About this app
Finding your way in Tokyo isn't the hard part. The real challenge is something else. "Can I take this route with my pass?" "Will it cost extra?" "Which of these routes should I pick?" Google Maps shows you plenty of routes, but you have to figure out for yourself which one works with your pass. DokiDoki takes that worry off your plate. Register the pass or IC card you already have — Tokyo Subway Ticket, JR Pass, IC Card, and more — and it lays out the routes that fit it, clearly. We don't tell you which pass to buy. We help you make the most of the pass you already have. No more stopping at the ticket gate to figure it out. Forget the extra-fare worries and just focus on enjoying Tokyo. And T, your Tokyo travel friend, comes along for the ride.
