It is not the first such island in the bay (see Umi-no-mori :ja:海の森公園). At current fill rates, there will be no more room for waste landfill in the bay without affecting shipping lanes by around 2050; likewise, Osaka Bay and Ise Bay are slowly being consumed by waste landfill islands, e.g. Rinku Town.
History
The island was originally conceived in the 1930s as a site for a new Tokyo Municipal Airport to replace Haneda Airport. The airport plan was finalized in 1938, and work on the island began in 1939 but fell behind schedule due to resource constraints during World War II. The airport plan was officially abandoned following the war, as the Allied occupation authorities favoured expanding Haneda rather than building a new airport.
A public beach opened on the island in 1947 when the "Yumenoshima" name was adopted. The beach closed in 1950, and from 1957, the island was used for garbage disposal (mainly plastic at the time).

Yumenoshima is a fairly small district, and contains:
- Yumenoshima Park, a public park with an array of facilities, including a tropical botanical garden, a sports complex, a barbecue area, a colosseum, a yacht marina, a track and field stadium and a ramen stand
- Yumenoshima Stadium, a football and athletics stadium used for youth competitions and lower league football matches
- Yumenoshima Baseball Field, a baseball field for local youth teams
- Koto Incineration Facility, an incineration facility for Koto Ward
Today, Yumenoshima also houses the Daigo Fukuryū Maru, a wooden fishing boat exposed to nuclear fallout during the Bikini Atoll test in 1954; the boat was modified as a training vessel following the exposure and later abandoned near Yumenoshima.
