Gunkanjima is an uninhabited island that is located approximately 17.5 km southwest of Nagasaki prefecture in Japan. Today it’s well known as a photogenic tourist spot, but it once flourished as a center of coal mining, which brought a number of huge profits to the country. What makes it special is the unique scenery created by the giant wrecked concrete buildings that used to be residential complexes for those who worked there. Seen from a distance, the shape of the island looks like a Battleship, which is translated as “Gunkan” in Japanese! In this article, we will introduce a brief story of Gunkanjima, an abandoned island, and what to see there!

Brief History of Gunkanjima (in the 19th Century)
It is generally believed that the coal mine in Gunkanjima was first discovered in 1810. During that time, Japan was governed by the Tokugawa Shogunate, which opened in 1603 and continued to rule the entire country for over 260 years. Around the end of the Tokugawa Shogunate, which fell in the late 18th century, the number of coals extracted on the island was relatively small, and it was recognized as a side business for local fishermen to get an extra income.
In 1890, the island was sold to Mitsubishi, one of the most powerful and largest companies in Japan, and it became their private property for over the next 100 years. They started to develop the island as a new center of coal mining. Several mine shafts were opened, which enabled them to reach the underground where more coals were stored. In 1897, the production of coal finally exceeded that of Takashima, another coal mining island situated in Nagasaki. As the development continued, other facilities such as an elementary school were completed to provide a better living environment for mine workers and their families.
Brief History of Gunkanjima (in the 20th Century)
In 1916, a giant concrete residential complex was completed to accommodate a number of residents. The complex consists of 7 floors, and it was the first concrete residential complex in Japan, and newspapers repeatedly described the island as a battleship. This is how Hashima, the official name of the island, was replaced with the nickname Gunkanjima, which is currently used and recognized more widely.
The quality of coals mined on the island was highly evaluated, which was dedicated to supporting the fundamental development of modernization in Japan. It also led to the rapid construction of a range of facilities for mine workers, which included medical facilities, educational opportunities, and even entertainment facilities. The first movie theater on this island was opened in 1927.
On the other hand, mine workers were forced to work overtime, which reached almost 12 hours a day. In the early 20th century, they started to hire younger workers, women, and even people from Korea and China to solve the labor shortage.
Brief History of Gunkanjima (During World WarⅡ)
During WWⅡ, the annual amount of coals hit the peak with the production of 410,000 tons in 1941. In spite of the historical achievement, however, it also had a dark side which clearly appeared in the devastating living environment of mine workers. According to some records, almost 40% of the population lost their lives from 1939 to 1945 due to tragic accidents such as mine explosions.
Brief History of Gunkanjima (After World WarⅡ)
The situation drastically changed after the living environments were improved after WWⅡ. The Labor Union was officially established in 1946, which resulted in a wage increase for mine workers. They were also able to have more leisure time to spend freely at a range of facilities. A number of buildings such as residential complexes, public baths, hospitals, and schools were started to build during the period as well.
In 1960, the population of the island reached almost 5,300 which made it the highest populated area in the world at the time! The density of the population was 9 times larger than that of Tokyo, which can be very convincing because the small island was packed with residents.
The island itself functioned as an independent city with great infrastructure and essential services for residents.
Brief History of Gunkanjima (Closure of the coal mines & coming back as a tourist attraction!)
As a result of the Energy Revolution which encouraged the switch of energy resources from coal to oil and gas in the 1960’s, the island started to face a decline and gradually lost power. It was finally closed in 1974, and the inhabitants had no choice but to leave the island.
The abandoned island was brought back into the spotlight again in 2009 when it was finally allowed visitors to enter the island. It was also officially designated a UNESCO World Heritage Site as a part of “Sites of Japan’s Meiji Industrial Revolution”, which includes historical and cultural sites relevant to the modernization of Japan!
