Inclement weather at destination airport during layover in a foreign country

As many of you North Americans know, there is an upcoming winter storm hitting the Northeast soon (at time of writing). I am about to take a flight from Shanghai, China back to New Jersey, with a layover in Narita, Japan.

If I arrive in Narita and the second leg of my flight is delayed (possibly to the following day), will I be permitted to exit the airport? What would be the standard procedure for the airline? (In addition, what would happen if I had to stay overnight?)

Additional information:

I'm a Chinese citizen, leaving from Pudong International Airport, stopping at Narita, and finally arriving at Newark International. The first leg (Shanghai-Narita) is operated by All Nippon Airways, and the second leg (Narita-Newark) is operated by United Airlines. I am also a minor (under 18), but not considered as an unaccompanied minor, at least by United.

Thanks in advance!

What to do when you have a layover in another country?

For virtually all international airports, as long as you are on a single itinerary with your bags booked through, you will stay in the transit area and do not need to clear immigration or Customs.

Can I leave the airport on a layover in another country?

Yes, you can leave the airport during a layover while traveling internationally! However, it is never easy as compared to the domestic layover. For instance, the country you're in could require a visa even to visit.

What do you mean by layover in flights?

A layover is a broad term that means any connection between flights. This could include a stop as short as 30 minutes (depending upon the airport) or as long as four hours (or up to 23 hours and 59 minutes on international flights). Airline crew use this term, slightly differently.
