The site for this project is a prime location in Oku-Yugawara, overlooking a clear stream and lush trees. The most important architectural theme is to allow guests to immerse themselves in this beautiful natural setting while soaking in the natural hot springs formed by volcanic activity. To bring out the vibrant beauty of the changing seasons, from fresh greenery to autumn foliage, the color tones inside the guest rooms have been kept as subdued as possible in terms of both saturation and brightness.

At the same time, we have blended dynamic spaces, such as a massive pool and open-air baths spanning two levels, with traditional Japanese architectural techniques like kakekomi and saobuchi ceilings. Key design elements include a sectional composition that descends gently toward the river and handrails designed not to obstruct the view. For the exterior, while using traditional materials such as Japanese roof tiles and charred cedar, we strove to create a modest architecture that maintains a low visual profile within its surroundings.

Beyond simply depicting the architectural form, I focused on visualizing the experience at the heart of this project: soaking in natural hot springs while surrounded by clear flowing water and lush greenery. Through close dialogue with the architects, I carefully selected moments when the architecture and the changing beauty of the seasons come together most harmoniously.

Each CG perspective was composed from the guest’s point of view, considering what they would see and feel while relaxing in the rooms, hot springs, pool, or sauna. Natural light was also simulated with precision to reflect the actual environmental conditions of the site.

My aim was to capture both the quiet architecture blending into its surroundings and the dynamic spatial experiences within it. By creating scenes across different seasons and weather conditions, I sought to convey the many expressions and unique atmosphere of this place as faithfully as possible.
