Then Taxi till near the trail: The point till where the Taxi/Van or Mini Bus will take you to where the walking trails will start. I think the charges were 700 or 900 Yens/Adult. Lesser for kids.

 If you are more than 9 members, while coming back, take only 9 tickets which is the max capacity of the vans (A Kids ticket can be exempted). We were told this later though :)

A short walk (100 mtrs) and the exact trail starting point
From the Taxi stop, you walk to this point from where the trails start. This is also the point from where the taxi tickets can be bought. Taxi is the only option till 10th of October. After this time, it is opened to normal vehicles and Even private cars can travel to this point. In case of only taxis,  last taxi taking back to your car park is at 17:15. There is a small refreshment area here.

Which Trail of Kids/Others:
For kids : Looks for the left side mark when you start your trail. There are three such markers. The destination would be around here : https://goo.gl/maps/pzEaj7Hr5vm.  Following trail is easy. It is 3.3. Kms one side and starts with a decline till you start walking on wooden pathways. Only while coming back kids will realize that there is an ascent. Take breaks in that case. Otherwise they will enjoy the route. Also there are bells on the way to notify beers the human presence. Do that and kids will have something to enjoy. Also just before 0.5 to 0.7 km there is a sitting benches in a corner where you can have your snack break.

As soon as you complete this 3.3 kms, there is an open camping area, place to live (like Dorm log houses which required prior reservations). There is a small caffe and food place too here for refreshment. Toilets too. From here you can explore more go in the direction of lake, which can take some time. Take a call based on how much time you have more to return back.There are longer trails of 7 kms from there and deeper for several kms. Would suggest to explore only if you are staying there.

Onsen while coming back:
If you area fan of Onsen, the locals swear by this onsen. Its a beautiful rotenburo included too surrounded by small mountain styled trees overlooking the mountain ranges. Small flowers too as in the name :)
