For Parents
If I had young children, I would not let them watch this movie. I strongly advise watching Grave of the Fireflies first and then deciding if or when your own children might be ready for it.
Savage Japan Misc. Tidbits
Another amazing movie that comes to mind that fits into this category of "significant but difficult to recommend" films is Lars von Trier's Breaking the Waves. It stars one of my favorite actresses, Emily Watson. Ms. Watson became one of my favorite actresses, perhaps my most favorite, as a result of her incredible performance in that film.
I saw Breaking the Waves in a theater a decade ago when it was first released. I bought it on DVD out of respect for the production. I have had the movie in my possession for many years, but I've found that I cannot bring myself to watch that film a second time because of its power and ability to induce tremendous emotional pain. Just like Grave of the Fireflies, I don't know if I will ever feel strong enough to watch Breaking the Waves again. I should add that Grave of the Fireflies affected me much more powerfully than Breaking the Waves.
I decided to add the "extras" disc for Grave of the Fireflies to one of my rental queues, and I am waiting on it now. I may add some comments about it here after viewing. That disc has an interview with the original author of this story that I am curious to hear.
For Japanese Language Students
I have found the language used in Japanese animated films is often very good for Japanese listening comprehension practice. Animated stories typically have family elements intertwined that contribute greatly to the very basic and important vocabulary words in play. The scripts being written to be manageable by younger viewers helps as well.
Grave of the Fireflies was so overwhelming, I chose not to focus on learning Japanese during my viewing of the film. If you are brave enough to watch this movie, I advise taking a break from language progression concerns and simply absorb this story as the rare and powerful experience it is.
I do recommend watching the film with the original Japanese soundtrack and subtitles, even if you are not studying Japanese. I think there is more depth in the experience when you hear the natural and originally intended audio.
