The Volcanic Island Where Residents Once Wore Gas Masks
Miyak Jima, the island that breathes poison. In the vast Pacific Ocean southeast of Tokyo lies a small, remote island. Beautiful, volcanic, alive. This is Makajima, a place where time stands still in the air. Can kill you. At first glance, it looks like paradise. Lush forests, dramatic coastlines, ancient shrines nestled in greenery. But there’s something off. A tension in the wind. A silence that doesn’t feel peaceful. It feels like warning because this island sits on the edge of destruction. At its heart is Mount Oyama, an active volcano with a violent past. It has erupted six times in the last century. But the most devastating came in the year 2000. Without warning, the mountain exploded, blasting toxic gases into the sky. Ash rained down like snow. Animals fled. Over 3,000 residents were evacuated, forced to abandon their homes, unsure if they would ever return. But the eruption didn’t just end in fire. It left behind something worse. A slow invisible poison, sulfur dioxide, leaking from the earth in deadly doses. And it never stopped. Even today, over two decades later, the island still breathes poison. When people finally returned in 2005, they came back to a world forever changed. Gas detection alarms are installed throughout the island. They beep, they flash, they warn. Residents must carry gas masks at all times, even children. There are places where the gas is so concentrated. A single breath can burn your lungs. This isn’t a drill. This isn’t some dystopian future. This is daily life on Makajima. But here’s the real mystery. Why do people choose to stay? Maybe it’s tradition. Maybe it’s resilience. Or maybe it’s because they’ve learned to live with the monster beneath them. Here, nature is not a backdrop and it’s a character. unpredictable, dangerous, sacred. Some say you can hear the mountain at night, a deep rumble, a hiss through the trees, as if the island is breathing. The gas masks aren’t just tools. They are a symbol of survival, of surrender, of a fragile piece between humans and the earth itself. Tourists still visit, curious and cautious. Some say it’s one of the most surreal experiences in Japan. Walking through a town where everyone’s face is hidden, like ghosts with eyes. And when the sulfur gas rises, you see it roll down the hills like fog. Not thick, not fast, but heavy, alive. Makajima is not just a place. It’s a warning that beauty can be deadly. That the earth is never truly silent. And that some people choose to live with danger rather than run from it. So if you ever visit Makajima and you hear the low groan of the volcano beneath your feet, remember you are standing on a ticking clock. And the island, it’s breathing and it never forgets.
Miyake-jima Island, Japan: The Volcanic Island Where Residents Once Wore Gas Masks
Miyake-jima (三宅島) is a volcanic island located approximately 180 kilometers (112 miles) south of Tokyo, Japan, in the Izu archipelago. Part of the Fuji-Hakone-Izu National Park, this island is renowned for its active volcano, Mount Oyama, and a fascinating history that has shaped life for its residents in unique and dramatic ways.
The island’s volcanic activity is not just a distant geological feature—it’s a powerful and ever-present part of life. In the year 2000, a series of eruptions from Mount Oyama released large amounts of sulfur dioxide gas, forcing a complete evacuation of the island. Residents were not allowed to return for five years. When they did, they were required to carry gas masks at all times due to the continued emission of toxic gases—a rare and surreal reality that turned Miyake-jima into a symbol of human resilience in the face of nature’s force.
Today, while the volcanic emissions have significantly decreased, Miyake-jima remains under constant monitoring by Japan’s Meteorological Agency. Despite these risks, the island is home to a small but dedicated population and has become an unusual tourist destination for those interested in volcanology, ecotourism, and disaster history.
In addition to its volcanic intrigue, Miyake-jima is a haven for bird watchers and divers, offering rich marine biodiversity and scenic natural landscapes shaped by lava flows and ocean winds.
With Google Earth, you can explore Miyake-jima from a bird’s-eye view—tracing the contours of its volcanic crater, coastal cliffs, and rugged beauty. This virtual journey brings you closer to understanding how people and nature coexist in one of Japan’s most geologically active regions.
