Factual error: In the Shinkansen fighting scene, the railway line is seen having color light signals along its way. But the Shinkansen uses a signalling system that doesn't involve the use of light signals at all.
Factual error: The bombing altitude for Nagasaki was 30 000 feet (~10 km), but in the opening scene the planes bombing Nagasaki are a lot lower than that. The bomb also detonated at 1,500 feet, not at ground level as shown. (00:03:25)
Factual error: In the scene where Wolverine fights the ninjas on the bullet trains: 1) the shinkansen bullet trains are electric and have pantographs and overhead power lines - neither are visible. 2) None of the bullet trains have skylights.
Answer: The chronology of the X-Men film series is, to put it mildly, somewhat screwed up. The first movie was released in 2000 and is described in an on-screen caption as being set in "The not too distant future", which isn't the most helpful statement, could be two years, could be ten years, who knows. The Wolverine is set about two years after the events of X-Men: The Last Stand, which is in turn about a year after the events of the first movie, so think about "the not too distant future", whatever that means, and add about three years onto that. This does mean that, yes, it is indeed set some decades after the events of the Origins movie, during which he lost his memories. It is, however, also set after a period during which he worked with Professor Xavier to regain some of his memories. It could therefore be suggested that Logan remembering his experience at Nagasaki represents that they had at least a partial success in recovering some of his memories.
