The film follows the last 2 decades in the life of Hyakken Uchinda, a writer and teacher who retires in the war years of the early 1940's. His students venerate him in his old age, and join him and his family each year for a ritual birthday party, asking "are you ready?" to which he answers, "not yet," acknowledging that death may be near, but life still goes on.
Kurosawa is considered to be one of the greatest filmmakers of all time and this, his final and touching film, is the perfect ending to a lifetime of cinematic achievements.
