How easy is it to use Uber in Narita? I will be staying in Narita Excel Hotel Tokyu, which is about 4km from the Narita station. Their shuttle to/from Narita station is not very frequent, so I am wondering if it would be a good option to use Uber. Thanks!
Btw, I have US$20 in credit from some sign-up promotions earlier. Can I use it in Japan?
Uber operates primarily in central Tokyo. Unless a driver carries a passenger to NRT and needs to pick up a passenger, or a driver turns on Uber while at NRT, I wouldn't count on finding a car randomly.
In your case would just as soon use a normal taxi; it should cost about 1,900-2,000 JPY.
