Factual error: The picture of Ning-Po taken by the American tourist is nowhere near sharp enough - or high enough resolution - for it to be enlarged sufficiently for the ship's name to be legible.
Continuity mistake: When Bond is trapped in the light airplane flown by Osato's female pilot, she sets the airplane on fire and bails out. As she's exiting the plane, its landing gear is down. Once Bond frees himself and tries to recover the airplane, the landing gear is back up.
Other mistake: During the Little Nellie helicopter battle scene, the same footage of enemy copters being destroyed is used three times.
Continuity mistake: The first time we see the fake lake retracting in the volcano it is moving very fast, and before the cut it is almost totally retracted. But in the next clip when seen from below the opening is only half of the crater and the roof is retracting much slower.
Plot hole: The American spacecraft is said to be scheduled for launch at midnight Japanese time. But from the place in the movie where it is shown it is late afternoon or early evening.
Deliberate mistake: When 11 is dropped into the water and eaten by the piranhas, although the ravenous fish probably ate most of her and what was on her, there should at least be pieces of clothing that would rise to the surface in the flurry of activity. Not to mention that even though the water is a murky green all the blood from her body should have created a temporary, but very noticeable darkening of the water.
Plot hole: Other than a reason to advance the the plot the Americans have no reason to launch their second rocket. If they're prepared to go to war because they think the Russians will steal another rocket then don't launch the rocket. It's not like there is an urgency to get another rocket into space so as far as the Americans are concerned what is the hurry?
Factual error: When Bond enters the Sumo game, the writing above the door reads, "Beauty Parlour" in Japanese.
Continuity mistake: The stranger who is watching Bond's funeral through binoculars lowers the binoculars after Bond is thrown into the water - as if looking down on the water. But the binocular is so low he's actually looking into the table.
Plot hole: If a fake burial at sea and a picture in the newspaper was enough to convince Bond's enemies that he was dead, was it really necessary to have him shot at in the bed at the beginning? We learn later that the girl he was with was part of the fake death (and probably the gunmen too) so couldn't Bond's people have just started with the newspaper and burial at sea to begin with rather than risking his life in the process?
Revealing mistake: When the helicopter with the magnet drops the villains' car into the ocean, look carefully and you can see that the car is empty.
Continuity mistake: When Bond and Kissy reaches the crater's edge it is bright daylight and the sun is quite high up (that can be seen from the shadows on Bond's shirt). But when the reach the bottom of the crater it is night.
Factual error: In the beginning scene involving the U.S. spacecraft, as the front door on the unidentified ship starts to close around the U.S. capsule you can see the reflection of red light across the hull of the captor's ship. Where is this light coming from? It can't be from the sun, because sunlight only appears white to our eyes. (00:03:10)
Other mistake: When Blofeld blows up the crater at the end we see a shot of lava coming out of the top of the crater, but then we see a shot of the inside of the crater with all the bodies and barrels there is no lava. So where is the lava at the top of the crater coming from?
Continuity mistake: During the fight scene in Osato's office with the large goon, the villain's suit and shirt become disheveled and un-tucked, then straightened and tucked, several times as the shots change.
Factual error: When the Russians launch their ship, they are talking about Sputnik. In Russian, the technician says that it is 36 degrees while the English subtitle reads 72 degrees, which is not accurate. 36°C is 96.8°F.
Continuity mistake: When Bond's body is lowered down the ladder into the submarine it is glistening wet, but in the next clip when they start cutting it open, it is almost dry - and definitely not glistening anymore.
Revealing mistake: When Tanaka's train starts moving neither Bond, Tanaka nor the girl is seen to feel the acceleration. They stand/walk perfectly steady. That is impossible in an accelerating train. It is clear that it's only the lights moving on the wall.
