Ueno Station to Tokyo DisneySea

Hello, i'm Cynthia from Indonesia

This is the first time for me, to going Japan. I wanna ask to Japan.Guide, if i want go to Disneysea from Ueno Station.. What must i do? Thanks before :)

Google Map can give you the answer actually.

Change to the Keiyo Line at either Tokyo Station or Hatchōbori Station to Maihama Station and take the resort line in from there.

Hatchobori might be more suitable since Tokyo Station is big and might take awhile to find the correct line.

check out hyperdia. Most helpful site for train travel. All visitors to Japan should check out this site and have it on their phones. It lists all the information you need. Those who ask whether a certain rail pass is worth it or not, you can do your homework on this site and figure it out for yourself.

I disagree.

There is no route-finder tool to suit each purpose of every traveler in any situation.

HyperDia is just one among many tools of this kind.
I think that HyperDia is not recommendable for first-time Japan travelers.

When you use a route-finder website or application,
you had better not just swallow the time data
but see some extra time.
Timetables may be revised before your actual train ride.
Time between the two suggested train rides
may be too short for you to make that transfer.

Hyperdia has its drawbacks. More than once has a person confused Fukuoka with Hakata and if they blindly followed Hyperdia, they'd be in for a rude awakening. It is a good tool, but it's to be used in conjunction with other resources.

No;
route-finder tools (like HyperDia)
have no function to check whether a particular rail pass pays off or not.

There seems to be a common misconception
to think as if your total railway cost were always calculated by adding up the costs by legs.

To estimate your actual JR cost
and judge precisely whether a JR pass is suitable or not,
you have to know some rules about JR basic fare and surcharges,
which first-time Japan travelers may not know well in advance.

Will you travel solely?
Where is your starting point?

From a place which is close to subway Ginza Station of Tokyo Metro,
it sounds better
to go by Hibiya Line to Hatchobori
and make a transfer to JR Keiyo Line,
compared to trying a long transfer in Tokyo Station.

Tokyo Station is big and might take awhile to find the correct line.

Yes;
while there are many signs in English,
the above-ground platforms and the Keiyo Underground platforms
are apart both vertically and horizontally from each other.

(Personally I have made this long transfer for many times
since the Keiyo Line reached Tokyo Station;
toddlers may well feel it tiring.)

to Maihama Station and take the resort line in from there.

You walk for a while
from Maihama Station South Exit to the Disney Resort Line station.
