Ogo Bamboo Project, Ogo-cho, Kita Ward, Kobe
JPKobe (北区), Japan
A community group based in Ogo-cho, Kita Ward, Kobe, that since 2019 has been clearing neglected bamboo groves and putting the bamboo to use. Left alone, bamboo encroaches on fields, degrades the landscape and shelters crop-raiding animals, so continuous cutting is needed to return the hills to open, managed satoyama. Under the motto "tasty and fun", bamboo and shoots are upcycled instead of discarded — into domestic menma, bamboo craft and the transmission of those skills, and fertiliser made from bamboo chips. Its bamboo-chip compost is used in the Kobe Compost Project's public workshops.
