Japan Eases Threat Status for Red-Crowned Crane and Crested Ibis in Red List Update

Decades of protection alongside reintroduction underpin the ministry’s five-year assessment citing measurable population gains.

Overview

  • The Environment Ministry published a revised Red List on March 17 covering birds, reptiles and amphibians after its periodic review.
  • The red-crowned crane was reclassified from endangered categories to Near Threatened following recovery to about 1,200 adults, a species that had fallen to 33 individuals in 1952.
  • The crested ibis moved from the highest-risk 1A class to 1B, with an estimated 576 individuals in the wild as of the end of 2024 following releases on Sado Island.
  • The Amami woodcock’s risk ranking also improved, with reporting citing invasive mongoose eradication and forest recovery as factors in its rebound.
  • Officials highlight that continued habitat protection and monitoring remain necessary even as 48 species, including the dunlin and the Japanese pond turtle, were newly added to endangered categories.
