YAKUSHIMA

Known as the “Alps on the Ocean”, Yakushima is a UNESCO World Heritage island off the southern coast of Kyushu, rising from subtropical lowlands to snow-capped peaks. Its ancient cedar forests, moss-covered rocks and white-sand coastline create a landscape that feels far beyond the human scale. Some of its yakusugi cedars are more than a thousand years old, while its unspoilt terrain and rapidly changing weather reinforce the sense that people remain guests of nature.

When we first encountered the site, its beauty was inseparable from its demanding conditions. An existing pond, exposed rock, intense rainfall, typhoon winds and sudden shifts in visibility had to be understood as parts of one living system. We began by listening to the land - studying its contours, water and vegetation before defining form. Rather than imposing a predetermined style, we allowed these conditions to establish the project’s spatial logic. Conceived for NOT A HOTEL, a Japanese hospitality concept that combines architect-designed holiday homes with the restorative experience of a private retreat, the house emerges as a quiet embodiment of Ma (間) - the meaningful interval between elements.

The house unfolds as a constellation of individual volumes connected by courtyards, gardens and transitional spaces. These active voids form the true structure of the project, shaping movement, framing nature and creating a measured rhythm between intimacy and openness. Here, the void is as important as the material form surrounding it, bringing the individual elements into a harmonious whole. Moving through the house becomes a gradual unfolding of relationships with light, water, nature and sky.

At the centre of the house, a courtyard garden forms the contemplative heart of the residence. Composed of water, stone and bonsai trees, it introduces a point of stillness into daily life. Architecture and landscape create the quiet needed to perceive nature’s smallest events: a ripple moving across water, leaves stirred by the wind or light shifting across stone. Yakushima’s frequent rainfall is also integrated into the design through rain-fed reflecting basins, where falling water creates gentle ripples and a meditative soundscape.

Responding to Yakushima’s steep terrain and intense rainfall, the house is raised on piles by up to one metre, allowing water to flow naturally beneath it and minimising changes to the landscape. The roofs translate two further references into architecture: origami and falling leaves. Like folded paper, each roof plane bends, breaks and slips beneath the next, creating a continuous composition of overlapping surfaces. Seen together, the individual roofs resemble leaves falling and settling across the forest floor. Origami provides the logic of folding and intersection; leaves introduce movement, irregularity and a direct connection to Yakushima’s forest. Through these transformations, culture and craft become defining principles of the house's appearance.

Rather than reproducing the appearance of traditional Japanese architecture, the project translates its deeper principles - restraint, attentiveness and the balance between form and void - into a contemporary way of living. The architecture does not compete with the intensity of Yakushima; it creates a measured place from which to experience it, turning each stay into an opportunity for stillness, reflection and renewal.
