Getting there:

There is a bus that runs from Hirosaki station to Shirakami-sanchi but it is very infrequent. There is also an infrequently running trainline that goes directly along the coastline (is stunning) but train staiton is a bit out of the way in connection to the site. A car is recommended so that you can drive along the coastline and not have to worry about bus/train connections. Park at the omiyage shop called Kyororo, there is a large paid carpark that will give you access.  

Route/Trail notes:

At the back of the carpark, you will see a disused road. This will take you along a big lake, heading towards the blue lake. Flat path with no difficulty.

From blue lake, go up to the stairs and look for signs pointing towards Takitsubo滝壺, I personally think that this is the more beautiful lake despite the blue lake getting all the fame. A walk past this lake will take you on a nice loop back to the car park.

Shirakami-sanchi is massive and there are a lot of options to explore branching paths and heading up mountains. Just be prepared for bears as there is apparently a heck of a lot swarmin' the place.
