vintage Japan hand painted moriage china, mini oil lamp, lighter base or vase

Unmarked Japan hand painted china vase shape about 3 3/4" tall, mid 20th century. This looks as though it might have been a mini lamp, or maybe a cigarette lighter? It's shaped as though it might have held some sort of fitting at the top.

It's very clean inside and out, and was obviously never used to hold lamp oil. No chips, cracks or staining, but this does have a few spots of wear to the paint.
