Day use Narita
 

Any recommendation for day use hotel in or near narita land side? Need it from 8 am to 2pm? What site to book from?

Closest from the terminal is nine hours Capsule Hotel (click "English" on the top of the web page for English website) by Terminal 2. Located at the basement of Terminal 2 parking facility. Check-in for day use starts at 9 a.m., if that will work for you.

Other hotels with day use plan will be outside of the airport, where you will easily waste one hour or more on waiting for shuttle service and transport to/from the airport.

I did check that but it says capsules can't be used from 10 to 12 due to cleaning.
