Here is an example for a text annotated using JGloss. It is the story "Kari no Douji" by Kenji Miyazawa. I downloaded the original text from the Blue Sky Collection. As you may have already noticed, my English is not perfect, and my Japanese is even worse. The translations are only chosen to allow basic understanding and will often be imprecise or just plain wrong.
