ocated in the heart of Japan’s snow country, Echigo-Tsumari is home to mountainous terrain and a satoyama which is an agricultural expanse, where traditional ways of farming are still being practised. While rich in nature, the region has slowly been suffering from an ageing and decreasing population – a serious phenomenon that has seen many of the young, rural people moving to the big cities for work or education opportunities. This has left the elderly (65+ years) accounting for 37% of the community, while the average level in Japan is 27.7%.
In 2000, Fram Kitagawa founded the Echigo-Tsumari Triennale as a means of restoring the cultural energy that had become lost in the region. Spanning more than 760km², the Echigo-Tsumari Art Field hosts approximately 160 artworks, across 200 villages. The art installations are realised in collaboration between internationally-renowned artists and locals and are dispersed throughout the area’s fields, forests, empty houses, schools and other abandoned spaces. Works from past editions have remained intact, forming an integral part of the local environment, even after the triennale has concluded, as a means of culturally enriching the area. In a community that has lost its dynamism, and has become isolated, the Echigo-Tsumari Triennale seeks to reconnect people with the place, as well as with one another. While viewing artworks, visitors must physically traverse the terraced rice fields, or walk through the beech wood forest. Thus, it presents a new model for how humans can relate to nature, cultivating the land with art and cultural works as an ongoing process of urban reactivation. In turn, it also encourages cooperation between different generations and neighbouring regions.
As part of the 2018 programme, MAD Architects was invited to revitalise the Kiyotsu Gorge Tunnel – a historic, 750m passageway that cuts through distinctive rock formations, offering panoramic views over one of Japan’s three great chasms.
Drawing on the ‘five elements’ of nature (wood, earth, metal, fire and water), MAD’s scheme transforms points along the historic tunnel through the realisation of several architectural spaces and artistic atmospheres. The designs rethink the relationship between humans and nature and seek to reconnect locals and visitors alike with the majestic beauty of the land.
Upon the approach to the tunnel, a small wooden ‘hut’ has been erected that serves as the cafe and souvenir shop (with locally-made crafts) on the ground floor. Inside the pitched cedar roof on the upper level is a hot spring foot spa. A circular aperture – the ‘Periscope’ – in the ceiling opens up towards the roof. Encircled by mirrored lenses that reflect the nature of the surrounding site inwards, the subtle intervention gives visitors the opportunity to enjoy the natural scenery outdoors, while they have a foot bath and relax within the warmth of the wooden interior.
Expression of Color (earth)
The entrance to the tunnel has been restored to its former glory and leads the way to the newly-renovated passage. Illuminated initially through natural means, it has been outfitted with a series of different coloured lights which define each lookout point along the tunnel. Captured as ‘the expression’ of the space, their vibrancy, in combination with mysterious music, sets a subtle but dynamic ambience that sparks a certain curiosity of the unknown for those who are wandering through.
Invisible Bubble (metal)
The first of the lookout point renovations is the Invisible Bubble. As if landing from another world, the capsule-like structure gently mirrors the silhouette of the tunnel itself, while reflecting its surroundings. Functioning as a toilet, the wall which faces towards the gorge is transparent. This exterior window is covered in a metallic film that only allows one-way views from the inside out, playing with the notion of public and private. Providing a quiet escape; a place of solitude, it is an intimate space that finds itself in an openly public setting.
It puts into question how people react when they think that no one is watching – an ideal corner of contemplation.
The Drop (fire)
‘Dewdrops’ are scattered along the curvature of the second lookout point. The drop is a series of reflective openings that are like windows of uncertainty. While they project a reality by mirroring the natural environment, they also appear surreal, like molecules of water, they are suspended from the ceiling and walls, frozen in time. As one looks into these convex mirrors, backlit by fiery, red light, they experience an alternative connection with nature – one that is at once mysterious and warm.
Light Cave (water)
The culmination of the restoration is expressed in the form of the Light Cave. Semi-polished stainless steel lines the tunnel, drawing the distinct rock formations, lush greenery and turquoise water of the treasured terrain, into the enclosed space. A shallow pool of water gently ripples in the breeze of the wind. In turn, the images of the gorge reflected from the cave cast themselves onto the water – an infinite illusion of nature. The essence of the Light Cave brings both a lightness and stillness into the once dark, dewy tunnel, evoking a feeling of everlasting solitude.
MAD’s Tunnel of Light is an artistic transformation that demonstrates how art and nature can come together to reinvigorate a community. Each one of the installations forms a poetic space where visitors can transcend the role of observer, and become an active participant – allowing individuals to place themselves in nature in unexpected ways.
