I have a question about tagging Japanese and Chinese umbrellas.
In this example post #833856 one would assume a Japanese umbrella while in this example post #520794 one would assume a Chinese umbrella.
Would the term paper_umbrella be better? It is very likely regardless of whether it is Chinese or Japanese it will be made of paper (and not silk as the very old Chinese ones were).
Most old Asian umbrellas generally look like this. Without more elaborate decorations like the OP examples, it'd be hard to tell their... nationality (e.g. Korean ones )
paper_umbrella is a good suggestion, but as Scarlet 200% said there could also be silk version. I don't know if we have any image of that type. Just to be safe, how's about a catch all term like asian_umbrella?
