If you understand Japanese, the recently uploaded movie "Zone of Emptiness" may be of interest.

[gggg gggg]

According to Chatbot BARD:

I think the film "Zone of Emptiness" is a powerful and moving adaptation of the novel by Hiroshi Noma. It is a film that is both visually stunning and emotionally resonant. The film does an excellent job of capturing the atmosphere of the novel, and it brings the characters to life in a way that is both realistic and sympathetic.

The film is particularly effective in its depiction of the dehumanizing effects of war. The characters are all struggling to find their place in a world that has been turned upside down by war. They are all searching for meaning and purpose, but they are all finding it difficult to find it in a world that is so full of violence and chaos.

The film is a reminder of the human cost of war. It is a film that will stay with you long after you have finished watching it. I highly recommend it.
