Six of Yasujiro Ozu's movies have titles that directly allude to seasons:
Early Spring (早春, 1956)
Late Spring (晩春, 1949)
Early Summer (麥秋, 1951; I think the title literally refers to the time of wheat or barley harvest)
The End of Summer (小早川家の秋, 1961; literally, The Autumn of the Kohayagawa Family)
An Autumn Afternoon (秋刀魚の味; 1962; literally, The Taste of Autumn Swordfish, which apparently is a type of macquerel)
Late Autumn (秋日和, 1969; literally, The Calm of an Autumn Day)
There is also the movie titled in translation Equinox Flower (彼岸花, 1958). The
higanbana of the Japanese title is
Lycoris radiata, the spider lily, which flowers in autumn, and is associated in Japan with funerals, and with meeting people you will not see again. Higan is a Buddhist festival which takes place twice a year, in spring and autumn, so I am not completely sure if this counts as a season word.
Overall, there is a lot of autumn, but maybe not as much as you would expect, considering that the recurring theme in Ozu's films is aging parents finally separating from their children, sometimes willingly, sometimes unwillingly.
Ozu, in my view, is one of the greatest film directors of all times, and probably the one I have watched the most (not counting John Ford and John Huston, whose westerns used to run again and again on television when I lived with my parents). Both visually and emotionally, there are few directors I enjoy more. Wim Wenders probably would agree; a lot of his Tokyo documentary,
Tokyo-ga, is devoted to him. In that film, Wenders goes on a pilgrimage to Ozu's grave in Kamakura, and so did I, a few years ago:
