Late Arrival and Early Departure at Haneda

wld anyone be able to advice what's the cheapest/fastest way into Tokyo/Ginza fr Haneda Airport in Dec 2010?

My flight into Haneda lands 2335 hr and leaves 0625. Any late or early trains?
Tried Hyperdia - but not sure I u'stand it.

I heard that Taxi is really expensive in Tokyo.

Thank you for any advice that might help!

The train and bus timetable for access to/from Haneda Airport beyond October 2010 have not been published yet.

The train, monorail and bus companies are currently studying how to deal with the late night and early morning flights. Personally, I think it is unlikely that train and monorail service will be expanded considerably in the evening and mornings, but there might be more additional late buses. Taxi is expensive.

I recommend to wait until October and visit this site again. By then, the new timetables should be published.
