Come take a look
Well you can't come to Kushiro and not take a drive out to see the Red Crested Cranes between Kushiro and Tsurui. The best time to see them is winter, especially if it has snowed recently. Then you can get really great 'winter wonderland' snaps of the cranes frolicking in the snow. Also, there's usually blue skies in Winter. Summer is often a bit dull with all the fog about. I find that there's often a lot of cranes at about 3pm, but some people tell me that they're there in the morning too. Take the road to Tsurui and you'll see the signs about 20kms down the road.
