Is it possible to have a day trip tour to Hakone from Tokyo? thanks

Yes you can..make sure you done enough homework.

Also, i see that a lot people choose DisneySea over Disneyland in this forum. which is recomended for visitors with 20-23 years old age group?

Both also Best....if have to choose eithier one...then you prefer dry or wet.

Mostly ppl chose DisneySea becoz itz oni available at Japan... Both parks are unique at itz own way... BTW, Disneysea is not really consider as wet park like Sunway Lagoon...
p/s : u may consider going to Universal Studio Japan (USJ) if u are going to Osaka... i feel Disneyland/ Disneysea is more suitable for age 16 and below, while USJ will be >20... the games are more exciting in USJ...

Hyperdia

fully utilize this link when u at Japan... trust me... very useful...   

i still dun really understand how does the pass work..after reading tonnes of websites. 

Tokyo Metro,Toei Subway,and JR East will only need SUICA/PASMO card rite?

Suica/Pasmo are same as Malaysia Touch N Go. 
Tokyo Region they used Suica / Pasmo
Fukushima they used Sugoca
Hokkaido used Kitaca / Sapica
Kansai (Kyoto + Osaka + Kobe ) Region used ICACO
Nagoya used Toica

Different placed got different company making their Touch N Go card.

if i wan to use Hankyu and Keifuku line in Kyoto,which is the suitable pass to use huh? does Kansai Thru Pass cover these 2 lines as well? thanks.

IF you go Kansai Area...you need 2 pass. 

1 are Kansai Area Pass...(for JR Company buses / Train )  It only can used in JR Company Line  << 2 Day Pass are 4000 Yen & 3 Days Pass are 5000 Yen
1 are Kansai Thru Pass ( for others company operator trains in Kansai Area except JR Company) << 2 Day Pass are 3800 Yen & 3 Days pass are 5000 Yen

If lazy used Pass...then buy ICACO card. (Kansai Touch N Go )


Emm...If you going Tokyo + Kansai together...I suggest you buy JR Rail Pass...then it cover everything including Shinkansen.  SInce it cover everything then you no need any Suica / Pasmo / any kansai area Pass......But you still need Kansai thru Pass for the Kyoto area buses and discount for Kyoto heritage ticket   

How to get it....this you have to do your own homework
For more info....do your own homework

thanks a lot.. now i noe which one to use d.

wanna ask the shinkensan route as following:
tokyo > osaka > kyoto > hakone > tokyo ?? got such route ???

from the above url the route is exclude hakone.

tokyo > kyoto > osaka > hiroshima > tokyo
can i from osaka direct back to tokyo instead of above route ?

i have a rough idea wher to go but need some details in it to make it more fun 
so, i need some experience people to give some idea what to do at the partiular place... cause this is my 1st time to japan 
the plan is as below: 
fuji mountain - at there the whole day and one night
disneyland - at there the whole day and one night one night
shopping (this is where i need some sugestions) any location i can go to and it is near to the airport? (can travel by train)

i know the coasting will be high (word of mouth) it cause around Rm100++ >.<

but my route is mt. fuji, ---> disneyland --> tokyo shipping (need opinion)

or i can do it any other way? cause my mom booked the mt fuji >.<

Seem like you travel to Japan frequently. So nice~
