"teamLab: Yoro Valley," a night outdoor art exhibition, is now open at Yoro Valley in Chiba — a hot spring resort area on the Boso Peninsula. The exhibition runs from April 17 (Friday) to May 24 (Sunday), 2026. A series of artworks transforms the gorge, carved out over vast stretches of time, into an art space that shifts in response to the people present in it today.
Tickets are available at the official website:

Concept
Yoro Valley becomes an art space that changes with the presence of people living in the present moment, reconnecting visitors with a sense of long spans of time and their continuity.
Yoro Valley was carved by the Yoro River over countless ages. Located upstream of the Chibaian (Chiba Age) geomagnetic reversal stratum — the world's clearest geological record of the Earth's north and south poles switching — this gorge is also home to the Kurotaki Unconformity, a rock face designated as one of Japan's 100 Geological Sites. The ancient forest, the river ceaselessly eroding the earth, the canyon walls and their exposed strata all carry immense spans of time within them.
teamLab pursues the concept of "Digitized Nature," in which nature itself becomes art. The goal of the exhibition is to take these vast time-holding forms and transform them through the presence of people living today — creating a place where visitors can feel the continuity between deep time and the present, and recognize that their own existence rests upon the long, unbroken chain of life.
Artworks
Life and Death in the Continuity of an Immense Today
The vast geological canyon at Yoro Valley — an immense "Deep-time Sculpted Existence" formed over millions of years as flowing water eroded the strata and exposed the Earth's memory — carries within it the weight of deep time, embedded in its shape, texture, and presence.
In this overwhelming space, flowers are born and die repeatedly, shifting forever as the time of life flows through.
When you become part of this existence that holds vast time within it, you may notice that the accumulated immensity of time is continuous with the present. Walking between these two streams of time, one can feel throughout the body that one's own existence rests upon an endless, boundaryless continuity of deep time.
Waterfall Haunting the Valley Forest
Resonating Yoro Valley and Forest
The trees glow with light. Each tree's light is autonomous, flickering as if breathing slowly. When people pass nearby, or when light propagates from the neighboring artwork "Forest of Resonating Life — Independent and Resonating," the trees change color and emit a tone unique to that color. The light then spreads to surrounding trees one after another, resonating with sound as it continues.
When light surges from deep within the forest, it signals that people are further inside. Visitors become more conscious than usual of the presence of others sharing the same space.
Strata of Traces of the Valley
Darkness lies in the foreground, and light exists in the depths. Material boundaries dissolve, substance and perception become ambiguous, and ethereal forms emerge.
Pillar of Constant Flux
Objects created by humans — concrete and the like — are stable structures in themselves, like stones. A whirlpool, however, sustains its structure through water continuously flowing from outside to inside and back; its order is maintained by the ceaseless movement of water. Life, too, is sustained by the flow of energy and matter through food, passing continuously from outside to inside and back. This work has no structure of its own — structure is born within flow, supple and soft like life itself. Flow gives rise to order from chaos.
The work is strongly influenced by wind, rain, humidity, and other environmental conditions, causing the pillar's movement and height to change significantly.
Non-Dual Mass of Life and Death
Death and life may appear to be two separate things, but they are in fact one and inseparable. Over vast stretches of time, life has sustained death and death has sustained life — an ephemeral mass within the eternal continuity of life.
Eternal Prayers in the Rock Cavern
Deep in a rocky cavern, calligraphy is written in an endless stream. A monk reads each character aloud as it is inscribed. The voice of each character echoes from its position within the calligraphy, and hundreds of thousands of chanting voices resound in continuous succession.
Crystal of Accumulated Time
Forest of Resonating Life — Independent and Resonating
Densely standing ovoids (egg-shaped forms) of light, each autonomous. When an ovoid is displaced by a person or blown by the wind and falls, it rises again, changing its color and emitting a tone unique to that color. The surrounding ovoids respond in turn, changing to the same color and resonating with sound in a continuous chain.
When the wind is still and people are inactive, the ovoids begin to flicker slowly.
Captured Continuous Life
A photograph of the forest flattens and frames it through the lens. This work cuts out the forest as it is, using light.
The exhibition is part of Chiba Prefecture's ongoing initiatives to develop the Yoro Valley Onsen area as an appealing tourism destination, encompassing regional branding, tourism content development, and improvements to visitor convenience.
