Goofs

When Sato has Charlie cornered in the parking garage, and is about to behead him, he looks back at Conklin, and draws a weapon. That looks to be a Wakizashi (a Japanese side-sword to accompany the much larger Katana). As he rides off to behead Charlie, he is scraping along the ground a much larger sword.

The orientation of the shotgun after Sugai's bodyguard tosses it to Nick.

When the Yakuza godfathers arrive for the climactic meeting at the vineyard, the sun is shining as they get out of their cars. In the reaction shot of Nick watching them, it is unmistakably raining.

When Conklin is taken to the tea house, one of Sugai's men first throws a pump-action shotgun, then a handful of shells at his feet. As Conklin picks up the shells, a total of six can be counted on screen. However, in the firefight that follows, he fires only three shots before running out of ammo.

In the nightclub scene when Masahiro walks over to Nick and Charlie's table, he is holding a cocktail with an umbrella in it. The cocktail umbrella keeps changing it's canopy shape, from convex to concave between shots.

Though the movie takes place in Osaka, Japan's second city, none of the Japanese characters speak in the Osaka dialect. Rather, they all speak the standardized dialect, which is based on the Tokyo accent. Persons from Osaka would normally speak standard Japanese to somebody from another region, but it would be almost unheard of, in particular in the underworld, amongst people from Osaka.

In several scenes, Japanese characters can be seen opening and shutting taxi doors. In fact, doors of Japanese taxis are always operated by the driver, through buttons near the driver's seat; so this would never happen.

When Sato was brought back from New York to Osaka by Nick and Charlie, the airplane seen in the scene was Northwest Airlines Boeing 747-200. However, after they land when Nick tries to catch Sato after being taken by the fake policemen, it is clearly seen that the aircraft registration was N159US. In reality N159US is a Northwest Airlines McDonnell Douglas DC-10-40 not a Boeing 747-200.

The paper signed on the airplane in Japanese is a real estate agreement. When they meet at the police station they are told they signed an insurance form. This, however, could be explained by the Japanese police captain's mixing up the English terms "real estate" and "insurance".

When Miku is visiting the bank to obtain the note plate, in every shot from her flat to the bank she is clearly wearing black hosiery. As she strips to change, she is already wearing taupe colored pantyhose.

She was already wearing the taupe colored pantyhose underneath the black ones in order to change outfits quicker.

The motorcycles are clearly small capacity (125, 250 or so) single cylinder trials bikes, probably two-strokes, but they produce the roar of a four-cylinder liter-size street racer.

As part of the Yakuza initiation, new members will alter their bike to make as much noise as possible. They are then required to ride up and down a particular stretch of road revving their engine.

Nick, an experienced police officer should be aware he's not allowed to carry a firearm in another country.

He knows this full well, but as the early scenes in New York clearly establish, he is a rebellious character who is known to bend, and even break the rules, on a regular basis.

In New York, Nick and his former partner are being investigated by Internal Affairs for stealing drug money on a bust, but that would not have been possible as Nick tells one of the investigators that they have thirty homicides a week, meaning that he is a homicide detective and not a narcotics detective so there is no way he should have been on any drug busts which is Narcotics Division and they work homicide.

Nick could have been accompanying Narcotics Division detectives on a joint investigation, or he could have been transferred from Narcotics to Homicide subsequent to the bust.

Towards the end of the movie, Nick shoots a hole in a bed sheet hanging on a clothes line, but the pre-cut hole is visible before it is shot.

Obvious stunt double for Conklin during the motorcycle chase near the end of the film.

At the end where the plates of the $100 bill are shown under the shirt, it clearly shows the "1" of "100" next to the portrait of Benjamin Franklin, but on the real $100 bill it's the last "0" of "100" next to Franklin.

When Conklin shoots the man with his shotgun, the wire is visible as he gets pulled backward through the door.

In the nightclub scene when Masahiro joins Nick and Charlie, while they sitting on the coach. There's a short moment when an extra passing behind Nick shows a middle finger right in camera.

During the restaurant scene when Conklin is running out to chase the Yakuza, and fires on them with his weapon, he is using a snub-nose .357. If you watch later in the meatpacking district, when he is looking for Sato, he is only using a .38. He didn't have a second gun, they changed the weapon mid-scene.

The 12 gauge rounds thrown after the pump action shotgun before the final showdown have their primers already stricken, hence have been fired.

In the beginning of the movie when Conklin races the other motorcycle, they shift to a higher gear about 15 times with a 5 gear bike. With that many gears on the back end, they would have been going about 300 MPH.

Towards the end of the film, in the section where Nick and Sato are fighting. Sato pushes Nick onto the bike wheel, and then they cut to Sato punching the ground. In the following shot you see Nick grimacing and in the background you see a blond-haired guy wearing a green tracksuit type top quickly duck behind a tree.

During the mud fight at the end, when the bikes crash, the camera is splashed with drops of mud and one drop is seen briefly traveling down the surface of the lens.

In the final fight Nick gets kicked in the stomach and hits a tree. During that fight, Michael Douglas is obviously wearing padding under his shirt.

Right after the Stakeout scene, the woman is seen walking away. The scene the cuts from a fishing port in Osaka to what is supposed to be the Osaka City Center area. If you look closely at the signs in the city scene, you would be able to tell that the location was switched to Kobe.
