Hamamatsu Children's Museum opened in November 2001 with the goal of providing children with healthy play, creative experiences, and a place for interaction, and of supporting the healthy development of the next generation of children and child-rearing. The objective of this project was to concept design the interiors environment, including the playground equipment, which had become outdated and outdated after approximately 18 years since its opening, and to provide safer and more comfortable services to users. "Hamamatsu Children's Museum Philosophy" Children possess an insatiable curiosity within. Hamamatsu Children's Museum aims to create a loving environment where children can fully express their true nature and play to their heart's content, safely and with peace of mind. In this environment, we hope that children will interact with many others and develop their social skills and creativity. Furthermore, we aim to foster an environment where parents raising precious children, who represent the future, can expand their mutual support network and enjoy raising their children while receiving professional support. We believe that the experiences and images children create during this psychologically stable period are incorporated into their brains' long-term memories, creating fertile soil for a fulfilling and happy life. [Social Issues/Customer Issues/Requests] 1) Renew some of the playground equipment and interiors while maintaining the facility's original management philosophy and functionality. 2) Minimize temporary closures and complete the design and construction in just one year. 3) For the renovation, we worked to utilize Tenryu timber (local timber), a method promoted by Hamamatsu City, and obtained FSC® Project Certification. The above requests were received. [Solution] 1) We concept design a playground that incorporates the local characteristics of Hamamatsu, such as its nature and industrial technology, and created mechanisms to foster interest and attachment to the community. 2) To create a "playground unique to Hamamatsu" that nurtures the humanity and learning foundations of Hamamatsu residents, we used original playground equipment and space based on theories of human development. 3) Tenryu cedar, a timber sourced in Hamamatsu City, is used for the hall, Daichi Zone (floors, walls, and some playground equipment), workshop room, and corridors. The FSC® project team, with Hamamatsu City as the manager and our company as the deputy manager, achieved the first international forest certification, "FSC® Project Certification*," for a similar public children's facility in Japan. *FSC® Project Certification ・The FSC® standard is an international forest certification system based in Germany and is the world's highest standard. ・FSC® certification means that wood from properly managed forests is guaranteed to be used. ・Hamamatsu City is particularly focused on using FSC®-certified timber as a concrete action toward the SDGs. <Our project members> [Direction] Suzuki Atsushi [concept design] Watanabe Mika [Planning] Abe Reimi [Production] Takahashi Akinobu, Ota Hironari, Ichijo Takehiro [Sales/Project Management] Ogasawara Akinori, Tashiro Haruka ~Related Links~ [Release] NOMURA Co.,Ltd. opens Hamamatsu Castle and Hamamatsu Children's Museum, the first FSC® Project certified facilities in Japan to use domestic timber
