I would be interested in conducting a survey of Japanese learners of English to find out what they find difficult about learning English. I'm a university graduate, so no longer part of the university in effect, and am not connected to any research institution, nor any business. I would be an individual acting out of my personal academic interest.
My question is, are there rules or laws that prevent me from doing this? I would have no access to journals or similar, so the most I could do is publish anonymised data on a blog or Reddit or similar. I could collect consent from each participant, but if the survey hadn't been approved by any particular ethics committee would this act be essentially meaningless?
I'd appreciate any advice or input on this matter.
