Finally I stayed at a hotel my Australian friend runs in Hakuba village for 3 days from on Feb.13rd to 15th.
I just came home.
All her guests were Australians except my Japanese friend and I in this time.
When we reached at the reception, a Australian lady was waiting for us.
She didn't know our reservation but I comfirmed mine twice on a phone before I visited her hotel.
I said to the lady that your lady manager knows our resavation then she phoned to her.
My Australian friend has prepared for the room with quite reasonable room charge.
We paid for only 6000yen for 3 days per a person in this time!
She has a bar in the hotel and every night we mingled with other Australian guests.
She treated on us some beer at the bar and enjoyed harmful and meaningless conversations together.
I could enjoy the atomsphere as if I were in abroad because of her.
