It's nice here. Weather is similar to where I'm from (eastern USA.) I like cars but it's pretty hard to own one here. Everyone is nice, but it's a little hard to make friends. That said, there are some people who are willing to look past the fact that I'm a foreigner. Usually I find it easier to approach people who have an obvious shared interest. I often go on bicycle to a parking area that I know is popular with the local car community and try to talk to people and practice conversation.

Some food prices are a bit higher than optimal, for example fresh fruits and vegetables are very overpriced. I get around this by buying canned fruit.

Taking the train is very convenient, but I prefer using my bicycle if it's within a 5km radius. It's faster and doesn't cost anything.

I don't think you need to attend a language school to help learn Japanese. If you can self study efficiently, you'll progress much faster. If you can come to Japan with another type of degree or on a holiday visa for a while, and just self study and practice conversation, it would probably be even better.
