Launched in 2019, "Marunouchi Street Park" is a social experiment project designed to explore the future of Marunouchi Nakadori Street and how it can be utilized. Based on the spatial concept of "Connecting Summer Streets," the project focused on Marunouchi's distinctive culture, community, and people. Each of the three approximately 300-meter blocks was designed with a unique theme, reflecting the city's unique connections to culture, the community, and people. Block 1, located in front of the Maru Building, was themed "Sports & Relax," creating a wellness street where people can exercise, relax, and refresh themselves, featuring a ping-pong counter and a deck with balance balls. Block 2, themed "Enjoy Eating Out," offers the enjoyment of dining in a parklet surrounded by fairwood while enjoying outdoor live painting by artists based on the SDGs and street piano. Block 3, themed "PARKcation," featured a grass-covered workspace and bicycle counter, reminiscent of swaying grassy hills, and a summer beach resort scene using Okinawan coral sand, all of which were well-received. In terms of safety and health, we implemented special infection control measures, including measures against strong winds from typhoons and building winds, and spraying the entire facility with an antiviral coating. (Event period: August 2-September 12, 2021) Regarding our efforts with fair wood: Cedar and larch Nishikawa lumber thinned in Hanno City, Saitama Prefecture, are used for counters and other fixtures. The design took advantage of the distinctive grain and color of the cedar heartwood, known as "black heart," and structural plywood. After the event, some of the wood used will be reused, and when its usefulness is complete, it will be returned to nature, where it will be recycled for seedlings, reforestation, and forestry. <Our project members> [Project Director] Suzuki Echiyo [Sales Promotion] Ishiyama Shigeyuki, Yamamoto Hitomi [design, layout] Matsubara Miwa, Kaizawa Ayuko, Sudo Ryo, Sakuma Tonoeki [Planning] CIC: Saito Yusuke [Operations Management] CIC: Ando Kaoru [Production] Marumori Yukio, Yamaguchi Yuta, Yoshida Takuto ~Related Links~ [Announcement] ・"Marunouchi Street Park Illumination Tour!" sponsored NOMURA Co.,Ltd.
