I downloaded it because I sometimes watch Japanese foreign films on Netflix and have to rely on the subtitles. It might be nice to actually understand a word now and then, but it would great to use as a teaching tool and it is simple enough for grade school age children.
On one page there is a picture of the item and the word in English. On the next page is the word in Japanese in both how it would be written and how it would be spoken. You also don't need a Kindle; Amazon has a free Kindle for PC's program that you can download and read right from your computer.
To download, click here.
As Amazon is always changing what his free (check before clicking purchase), I recommend hurrying over and grabbing a download while they are still available.
