Arriving June 24th Leaving July 1st

Hello there,

Would appreciate some guidance on how to get back to Narita once my 7-day pass expires.
As the subject reads, I arrive to Narita on June 24th. I purchased the 7-day pass, which will cover me until June 30. My question is, are there 1-day passes that I can purchase? And where?
Thanks so much.

Gabby
