"Marunouchi Street Park" is a project that is being carried out as a demonstration experiment of future area management, transforming "road space" into a comfortable "urban park space" in Nakadori, Marunouchi, Tokyo. The winter 2023 event will continue from the summer and examine the state of urban parks in preparation for permanent establishment, while highlighting the illuminations, a winter feature of the Marunouchi area, and providing various content perfect for the holiday season, such as photo spots for visitors to enjoy, a merry-go-round, an ice rink, and a Glass House Market with a wide selection of food and beverages. This time, the concept is "Bright Street - Nakadori in winter, where the city and everyone shines -" and we have taken measures that are in line with the SDGs and trends of the times, such as reusing each market booth used in winter 2022 and remaking the swing-shaped bench that was popular during the summer 2023 event into a photo spot with new decorations. In addition, we have worked to create content that makes use of our past know-how, such as upgrading the "Detour Bench" created in summer 2023 to a bench where you can relax while looking up at the illuminations. In addition, while the official musicians performing on the streets will continue as in the summer, we have also taken on new initiatives in terms of planning, such as inviting a portrait artist this time. In addition, as a continuation of the "Illumination Tour for the Blind" held in the winter of 2021, we held a dialogue tour in which able-bodied people walked blindfolded to deepen their understanding of the visually impaired, creating an opportunity to discuss how to make the streets more comfortable for everyone.
