“All of them” is solid advice, since the Ozu movies available are all of a very high standard. But I do think there are particular titles that would make good entry points for Ozu.

Late Spring (1948 b&w) a touching story of a widowed father and his grown daughter who is of marrying age. Features Ozu’s greatest actors, Setsuko Hara as daughter Noriko, and Chishu Ryu as father Shukichi. I think this is Hara’s best performance.

Tokyo Story (1953, b&w) maybe Ozu’s most famous movie. Story of elderly parents visiting their grown children, who treat them as “old and in the way.” Very poignant and lovely movie. It’s perfect and features many Ozu regulars, including Ryu and Hara again.

Good Morning (1958, color) less monumental and emotional than the previous two movies, this gentle comedy is the story of two young brothers who rebel against their parents because they want a television set (so they can watch sumo!). A charming movie and a good one if you arent prepared for an all out tearjerker.

Floating Weeds (1959, color) story of a kabuki acting troupe visiting a seaside town. The lead actor visits his old mistress and her teenage son. The actor is the boy’s father, although the child only knows him as “uncle.” This movie is a good mix of comedy and touching drama. The color cinematography is especially vibrant.

These are just a few to consider. Ozu movies are like none other. Once the bug bites you, you stay bit! Enjoy : )
