Hi Everyone !
I'm a French/Japanese guy, in architect studies, and I just want to inform you that we have a big japanese House "Pension AYK" to welcome students or travelers in Osaka... It's a very big house, with a zen garden, internet connection, and all others facilities... Near the train station... So it's very great for your trip in Japan..
