Both involve older Japanese women, often reminiscing on their pasts and their dissatisfactions in life; they often recount specific childhood memories, and trace these memories back to the person they'd become, abandoning the life they thought they should have been living for a new way of life that brings them true happiness.
(they also both operate under a romantic slant!)
