More importantly - - -

I am sure you know this, but feel like I must make certain. You will NOT be traveling by Nozomi shinkansen from Kyoto to NRT. The shinkansen does not go to NRT. You will be traveling from Kyoto to Tokyo or Shinagawa station and then changing to either the limobus or the Narita Express. Have purchased your tickets for Tokyo-NRT and allowed enough time to arrive at Tokyo, navigate Tokyo station, find and board the N'EX or bus and travel to NRT, while arriving 2.5 to 3 hours before flight time? I ask because the 13:36 Nozomi seems like you are leaving it a bit late. When is your flight out?

As an example, working back from a 5:00 pm departure, you would need to arrive at NRT no later than 2:30 pm, which means getting on the NEX by 1:15 pm, which means arriving at Tokyo by 12:45 or so, which means leaving Kyoto by 10:00 am or earlier.
