That is about 71% 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) | 85d 18h |
| Sailboat, average (6 kn) | 71d 11h |
| Displacement trawler (8 kn) | 53d 15h |
| Fast trawler (10 kn) | 42d 21h |
| Planing motor yacht (15 kn) | 28d 14h |
| Fast motor yacht (20 kn) | 21d 11h |
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.

How far is Tokyo from Lisboa by sea?
About 10,292 nautical miles (19,060 km / 11,843 statute miles) along the practical sea route, which transits Strait of Gibraltar and Suez Canal and Bab-el-Mandeb and Strait of Malacca. The straight-line distance is shorter, but boats follow coastlines, channels, and traffic lanes.
How long does it take to sail from Lisboa to Tokyo?
At a typical sailing average of 6 knots it is about 71d 11h underway. A 10-knot trawler needs about 42d 21h, and a 20-knot motor yacht about 21d 11h. 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.
