Zurich ⇒ Bern ⇒ Basel2018/04/12-04/17　　Yumi Honda + Kyoko Takubo We visited Switzerland in search of places with light where people gather. Celebrating the longawaited arrival of spring, we found that more people than we expected were relaxing outdoors from morning until night. During the day, they enjoyed the abundant nature and beautiful cityscapes, soaking up the natural light. At night, people were chatting and laughing in a soft, gentle light. We climbed a dark hill for an elevated nightscape shot, but even there, it wasn’t tourists but locals who were gazing at the nightscape. We were able to find a city light in Switzerland that makes you want to spend a long, leisurely time there. People enjoying the sunset on the shores of Lake Zurich People Gathering on the Riverside in Basel, with Beers in Hand ■Waterside at DuskOn a warm spring evening, people gather on the shores of Lake Zurich. In open areas with a view, everyone enjoys the passing of time in their own way—a unique luxury. After the sun sets and the sky turns indigo, historical buildings from the Middle Ages are softly lit and reflected on the water’s surface. The reason this atmosphere can be enjoyed comes from a combination of historical background and urban planning.First, the number of cars is overwhelmingly small compared to other cities. The city is not obstructed by wide roads or traffic jams, so you can feel close to the river,…

2022.11.4-5 Sachiko Segawa Surprisingly, this survey of the Sawara district marks the first time the Lighting Detectives have conducted an investigation within Chiba Prefecture. The team focused on an area designated both as an Important Preservation District for Groups of Traditional Buildings and as a Landscape Formation District. Here, the townscape of merchant houses, which flourished from the Edo period thanks to river transport on the Tone River, still remains. Located about 70 km from Tokyo Station and slightly inland from the Tone River, the Sawara district of Katori City once thrived as a merchant town, to the point it was said to rival Edo itself. However, the town declined during Japan’s period of rapid economic growth. Following a townscape survey in 1974, the value of its historic scenery was reappraised. Today, leveraging its convenient location—just two hours from Tokyo and one hour by train from Narita Airport—the area is being redeveloped as a tourist destination. For this survey, the team limited their scope to the townscape along the Ono River and conducted a nightscape survey. ■Uniquely Designed Lighting Fixtures From JR Narita Line Sawara Station, as we walked toward the Ono River, we were greeted by a bollard topped with a monkey. “Why a monkey…?” we wondered, but as we continued upstream along the river, we encountered bollards adorned with all sorts of figures: rabbits, carp, children, frogs, Ebisu, and more—each one different, with no two alike. These uniquely…

2025.06.26 Yumi Honda +Qiaoxi Wang+ Momoe Nomura We observed and recorded the nighttime light environment of the newly developed commercial complex Senkyaku Banrai in the Tokyo Bay Area and its surrounding public spaces (green plaza, station area, and Gururi Park). We conducted a multifaceted analysis, including the placement of lighting fixtures, illuminance, and the impression of the space, to determine how light affects the atmosphere of the facility and the city in the Toyosu area, which is being developed as a tourist hub. The Toyosu area is a point of interest where the latest urban spaces and the lively atmosphere of shitamachi (old downtown) coexist due to redevelopment. We walked through the area around Toyosu Market Station, the green plaza, and Gururi Park, observing how light design impacts the impression, comfort, and safety of the town. ■Senkyaku Banrai Senkyaku Banrai is a commercial facility that opened in 2024 next to the Toyosu Market. It’s a spot where both tourists and local residents can enjoy the array of restaurants and souvenir shops. Through architecture and lighting design incorporating traditional Japanese motifs, it exudes a uniquely Japanese warmth and vitality, even within the contemporary urban nightscape. The lighting plan inside the facility is unified, as befitting a new commercial complex, and was designed with both aesthetic appeal and functionality in mind. The main path lighting uses warm, incandescent colors, creating a nostalgic atmosphere reminiscent of a Showa-era shopping street. This fosters a…

In the middle of Tokyo is the Imperial Palace, a haven for runners and tourists, alike. The lighting in the palace outer garden and nearby Wadakura Fountain Park has been renewed and replaced with environmentally conscious LED fixtures. We surveyed the unique pocket of darkness that surrounds the Imperial Palace along with lighting environment of nearby parks and roads. Imperial Palace Outer Garden. The fancy pole lights in the outer garden are originally gas lamps, but the light source has been changed to high-pressure sodium lamps and now upgraded to LEDs. The average lux level is only 1-2lux along the paths lined with these LED fixtures, but inside the fixtures are 6, 26watt LED modules all pointed in different directions. This application helps to spread the light around without making a too bright, but comfortably dim atmosphere. Daikancho Street Daikancho Street runs along the north side of the palace grounds, is a much narrower street and pedestrian sidewalk compared with the rest of the facilities surrounding the palace. Along the tidy, hedged sidewalk, streetlights are placed at 3-meter intervals. Mostly for crime prevention, the lights are very bright and glaring. Ohtemachi Entrance The Ohtemachi Entrance area leads to an inner palace garden and is surrounded by a main arterial road on the outside, for a very open and accessible area. Most lighting is road lighting, mounted on 10-meter tall poles arranged down the middle of the street, but plenty bright…

2022.10.27　Genki Watanabe+ Chuanyi Liu+ Yuki Ito This Tokyo night walk survey took place in Shimokitazawa, a neighborhood especially popular among young people. Known as one of Tokyo’s most culturally rich districts, the area is filled with vintage clothing shops, eateries, theaters, niche cinemas, and art galleries.The Lighting Detectives previously conducted a survey here in 2009. This time, we examined how the area has changed since the Odakyu Line was relocated underground. We also focused on the newly developed Shimokita Senrogai area, which opened on May 28, 2022, assessing its lighting design and comparing it with the older shopping streets to explore the contrast between new and traditional urban atmospheres. ■Map around Shimokitazawa Station With the Odakyu Line moved underground, a new neighborhood called Shimokita Senrogai was developed between Higashi-Kitazawa Station and Setagaya-Daita Station. Driven by the desire to support the community, redevelopment progressed step-by-step while listening to local residents’ voices. The entire area officially opened on May 28, 2022.Alongside the railway line, new facilities such as daycare centers, a hot spring inn, commercial spaces, student dormitories, and event venues were established. ■Development of Shimokita Senrogai The Shimokita Senrogai area we surveyed is a newly developed space created by moving the Odakyu Line underground. It was designed with the intention of reconnecting the northern and southern parts of the neighborhood that had previously been divided by the railway tracks, resulting in developments that encourage smooth pedestrian circulation throughout. The development features…
