Indigenous Knowledge
80%Ryukyuan salt-making (*shiokaze*) is a 500-year-old tradition where salt is harvested using solar evaporation and tidal rhythms, requiring no fossil fuels and maintaining biodiversity in coastal ecosystems. This knowledge is held by elders in communities like Ishigaki and Miyako, but is being erased by industrialization and militarization. The erasure reflects a broader pattern in Japan where Indigenous Ainu, Ryukyuan, and Hokkaido Indigenous knowledge systems are systematically marginalized in favor of state-sanctioned ‘progress.’
