As of today, out of season, returns ~November. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Each winter, endangered red-crowned cranes (tancho, Grus japonensis) concentrate in the Kushiro-Tsurui marshes of eastern Hokkaido.
At sunrise many birds depart riverside roosts such as Otowa Bridge for feeding grounds, creating dramatic silhouette and flight displays against the winter light.
This is a seasonal, weather-sensitive wildlife viewing opportunity.
