City Night Survey: Hanoi, Vietnam
2024.11.21-24 Chuanyi Liu + Jiang Kunzhi
Hanoi, the capital of Vietnam where history and modernity blend seamlessly. Thanks to its rich cultural heritage, it has established itself as one of Southeast Asia’s premier tourist destinations. In this city where the Old Quarter, St. Joseph’s Cathedral, and Lotte Tower coexist, we explore Hanoi’s nightscape culture through the lens of light.
Vietnam, a populous nation of 100 million people, has Hanoi as its capital serving as the political, cultural, and economic center as well as a key transportation hub. In July 2020, the Vietnamese government issued Decision No. 1129, promoting the development of the night economy and designating Hanoi as the pilot city for this initiative. The city’s rich heritage and unique cultural arts provide favorable conditions for the growth of Hanoi’s night tourism.
Hanoi’s urban lighting exhibits distinct characteristics depending on the area and function. In the Old Quarter, narrow alleys and historic buildings create a lively atmosphere with bustling night markets. The nighttime lighting here mainly consists of creatively designed decorative lights at individual shops, which enhance the vibrant energy. Around Hoan Kiem Lake, soft lights reflected on the water’s surface and the illumination of the Turtle Tower standing in the lake harmonize to create a calm and serene nightscape. In the new urban area, modern building facades and bright LED lighting present a contemporary and sophisticated city image. Dynamic light displays further emphasize the lively spirit of the area.
Night markets and commercial districts frequented by tourists are filled with Hanoi’s characteristic vibrancy and energy. Colorful neon signs, billboard lighting, and various decorative illuminations light up the streets, symbolizing the dynamism of Hanoi’s night economy. However, in some areas, concerns arise over visual fatigue and light pollution caused by high-intensity signage and excessive decorative lighting. The following sections provide a detailed analysis by district. (Jiang Kunzhi)
■ Train Street
Hanoi’s Train Street is a unique tourist spot where a train passes through a narrow alley. During the daytime, Train Street stands out as one of the most down-to-earth places in the Old Quarter, known for offering visitors a close glimpse into the daily lives of local residents. On both sides of the
tracks, houses and cafes line the street, allowing tourists to experience the locals’ distinctive lifestyle up close. The natural light harmonizes with the street’s decorations, and the sunlight streaming onto the rails creates a special atmosphere found only here. While the lively vibe is palpable, safety concerns remain due to the narrow street where an active railway still runs.
The nighttime lighting on Train Street mixes high color temperatures, low color temperatures, and even RGB lights. The overall color temperature is approximately 5000K, with the main light sources coming from decorative lights installed at cafés and street stalls along the route. Neon signs, lanterns, light boxes on shop signs, and small dot lights hanging from trees illuminate the street, providing both functional and decorative lighting. However, many of these decorative lights are simply constructed, often using bare bulbs directly exposed. Overuse of lighting is also noticeable. Compared to surrounding streets, Train Street is overwhelmingly brighter, and the strong contrast in brightness creates a striking visual impact. This interplay of light and shadow gives the nightscape of Train Street its distinctive character, making it a uniquely attractive spot. (Jiang Kunzhi)
■ Old Quarter
The Old Quarter by day is known for its narrow alleys and traditional architecture, encapsulating the history and culture of Hanoi. The streets are lined with shops selling traditional crafts, clothing, and Vietnamese cuisine, offering visitors a rich experience of Vietnam’s unique atmosphere. Bathed in sunlight, the vibrant streets convey the distinct cultural charm of Hanoi, pulsing with a rhythm all its own despite the apparent chaos.
■ New Urban Area
The New Urban Area showcases Hanoi’s modern side with a sophisticated cityscape. Spacious roads and glass-covered high-rise buildings line the streets, where natural light reflects off glass surfaces, creating depth in the architecture and enveloping the entire area in a bright and refreshing atmosphere.
At night, cool-toned façade lighting further emphasizes this modernity. Dynamic lighting effects skillfully blend with building lines, giving the structures a sense of motion. However, some buildings lack thoughtful lighting design, with visible issues such as broken fixtures and insufficient maintenance. Variations in color temperature also disrupt the overall cohesion of the nightscape.
A landmark of the New Urban Area, Lotte Tower serves as a nighttime focal point through its dynamic lighting and vibrant color changes. The tower’s crown lighting vividly colors the night sky and draws the gaze of onlookers. Yet, maintenance shortcomings cause some lights to be out and inconsistencies in color temperature remain issues to address. The nightscape viewed from Lotte Tower’s observation deck symbolizes Hanoi’s energy and prosperity, spreading out like a shimmering sea of lights across the city. (Chuanyi Liu)
lined with modern buildings.
■ St. Joseph’s Cathedral
St. Joseph’s Cathedral is one of Hanoi’s representative Gothic architectural landmarks, with its spires and arched windows strongly reflecting the influence of the French colonial era. During the day, sunlight accentuates the building’s delicate and beautiful details. Cafes and craft shops scattered around the surrounding square offer visitors a peaceful and cultural experience, adding further depth to the scenery centered on the cathedral.
At night, the cathedral is illuminated with warm-toned lighting that enhances its solemnity and sacredness. The spires and window decorations stand out under the lighting effects, drawing the attention of visitors. However, the overall lighting of the square lacks cohesion. Light leaking from surrounding shops creates a cluttered impression, and the main lighting of the square relies heavily on large high color temperature floodlights, resulting in noticeable areas with insufficient brightness. Despite this, the light emitted by the cathedral itself carries a profound breath of history, leaving a deep impression on those who visit. Its silhouette against the night sky quietly colors Hanoi’s nightscape as a landmark symbolizing the city’s history and culture. (Jiang Kunzhi)
■ Summary
The charm of Hanoi’s nightscape lies in the contrast of light and shadow created by the fusion of historic landmarks and modern architecture. Historic buildings such as St. Joseph’s Cathedral and the Turtle Tower are illuminated with warm-toned lighting, evoking a solemn and profound atmosphere. Meanwhile, modern architecture symbolizes the city’s vitality with sophisticated designs and vibrant lighting. This blend creates a unique urban landscape where tradition and innovation coexist harmoniously.
The nightscape around Hoan Kiem Lake features a distinctive contrast between the tranquil lake surface and the bustling night market, showcasing the beauty formed by the interplay of natural and artificial light, delighting viewers. Neon signs and billboard lighting bring energy to the city but also highlight challenges such as light pollution and excessive illumination.

Lighting Detectives x Glow Shenzhen
Hide and Seek with Light, a reflective art workshop
2024.12.19 Hu Lin + Xianyu Liu + Huangyi Lin
On 19 December 2024, Lighting Detectives returned to Shenzhen, promoting sustainable urban design and light pollution awareness through creative community art. Eighty participants from diverse backgrounds gathered in Lianhua Mountain Park and transformed into “light artists”.
After a five-year absence, on 2024 Dec. 19th, the Lighting Detectives returned to Shenzhen with a creative public event, Glow Shenzhen, claiming the First Gold Award in Glow Shenzhen 2024’s Infinite Illumination program.
Collaborating with China Academy Of Urban Planning & Design Shenzhen Branch and Shenzhen Illuminating Engineering Society, the workshop focused on combating light pollution and preserving natural darkness in urban environments. Eighty participants from diverse backgrounds gathered in Lianhua Mountain Park and transformed into “light artists” through hands-on experiments. Using adjustable handheld flashlight and reflective materials, we explored the delicate balance between illumination and darkness, crafting temporary art installations with eco-friendly red lighting.
Before the creative phase, organizers held a brief introductory lecture under the dome outlining the event’s core objectives. Our chief, Mr. Mende and Ms. Kasai shared the founding story of the Lighting Detectives and the past initiatives, particularly Shenzhen Nightscape 2030 event from five years ago. Attendees showed particular interest in signature programs such as Light Up Ninja, Night Walk and Children’s Workshop. At the end of the lecture, Mr. Lin Hu demonstrated the unique properties of different materials and guided participants through creative techniques.
During the workshop, participants were devided into several small groups and given three hours to create artworks. The methods of creation, materials used, and ways of presentation varied, offering a great deal of diversity. Through painting, pasting, and weaving, participants created unexpected and wonderful artworks. Even two artists specializing in paper cutting created stunning patterns. The passion of the participants exceeds anyone’s imagination.
When the artwork was finished, the sky began to darken, and we took a group photo under the twilight group by group.
In the end of creating phase, we each placed our works in the dark environment of Lianhua Mountain Park. Together, we explored and admired these beautiful artworks in the darkness. It became a part of the city’s public space, available for citizens to explore and enjoy.
This is the highlight which is a collaborative light-art masterpiece – an expansive scroll blending shadows and light. This interactive project not only demonstrated how responsible lighting can enhance urban aesthetics, but also encouraged participants to re-examine city spaces through creative play. The activity proposed fresh ideas for balancing urban development with environmental protection.
We also took a group photo in the dark, just like we did 5 years ago, during the Shenzhen Nightscape 2030 activity, in the form of the Lighting Detectives’ logo!
By merging art, ecology, and community co-creation, Hide and Seek with Light illuminated new pathways for sustainable urban design, earning recognition as a standout initiative in Glow Shenzhen’s Infinite Illumination program.
Lighting Detectives Annual gathering
2025.1.16 Noriko Higashi
In past years, we held a joint year-end activity report meeting with the Lighting Detectives’ corporate sponsors and members. However, this year we decided to hold separate gatherings. The aim was to create a more relaxed space where we could take our time to hear each member’s hopes and ideas for the Lighting Detectives’ activities in 2025—but with so much to discuss, the two-hour session flew by in an instant.
During the Busan presentation, member Kubota shared vivid impressions of the bustling local markets and the evolving Gamcheon Culture Village, where the shift to LED lighting is putting the area’s photogenic charm at risk. He also described two contrasting beach areas: Haeundae Beach, brightly illuminated all the way to the shoreline, and Gwangalli Beach, which—though lacking direct beach lighting—is still brightly lit thanks to surrounding signage and ambient light from the nearby entertainment district.
from Kyoto to join the event.
During the review of the Kagurazaka fieldwork, which was conducted in two groups, reports were given by Lighting Detectives members Kotani and Tawara, who served as group leaders.
Kotani, leader of Group 1, titled their route the “Kagurazaka Alley Immersion Course”, focusing their walk primarily on the backstreets. According to her report, as participants made their way from Iidabashi toward Kagurazaka, they first encountered an overwhelming number of brightly lit signage at the entrance, which felt inconsistent with the traditional image of Kagurazaka. However, once they entered the narrow alleys, they found that many restaurants had thoughtfully designed lighting, leaving the impression that this is a neighborhood with a high sensitivity to light design.
On the other hand, the group was disappointed by overly bright white streetlights and media billboards continuously streaming advertisements, which disrupted the otherwise atmospheric nightscape.
Group 2, led by Lighting Detectives member Tawara, explored what they called the “Alley & Shopping Street Route,”which extended deeper into the Kagurazaka area. Their report highlighted issues such as protruding vertical signs reminiscent of those in commercial downtown districts, the use of colored lighting—pink and green—to illuminate street trees in an attempt to create vibrancy, and inconsistencies in streetlight color temperature between roadways and sidewalks.
The group expressed a clear wish for Kagurazaka’s historic nightscape to remain one of atmospheric dimness, with cozy, walkable alleys. Elements that contradicted this expectation were met with a resounding “No.”
During our discussion on ideas for the 2025 night walk survey, several locations were suggested. Within Tokyo, participants expressed interest in newly developing areas such as Takanawa Gateway City and Shibaura, the industrial nightscapes of Kawasaki, as well as Tennoz, Omotesando to Shibuya, Kichijoji, and Nakano. Suggestions for destinations outside of Tokyo included Expo 2025 Osaka, Umekita in Osaka, and various areas in Kobe and the Kansai region. Some members also shared a desire to visit more rural locations to enjoy star-filled skies, traditional fire festivals, or fireworks displays.
While we had hoped to hear from everyone about their ideas and preferences, two hours simply wasn’t enough. Whether it was the full agenda or the richness of each topic, time ran out before we could delve deeply into everyone’s thoughts. It became clear that future meetings will need to be at least three hours long.
Having our Lighting Detectives members gather at the beginning of the year to share ideas about future activities was a refreshing and valuable experience. Moving forward, we’ll work with our planning team (SQUAD) to design city walks that are both enjoyable and meaningful.
We hope you’re looking forward to another inspiring year with the Lighting Detectives. (Noriko Higashi)
