colored pencils and acrylics on paper 17.0 x 14.0 cm
In mountain worship, mountains have traditionally been viewed as the dwelling place for the souls of the deceased. The ridgeline where the mountain meets the sky represents the edge of this world—a single boundary line quietly drawn between heaven and earth.

Call of the Mountain
2026 Monotype 24.5 x 33.5 cm
The concept of the mountain calling to humans is widely prevalent in Japanese folklore. The source of the voice remains invisible. However, the moment one listens closely, their feet have already stepped across the boundary.

Lines—As Boundaries
In folklore, the boundary separating this world and the afterlife has been conceptualized as a "pure line with no surface area." A river's surface, a gate frame, or a sacred straw rope (shimenawa)—each partitions space into internal and external realms while belonging to neither. As Kunio Yanagita pointed out, Dosojin (roadside deities) and Sae-no-kami (border deities) are enshrined precisely "on the line," such as village borders, mountain passes, and crossroads. A boundary is not a physical place; it is the transition itself. As Arnold van Gennep’s theory of the rites of passage demonstrates, the exact moment of crossing the line is the core of transformation, and the control of this permeability separates the living from the deceased.

Circles (Spheres)—The Spiritual Power of a Completed Form
In the round stone (maruishi) worship concentrated in Yamanashi Prefecture, natural round stones placed along the Koshu Kaido highway and at village borders have been enshrined as sacred objects (shintai). Kunio Yanagita pointed out that spiritual power resides not in the stone itself, but rather in its "round" morphology. A circle, having neither a beginning nor an end, symbolizes the cycle of death and rebirth; because it lacks sharp edges, it can accommodate spiritual forces from all directions. The reason the round form is linked to the origin of life and the primordial universe across various world cultures is that it simultaneously encompasses both the beginning and the end.
