Situated in Chuo Ward, Tokyo, the Honnomori-Chuo cultural complex is home to the Kyobashi Library and Local Museum, as well as a multi-purpose hall and a cafe. Spanning six levels above ground plus one subterranean level, the main building is designed as a multilayered space in the image of a forest, and has at its heart a concept of being a "Lifelong learning space for the area to be enjoyed by children and adults alike, where history and culture can be passed on into the future". The city center location of the facility is surrounded by offices, restaurants, and high rise residential blocks, and since its opening in December 2022 it has been widely used by a broad range of people across all ages.

The exterior lighting scheme was designed to complement how the buildings have been positioned in a way that effectively accentuates the warmth of the trees around it, whilst also maintaining safe illuminance levels and generating a sense of comfort and warmth. The "Tsudoi-no-Mori" which can be accessed from the second floor is a restful space with thickets of grass, where visitors are able to sit and read on a bench or enjoy a gentle stroll. There is a rooftop garden with an observation deck on the sixth floor, where people can enjoy a relaxing and comfortable space as they gaze out over the metropolitan cityscape.

The "Tsudoi-no-Mori" and the rooftop gardens are lit by luminaires which effectively control brightness whilst producing a light to accentuate their setting, such as LEDioc APPROACH QUALLIS type-D approach lights and LEDioc UNO floodlights, with the considered selection of luminaires appropriate to each setting and area resulting in a lighting scheme which is at one with its verdant surroundings.
