Narita Skyaccess to Higashi-Nihombashi

I will be arriving at Narita T1 on a weekday at 4pm. I have the following queries:-
1) I plan to take the Narita SkyAccess to Higashi-Nihombashi Station. What signboards should I follow for Narita SkyAccess when I reached the train station at T1? I will be using SUICA card.
2) Will there still be any Narita SkyAccess train to Higashi-Nihombashi Station at about 5pm on a weekday?
3) Once I am aboard the Narita SkyAccess train, will it take me direct to Higashi-Nihombashi Station without having to change trains?

I appreciate assistance on the above queries as it is my 1st time travelling to Tokyo. Thank You

Hyperdia is your friend.

1) follow the railway looking signs.

Narita T1 has good signage in English these days. The trains are downstairs, this video shows how to get there https://www.youtube.com/watch?v=irKvrnigZ0Y The Keisei Access Express seems to take you where you want to go. http://www.keisei.co.jp/keisei/tetudou/skyliner/us/nrt_access/index.ph...

1)
See the NRT web, floor map.
https://www.narita-airport.jp/en/sitemap

That route trains dep fr "Keisei", ask at Blue counter if still wondering.

(NOT "JR", Red counter)

2)
No direct train in that time, operating hours already overed. (as present timetable, which date?)
https://goo.gl/bhwJyg
(Weekday last direct train is dep at 16:04 fo Keikyu Kurihama.)

3)
No, need one transfering at Aoto or Keisei-Takasago stn.
http://www.keisei.co.jp/keisei/tetudou/skyliner/us/index.php
No need ticket gate out at transfering stn, 2nd train also using same platform very easy.

Higashi-Nihombashi stn is not "Keisei" section but no worry, through train service.
After Oshiage stn will be "Toei" Asakusa line.
https://en.wikipedia.org/wiki/Toei_Asakusa_Line

And, it is crowded by evening rush when you arrive Higashi-Nihombashi stn, (not so crowded fr NRT)
so 2nd train you'd better sit down near the door of "Left".
https://youtu.be/8U-I3Gq6Jug (this not in evening rush)

Paying by Suica also possible, just touching twice, NRT and Higashi-Nihombashi stn.
ReCharge and balance(left of SF/Charge) check can be done at ticket vending machines of NRT (Keisei's).
Suica balance(left of SF/Charge) check is free. (printing uing history of last 20 also free)

(note)
Keisei doesn't sale "Suica", Suica is "JR-East" card.
Keisei is one of "PASMO" card saler, just using possible even "Suica" card.

Have you cheeked a route map?
http://www.keisei.co.jp/keisei/tetudou/railmap/railmap.pdf

The Narita SKY ACCESS Line does not lead to Toei Subway Higashi-Nihombashi Station (A-15), which is at the lower left of the map.
This line is one of the two Keisei lines to connect Narita Airport Terminal 1 Station (KS42) (at the upper right) and Takasago Station (KS10).
The other is the Keisei Main Line.

Please distinguish the confusingly named "Narita SKY ACCESS" Line and "Access Express" train service.
The routes of the Access Express trains, which are shown in orange in the map, is NOT equal to the Narita SKY ACCESS Line.

Currently the Access Express trains departing later than 16:30 (4:30 p.m.) on weekdays from NRT T1 run for Ueno Station (KS01), not in the direction of Higashi-Nihombashi Station (A-15).

At Takasago Station (KS10) or the next Aoto Station (KS09), you can get off your first train then catch a Keisei-Toei through train.
(You choose any train which is NOT bound for Ueno.)
There you can change trains quickly; the two trains would use either the one same track or the two tracks beside the one same platform.
Every Keisei-Toei through train makes a stop at Higashi-Nihombashi Station.

What signboards should I follow for Narita Sky Access when I reached the train station at T1?

Keisei and JR-East each have stations in NRT Terminals 1 and 2.
In Narita Airport Terminal 1 Station of Keisei, you just follow signboards for the Narita SKY ACCESS Line.
There you pass through only the entrance gate; the intermediate gate is for the Keisei Main Line.

Thanks @Omotenashi. Keisei really don't do themselves any favours with their naming system. I tried to do a very similar trip to this in reverse last year and go so confused I ended up going via Ueno rather than take a chance.

The best way to deal with the weird train names is to ignore them; they are just there for marketing and not at all relevant. All you need is the departure time and destination, which you can get from Hyperdia et al. Then read the departure track from the station signboards, and you're good.

Oh, lots of response.

Just use Keisei's Transfer Planner & Fare Calculation tool.
http://keisei.ekitan.com/naritaacs-i/N2?osb=1

It is powered by Ekitan, not by a notorious Hyperdia. Most Japanese do not rely on Hyperdia, because of its surprising results for locals.

Do you suggest to transfer a NEX to a Hikari at Tokyo station from B5F at the west side to the ground floor at the east for a traveler with the luggage? I know most commenters in TripAdvisor are not. They insist to do the transfer at Shinagawa. Most of them appear to use HyperDia in their hands, but not recommend to use it. I shouted at there once. HyperDia has succeeded only in localization but failed in the Japanese market. This means almost no feedbacks from a majority of users. Jorudan has been a winner in train transfers. Navitime in the bus ones. With this situation, GoogleMaps adopts Jorudan. GoogleMaps and Jorudan start to involve buses and the others. No rivals anymore. GoogleMaps is a tool from A to B, from the beginning. No need to identify station names. Jorudan also tries to adopt such functions. Recently, Jorudan released the Rail Pass Search tools on their global site. Currently, I could recommend three tools below.

1. Google Flights
https://www.google.com/flights/
Select the most reasonable flights. A difference in flight fares usually goes over a slight gain in train passes.

2. Google Maps
https://www.google.com/maps/dir/
Estimate the total costs. Prepare the followings with a text editor, and copy and paste one by one.

https://www.google.com/maps/dir/(Entry Airport)/(1st Hotel)/
https://www.google.com/maps/dir/(1st Hotel)/(1st Site)/
:
https://www.google.com/maps/dir/(Last Site)/(Last Hotel)/
https://www.google.com/maps/dir/(Last Hotel)/(Departing Airport)/

Such as
https://www.google.com/maps/dir/Narita airport terminal 1 Japan/Apa Hotel Higashi Nihon Bashi Mae Japan/
https://www.google.com/maps/dir/Apa Hotel Higashi Nihon Bashi Mae Japan/Meiji Jingu Japan/
I usually use Japan for sure. Putting other location names make it more complete; Tokyo, Chiyoda, Chuo.... The strings with spaces do work, but plus signs to deceive this forum, as in below.
https://www.google.com/maps/dir/Narita+airport+terminal+1+Japan/Apa+Ho...
https://www.google.com/maps/dir/Apa+Hotel+Higashi+Nihon+Bashi+Mae+Japa...

3. Japan Transit Planner
https://world.jorudan.co.jp/mln/en/japan-rail-pass/
Compare the total cost with a list of pass prices. In the case that the cost exceeds the pass price, try to find other solutions with this and others. The top two sites in Japan are still only in Japanese.
https://www.jorudan.co.jp/
https://www.navitime.co.jp/

You may check the Japanese market by the two major search engines in Japan. I believe Google: Yahoo is around 7: 3. HyperDia appears on the second page in the searches below, meaning not in the top 10. Now it seems Yahoo is getting more popular than Navitime, but the top is still Jorudan.
https://www.google.co.jp/search?q=�æ‚芷‚¦ˆÄ“à
https://search.yahoo.co.jp/search?p=�æ‚芷‚¦ˆÄ“à

In the trend search, Yahoo goes over Jorudan. But I suspect that table-based planner is already out of date. Most people already switch to use map-based one; GoogleMaps.
https://trends.google.co.jp/trends/explore?q=�æ‚芷‚¦ˆÄ“à

One more try...

https://www.google.co.jp/search?q="�æ‚芷‚¦ˆÄ“à"

Do you suggest to transfer a NEX to a Hikari at Tokyo station from B5F at the west side to the ground floor at the east for a traveler with the luggage?

I do not suggest anything, but I note that criticising Hyperdia for suggesting to make the NEX-Shinkansen transfer at Tokyo and then promoting Jorudan is hypocritical because Jorudan suggests the same thing.

It may be true that Hyperdia is not popular in Japan for whatever reason, but certainly not because its results are inaccurate.

I could not connect to the mentioned site... What happened?
http://forum.japan-rail-pass.com/discussion/1862/looking-for-itinerary...

Maybe, just newer ones are superior to the old one.

Anyway, it is not by one particular case. Since I l had known of HyperDia, I have tried to use it to go along with the English speaking community. But, I have found many funny results from a local point of view, "Nanja Korya?", and then stopped continuing to use it. I suspect many Japanese did the same. There would be no fault-free system in the world, but at least I feel Jorudan is better than HyperDia. That would be an answer in the market. Google might have followed it. GoogleMaps itself is not created by them. Rome2rio is the original. But maybe no one knows even their name. Now, I totally rery on GoogleMaps. Rarely, I use Jorudan for a cross-check. Never, HyperDia.

You could recommend HyperDia. This might be a kind of religeon. Many refuse to change the tool they are familiar to, at TripAdvisor, Fodor, Japan-Rail-Pass and here. But, for me, it looks like a retailer selling a dead stock to a customer. It might come from a tendency that Japanese like to use a newer one in every area.

Of course everyone is free to use and recommend whatever they want, but if you're going to accuse a particular service of providing inaccurate results (as several people regularly do here), the least you can do is have solid evidence to back it up.

There are many reasons to make the transfer at Tokyo. First on to the shinkansen car so you can place large luggage at rear of seating area. First on to the shinkansen if using non reserved ticket. Etc.

Shinagawa is a smaller walk for easier transfer with luggage, but you miss out on the above benefits. But both have their pros and cons.

Just because one is better in your mind doesn't make it the right choice for others.

You are so fluent, aren't you? Try to do the same. Look at your first reply in this thread. Is it a kind reply to the poster?

As I said, it is an answer from the market. We avoid the tool that could produce inadequate results. Unfortunately, people do not try to remember such bad experiences, clearly. "I followed the result of tool A, but it was too hard with many stairs." "I followed the result of tool B, but I could not make it. The estimate for the walking time was too short for me." These could be mine or the others with sighs, at that moment. Japanese have faced more occasions to encounter such. At last, those made the trend.

Anyway, HyperDia needs train station names. I use the map to locate them. Then, why not to start from that map. I use GoogleMaps, but there are others. Bing, for example.

Without a JRP, I may suggest to go to Nippori on a Tokyu, then line up a queue at the Tokyo station for a non-reserved seat. Or, take an LCC bus to Tokyo-Yaesu, next to the Shinkansen platform.

For a higher end. I may take a limousine to Tokyo. And take a Nozomi there.

These could be seen on GoogleMaps, but not likely by a train HyperDia. With an advent of GoogleMaps, no experts would be needed. Otherwise, we need to explain in detail why that would be better.

It is the Japan forum only where residents speak of non-GoogleMaps. GoogleMaps is famous in other nation forums in the English speaking community. By the existence of Japan Rail Pass? Then use this
https://world.jorudan.co.jp/mln/en/japan-rail-pass/
I could not imagine the Japan-Rail-Pass site with a resident HyperDia lover.
