Continuity mistake: When Mr. Miyagi is trying to capture a fly with his chopsticks he finally does, and the fly is captured about 2 inches from the end of the chopsticks. The tips of the chopsticks are crossed with the fly in the middle. When the camera cuts to the side angle while Daniel is driving up and before Mr. Miyagi releases the fly, the fly is now trapped at the very end of the chopsticks and the tips of the chopsticks are not crossed. (00:09:45)
Continuity mistake: At the start, when Daniel and Miyagi are at the back of Miyagi's house, Miyagi walks up to the new wood housing. On the housing's ledge there is a pot for nails, a measuring tape, a knife and a small pot behind the nail pot. A few shots later, the measuring tape and knife have both vanished. (00:10:50 - 00:12:55)
Continuity mistake: At the start, the postman gives Miyagi a letter from Okinawa, and when the postman says "Okinawa," the postman is holding the letter lengthwise. Then when Miyagi goes to take it, he is holding it widthwise. (00:14:45)
Continuity mistake: When Daniel and Miyagi are outside the village, Sato pulls up in his car and gets out. Then when Daniel and Miyagi look at him their positions change in the following shot. (00:39:35)
Continuity mistake: When Chozen hits Daniel in the stomach, on the bridge by the village, one of Chozen's friends kicks the drum under Daniel to the other side of him, but when the girl hurls the vegetable at Chozen, it is back where it originally was. Also, when the girl hurls the vegetable he looks over his shoulder to his left, yet in the closeup he is looking over his right shoulder. (00:55:25)
Continuity mistake: When Daniel goes sightseeing with the Japanese girl, they have a little running race to the castle. When they both stop running Daniel says "You cheated," and he is pointing at the girl with his right hand, but when the shot changes he is pointing with his left hand. (00:59:50)
Continuity mistake: Daniel is supposed to break six pieces of ice. We see the man putting the six pieces in the slots. The shot where Daniel is approaching the ice their are only four pieces of ice. We then see two shots with six pieces of ice. When Daniel finally breaks the ice there are once again only four pieces of ice in the rack. (01:07:30 - 01:08:25)
Continuity mistake: When Daniel is about to break the six pieces of ice, the slabs of ice change from shot to shot. In one shot the 5th piece from the left is peaked and taller than the others. In the next shot of the ice the 3rd piece from the left is the tallest piece of ice. (01:07:50)
Continuity mistake: When Miyagi goes to see Sato at his house, at the opening of this scene, Miyagi and Sato's assistant walk rather close to Sato in one shot, but when it cuts to behind Sato, Miyagi and the assistant are much further away. (01:08:00)
Continuity mistake: When Sato goes to see Miyagi, but he isn't there, Chozen destroys the dojo then tells his two friends to let Daniel go, and they throw him forward. His hands are not in the fighting stance, yet in the following shot he is now in his fighting stance with his hands at the ready. (01:15:25)
Continuity mistake: At the end, when lots of people are dancing in the castle, it cuts to a man banging the drums and the music stops. Miyagi and his lady friend are standing in front of the fountain in the middle and Daniel is to the left of the screen, but in the following shot Miyagi and his friend are right in front of Daniel. (01:37:40)
Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Factual error: After Miyagi and the kid have the conversation with the military man they drive off and round a corner. A scene is shown of the sea and very visible is a shot of "Chinaman's Hat" Island. A feature that if you have ever been to Oahu, Hawaii near Kualoa Point you would know is on the island of Oahu and not in Okinawa where the movie is supposed to take place. See Chinaman's hat at this site: http://www.hawaiiweb.com/oahu/sites_to_see/chinamans_hat.htm.
Factual error: In the scene where Mr. Miyagi and Daniel arrive in a taxi at a construction site, the taxi is stopped by a U.S. Air Force airman first class. The airman asks, "Where you going, buddy?" Mr. Miyagi says, "Tomi village." The airman says, "Never heard of it! This is Kadena Air Base." He then calls out to an off-screen person, "Sarge! Tomi village?" The off-screen voice replies, "You're standing on it, corporal!" The U.S Air Force has never had the rank of corporal in its organization.
Continuity mistake: When Daniel uses the Miyagi drum technique against Chozen at the end of the film, the third blow travels from Daniel's left to his right. So Chozen should falter back to his own left. But when the shot cuts back to over Daniel's shoulder, the blow sends Chozen to his right instead.
Continuity mistake: When Mr. Miyagi and Daniel meet Sato in the garage, Chozen throws Daniel's book about Okinawa on the ground. Daniel then picks up the book and holds it by its short side. In the next shot, we can see that Daniel somehow now holds the book by its long side.
Revealing mistake: When Daniel and Kumiko first see the storm coming near the end of the film, the wind outside is blowing the trees sideways. They open the door to run out and the camera shows what is outside. The trees there are not moving.
Continuity mistake: When Miyagi is showing Daniel the "Drum Technique" by the water, Miyagi sends the hook thing flying at Daniel. Daniel goes flying into the water and gets soaked. You can tell if you look at his shirt, it is stuck to his chest. He then climbs back up and a few seconds later, he is A LOT drier.
Visible crew/equipment: When Daniel and Mr Miyagi are walking along the street (near the time where Daniel uncovers the "weights scam" on the scales of the vegetable buyer), the camera dolly handle is plainly in view at the bottom of the screen. (Fullscreen)
Continuity mistake: When Daniel helps the man with the carrots the amount of them changes between shots.
Answer: "You are crazy."
