Mr. Thank You, a short story by Yasunari Kawabata
A film version is made by Hiroshi Shimizu
A bus driver, nicknamed Mr. Thank You due to his expressions of gratitude to other road users who give way on the narrow mountain roads, drives from rural Izu to faraway Tokyo. The film portrays the passengers and their diverse reasons for travel, like a mother and her daughter who is destined to be sold in Tokyo, and the people they meet on the way, including a Korean working woman who makes funeral arrangements for her deceased father. In the end, Mr. Thank You marries the daughter to save her from her fate.
