>>2341876陰毛 means pubic hair and is in general the tag for this.
In japanese porn is 剛毛 pretty much the japanese word/slang for bush or thick pubic hair it seems. But I found on Pixiv only disgusting pubes in a ugly way. If you google エロ 剛毛 (first word is for ero) then you get some nice japanese bushes. But mostly real porn. Or google エロ 陰毛.
