Another great train website and app is HyperDia. It is mainly for train navigation making it the perfect companion for the Japan Rail Pass. It provides accurate bullet train and non-bullet train routes and schedules across Japan.
Google Translate is an app I use almost everyday. Pull out your camera and get a quick rough translation of a restaurant menu and street sign using the “instant camera translation” feature.
Days ago I came across HappyCow.net, a site for finding vegan and vegetarian restaurants nearby. I used the site to find several spots that I plan to frequent on my trip. There is also an app that covers over 180 countries, Japan included of course.
For many trips I’ve watched my friends wave their phones in and out of the Tokyo subway stations. Now that I have an iPhone I can do that too. Today I added the Balance app that provides the balance of my Pasmo card. I also can add it to my Apple Wallet so I can use my iPhone to tap in and out at stations, making it easier and more efficient to get around Tokyo.
