>I don't see any problem with that map, the ratios are mostly correct.

Whaaaaat?

You see the island off the southern coast of the Korean Peninsula, colored red? That's Jeju.

The Japanese island chain is almost unrecognizable; but the largest southern island ought to be Kyushu. In the real world, Kyushu extends significantly south of Jeju and is about twenty times the land area.

The small green island near to and west-south-west of Jeju is Taiwan. In the real world, that distance is more like 700 miles and more like south-south-west. Taiwan is also much larger than Jeju.

At the northern end of Japan, the NK map has Hokkaido as a tiny cross-shaped island on about same latitude as Pyongyang. In fact, it's 75% the size of North Korea and extends significantly past the northernmost extent of the country.

In the real world, Sakhalin - the long, thin island north of Japan - doesn't overlap at all with North Korea's latitudes.
