This project involved the concept design, interiors renovation, and environmental features of the "Children's Corner" at Nakano City Central Library, located a 10-minute walk from Nakano Station. Our goal was to create a space where parents and children can feel comfortable and where the joy of books can flourish. In the raised area, we created and installed benches, a bookshelf for picture-story shows, and wooden motifs, as well as rotating blocks and a mechanism for measuring height. We also designed and produced a bulletin board with a mailbox, a hemispherical chair, and a movable bookshelf, and used "Tama wood," a local wood source in Tokyo, to create the wooden furniture, in line with the concept of wood education. We also produced 11 types of book stands, including original characters from the Central Library, to create a space that is both "playful" and "warm."
