The Paris nightscape has become a model for nightscapes around the world. Appreciation for the streets of Paris has helped to preserve and restore them to places of beauty during the day and at night. At night, the streets emerge as distinct axes of light and one wonders how far urban light planning will progress. Illuminated in white light, the La Grande Arche, gives the impression of a modern-day city. Set against a dark background, the lofty figure of the Eiffel Tower glows impressively. Looking towards Montparnasse from the top of the Eiffel Tower. The bright building in the center is Montparnasse Tower.

City Night Survey : Saitama-Shintoshin 2019.04.11　　Lin Hu + Hikaru Kimura Saitama Shintoshin is a district established around the year 2000. Centered on JR Saitama-Shintoshin Station, it is an intensively structured urban area featuring a variety of functions, including large-scale commercial facilities, a major multi-purpose arena, government office complexes, and hospitals. This survey examined how this planned city has evolved from the perspective of lighting. Nightscape over the heliport from the Saitama Government Office Complex Light Linking Spaces A pedestrian walkway system is installed around Saitama-Shintoshin Station, utilizing an active pedestrian-vehicle separation plan that allows for smooth circulation from the second-floor station gates to various facilities. While the ground level is brightly illuminated by roadway pole lights, the pedestrian walkways feature lower-level lighting such as uplights and footlights—excluding some decorative pole lights in park areas—creating distinct expressions of light for each zone.Saitama-Shintoshin Station is connected to Kita-Yono Station by a walkway spanning approximately 600m. A continuous cantilevered glass canopy allows pedestrians to walk without getting wet in the rain or being stopped by traffic signals. Along this route, there is a straight path of about 100m running parallel to the railway tracks. Here, despite the cantilevered canopy structures being identical—likely due to differing construction phases—the lighting techniques varied across three distinct types. Although the architectural design is similar, the change in lighting methods results in varying levels of brightness depending on the location. While achieving uniformity may seem important, using different…

2025.01.15-01.19 Masafumi Yamamoto + Yuichi Anzai About 65 years ago, a vast area at the foothills of the Himalayas was divided into districts for government functions, commerce, education, and residences, with separated roads, creating a landscape completely different from other Indian cities. This survey takes a multifaceted approach to examine Chandigarh’s urban lighting and nightscape, while observing the natural light expressions inspired by Le Corbusier’s architecture. ■Light RaysFirst, I quote the words of Le Corbusier:“Chandigarh is planned on a human scale. It connects to the infinite universe and nature. It is a place for all human activities where citizens can live a rich and harmonious life. Here, the radiance of nature and the heart is within our reach.”A vast paved ground is moistened by a dense white mist. About 180 meters ahead from where I stand, the High Court building faintly appears. Its enormous facade faces east and west. The sky behind peeks from beneath the portico, and the rays of light passing through it gently caress the huge concrete pillars painted red, yellow, and green, casting the morning sun on the ground. In this city, I encountered several lyrical daylight scenes. I believe this is because the philosophy of Atelier Le Corbusier in Paris, who designed this Capitol Complex, also extended to the urban layout. Until now, Chandigarh has been discussed mainly from an architectural viewpoint. However, I feel it has not been explored much from the perspective of…

Chong Qing Lighting Survey 重庆史光: Re-Celebrating History of Light 2019.07.04 – 2019.07.05　　Clement Lee + Iwata Masahiro Located in the upstream of Yang Tze Basin, Chong Qing serves as one of the manufacturing,　transportation and commercial hub of China. Caught　within rapid　infrastructure changes, this survey seeks to uncover the methods for Architectural and Lighting preservation efforts to reflect the ancient Clement Lee + Iwata Masahiro traditions from the dynasties. Ci Qi Kou Old Town highlighted with linear architecture facade lighting contrasting the light blue canvas sky of the evening Old town of Ci Qi Kou (磁器口): Cultural Hub of Chong Qing Chongqing is a technologically advanced city situated in the mountains of southwest China. With a rich history of being a major economic hub, Chong Qing was propelled to earn a place in the top 13 megalopolises of China. With the theme of understanding and exploring the cultural traditions of Chong Qing, we set out to discover its customs and efforts to preserve the rich traditions which create the unique character that separates this Sze Chuan-influenced province from the other major cities of China. We began at the heart of the city: the old district of Ci Qi Kou. This old town is currently filled with shops sells goods and traditional food of the old Chongqing. A modernized trading hub that reflects the bustling old port to trade porcelain along the Yangtze River. It was a commercial hub for pioneers back in the…

2025.11.09-11.14　Jiang Kunzhi + Lin Huangyi This survey aims to explore the interaction between Soviet culture and Islamic culture within the urban space of western Tashkent, with a particular focus on whether this cultural layering has given rise to region-specific lighting approaches and expressions of the luminous environment. Therefore, a systematic field survey and documentation were carried out across the urban areas of Tashkent. As the capital of Uzbekistan, Tashkent reflects both Soviet modernism and Islamic architectural traditions. The city features large Soviet-era public buildings alongside religious architecture that blends tradition and modernity. In addition to above-ground buildings, this survey also examined the Tashkent Metro, Central Asia’s first metro system opened in 1977, where refined lighting and rich materials create museum-like underground spaces. (Jiang Kunzhi) ■Aerial night view of Tashkent Viewed from the TV Tower, Tashkent’s nightscape appears as a network of “lines” and “points” rather than a continuous illuminated façade. The road system forms the clearest visual structure: main roads and ring roads read as linear light bands, while bridges and major intersections appear as brighter nodes, creating a legible traffic framework over the city’s flat skyline. These linear elements strongly define the city’s sense of direction and scale. In contrast, most buildings remain dark at night, with their presence defined only by entrance lighting, limited window glow, and reflected ambient light. As a result, the overall background luminance stays low, allowing a few landmarks—such as tall structures or media…
