Japan Releases Eight Crested Ibises Into Wild in Ishikawa in Major Conservation Milestone

In a landmark conservation achievement, Japan has released eight endangered Crested Ibis into the wild in Hakui city, Ishikawa Prefecture , marking the first such reintroduction on the country’s main island in decades and a significant step forward in restoring a species once lost from the nation’s ecosystem.

The birds were released in a carefully managed ceremony attended by members of the Imperial family, including Crown Prince Akishino and Crown Princess Kiko , highlighting the national importance of the initiative. The ibises emerged from individual wooden cages before taking flight over the Noto region, an area still recovering from the January 2024 earthquake , where officials hope the programme will also serve as a symbol of ecological and regional revival.

The Crested Ibis, known in Japan as Toki (Nipponia nippon) , was once widespread across East Asia but disappeared from the wild in Japan due to overhunting, pesticide use, and habitat loss . The last native wild bird in Japan is believed to have died in 2003 on Sado Island, after years of population decline that began in the Meiji era.

The species’ recovery has been made possible through international breeding cooperation , particularly after China provided breeding pairs in 1999, enabling successful captive reproduction. Since then, conservation centres on Sado Island have become the core of Japan’s breeding programme, steadily increasing population numbers to several hundred birds.

The newly released ibises were bred in captivity and gradually acclimatised to natural conditions before being set free. Authorities confirmed that additional birds are also being prepared for future release as part of a phased expansion strategy.

Officials emphasise that long-term success depends not only on continued releases but also on large-scale wetland restoration and the rebuilding of rice-field ecosystems that provide food and nesting habitats for the species.

Conservationists describe the development as one of Japan’s most important biodiversity recovery milestones, reflecting decades of coordinated scientific effort, habitat restoration, and cross-border cooperation. While the wild population remains fragile, the latest release signals growing confidence that a self-sustaining population may once again take flight across Japan’s wetlands.
