Republic of Korea(Korea)

The language is Korean.

Utility poles have diagonal yellow-and-black stripes. Taiwan's utility poles use the same stripe pattern.

Warning signs are orange.

Pine trees are common.

Bollards have a distinctive shape.

There are mountainous areas inland to the northeast and southwest, and roads there can have mountains visible on both sides.

In traditional hanok houses, ondol (underfloor heating) apparently developed in the north, while wooden plank flooring developed in the south.

Jeju is an oval-shaped volcanic island, and like the Canary Islands (also volcanic), its soil is often dark-coloured, with plenty of silver grass, similar to Kyushu. Since it has only a single peak at its centre, no road here runs between two tall mountains, though there are a fair number of hills a few dozen to about 100 metres high.

Udo (Udo Island) sits off the east coast of Jeju and has a similar feel to Jeju. The soil is dark and dark stone walls are common, but since it's a fertile plateau, nearly everywhere except the roadless area in the southeast is farmland, with almost no forest or tall mountains.
