Don't know, but you might enjoy this article on Japanese art.
I don't know whose it is,
but I can comment that I'd read through a website/series of pages by a "Sandy Beach" on Japanese tickling art some time ago,
in which, he? writes,
more "traditional" Japanese art shows the 'lee with an expression of suffering rather than mirth
(unfortunately, as that often wastes it for me
I much prefer unbearably pleasured laughter or that sort of pleasured expression... so thank you for altering her expression slightly in this example
)
Japanese art (more traditionally) apparently also often involves artist's brushes, sometimes constructions of feathers to imitate birds' wings,
more often tickling private areas
---but those areas aren't shown.
Better to read his site/pages if you're curious.
Very well written, and you'll probably enjoy the drawings...
