Oirase Stream hike - where to start

Hi,

i'll be visiting Towadako at the end of October for koyo. My plan is, to take the 10:00 JR bus from Hachinohe West station; drop off at one of the bus stops in the Oirase stream area, and hike to Towakado-Yasumiya. May I know which is the best spot to start hiking? I would be staying for a night in Towadako.

I'm also thinking of taking the sightseeing cruise on Towadako, but the timing is tricky, and i'm also trying to avoid overlapping some routes.

The following day, my plan is to take the 8:40 JR bus to Aomori, to visit Hirosaki. If needs be, this could be given up. But because of the timing of the JR buses, it might mean i would have ample time in the area the following day. is it worth? Or should my start and end point be a total swap?

BTW, what is the difference between Yasumiya and Yasuya? I came across these names and am unsure if they are both referring to the same area in Towadako.

Thank you very much.

When I searched the route on Google Map, it takes more than 3 hours to walk from Oirase Stream（奥入瀬渓流） to Yasumiya（休屋）.
If you walk to Nenokuchi（子ノ口）, it takes about 1 hour and 30 minutes from Oirase Stream, so I think it's better to walk this way.
There is a sightseeing boat from Nenokuchi to Yasumiya. chrome-http://www.toutetsu.co.jp/ship/leaflet/lake_towada_cruise_english.pdf

If you take a bus to Aomori, you may also see the autumn leaves on the Jogakura Bridge.
