Just to let everyone know, I got in safe and sound yesterday. Due to a lack of strong headwinds, we made it to Narita and hour earlier than we were supposed to.
Takahashi-san and the driver met me at the airport and we drove to Yokosuka. The traffic wasn't bad, so we got in pretty early (around 5:45).
I will post more later, but Takahashi-san just arrived and its time to go to City Hall for the first time! See you soon!
