Advise on Working as a front desk employee in a Japanese hotel.

Hello everyone, I wanted to ask if someone had any experience of working at any hotel in japan full time and how was it? I am currently learning Japanese language in my home country and might get the opportunity to work at a hotel in Japan as a front desk employee, chances are pretty high. I have read a lot of negative reviews about japanese work culture and truthfully I'm a little bit worried. can you tell me what are the working hours? is it 8-9 or more than that? what are the working days? do you get 2 week offs or 1 or non at all? im pretty serious about getting the job. and also what are the points that i should look out for before accepting any offer? and any other advice you can provide that would be useful. frankly im not afraid to work hard but borderline labour law abuse would be a no for me. any suggestion would be greatly appreciated.
