The Blue & Green Art Project initiated its activities in 2020 with the goal of fostering regional sustainability through the connection of sea and land. This time, we introduced the perspective of wellbeing. The theme for this year's project was "Well-being by Sea and Land: Happiness is Found in Handicrafts". This thesis focuses on ‘Sustainable Handicraft Tradition and Design in Yamaguchi’, examining the mental, physical, and social wellbeing that handicrafts bring to people. It explores the dilemma between conventional handicrafts and design, delving into the study of wellbeing. Simultaneously, it archives presented in the exhibition ‘Happiness is Found in Handicrafts’ and explores new expressions of handicrafts. Concerning the tradition and transmission of handicrafts, the workshop was revealed as both a place of encounter and a valuable tool for discovering the inheritors.

This paper focuses on the Blue & Green Art Project, which has been implemented from 2020 to the present, in relation to the Agri-Art Festival, which was the premise of the project, and its activities on regional revitalization and development.The project focuses on symposiums and exhibitions of artworks, which are activities about regional revitalization and development by connecting the sea and land, while committing to the SDGs. In particular, the report discusses the works in the exhibition "A Journey of Fashion through the Sea," which was inspired by the symposium held in March 2022. For sustainable design, we will focus on the traditional Japanese clothing and dyeing and weaving techniques. The project focused on traditional Japanese clothing and dyeing techniques such as sakiori, tsuzure, saki-knitting, patchwork, and herb-dyeing for sustainable design. The project also included the upcycling of masks provided by the Ministry of Health, Labor, and Welfare before they were discarded, as well as oyster pipes and other flotsam collected from beach cleanups. The project also upcycled masks provided by the Ministry of Health, Labor and Welfare before they were discarded and oyster pipes that had washed ashore from beach cleanups. A sakiori weaving workshop was also held to help visitors feel the environmental issues of the sea and land as their own problems. The event was short-lived, but we hope that future activities will be more active and it was effective in raising awareness among the visitors as well as the organizers as a foundation for future activities.
