I can’t find anything corroborating this (most sources I checked stated ~ski just meant ‘comes from ~’ in the name kinda, so you may want to be careful about what you “learn”.
Examples: https://theskilesson.com/why-do-polish-names-end-in-ski-discover-the-fascinating-reason-behind-it/ states it may have helped popularize it a bit (presumably by having the place whence they came in the name?) but I don’t think the above poster’s statement is actually true here considering the link and several others I checked.
I’ve even living in Japan for almost a decade (probably closer if you count times I visited for months before living here). If you have specific questions, I’m happy to answer them.
