If you don't know much about Yumeshima, please refer to it first.   → For breeding little terns


On the artificial island "Yumeshima" in Osaka, where the Expo 2025 is planned, reed beds and salt marshes have been created by the wild power of many years, and it has become a paradise for many creatures. Very rare creatures are also breeding inside.

However, reclamation work is progressing at a rapid pace in the area scheduled for the Expo, and the entire environment is about to be lost.
Why don't you stop this construction plan and turn the wonderful nature of Japan born in Yumeshima into a "living ecological exhibition area" at the SDGs Expo?

Leaving the reed beds, wetlands and their surroundings in Yumeshima, we can see the following during and after the Expo. You can show people all over the world this wonderful nature.

10 reasons I want you to keep

1) The little tern, which is endangered internationally, will come to Japan in the spring, form a group colony in the bare land of Yumeshima, raise chicks, and leave for the summer again.

2) Yumeshima's wetlands are an important resting place during the spring and autumn migration seasons for the Shigi Chidori (Scolopacidae) friends who migrate from Siberia to Southeast Asia and Australia.

3) In early summer, SEITAKASHIGI(Himantopus himantopus), which has only a few breeding grounds in Japan, breeds in a sandbank in the reed bed of Yumeshima.

4) From autumn to winter, many ducks come to Yumeshima Pond, but among them, the largest and beautiful common TSUKUSHIGAMO(Tadorna tadorna) fly in Honshu.

5) In the pond in the reed bed, the aquatic plant "Ditch-grass", which was already considered extinct in Osaka, was discovered and blooms white flowers in early summer.

6) There are many insects in the reed bed, and small birds that prey on them gather, and birds of prey that aim for them visit, and wild dramas are played all year round.

7) Swallows born in remote areas make a group roost in the reed bed in early August before migration. The sight of young swallows flying around in a group is a masterpiece.

8) Yoshihara is Ashihara. As it is also called "Naniwagusa", it was a symbolic natural landscape in the local Osaka, but now there is a large-scale reed field only on a part of the Yodogawa riverbank. This reed bed, which symbolizes the ecosystem of Osaka, creates a pleasant green space in the summer.

9) In the Osaka Red Data Book 2014, Yumeshima is among the 16 hotspots that should be left, along with the neighboring Nanko Bird Sanctuary (currently Nanko Bird Sanctuary). There is only Yodogawa in Osaka city. It's one of only two places. We already knew how valuable it was as a natural ecosystem.

10) Nanko Bird Sanctuary is one of the few artificial tidal flats and is popular with visitors from overseas, making it an indispensable destination for travelers who want to see the nature of Japan and Osaka. It is the vast wetlands of Yumeshima that are close to each other that support the abundant types and numbers of wild birds in Nanko Bird Sanctuary.

In this way, even if you give it roughly, the reed beds, salt marshes and ponds in Yumeshima are too wasteful to reclaim and lose. During the Expo, you can see that it is a precious nature that people around the world want to see, and that it is worth leaving as a place that symbolizes the "future society that shines with life" with the SDGs.
