Very nice hike in snow (late May!), with the guide offered when you ride the nature bus from Morioka Station. I understand Japanese but I guess it is okay if you don't understand, just follow him, but you need to let them know when you board the bus perhaps. They asked and the Taiwanese aren't quite aware of such service. Walked through all the important sights with him.
The dragon eye wasn't quite stunning that day, but the other ponds (or literally the swamps) were very beautiful.
Unluckily the visibility wasn't that high but could still see nearer mountains.
