Site details
Site description: Located in the northwestern part from the center of Fukushima Prefecture, the lake is at 514 m height above sea level, with perimeters of 56 km and 103.3 km2 in area. Due to inflow of strongly acidic groundwater and rivers, the lake shows acidification, with low Chemical Oxygen Demand (COD) in the water and high degree of transparency. The surrounding wetlands include the one with the government designated Natural Monument Akaiyachishoya helophyte community mainly composed of Sphagnum.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
