The sea route from Los Angeles (United States) to Tokyo (Japan) is about 4,938 nautical miles, which is 9,145 km or 5,683 statute miles. That is about 4% longer than the direct great-circle line, because the practical route follows coastlines and shipping lanes.
Voyage time by boat speed
Time underway is distance divided by speed. These are continuous-passage figures with no stops or weather margin.
| Boat and speed | Time underway |
|---|---|
| Sailboat, conservative (5 kn) | 41d 4h |
| Sailboat, average (6 kn) | 34d 7h |
| Displacement trawler (8 kn) | 25d 17h |
| Fast trawler (10 kn) | 20d 14h |
| Planing motor yacht (15 kn) | 13d 17h |
| Fast motor yacht (20 kn) | 10d 7h |
Planning estimate, not navigation
This distance is computed over the open Eurostat shipping-lane network. It is a realistic passage length for planning, but your sailed distance will differ with weather routing, currents, draft, and the exact berths you leave from and arrive at. Always verify against official charts.
Plan this passage properly
Open Los Angeles to Tokyo in the Marine OS route planner: it suggests the sea route, then you drag waypoints, set your speed and fuel burn, and check weather and tides along the way.

How far is Tokyo from Los Angeles by sea?
About 4,938 nautical miles (9,145 km / 5,683 statute miles) along the practical sea route. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Los Angeles to Tokyo?
At a typical sailing average of 6 knots it is about 34d 7h underway. A 10-knot trawler needs about 20d 14h, and a 20-knot motor yacht about 10d 7h. Add margin for weather, currents, and stops.
How is this distance calculated?
It is computed over the open Eurostat global shipping-lane network, the same kind of network freight routing tools use. It is a realistic planning estimate, not a navigation product: your sailed distance will vary with weather routing, draft, and the exact harbors you use.
