Tanchon is a major port and industrial center located in the northeastern part of South Hamgyong Province in North Korea. The city stretches along the coast of the Sea of Japan at the picturesque mouth of the Namdae River. Possessing the rugged charm of an important industrial hub, it draws attention with its scale and role in the regional economy.

The city is home to more than 345,000 people and covers an extensive territory that combines coastal lowlands and mountain ranges. The history of this region dates back to the deep past—the first mentions of a settlement called Pokchu date back to the beginning of the 12th century, which gives the modern industrial appearance of the city a special historical dimension.
Tanchon is primarily known as a "miners' city" thanks to its rich deposits of magnesite, zinc, and cobalt. For a traveler interested in industrial architecture and the daily life of port cities, Tanchon offers a unique atmosphere where the rhythm of life is set by ports and railways. A visit to this city allows you to see the unvarnished, working side of the country's life, hidden behind the austere facades of industrial giants.
