I have tried to give you as many handy hints as may help you from getting completely lost in your first few weeks. It can take a while to get used to Japan so please hang on in there. Most people love it for a while, then hate it, and then love it again, so it can be a bit like a torrid love affair at first before things settle down. Not everyone can take Japan ompletely, but having lived in four countries, I can tell you that every place has its pluses and minuses, and in the end it is better to try to live by maximising the former and minimising the latter. I wish you all the very best for your experience in Japan, and Ganbatte Ne!
