The Shibuya DAO Hypothesis (2000):

Abstract

In approximately the year 2000, the author conceived and partially implemented a multi-layered community economic system centered on Shibuya, Tokyo. The system integrated real-time human broadcasting, local media production, a unified community coupon currency, youth-driven cultural monitoring, and digital education — years before the terminology of "DAO," "Web3," "UGC," or "creator economy" existed. This paper documents that original conception, analyzes its structural architecture, and demonstrates its direct lineage to the author's current work: the Hikari Currency (光貨) ecosystem and the ECHO AI Artist platform. The Shibuya system was not understood by contemporaries. It is understood now.
