Quick answer: Nanjing to Osaka distance at a glance
Flight distance from Nanjing (NKG) to Osaka (KIX) is 965 miles (1,553 km, 839 nm) great-circle using real OpenFlights coordinates, with an estimated nonstop time of 1h 56m and route type medium-haul regional. Coordinates are 31.74°, 118.86° → 34.43°, 135.24°, bearing 74° east from haversine formula.
Facts computed from OpenFlights — not estimated. See methodology below.
The great-circle distance from Nanjing (NKG, China) to Osaka (KIX, Japan) is 965 miles (1,553 kilometers, 839 nautical miles). This is the shortest path a plane could fly between the two airports, measured along the surface of the Earth using the haversine formula on the airports' real published coordinates (31.74°, 118.86° for NKG; 34.43°, 135.24° for KIX). A nonstop flight on this route is estimated to take about 1 hour and 56 minutes, assuming a typical cruise ground speed of 500 mph including climb-out and descent. The destination lies roughly east of the origin (initial bearing 74°), placing the midpoint of this route near coordinates (33.09°, 127.05°).
By route type, this is a medium-haul regional flight. Medium-haul routes are usually nonstop on narrowbody aircraft such as the Airbus A320 or Boeing 737 — a 1.5–3 hour flight that rarely needs a connection. The destination's solar time zone is 1 hour ahead of the origin (see our time zone tool for the full breakdown). Estimated carbon footprint per passenger is about 87 kg CO₂ in economy, and the route difficulty score is 3/10.
Great-circle route from Nanjing (NKG, 31.74°, 118.86°) to Osaka (KIX, 34.43°, 135.24°). The dashed line is the shortest path between the two airports on the Earth's surface — the path a nonstop flight would follow. The midpoint at (33.09°, 127.05°) gives a sense of which region the flight overflies.
How this distance is calculated
TripRoute computes the great-circle distance between two airports using the haversine formula applied to each airport's published latitude and longitude from the public OpenFlights airports.dat dataset (the same data that powers airline route maps worldwide). The haversine formula accounts for the curvature of the Earth, so the result is the true shortest distance along the surface — not a straight line on a flat map. We express it in statute miles (965 mi), kilometers (1,553 km, conversion factor 1.60934), and nautical miles (839 nm, factor 0.868976). The estimated flight time assumes a ground speed of 500 mph including the climb and descent phases, which is a reasonable average for subsonic commercial jets — actual flight time varies with winds, routing, and the specific aircraft type. The compass direction (east, bearing 74°) is the initial great-circle bearing from origin to destination; the path curves slightly because of the Earth's curvature on long sectors.
TRWhen distance matters most for NKG → KIX
At 965 miles this sits in the narrowbody sweet spot, which usually means frequent nonstops and competitive fares on this medium-haul regional route.

Nanjing to Osaka — quick answers
How far is Nanjing from Osaka by plane?
The nonstop flight distance from NKG (Nanjing) to KIX (Osaka) is 965 miles (1,553 km, 839 nautical miles), measured as a great-circle line across Earth's surface using the airports' published coordinates. This haversine calculation accounts for Earth's curvature and matches airline navigation charts; actual flown distance is slightly longer due to airways and winds.
How long does it take to fly from Nanjing to Osaka?
Estimated nonstop flight time is 1 hour and 56 minutes, assuming a typical jet cruise speed of about 500 mph including climb and descent. Gate-to-gate time is usually 20–35 minutes longer for taxi and air-traffic routing, and connecting itineraries add 1–4 hours depending on layover length and airport connection efficiency.
Is NKG to KIX a short, medium, or long-haul flight?
This is a medium-haul regional flight (965 miles). Medium-haul flights are usually nonstop on narrowbody aircraft like the A320 or 737 with standard economy service. Flight categories follow industry distance bands that predict aircraft type and service level, so you can anticipate cabin options and connection likelihood.
