Diriyah, KAFD and Metro stations Riyadh2025.11.16 – 11.18 Gita Listia The purpose of this Riyadh lighting survey is to explore the characteristics of old urban areas and new developments in KAFD Riyadh, with a particular focus on their metro stations. The study aims to understand how each area expresses its identity through public space lighting and how lighting strategies are applied in major infrastructure such as metro station. ■Diriyah Diriyah is a historic area on the north-west side of Riyadh and one of Saudi Arabia’s most important cultural heritage sites. Located along Wadi Hanifah, about 15 km from central Riyadh, it reflects the early history of the city. Today, Diriyah is being developed into a vibrant heritage, cultural, and lifestyle destination, where historic preservation is carefully combined with modern urban design. The lighting in Diriyah is designed to be subtle and heritage-sensitive. Very warm white tones are used to complement the Najdi mud-brick architecture, creating a calm and welcoming night-time atmosphere. Pole lights and bollards in Diriyah feature distinctive shapes, patterns, and warmer colour temperatures compared to typical street lighting in other parts of Riyadh. This traditional lighting character clearly signals that visitors are entering a cultural and heritage area. ■At-Turaif At-Turaif is the birthplace of Saudi history and represents the cultural core of Diriyah. It is recognized as a UNESCO World Heritage Site. Lighting at At-Turaif is highly restrained and conservation-focused. Soft grazing and wall-washing techniques are used to gently…
2023.01.20-01.22 Yuichi Anzai+ Chuanyi Liu ■Kozushima Village Kozushima is located about 180 kilometers south of central Tokyo with a population of about 1,800. The terrain is complex, with almost no flat land. The village is located in the center of the island at the foot of Mt. Tenjo. The impetus for the starry sky protection activities on Kozushima came from a comment made during a student internship program by the Tourism Foundation in 2016, that the night sky was as beautiful as a planetarium. The starry sky, a common sight on the island, has become a tourism resource. An island-wide effort to protect the sky began. Specific efforts include replacing streetlights and security lights with fixtures with 0% upward luminous flux and 2,700K color temperature, holding explanatory meetings for residents and regular workshops with experts to gain their understanding and cooperation in light pollution and starry sky protection activities, training islanders as guides, and holding star gazing events to protect the night sky from light pollution and communicate the appeal of the starry sky both on and off the island. The island is also working to protect the night sky from light pollution and convey the charm of the starry sky to the public. The “Light Pollution Prevention Ordinance to Protect the Beautiful Starry Sky of Kozushima Village,” which specifies the responsibilities of residents and businesses to prevent light pollution, will be enacted in 2019, and rules are being developed to…
In front of the main gate to Senso-ji Shrine lies the neighborhood of Asakusa. One of Tokyo’s most popular entertainment districts, Asakusa flourished with kabuki, opera, and comic storytelling from the Meiji Era to the end of WWII. The Lighting Detectives discovered a variety of decorative streetlights and a lighting atmosphere fitting for this lively cultural destination. Upon entering the famous Kaminarimon, the Nakamise approach proceeds towards the shrine with bright-white, fluorescent-tube illuminated signage lining both sides. After navigating this corridor, walls of softly glowing lanterns come into view. The lanterns once lit with fire were replaced with incandescent bulbs and now fluorescent lamps. In popular neighborhoods like Shibuya or Roppongi, architectural facade lighting or neon signage fills the vertical space and “street lighting” is virtually non-existent. However, a variety of decorative streetlights festively illuminate the streets of Asakusa for a very fitting lighting environment. Pub signage and lanterns dispersed along the dark streets of Asakusa create an uncanny charm in this neighborhood. Roadway lux levels are a fairly dim 10-16 lx, but the red lanterns hanging from the eaves of establishments dig up affection for this old town.
Because of previous colonial rule and occupation by Spain, USA, and Japan, many different cultures are accepted in the Philippines. As with architecture or cuisine, the uniquely arranged culture is also visible in the lighting environment. But behind the bright lights and in the shadows, we also saw a gap in the standard of living. For many people the church is a stronghold in their lives. The walls of this church were brightly lit with fluorescent lights and for relief from the heat several fans are also mounted on the walls, a nightscape very familiar in Asia. The floodlights bath the facade in featureless, flat light. In the area of town where Spanish architecture is still preserved hang sodium lamps, giving everything, walls, ground, and buildings an orangish glow. The dark green vegetation by the day is lost, but the historical atmosphere of the street seems like a scene out of a period movie. In the poorer areas of the city burned out streetlights are everywhere, but in the wealthier areas high-rise apartments and office buildings stand tall and just like in any other big city, there is a lack of individualism in this nightscape. Compared to the intensity of light in adjacent neighborhoods, the economical gap is prominent.
2024.05.16 – 05.19 Mari Kubota+ Noriko Higashi Busan, South Korea’s second-largest city, is one of the world’s major port cities. In recent years, it has also gained fame as a hub for tourism and film. We surveyed the lighting in Busan, which is also a member of LUCI (Lighting Urban Community International). South Korea is a close neighbor, just 1.5 hours from Tokyo by plane, making it a popular destination for quick and affordable trips. Busan, the second-largest city in South Korea, is not only a tourist destination but also a major port and an entertainment center, hosting film festivals. As a member of LUCI, Busan has been focusing on urban lighting as part of its urban planning. In 2015, the city developed an extensive overview of its nightscapes, resulting in the Busan Urban Light Policy for 2030. This policy has been updated several times, reflecting the city’s ongoing efforts in implementation and improvement. The guidelines divide Busan into several zones, each with lighting tailored to its specific characteristics.We traveled to Busan to assess whether the city’s lighting contributes to safety, beauty, attractiveness, and the local economy at night. ■Jagalchi Market Jagalchi Market is South Korea’s largest seafood market, selling both fresh and dried fish. After purchasing seafood on the first floor, visitors can have it cooked and served on the second floor. The market attracts many tourists. White lights are used to illuminate the seafood, making it look as…
