The enchanting spectacle of traditional Japanese festivals, often featuring vibrant displays of fireworks and illuminated floats, is deeply ingrained in the nation's cultural heritage. These events, however, are increasingly raising concerns about light pollution and its potential impact on children's health. The increasing intensity and duration of artificial light at night (ALAN) during these festivals disrupt the natural circadian rhythm, the internal biological clock that regulates sleep-wake cycles and various physiological processes. Studies have shown a strong correlation between exposure to ALAN and sleep disturbances in children, leading to difficulties concentrating, impaired cognitive function, and increased risks of obesity and other health problems. Furthermore, excessive blue light emitted from artificial sources, particularly LED lights commonly used in festival illuminations, can suppress melatonin production, a hormone crucial for regulating sleep and promoting overall well-being. The impact is especially profound in children, whose developing nervous systems are particularly sensitive to such disruptions. While preserving the cultural significance of these festivals is paramount, finding a balance with the need for public health is crucial. Several solutions are being explored. These include implementing stricter regulations on the intensity and duration of lighting, promoting the use of amber or warm-white LED lights which emit less blue light, and educating the public about the potential harms of ALAN and encouraging responsible light usage. Some municipalities are experimenting with creative lighting techniques that minimize light trespass while still retaining the visual appeal of the festival. For example, using directional lighting aimed specifically at the floats and minimizing stray light is gaining traction. The challenge lies in finding innovative ways to reduce the negative impacts of light pollution without compromising the traditional aesthetic and celebratory spirit of these beloved events. Ultimately, safeguarding children's health while preserving cultural heritage requires a collaborative effort. This includes collaboration between local governments, festival organizers, lighting professionals, and the community as a whole. Through open dialogue, innovative solutions, and responsible planning, it is possible to strike a harmony between vibrant cultural celebrations and the health and well-being of future generations.
