NH37 HND → CTS

NH37 distance and great-circle path

NH37 covers 820 km, or 510 miles. That makes it a short-haul flight, a single-aisle hop where turnaround time matters more than range. Of the 255 routes we track, it ranks 234 by distance.

The plane leaves Tokyo heading north. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the HND–CTS route appears on a tracker map.

Why NH37 block time differs from cruise time

The schedule allows 1.6 hours from gate to gate. That works out to about 518 km/h. A Boeing 777-200 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Winds aloft shift the real flight time by up to an hour in either direction. See what really moves flight times.

What to know about NH37

• Time change: none. Both cities keep the same clock, so arrival time reads exactly as you expect.

We track 2 scheduled services between Tokyo and Sapporo, split between All Nippon Airways and Japan Airlines. Among them, it is the first departure of the day on this route; it is scheduled quicker than anything else on the pairing; it is the only one flown with a Boeing 777-200.

Measured against NH37, which pushes back at 08:00:

• JL515 (Japan Airlines) leaves 1 hour later and is given the same block time, on an Airbus A350-900.

Block time is gate to gate, so it counts taxi at both ends. That is why two flights covering identical distance rarely share a scheduled duration.

Our database contains 2 observations of NH37 across 2 UTC dates in this window, most recently 2026-07-29. Those records contain 2 distinct transponder addresses.

The median recorded visibility was 50 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.
