Exterior
Surface, Outside
noun
The outside face to something is the exterior of that thing.
がいめん
そとづら
This is a jukugo word, which usually means on'yomi readings from the kanji. This reading is usually for building exteriors and outside surfaces. The other reading そとづら is used when a person's personality comes to the surface and is a bit of an exception, so you'll probably see it less often. Just keep those differences in mind!
