Everyone has used Google-Sensei's fantastic Image Search feature to find things online. Sometimes it gives you whacked results, but most of the time it's pretty spot-on.
That being said, most people probably don't think about it being used as a dictionary. Think about it for a moment and it will make sense. If you type in "banana", Google-Sensei will return a wide array of photos featuring bananas. If you enter "car", you'll get a variety of content featuring cars. Why not apply this to language learning? Why not apply this to Japanese?
For example, in the article image I entered "バナナ" (banana). Behold, photos of bananas! The next time you are stuck on a word, type it into Google-Sensei's image search. The image feedback has the added bonus of helping it stick in your brain.
That is all.
