Characteristics A separate window opensReferences

These comprise the waters on the Sea of Okhotsk side of the Shiretoko Peninsula from the peninsula's root to its tip. These waters have a primeval nature, with the coastal ecosystem on the Sea of Okhotsk side being registered as a World Natural Heritage Site. These are the waters where ice floes start to reach shore earliest in the wintertime, and they also are the lowest-latitude waters in the world where ice floes are distributed (Government of Japan, 2004). The ice floes lead to massive increases in ice algae, the high productivity of which means diverse creatures including fish, pinnipeds, birds and others can be seen here. Another of these waters' distinguishing features is the large number of rivers in which wild (not hatchery-bred) salmon (salmon, pink salmon) have been confirmed to swim upstream (Miyakoshi et al., 2012). Breeding of spectacled guillemot and white-tailed eagles has been confirmed here as well (Government of Japan, 2004).
