Narita to Shimbashi with wheelchair

Hi, what is the recommended method of getting from Narita Airport to Shimbashi Station? We will be a party of 3 and my mother is in a wheelchair. We would like to avoid escalators and definitely stairs. We would also prefer to use the train and not take the bus or taxi.

We will be leaving Narita about 7pm Sunday night. I think there is a train direct from Narita to Shimbashi but it does not run on Sundays (or we arrive too late to catch that train).

I've checked Hyperdia and the 1st page of JG search results and would like to ask some questions.

The Narita Express stops at Tokyo Station on Track 1 and the JR Yokosuka Line leaves on Track 2. Are they the same platform?

People have also recommended taking the Skyliner to Nippori. Is the JR Joban Line on the same platform as the Skyliner?

You have direct JR trains to Shimbashi departing NRT T1 at 19:01, 19:35, 20:30, 21:15, and one Keisei/Toei at 23:00. (Based on timetables for this Sunday.)

You can go to "JR" Shimbashi stn without a transfer by regular Rapid that is not limited express N'EX,
but it will be about 30 mins later, use HyperDia again.

In the case of N'EX, it is the opposite side of the same platfome.

Jump to Tokyo and open "Sobu line" map.

In the case of Skyliner, transfering at Nipppori(Keisei-Nippori to "JR" Nippori) stn,
platforms are different place, but there is no problem for wheelchair passengers.

In total, take a Skyliner plan is fastest, but in that time the next train may be stressed, a bit crowded.
The next train to go may be a train of either color that arrives to the left or right of the same platfome,
sometimes those come in at the same time like this, light green one is JR Yamanote line 11 cars,
other side water blue one is JR KeihinTohoku line 10 cars, both are same commuter train of JR.

And in some stns, the elevator may be far side, though, you can find a map of stn easy,
but basically most rail stns in Tokyo are barrier free, also public buses, no worry.

Where is your first destination? (Is it your hotel for that night?)
Which terminal of Narita Airport [NRT] will your plane arrive at?
Have you considered flying into Tokyo Haneda [HND] instead?

On the given conditions,
I would not choose Shimbashi Stations
for the place where you, first in your itinerary, go outside the railway networks.

Are you aware
that JR Sobu Rapid & Yokosuka Line tracks
(, where Narita Express trains and Rapid trains go,)
are deep under the ground
both in Tokyo Station and in Shimbashi Station?

JR Rapid trains, unlike Narita Express,
make a stop at Shimbashi Station
but have no seats which can be reserved.
They go as Local trains beyond Tokyo Station on the Yokosuka Line.

A probable big problem for you is,
because escalators in Shimbashi Station of JR
are not the ones which are initially designed for wheelchairs
and there is only one elevator at each platform,
in a case where the elevator is not available
(due to maintenance works for example),
wheelchair passengers have difficulty in getting to the concourse.

Shimbashi Station of JR is undergoing renewal works.
If you come before the renewal is completed,
your locomotion may be affected by ongoing works.

Also,
the complex of Shimbashi Stations of JR, Toei Subway and Tokyo Metro
is (at least currently) not friendly for wheelchair passengers.

The underground pathways are not completely flat,
i.e. escalators and staircases are on the way.
Only a few among the subway exits (of Toei and Metro)
are equipped with elevators.

The Narita Express stops at Tokyo Station on Track 1 and the JR Yokosuka Line leaves on Track 2. Are they the same platform?

Logically the both trains may use any of the two tracks.

They are Sobu Underground Tracks 1 and 2
beside the same platform among the two,
which lie on the 5th basement of one of the two underground annexes.
(When you say simply Track 1 or 2,
you may well be introduced to the above-ground platform in the main building.)

People have also recommended taking the Skyliner to Nippori.
Is the JR Joban Line on the same platform as the Skyliner?

Skyliner is a service of Keisei, not JR.
(I wonder why you ask about the JR Joban Line;
it does not lead to Shimbashi.)

In Nippori, as long as the elevators are available,
I suppose the locomotion on wheelchairs can be smoother than in Shimbashi.

There is Keisei-JR transfer gate in Nippori and,
if my memory serves me correctly,
the widest interval between the gate machines
is enough for wheelchair passengers.

Thank you all for your replies. I will try and answer some of the questions.

We have already booked flights so can't change to Haneda and I don't think there are direct flights to Haneda from where we are.

We will be arriving at Terminal 2 on June 30th, Sunday, 6pm. We think it will take about an hour to get through immigration and customs, are I think we will get something to eat at the airport before catching a train, that's why I said 7pm.

We are staying in Shimbashi as my mother wants to visit Toranomon Hospital and Shimbashi seemed like a good location to stay (maybe I should have asked here before making booking :)) But from the looks it looks like a good place with lots of restaurants and on the Yamanote Line. I visit Japan regularly and always stay in Shinjuku so wanted to stay somewhere different and on the East Side of Tokyo.

Thank you OcNitz and omotenashi, now I understand Tokyo Station platform (I didn't realise it was Sobu tracks). I think this is the best, easy option for us, even though it may take longer.

My mother can stand/walk *short* distances if needed so will be able to take escalators if needed.

It's strange because hyperdia said JR Joban Line from Nippori to Shimbashi.

Certainly, you can get on the Joban line train (PF/No.3),
bc new track "Ueno-Tokyo line(as nick)" increased fr 4 yrs ago btw Ueno(上野) and Tokyo(東京),
some Joban line trains end stn changed fr Ueno to Shinagawa(品川) overed Shimbashi(新橋).

However, operating number of Joban line trains is smaller
than Yamanote line (PF/No.10) and KeihinTohoku line (PF/No.9), so it depends on the timing.

Strictly speaking, the starting point of Joban line as line name(rail section) is still Nippori(日暮里),
but it is different fr the starting point of the train that actually runs.
In order to avoid the confusion of the passengers,
the stn displays/guides are using also the direct(=through service) trains coming fr "Joban line", no worry.
HyperDia default setting always outs fastest plan as total time,
Joban line trains are a bit faster than Yamanote and KeihinTohoku line's, so the reason is very simple.
