Question: are there swans in japan?
Answer: Swans arrive in Japan from mid-October onwards, and up to 32,000 Whooper Swans and 31,000 Bewick's Swans have been recorded in mid-winter in the late 1990s. This is more than 50% of the East Asian populations of these two species. In addition, 150 feral Mute Swans (Cygnus olor) reside in Japan throughout the year.
