Tora-san, an itinerant peddler who is thrown out of his father's house twenty years before but reconnects with his aunt, uncle and sister Sakura. Tora wreaks some havoc in their lives, like getting drunk and silly at a marriage meeting and ruining Sakura's chance to marry someone, as well as just being a real pain to those around him. There is a sentimental side to him also, and the best way to describe him is that he grows on you.

Tora-san visits brother-in-law Hiroshi's hometown to attend a memorial service for his late father. When the local temple priest becomes intoxicated, Tora-san wearing the priest's robe delivers the memorial speech, much to his family's surprise. Thinking he's found his true calling, Tora-san decides to join the order, and falls for the priest's divorced daughter.

Tora-san is inspired to pursue an education after a visit to the grave of a woman he met years ago. When he returns to Shibamata with the intent to study, he falls for Toraya's new tenant instead.

After a chance encounter with Hiroshi's father on a bus, Tora decides to get serious and reflect on the mortality of man. His plans are derailed when a beautiful lady starts working at Toraya.

During his travels, Tora-san gets drunk with an old man in Kyoto. Though Tora-san never fully comprehends his importance, the old man is a Living National Treasure ceramist. At his home, Tora-san makes a good impression on the old man's maid, who apparently falls in love with Tora-san.

In the summer of 1941, the United States and Japan seem on the brink of war after constant embargos and failed diplomacy come to no end. "Tora! Tora! Tora!", named after the code words used by the lead Japanese pilot to indicate they had surprised the Americans, covers the days leading up to the attack on Pearl Harbor, which plunged America into the Second World War.

这是一部真实的电影，真实展现了日军偷袭珍珠港的历史。美军插手太平洋战场，日军最高将领山本五十六认为美军实力强大，应速战速战，不宜和美国人打长久战。于是，由他一手策划的偷袭珍珠港行动正式启动了。 　　虽然美军从此前截获的日军密电中得知了日军可能进行突袭的消息，但多数人都对此不屑一顾，密电的内容也没进行上报。即使在突袭当天美军一个士兵发现了雷达上不寻常的飞机群，美军将领仍然认为那是自己的飞机在执行巡逻任务。最终使得日军偷袭行动一举成功，美军损失惨重。山本五十六也成了美国人最大的眼中钉。
