Second hand car budget

Hello I am new to here but I have just moved back to japan to study a masters. I am very lucky to be on a scholarship that provides me with a stipend of 140,000 yen a month. I understand this is not a lot at all but because i live in the countryside, my rent is around 5000-7000 yen a month. As a result though, I live deep in the countryside and so almost definitely need a car. I have a valid international driving license and I won’t have to pay for a car parking space. I have some savings as well on top of my monthly stipend. If I went with the most basic car, such as Kei car, do you think I would be able to afford with my stipend? Do you recommend anywhere in particular where I could buy a second hand car? Thank you for any advice!
