Roadmap for Conservation and Creation of the Natural Environment
at the 2025 Japan International Exposition Osaka, Japan(Osaka-Kansai Expo’)≪The main point≫
1：In developing the venue, the current waterfront at the planned Water World
site will be preserved, and concrete and other materials will be used onlyfor the portion bordering the venue.
２：After the exposition, the site will be restored to its original condition andleft to the resilience of nature, with minimal restoration.
３：Establish a council of government, experts, and citizen groups to launch acommemorative project for the Expo to promote the restoration of naturein Yumeshima and the interaction between people and nature.

Our Vision
Yumeshima, designated as a biodiversity hotspot (rank A),
should be further nurtured and developed into a nature restoration
project that symbolizes sustainability in the Osaka Bay area
through the Osaka-Kansai Expo, whose theme is "Designing
future society for our lives".
The principle of the project is to leave the site to the resilienceof nature and watch over it. It will enhance Osaka's "dignity ofcity" and foster interaction between people and nature while
minimizing public financial investment.
Through collaboration among citizens, government, andbusinesses, the former site of the Expo will become a legacy of

Schedule to target year of SDGs

The process leading to the roadmap proposal
Nature Conservation Society of Osaka has conducted a total of more than 100 field surveys in just over threeyears since 2019. We have been conducting advocacy activities, including issuing a request for environmental protectionof Yumeshima to relevant organizations in November 2018, as well as the "Scoping Document from Citizens" (August2019) and "Our Draft Environmental Impact Assessment (Biodiversity)" (August 2021) for the Environmental Impact
Assessment of the Osaka-Kansai Expo, and as well as a request to stop the introduction of earth and sand other thanwaste, which is the original purpose of landfill, for the development of the Expo site (December 2019 and February 2020).
These activities were reflected in the Mayor of Osaka's opinion on the Draft EIA.
“Since a wide variety of bird species have been recorded in Yumeshima, a roadmap of details of environmental
arrangement and schedule, etc. that takes into consideration the habitats of these birds should be prepared by the startof construction, while listening to the opinions of experts, etc., to preserve and create a diverse environment includingwetlands, grasslands, and sand and gravel areas.” (Feb. 9, 2022)
Three leading Japanese environmental groups (Wild Bird Society of Japan, Nature Conservation Society of Japan,and WWF Japan) also issued a statement calling for the opinions of mayor of Osaka to be embodied as soon as possible(March 22, 2022).
Despite the mayor's opinion, the Port Authority is proceeding with reclamation work on the habitat of these precious
birds and plants. Therefore, we filed a resident audit request and demanded that the construction be stopped (April 7,2022). The audit result (May 27) stated that there was "no reason for the request" because the construction was thedefault policy, but also pointed out that the Expo Association was required to make efforts to preserve and create adiverse environment after the construction.
We are very concerned about the fact that only existing facts of development are being accumulated while theroadmap is not being developed by the Expo Association, and we have decided to present a roadmap from our side.
<Left figure> Initially, weproposed that the Expo beheld at the site of theproposed IR, which would
significantly delay its openingand protect the naturalenvironment. That sentimentremains unchanged today.

Yumeshima is the key to the natural restorationof the Osaka Bay area
Nature Conservation Society of Osaka was founded (1976) as a citizen's
movement to realize the Nanko Wild Bird Park. Reflecting the spread of
citizens' voices calling for the restoration of nature in Osaka Bay, the green
space is also being developed. Among these, Yumeshima has a large area withgreat potential and a track record of animals and plants that have become
established.
Creating a major flow of natural restoration in the Osaka Bay area, which
once experienced serious pollution, will enhance Osaka's "status of city”.
