The arrival of migratory birds in Japan is celebrated each winter, with some of the world’s largest over-wintering sites for waterfowl spread across that island nation. Japan is the home to 90% of the overwintering Hooded Cranes of the world, and they are regarded (and often referred to as) `National Treasures’.
In 2010-11 we saw a near panic among officials when 5 Hooded Cranes Test Positive For H5N1 in Izumi, in the spring of 2014 - just a couple of months after emerging in South Korea - the H5N8 virus arrived in Japan for the first time, carried in by migratory birds.
During the fall and winter of 2014-15, Japan's poultry industry was hit repeatedly by HPAI H5N8, at about the same time the virus was encroaching on Europe and spreading in North America (see Japan: HPAI H5 Confirmed In Saga Prefecture).
Except for scattered reports from South Korea and China - to everyone's surprise (see PNAS: The Enigma Of Disappearing HPAI H5 In North American Migratory Waterfowl) - H5N8 was pretty much a `no show' last winter.
This year, however, H5N8 is back with a vengeance in Europe. And so other areas (including North America & Japan) have to be alert for its return as well.
When you add in the detection of HPAI H5N6 in bird feces last week in Korea (a migratory bird stop off point for many species headed for Japan) the stakes get even higher.Today Japanese media is carrying multiple reports of dead birds collected in two Japanese Prefectures (Akita and Hokkaido) that have reportedly tested positive in the field (subtype not identified), that are being further examined as to subtype and pathogenicity.
It may take several days before we get a definitive answer.

The most obvious suspects are H5N1, H5N8, or possibly H5N6. In any event, the bird flu season continues which only just sparked to life a couple of weeks ago, continues to ramp up around the globe.
