Hello. I'm going to Tokyo for 14 days and I was wondering if it is really necessary to buy a JR pass? I won't be traveling by shinkansen, only with the tokyo subways. Can I buy normal subway tickets and are they expensive, or do I have to have a JR pass?
I'm very grateful for any answers!
If you are just in Tokyo, you don't need a JR pass. You can buy normal tickets from machines or staff (machines are easy to use, even without Japanese - just look for your station on the map above the machines, check it's price code and press the button). In comparison to Shinkansen services, prices are surprisingly reasonable, and work out cheaper than in places like London.
There are a range of day and short term passes that might be of use to you on certain days if you are travelling more than 3 or 4 times (sometimes even less). Note that subways are run by 2 different companies, and different one day tickets will allow you use one or both.
In order to save hassle, it's also worth getting a SUICA card, which is basically a smart card that you can top up (validity is 10years from last useage....) and swipe to use, thus you can top it up when you buy it, and just use it as and when without having to worry about individual tickets. You can get one at the airport easily enough. They are also valid on most buses (it will eventually be all), all local trains, subways etc etc.
Thank you so much for the information, very helpful :D
