Sakishima, Artificial island in Suminoe-ku, Japan.
Sakishima is an artificial island in Osaka Bay connected to the mainland through bridges and an underwater tunnel. The island features modern buildings, commercial spaces, and residential areas built on reclaimed land.
The project started in 1977 as part of Osaka's land reclamation efforts to expand urban development. The island was gradually built up through systematic landfill and infrastructure development.
The island functions as a commercial and residential district, representing Japanese engineering capabilities in creating sustainable urban spaces from reclaimed land.
The island is accessible by car through an underwater tunnel and by rail via a metro line. Visitors should plan for adequate time to explore the various areas, as the site is quite large.
The area will host World Expo 2025 on a 155-hectare site. A notable feature is the 700-meter diameter wooden roof spanning the pavilions.
