What's the best way to get around Tokyo with metro? I've been looking into options that include the ride from HND to the city and then to NRT. There seem to be multiple day passes that include either the Tokyo Metro, Toei Subway, and/or JR. I also read that often it's not worth it to buy a day pass if you're just going to a few places.
It seems to cost 200 yen for a ride, but the airports are a lot more. Also last time I was in Tokyo they had tickets that were only available to foreigners. Do they still exist? Any ideas of best tickets to buy?
