This video, titled "Traveling Japan with only an instant translator | ili," was released by "internationally ME."

The translator shown in this video is called ili, and it's a very handy tool for traveling abroad.
You don't need to be connected to the internet at all, and it's a one-way translator that automatically translates the words you speak into the language you want to translate.

It's small enough to fit in your pocket, and can be used with Japanese, Chinese, English, and Korean.
In the video you can see someone using ili in Asakusa, Japan. Be sure to check it out!
