My guide book says a taxi from Narita could cost $200!!! I've been several times and have always taken the train which is cheaper and quite convenient...and if you're staying at a hostel then a taxi seems like a budget breaker!
Tokyo is easy to get around in. Get a good bilingual map before you leave (should be easy to find in Los Angeles)....the directions from the nearest subway stop to the hostel are probably posted on their website, if not, send them an email and ask.......it's easy enough to take a train from the airport to a station where you can switch to the subway and then get off at the closest stop to your hostel....and then walk a few blocks, just make sure you're taking a suitcase with wheels (edit; "How to get there - Ace Inn Shinjuku Hostel; The nearest station is 'Akebono-bashi' by Toei Shinjuku line. Take A3 exit, and come to left way. You'll see us in 30 seconds"). There's enough signage in english to navigate the subways although sometimes you'll have to look for it.
And if you need help, somebody will help you. The Japanese are very kind to visitors.
