It is no problem if yr flight lands in midnight.
In that section is operating everyday fr early morning to late night.
http://www.hyperdia.com/en/Both trains are using commuter cars, no seat booking.
BC all lines are same rail company "Keikyu", so no need ticket gate out at the transfer stns,
and only one paper ticket(or IC card ticket "PASMO"), you can purchase it at HND.
If you can catch the bus time in day time,
is cheapest(280Y/cash, 278Y/IC), shortest and no transfering,
but need over 10 min walk after get off bus stop.(some stairs up and down)
https://goo.gl/maps/eioYg9G4nBw(big note) Google bus route result is wrong.
That section bus operate company is not "Limo bus", "Keikyu" for (空51) Kawasaki stn is.
Bus stops are fr 羽田空港国際線ターミナル(HND int'l terminal)
to 7th stop 大師橋下(Daishi-bashi shita/means "under the Daishi bridge)
空51 is just a bus route number, this 空 is short of airport = 羽田空港(Haneda kuukou)

https://pbs.twimg.com/media/DSGuxZAVAAA-uG-.jpg:largeStn entrance is a bit difficult to find now by big construction to switch the track to the underground.
Look for yellow guiding blocks for blind persons.
https://pbs.twimg.com/media/DZrAhsqV4AEaYFo.png:large3rd way is just you can do, but no recommend.
Take a same bus fr HND and get off 6th bus stop 羽田特別出張所,
then wait near conveni "Familymart", and catch a driver to hitchhike.
Most cars cross the bridge and proceed until Sangyodoro stn, very easy way.
https://goo.gl/maps/2GTdoNe2k7K2Often larger trucks will stopping on the road. (like shown in this streetview)
It will be almost never refused, bc very short distance.
There is a another same company bus that crosses the bridge fr this bus stop,
but because there are only two(morning and evening) in one day, so this is not recommended,
bus fare also a bit exceeds the train fare by two buses. (not so big different)
Taxi fare is around 1800Y/20min fr airport, if not solo
or late night(up to around 2200Y/after 22:00), not so expensive.
(extra info)
The bridge name Daishi fr Kawasaki Daishi. (a big temple, very famous)
