The way "Twenty-four Eyes" is filmed, is period-typical for a movie, especially one that is not about action but tries to explore characters. I watched more than a few western films from the fourties and fifties, so I was already familiar with the style of acting and filming, as well as the sound quality (especially voices and singing have a special "ring" to them, which is hard to describe.) For people who are not used to this, the movie might feel strangely slow and static.

With 2 hours and 36 minutes, the film is quite long, even for modern standards. There are three parts:
First, we meet the twelve children and her teacher in the first grade. For both the children and the teacher their roles at school are new and unfamiliar -- and while it might seem as if not much is happening, the freedom and serenity of this first hour is a good contrast to the following parts. After a time skip of five years, teacher and children meet again in the children's sixth grade, the last obligatory school grade back then -- we'll see how both the children's families and the growing nationalism (with it, the looming war) will shape their futures. And, lastly, vignettes of the following years of war and death, and how it impacts even that small Japanese island. There's also some time dedicated to the aftermath -- children, now young adults with their own kids, and the teacher reunite, look back to their shared past and then into the future.

I think for anyone who wants to watch this in the 21st century, it is important to be aware that the year that the film was shown
in cinemas -- 1954 -- is only nine years after the end of World War Two. So, these children (young adults in the later parts) could have been themselves, their children, their brothers, sisters, husbands and wives. I can imagine that the film was cathartic for the audience back then; it definitely must have had a stronger emotional impact than it could ever have for me.

Besides the emotional journey, and the reminder of how nationalism and senseless wars (and all wars are senseless) will destroy lives, for me the film also gave me a chance to see Japan as it was 70 to 90 years ago. We get to see two rural schools and a glimpse of teaching and learning; we see the houses in the fishing village; we hear people's thoughts on poverty, proper manners, women, family. I loved seeing how the style of clothing changed from 1928 to 1946.
(The film had the advantage that everything was very recent, so sets are probably authentic buildings and streets, and the people who made it could just remember how it was. No extra research needed.)

There are quite a few scenes that were very poignant, such as the teacher's despair that nationalist teachings had overtaken everything at school, or the scene after the war ended when her eldest son is not able to grasp that everything he believed was now supposed to be wrong.

One thing that I was a bit disappointing was that the songs's texts (the children sing quite often) were not translated in the subtitles. I think these were mostly Japanese folk and children's songs, and the texts probably underlined the emotions of the scenes -- but the international audience won't know them. It's not the fault of the film, but disappointeing nevertheless.

Overall, if you have the chance to watch it, do so!
