Hi. I'll be in Japan for 26 days and will be using the 21 day JR pass of the 1st part of the trip. For the remaining 5 days, I'll be in Tokyo and am wondering what Open Ticket passes should I get to get the best out of it. My hotel is located at Kuramae Station. Assuming I visit 3 location a day, I will be taking the train at least 4 time a day. Which option do you suggest I go for.
Here are my choices:
1) 2 x Special 2-Day Open Ticket + 1 x Special 1-Day Open Ticket
This ticket is very reasonably priced but only restricts me to only Tokyo Metro lines and Kuramae is not a Tokyo Metro station. The next nearest Tokyo Metro station I believe should be Asakusa Station which is a little too far for walking. What do you think?
2) 5 x Tokyo Combination Ticket
I believe this will be the most expensive option out of the 3 but the good thing is I'm covered for almost all the stations. Is it worth the money?
3) ICOCA card
Since ICOCA card will be compatible through Japan for most trains, I should be able to use it for almost all the stations in Tokyo. Pay as I travel, will be a good but will it be more expensive than the above 2 option because I'll be paying regular fare for all my trips? Or is will it be cheaper if I use this?
Or maybe should I use both option 1 and 3. Use ICOCA between Toei station and the Special Open Ticket for Tokyo Metro Station.
What do you suggest? Base on your experiences, is it convenience to travel around Tokyo via only Tokyo Metro trains?
