Its not that bad, at least you will be out of the airport for a change and get some fresh air. Here I found something for you in the web:

One of the delightful things to do when visiting Naritasan is to stroll around the temple town. The main pathway (Omote-sando) runs through from JR Narita station to Naritasan. There are many shops along this path.

The main street runs from the station to the the entrance gate of Naritasan. There are quite a few old stores with more than 100 years of history, many Chinese medicine stores built of Dozo(warehouse) style, and large wooden Three-story hotels. There are unexpected surprises not only on the main street but also down the narrow side streets.
Another charm of temple town are the local products like Sweet jelly of azuki beans (yokan), Japanese pickles (tsukemono), fish boiled in soy sauce (tsukudani) or local rice-wine (sake) and strolling along the main street eating hand made rice crackers ( teyaki-senbei) or eating broiled eel in a restaurant.

Being an international city Narita, there are many visitors walking along the main street and also some restaurants and noodleshops are almost used exclusively by overseas visitors.
