It has just been announced that the Tokyo Anime Fair and the Anime Contents Expo have become one convention. We will be looking for a second anime convention to attend to replace the Anime Contents Expo date. More information in the link below.
An interesting app that i did not get a chance to use yet is Google Translate. This app allows you to speak and it will translate to text. There is also the option to draw out the Japanese characters if you don't know how to use the Japanese keyboard in your phone.
While in Japan you may want to call home. Having a phone will ding you with expensive charges and renting a phone in Japan will so the same. so, what do you do? you get Skype. Using skype you can call home for a lot less than with normal phones. With an unlimited data plan mobile hotspot you can call from anywhere. one other thing you can do is video call someone and show them things on your trip as well. please be respectful when doing this.
