Beginner camera?

Hello! I recently moved to Japan to study and during in my free time I like to visit temples, shrines and the other beautiful places I can find around here. I love taking photos to keep as memory, but unfortunately my phone is pretty cheap and it's camera is quite bad. Taking photos is something I enjoy a lot, expecially now that I have the opportunity to experience this beautiful country, but I'm not satisfied anymore with the quality that I get from my phone and so I started thinking about buying a camera and getting a bit more into this hobby. I tried taking a look at a japanese second hand websites and I notices that people are selling a lot of different Nikon cameras (some are still quite too expensive for me, but some are at an ok price), but I have no knowledge in photography and I have no idea which ones would be best for someone like me with no experience. So which model would you suggest me to buy?
