train to osaka to tokyo airport

I am staying in Osaka and need to be in Tokyo airport at 9am. Can I leave Osaka early in the morning and get to Tokyo airport for my flight? I can't find out whether the trains stop at the airport. Otherwise, I will go to Tokyo the night before. Many thanks for your help, Lorna

There's no direct trains connecting Osaka and Narita Airport. If you want to be at the airport, you need to leave Osaka the night before. From Osaka, go to Shin-Osaka station and take the shinkansen to either Shinagawa or Tokyo station. Then, switch to Narita Express. The whole journey takes 4 hrs 30 min when everything goes smoothly.

You better stay in Tokyo from the night before unless you fly.

First train connection, on the assumption that you have a JR Pass:
Shin-Osaka 6:08--(Shinkansen Hikari)--9:02 Shinagawa 9:50--(Narita Express)--10:57 Narita Airport

First flight:
Osaka Itami(ITM) 7:55--(ANA, or NH2176)--9:05 Narita Airport(NRT)
