There seems to be a lot of OzBargainers travelling to Japan these days so I thought this would be useful to some. Especially those who are planning to stay in Tokyo as it is cheaper than the regular tickets and allows unlimited travel. Also allows you to save your JR Rail Pass for longer journeys or buy a shorter pass as required.
The Common 1-day Ticket for Tokyo Metro & Toei Subway (¥1,000) which allows for one day of unlimited rides on all Tokyo Metro and Toei Subway lines is currently available at stations. However, the new Tokyo Subway Ticket will be available to domestic and international tourists for a great value price set lower than this Common 1-day Ticket for Tokyo Metro & Toei Subway.
1-Day Ticket is valid for one day of unlimited travel and costs only ¥800
2-day ticket is valid for two consecutive days of unlimited travel and costs ¥1,200
3-day ticket is valid for three consecutive days of unlimited travel and costs ¥1,500
Valid on all Tokyo Metro lines and all Toei lines.
Where to Buy: Airport sales counters (Narita or Haneda) or regional travel agencies.
For those who only need the Tokyo Metro lines you can get slightly cheaper 1 or 2 day passes.
Can we also get a "How do I keep track of all of those different lines" guide, lol. I'm used to using subways but that was pretty tricky given the language barrier.
