Job title differs from actual job – too risky?

Hi everyone. Currently searching for a job as my language school graduation is nearing and I'm confused about this potential job i was introduced to.

An acquaintance of mine works part-time at the beauty salon and she invited me to work for them(doing beauty services as well). I briefly spoke with the boss and she said they can do all the paperwork and sponsor a visa for me to work for them full-time.

But obviously there's no visa for beauty services so i assume they will apply for me not as a salon master but as something else, like SNS manager etc but the actual job will be providing a beauty service.

I'm kind of desperate because my job search is not going well… but i'm also very concerned about the risk i might be taking if i proceed with them.

So my question is, how risky is this situation and what are potential consequences?

Some more details: the salon is new so they actually don't have any experience giving visa to anyone(yet?). I haven't spoken to the owner in details, so idk what employment type they offer and basically any details outside of the job itself and visa support that they offer. I also have a bachelor's degree in marketing/PR

If not for visa concerns, it's a great job and I'm really interested.

I hope to be in Japan for a long time so i don't want any problems, i guess it's better not to take the risk but i'd like to hear if anyone has anything to say. Maybe you or someone you know had a similar experience
