The site was identified as internationally important for bird conservation in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Japanese Woodpigeon Columba janthina	LC	resident (2003)	present	A2
Ryukyu Green-pigeon Treron permagnus	LC	resident (2003)	present	A2
Ijima's Leaf-warbler Phylloscopus ijimae	VU	breeding (2003)	present	A1, A2
Izu Thrush Turdus celaenops	VU	resident (2003)	present	A1, A2
Ryukyu Robin Larvivora komadori	NT	resident (2003)	present	A2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	likely in long term (>4 years)	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	Unknown	Unknown	low

Year	Protected Area	Designation (management category)	% coverage of IBA
