I am at Ueno Station, on my way to Narita airport to catch the Cathay Pacific flight to Perth. I had planned to take the local subway (the Ginza line), to get here, only to find that my station of departure at the hotel, was closed until 5.40 am. (Then how come the train schedule showed its first train departs at 5.18 am? Oh well). So I just took a taxi here.
