As you can see from my username - exJerseygirl here. I grew up in Jersey and still have lots of friends there. I lived in South Jersey, which as some here have pointed out is a completely different state from North Jersey. There are lots of people who say Jersey is actually 3 states: South, Central, and North.
In any case, here are some things that you should know about Jersey:
- It is the butt of many, many jokes, not the least of which about it being the armpit of the nation squished in between Philadelphia and NYC. There are areas that smell funny, but they are generally limited to the area around Newark airport, the Delaware Memorial Bridge, and Camden.
- Jersey tomatoes, Jersey corn, and Jersey blueberries are unequaled in terms of their awesomeness.
- Jersey is EXPENSIVE. I see you've been living in Japan, so the cost of living in Jersey might not be quite as shocking, but to live in the nice areas it's going to cost a lot relative to a lot of other areas in the States. Last I knew, Jersey has the highest population density of any state in the Union, which means more people, cars, houses, schools, etc crammed into its borders. Property taxes are among the highest in the country, as is car insurance.
- Transit links are primarily to get people to/from the big cities not actually located in Jersey - Philly and NYC. Transit links in the state are not as strong. If you're trying to commute from one place to another within Jersey - try and be on the opposite side of your communting destination from the city (i.e. live west of your office town if your city is NYC so you've got the morning and evening commutes in the right direction).
- Chose now: Giants or Jets (since you'll be in North Jersey, the Eagles are not an option)
and finally..
- People in Jersey don't got to the beach, they go to "the Shore." Usually they go "down the Shore" But only the Jersey Shore; if they go to Maryland or the Carolinas, then they go to the beach.
Also - one last note: if you are trying to live in Jersey without a car.... well, move to Manhattan. 99.9% of Jersey is like 99.9% of the US - built for driving, not walking/commuting.
