Population justification: The global population is estimates to number 150-584 individuals (Ikehara et al. 1991 in BirdLife International 2001), roughly equating to 100-390 mature individuals, while the population is Japan has been estimated at < c.100 breeding pairs (Brazil 2009).
Trend justification: This species is suspected to be undergoing a moderate decline as a result of the on-going clearance of old-growth forests.
