Tokyo’s nighttime environment has been enhanced through large-scale projection mapping and vibrant lighting displays designed to boost nighttime tourism and enliven public spaces after dark. Key initiatives include the Tokyo Night & Light projection on the Tokyo Metropolitan Government Office building—the largest of its kind globally—and seasonal illuminations along Roppongi Hills, Marunouchi’s Nakadōri, and Shibuya’s Blue Grotto. 

Iconic landmarks such as Tokyo Tower and Tokyo Skytree feature dynamic, culturally significant lighting schemes year-round, combining aesthetics with efforts to minimize light pollution. Despite a pandemic-induced decline in overall nighttime brightness and fewer neon signs, these lighting innovations help transform Tokyo’s nightscape, making it a memorable destination for residents and visitors alike. The use of advanced lighting technology not only brightens the city but also supports the nighttime economy by attracting crowds and encouraging after-dark activity
