You’ve seen the photo. Five Marines and a Navy corpsman hoisting the Stars and Stripes atop Mount Suribachi. It’s arguably the most iconic image of the 20th century. But honestly, most people’s knowledge of the Iwo Jima campaign begins and ends with that single snapshot. We think of it as a triumphant moment, a peak of American heroism. In reality? That photo was taken on the fourth day of a thirty-six-day meat grinder. The men in that picture weren't celebrating a victory; they were just catching their breath before heading back into a literal hellscape.
Iwo Jima is a weird place. It’s a speck of volcanic rock in the middle of the Pacific, officially part of the Tokyo Metropolis despite being over 700 miles away from the city. It’s technically called Iwo To now—the original Japanese name—but for history buffs, it’ll always be Iwo Jima. It’s eight square miles of black sand, jagged rocks, and the constant, oppressive smell of rotten eggs thanks to the sulfur vents.

The Strategy Behind the Slaughter
Why did anyone want this place? It’s a valid question. The island has no harbor. It has no fresh water. It’s basically a wasteland. But in 1945, it was all about the runways.
The U.S. was pummeling Japanese cities with B-29 Superfortresses launched from the Mariana Islands. The problem was the distance. It was a 3,000-mile round trip. If a bomber took damage or ran low on fuel, they were basically doomed to ditch in the ocean. Iwo Jima sat right in the middle of that flight path. Plus, the Japanese were using the island's radar to tip off Tokyo whenever the bombers were incoming. Taking the island meant emergency landing strips for the Americans and silencing those early warning systems.
But General Tadamichi Kuribayashi knew the Americans were coming. He didn't plan to win. He knew he couldn't. His entire strategy was to make the conquest so bloody and so psychologically scarring that the U.S. would think twice about invading the Japanese home islands. He forbade his men from doing the typical "Banzai" charges that had characterized earlier battles. No more suicidal rushes into machine-gun fire. Instead, he told every soldier to kill ten Americans before they died.
To do this, he turned the island into a sponge.
He didn't defend the beaches. He let the Marines land. He let them get bogged down in that miserable, soft volcanic ash where you can't even dig a foxhole because the sides just cave in. Then, he opened fire from 1,500 hidden pillboxes and a massive network of tunnels.
Life Inside the Tunnels
We’re talking about 11 miles of tunnels. These weren't just holes in the ground; they were sophisticated bunkers with electricity, ventilation, and rooms for thousands of soldiers. Some of these tunnels were so deep that the heat from the volcanic activity made the air inside reach 122 degrees Fahrenheit. Imagine fighting a war in a sauna while the ground literally reeks of sulfur.
The Japanese soldiers lived there for months. They were starving, dehydrated, and suffering from various tropical diseases. Yet, they didn't surrender. Out of the roughly 21,000 Japanese defenders, only about 1,000 survived to be taken prisoner. The rest? They died in those tunnels or in the scrub brush.
When you look at the casualty counts, it’s staggering. Iwo Jima was the only battle in the Pacific where the total American casualties (dead and wounded) exceeded the Japanese. It was a slaughterhouse. Admiral Chester Nimitz famously said that on Iwo Jima, "uncommon valor was a common virtue." He wasn't exaggerating. The sheer number of Medals of Honor awarded for this one island—27 in total—represents over 25% of all those given to Marines during the entire war.
The Island Today: A Restricted Zone
You can’t just buy a ticket to Iwo Jima. You can’t hop on a ferry from Tokyo and go for a hike. It’s a closed military base operated by the Japan Self-Defense Forces.

Access is strictly controlled. Most years, there’s a "Reunion of Honor" where veterans and their families from both sides come together to remember the dead. It’s one of the few places on Earth where former mortal enemies stand side-by-side in shared grief. Aside from that, the only way most people see it is via chartered "overflight" tours that circle the island but never touch down.
The landscape is still treacherous. Unexploded ordnance is everywhere. Even decades later, Japanese recovery teams are still finding the remains of their fallen soldiers in the collapsed tunnel systems. It’s estimated that the remains of over 10,000 Japanese soldiers are still buried somewhere in that black sand.
Why the Name Changed
In 2007, the Japanese government officially changed the name back to Iwo To. Why? Because that’s what the locals called it before the war. "Jima" and "To" both mean island in Japanese, but the kanji can be read both ways. The Japanese naval officers who fortified the island mistakenly called it Iwo Jima, and the Americans picked it up from them. After years of petitions from former residents who were evacuated in 1944, the government finally made it official. However, to the rest of the world, the "Jima" name is so deeply embedded in history that it’s unlikely to ever truly fade away.
The Controversy of Necessity
There’s a lingering debate among historians about whether the battle was actually worth the cost. Some argue that the B-29s could have made it without the island, or that the Japanese radar could have been neutralized through bombing alone.
They point to the fact that while 2,251 B-29s landed on Iwo Jima by the end of the war, many of those landings weren't "emergencies" in the strictest sense—they were just convenient stops. Was the lives of nearly 7,000 Marines worth a gas station in the Pacific? It's a heavy question. But for the crews of those bombers who did lose engines or ran out of fuel, that strip of black sand was the difference between life and a watery grave.
Traveling (Vicariously) to Iwo Jima
Since you probably won't be stepping foot on Mount Suribachi anytime soon, the best way to understand the island is through the lenses of those who were there.
- Flags of Our Fathers & Letters from Iwo Jima: Directed by Clint Eastwood, these two films are essential. Letters is particularly powerful because it’s told from the Japanese perspective, based on the actual letters of General Kuribayashi.
- The National Museum of the Marine Corps: Located in Triangle, Virginia, this museum holds the actual flag from the second raising (the famous one).
- The Ogasawara Islands: If you want to get as close as possible, you can visit the Ogasawara chain. They are UNESCO World Heritage sites and offer some of the most pristine diving and hiking in the world. They give you a sense of the geography without the military restrictions.
Exploring the Legacy
The legacy of the island isn't just about military strategy. It’s about the human capacity for endurance. On one side, you had young Americans, many still teenagers, being thrown into a "meat grinder" against an invisible enemy. On the other, you had Japanese soldiers who knew they were going to die and chose to hold their ground in a subterranean furnace.
If you’re looking to truly grasp the weight of this place, start by looking at the work of combat photographers like Joe Rosenthal, but don't stop there. Read the accounts of the "Navajo Code Talkers" who played a massive role in the communication on the island. Their contribution was vital because the Japanese were expert code-breakers, but they could never crack the Navajo language.
Actionable Steps for History Enthusiasts
- Check the American Battle Monuments Commission (ABMC): They maintain the records for the fallen and provide incredible digital mapping of the cemeteries where Iwo Jima veterans are laid to rest.
- Visit the Iwo Jima Memorial in Arlington: It’s more than just a statue; it’s a site of active pilgrimage for Marines. Watching the sunset parade there is a different experience entirely.
- Read "Sands of Iwo Jima" by Richard Wheeler: He was a corporal who was actually there during the flag-raising. His prose is gritty and lacks the "Hollywood" sheen that often coats these stories.
- Support remains recovery efforts: Organizations like Kuentai-USA work to identify and repatriate the remains of soldiers left behind in the tunnels. It’s a grim task, but it’s the only way to bring closure to the families who still have "missing in action" names on their family trees.
Iwo Jima remains a scarred, silent witness to the extremes of human conflict. It’s a place where the earth itself seems to remember the violence, still venting steam and sulfur as if it’s trying to boil away the memories of 1945. It isn't a place for casual tourism; it’s a monument to the fact that sometimes, the smallest dots on a map carry the heaviest weight of history.
