A Silhouette in the Sea
Nine miles off the coast of Nagasaki, Japan, a graysilhouette rises from the East China Sea. From a distance, it looks like abattleship anchored in silence - walls of concrete, smokestacks, andfortress-like cliffs. This is Hashima Island, better known as Gunkanjima,or Battleship Island, one of the most enigmatic abandoned places in the world.
For nearly a century, Hashima Island was a symbol of Japan’s rapid industrialization. Beneath its seabed, coal fueled the nation’s factories, trains, and warships. Above ground, concrete apartment blocks housed thousands of families, creating what was once the most densely populated placeon Earth. Today, it stands silent. Its apartments are hollow, its schools empty, its cinema long dark. What remains is a ghost city - a haunting reminder of ambition, suffering, and abandonment, slowly being reclaimed by the sea.
Coal and Concrete: The Birth of Hashima Island
From Barren Rock to Industrial Powerhouse
In 1887, the Mitsubishi Corporation began mining coal beneath Hashima Island, transforming what was once a barren rock into athriving outpost of Japan’s industrial revolution. As demand for coal grew, Mitsubishi expanded the island, reinforcing it with massive seawalls and reclaiming land to make space for buildings. By the early 20th century, the company had transformed Hashima into a concrete city in miniature - complete with schools, hospitals, bathhouses, shrines, and even a pachinko parlor - all packed into just 16 acres.
Families lived in towering apartment blocks - Japan’s first high-rises - built not for glamour but for survival against typhoons and the harsh sea winds. The island’s nickname, Gunkanjima, or Battleship Island, comes from its silhouette, which resembles a warship, with massive concrete buildings rising from the sea like a naval vessel’s turrets. This fortress-like appearance stands as a testament to the engineering feats of the time, as well as the harsh conditions that necessitated such robust construction.
Life in the World’s Most Dense City
By 1959, over 5,000 people lived on Hashima Island, giving it a population density nine times greater than Tokyo. Children ran through alleys so narrow they were nicknamed "rabbit warrens." Residents joked that you could cross the island without ever stepping into sunlight, weaving from building to building through a maze of staircases and rooftops. The island had its own rhythm - a strange mix of hardship and community.
Life on Hashima was claustrophobic but not joyless. The island had its own unique culture, shaped by the isolation and the constant presence of the sea. Bathhouses were the center of social life. Everyday after work, miners and their families bathed in communal baths, washing away coal dust and gossiping in the steam. Children played on rooftops, their playgrounds perched above the sea, where laundry lines flapped like sails.Cinema nights brought the community together, films flickering in the darkwhile storms raged outside the walls. The hospital treated everything from mining injuries to the inevitable lung diseases caused by coal dust.
Food was shipped in from the mainland, water collected ingiant tanks, and every inch of land was used. Life was precarious, but residents often recall a strange fondness for the island - a sense of family,of survival together at the edge of the sea.
The Darker Side: Forced Labor and War
A Hidden History of Exploitation
Hashima Island’s story is not just one of industrial triumph. During World War II, as Japan’s empire expanded, labor shortages were filled with forced workers from Korea and China. Estimates suggest between 800 and 1,300 forced laborers were sent to the island during the war. These men were brought to Hashima against their will, working long hours in suffocating mines. Conditions were brutal: 12-hour shifts, searing heat, coal dust filling lungs, and little food. Many died from exhaustion, malnutrition, or accidents. For these men, Hashima was no community - it was a prison.
Survivors later described being treated as disposable tools, with escape impossible on an island surrounded by seawalls and ocean. The deathtolls are estimated to range from 137 to 1,300, depending on the source. The forced laborers were subjected to beatings, starvation, and deaths by accident or exhaustion. Their suffering is a dark stain on Hashima’s history, one that cannot be erased.
Controversy and UNESCO Recognition
When UNESCO declared Hashima a World Heritage Site in 2015,i t sparked international controversy. South Korea, North Korea, and China condemned the move, arguing that Japan was downplaying its wartime atrocities. The inclusion of Hashima in the UNESCO list was particularly contentious because it was seen as a symbol of Japan’s industrial revolution without adequate acknowledgment of the suffering of forced laborers.
Japan eventually acknowledged the suffering of forced laborers as part of the island’s history, and the site was approved for inclusion on the UNESCO World Heritage list under the condition that Japan formally recognize the suffering of those who were forced to work there. However, tensions remain, and the issue continues to be a point of contention between Japan and its neighbors.
Decline and Abandonment: The End of an Era
The Shift from Coal to Oil
After the war, Hashima returned to its industrial routine. But by the 1960s, oil had replaced coal as Japan’s primary fuel. The mines grew unprofitable, and in 1974, Mitsubishi announced the closure of Hashima. Within weeks, the island was abandoned. Families left in haste, carrying what they could. The rest - furniture, photographs, toys - was left behind.
The abandonment was sudden and total. One day, the island was a bustling community; the next, it was a ghost town. The final ferry departed, leaving behind a densely packed island of apartments, schoolrooms, and communal spaces, all eerily intact. For nearly 35 years, Hashima remained completely off-limits, an isolated ruin battered by typhoons and the harsh saltair of the East China Sea. This period of abandonment earned it a new nicknameas a “ghost island,” shrouded in mystery and cut off from the public.
Nature Reclaims the Ruins
For decades, Hashima was left to the elements. The concrete towers began to crumble under typhoon winds. Windows shattered. Sand and saltcrept into walls. Today, Hashima looks like a bombed city, its hollow apartments open to the sky. The island’s abandoned infrastructure has been left to the elements since its evacuation in the 1970s, resulting in crumbling buildings and unstable pathways.
The island’s eerie beauty has made it a subject of fascination for photographers, urban explorers, and historians. The surreal images captured on Hashima - chairs still in classrooms, toys in the dust, rusting tricycles in hallways - have cemented its reputation as one of the world’s most photogenic ruins.
Battleship Island in the Imagination
Pop Culture and the Allure of Ruins
Hashima’s haunting beauty has made it a pop culture icon. It inspired the villain’s lair in the James Bond film “Skyfall” (2012), where its eerie ruins served as the backdrop for a dramatic showdown. The island also appeared in video games like “Call of Duty: Black Ops II,” further cementing its status as a symbol of mystery and intrigue.
Countless documentaries and photo essays have explored Hashima’s ruins, each offering a glimpse into the island’s past. The 2017 South Korean film “Battleship Island” brought this history to a wider audience, though it mixed fact with fiction. The movie sparked controversy in Japan, where its depiction of events was criticized, but it also reignited global interest in Hashima’s complex history.
Tourism and the Ghosts of the Past
In 2009, tours to Hashima officially opened, though only along reinforced walkways. Visitors cannot enter the collapsing buildings, but they can see the skeletal towers, the sea walls, and the iconic school building. The contrast is striking: bright tour boats arrive from Nagasaki, unloading visitors with cameras, while the ruins loom like an apocalyptic city scape.
On clear days, you can see how close the island is to the mainland - and yet how isolated it must have felt. The “rediscovery” of Hashima invigorated the local economy around Nagasaki, but it also reignited debates about how to responsibly preserve and present its history, both as a marvel of industrial ambition and as a site of forced labor and human suffering.
Why Hashima Endures
A Symbol of Industrial Rise and Fall
Hashima is more than a ruin. It is a symbol of the rise and fall of industry, of human ambition pushing against nature, of exploitation hidden beneath progress. Its story is not just Japanese - it is global: the story of coal, of empire, of migration, of abandonment. Every city built on industry has its Hashima, but here the ruins remain, preserved in salt andsilence.
The island’s history spans three periods of Japanese history: Meiji (1868–1912), Taishō (1912–1926), and Shōwa (1926–1989). These were times of industrialization and hegemonic expansion, during which Hashima played a crucial role in Japan’s economic and military growth. The island’s industrial exploitation existed over the course of these periods, with the longest and most controversial activity occurring during the Shōwa period, which included World War II.
The Ghosts in Concrete
Hashima is haunted not by phantoms, but by memories. Standing on the seawall, you can almost hear the sound of thousands of lives compressed into a tiny island - children laughing, hammers striking, waves crashing against the walls. Then you imagine the silence after 1974, the voices gone, only wind and sea filling the emptiness.
Some say the island carries two sets of ghosts: the nostalgic ghosts of families who remember it with affection, and the darker ghosts of forced laborers who never left. Both are part of its shadow, and both remain etched into its crumbling concrete. The island’s spooky reputation is not derived from mystical legend but rather from the very real struggle branded onto its concrete facades.
Visiting Hashima Today
How to Get There
Access to Hashima is strictly limited to guided tours due to safety concerns. The island’s abandoned infrastructure has been left to the elements since its evacuation in the 1970s, resulting in crumbling buildings and unstable pathways. Tours depart from Nagasaki Port and take about 40 minutes to reach the island.
Visitors are not allowed to explore the island freely. Instead, they are guided along reinforced walkways that offer views of the island’s most iconic ruins. The tour includes stops at the island’s school, apartment blocks, and the remains of the coal mining facilities. The experience is both eerie and fascinating, offering a glimpse into a world that has been frozen in time.
What to Expect
Visiting Hashima is like stepping into a time capsule. You’ll walk along observation spots that offer stunning views of the island’s abandoned buildings, including the crumbling apartment blocks, staircases leading nowhere, and the remains of schools and workplaces that once echoed with life.
The island’s most famous structure is Building 65, the largest dormitory building for workers on Hashima. Its skeletal remains standas a testament to the island’s past, a silent witness to the lives that were once lived within its walls. The school building, with its empty classrooms and rusting desks, is another poignant reminder of the island’s abandoned community.
The Legacy of Hashima
Hashima Island is a paradox - an ode to human ingenuity anda tombstone to the lives that have been sacrificed in the name of progress. Its spooky reputation is not derived from mystical legend but rather from the very real struggle branded onto its concrete facades. As tourism and time erode its physical presence, Hashima remains a haunting testament to the cost of industrialization - and the ghosts, either literal or metaphorical, that refuse to rest.
To visit Hashima is to stand on the edge of human history, staring at a concrete battleship with no crew, anchored forever in the sea. It is a place that forces us to confront the past, to remember the lives that were lived and lost, and to reflect on the legacy of industrialization and the human cost of progress.
