Well it depends on what you end up doing.
You can get the Limo Bus ticket with credit card (as long as you're buying the ticket at NRT, HND or TCAT). If you end up deciding to head out to town after you check in and drop your bags off at HND, then I'd recommend withdrawing at least 5000yen in cash. For the most part, train ticket machines only take cash or IC card (Suica, Pasmo... which in turn most likely requires cash to obtain and to deposit value onto). If you wanted beverage from a vending machine, again only cash or IC card. Most stores and eateries accept credit cards, but some don't.
