The story, just like Death itself, is quite simple and could be told in a few sentences.

What makes this movie amazing is how script, settings, nature, music and acting make a whole that is more than the sum of it parts.
The script itself - a journey to self-discovery, a story about leaving and letting go --has some rearkable lines that could sound cheesy but the way they are spoken, feel like profound truths of life. The acting makes as much use of silence as of speaking. The ritual of nokan has few words spoken, but the body language of the nokanshi and the bereaved speak volumes.

The music with it's leitmotif of "the Traveller" bridges the gap between what we see and what we feel.
And nature itself follows the flow of the story. The ending of the dream happens in late autumn, the winter storms accompany the lowest point of Daigo's lfe. Spring brings new hope and new life.
Similarly, the houses tell the stories of their owners: The bath house is run-down but lovingly maintained, Daigo's house where his mother lived is full of her own life and the memories of Daigo's father, and last but not least, the Nokanshi's living space is full of green and flourishing plants.

All of this is done with lovingly attention to detail: The ritual itself, of course. But have you seen that when Daigo washes the bath house owner's body -- the bowl Daigo uses is one of the bath house's?

When so much of the movie relies on silences, on the music and on the settings themselves -- what use is a review that uses the written word? Go, watch for yourself and feel what you see and hear.
