Earth Sandwich / City antipodes / Fukuoka

Antipode finder · Japan

The antipode of
Fukuoka.

Draw a straight line from Fukuoka (33.60° N, 130.42° E) through the centre of the Earth and it comes out at 33.60° S, 49.58° W, in the South Atlantic Ocean, 273 km from the nearest dry land, off the coast of Brazil. The other slice of an Earth sandwich would sink.

Two globes: one centred on Fukuoka, one centred on its antipode at 33.60° S, 49.58° W

Can you make an Earth sandwich from Fukuoka?

No, not from Fukuoka itself. The other slice would land in the South Atlantic Ocean, 273 km from the nearest dry land (Brazil), where the sea floor lies about 2,360 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 321 km from Fukuoka, 33 km from Ponggae-dong, South Korea. Its other slice would go down 30 km from Santa Vitória do Palmar, Brazil.

How this was worked out: the antipode flips the latitude and moves the longitude by 180°. Land or sea comes from the OpenStreetMap coastline the map uses; the sandwich verdict and elevations come from the verifier's 0.2° grid (Natural Earth land, ETOPO 2022 relief); water names from Natural Earth; towns and populations from GeoNames. The city's position is GeoNames' point for it; a big city's suburbs spread tens of kilometres around that point, and the figures move with them. Generated 2026-09-29.
