Buy JR pass in Malaysia

4 of us intend to visit Tokyo,Kobe,Kyoto & Osaka within 13days(Jul 2011), need to know if it's worth it to purchase JR? Also how to get it in Malaysia

it's worth it to purchase JR?

It depends on the details of your itinerary. For example, A one way trip from Tokyo to Kyoto to Osaka to Kobe, for example, will not pay off. But a Tokyo-Osaka-Tokyo round trip by regular shinkansen tickets costs about the same as a 7-day Japan Rail Pass.

Note also that you could travel even cheaper by overnight buses:

Also how to get it in Malaysia

Here are some authorized agents:

Or you could purchase it online by credit card:

Tq for the info, basically the whole trip goes like :

Tokyo- Disneyland (3D2N)
Kyoto - 4D3N
Osaka - 4D3N

how long will it take to tvl Tokyo-Kyoto by rail? Saw the bus journey takes abt 8hrs

So are you flying into Narita, and flying out of Kansai international airport, meaning, only going one way from Tokyo to Osaka/Kyoto? Then even a 7-day Japan Rail Pass does not pay off. If you are going one way, then you can just buy single Shinkansen tickets.

Tokyo - Kyoto by JR Shinkansen train takes about 2.5 hours.
