The United RCC is a very large lounge that offers showers, snacks, and wifi. Depending on when you'll be in NRT, the SQ SK lounge is also an option, however it's about a 10-15 minute walk from the RCC. The SQ SK lounge is much smaller, but has better food offerings. The SQ SK lounge has 4 PC's connected to the Internet. There are no showers or bathrooms in this lounge, but the bathrooms are right outside of the lounge.
