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 Murrelet Synthliboramphus wumizusume	VU	breeding (2003)	present	A1

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%)	slow decline (1–10% over 3 gener­ations)	medium

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
1968	Notohanto	国定公園 (V)	100
1973	Nanatsujima	国指定鳥獣保護区 (IV)	100
1974	Sotoura kaga	沿岸水産資源開発区域 (VI)	22
2013	Common fishery right area(Ishikawa)	共同漁業権区域 (VI)	9
