Help for my University Report, searching participents for my survey about sustainibility in japanese wintersportstourism

Hello everyone,

I have just moved to Osaka and still have to write my final report for my German university. I am studying sports science at the German Sport University Cologne.

My professor recommended that I write about Japanese sports, so I decided to research winter sports. My report is about the perception of tourists in Japanese winter sports tourism, and I will need some participants for the survey (minimum 200).

Do you have any idea how I can find people in Osaka who will fill out the online survey?

Any help would be much appreciated. Thank you in advance.
