We got a problem with Airbnb payment method, then my trip was canceled 1 week before the trip, and I did not check my email, I had not known my destination until arrived Japan. After that I messaged to Aya about the problem said to her I have no place to stay T^T (she was in Kansai at that time, because she thought that i had already canceled my stay). When she knew that, she had to opened her house for us at midnight. Her mother Yoko-san drove from Yokohama to Kokujunji to welcomed us. What they made for us, I am so appreciated.
