Yumeshima
an artificial island in Konohana ward, Osaka, Japan
Yumeshima (夢洲) is an artificial island in Osaka Bay. It is part of Konohana-ku (此花区), one of the 24 wards of Osaka, Japan. It is near the mouth of the Yodo River. When all the landfill is completed the total area will be 390 hectares (960 acres).
It was the site of Expo 2025, a World Expo which operated from April 13 to October 13, 2025.
Overview
Yumeshima is located southwest of the island of Maishima, in the westernmost end of Osaka City. It is one of the three artificial island areas targeted by the “Technoport Osaka” plan formulated in 1988 with the aim of developing a new city center.
There are two high-standard container terminals with a depth of 15 meters in the south of Yumeshima, but most of the area is unoccupied. The southern end of Yumeshima is positioned as a logistics center. In the early 2000s, the island was proposed as the Olympic Village in Osaka's bid for the 2008 Summer Olympics.
This brief starts where responsible research should: with the source description of “Yumeshima” as an artificial island in Konohana ward, Osaka, Japan. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as an artificial island in Konohana ward, Osaka, Japan. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Mar 11, 2026. The linked authority identifier is Q11431648. Authority coordinates are 34.652, 135.390. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2025, 1988 and 2008.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
