Kyu-Karuizawa, within Karuizawa, is an area that has long accumulated history and culture. In this work, the deep flow of time that runs through the land is portrayed through the play of light and the subtle movements of nature. By capturing the delicate expressions of light created by the forest—light filtering through the trees, shadows of leaves swaying in the wind, reflections on the water’s surface—we have made visible the gentle passage of time that flows through this place. Filming was also carried out throughout the year, and by layering the changing light and natural expressions of each season, we woven into the footage the depth of time held by Kyu-Karuizawa. Through sound design that carefully layers natural sounds such as the forest wind, birdsong, and flowing water, the work creates an immersive feeling, as if one were standing within the forest.
