This comprehensive report examines the historical and geographical evolution of Osaka’s waterfront, focusing on the artificial landscapes of Tenpozan and Yumeshima. It traces the area’s transformation from 19th-century flood control projects and coastal defense fortifications into a modern hub for international trade and global entertainment. The narrative details how Tenpozan originated from river dredging to become a social landmark, while Yumeshima transitioned from a stagnant "debt asset" to the future site of the 2025 World Expo. Through five specific case studies, the sources illustrate a recurring theme of human intervention overcoming natural limitations via advanced engineering. Ultimately, the text reflects Osaka’s enduring effort to redefine its urban identity by reclaiming land from the sea to meet changing political and economic needs.
