The walls of Kamesei's main hallway have gotten pretty beat up (due in no small part to our rambunctious sons). Today, we had a pro come in and take off the applied wall and put on wallpaper. He told me that Western Wallpaper was applied with the edges overlapping. In Japan, though, that's considered a fire hazzard, to the paper here is designed to be applied with the edges lined up with each other. Even in wallpaper, East and West differ!
