You would expect a sinking airport to have better things to do, but this Japanese airport balances its existential crisis with ensuring it never loses a bag.
Sitting on an artificial island, it’s been slowly dropping into the sea since the 1990s.
Still, while the entire facility shifts, its baggage record remains spotless.
Yes, for more than three decades, the airport hasn’t lost a single piece of luggage. Ever.
The Japanese airport isn’t going to disappear…for now
Opened in 1994, Kansai International Airport was designed to solve a major problem: overcrowding in nearby Osaka.
The solution was bold, even by Japanese engineering standards: constructing an entire airport on a man-made island.
But almost immediately, the island began to sink faster than expected.
Engineers had predicted some settling, but the soft seabed beneath it compressed more than anticipated, causing the airport to drop about 40 feet over the years.
That might sound like a disaster happening in slow motion, but airport authorities have found a solution.
Engineers have continuously adjusted the structure, raising seawalls, reinforcing foundations, and even jacking up parts of the terminal to compensate.
Today, the rate of sinking has slowed significantly, and the airport remains fully operational, handling tens of millions of passengers each year.

Now here’s where things get truly impressive.
While Kansai has been fighting off the ocean, it has also maintained a perfect record when it comes to baggage handling.
Not a single checked bag has been officially reported lost since the airport opened.
That’s almost unheard of in global aviation.
Baggage handlers are simply different in Japan
To put that into perspective, baggage mishandling is still a regular issue in the United States.
According to recent industry data, major US airlines mishandle between 0.49 to 0.90 bags for every one that makes it on the plane.

That includes delayed, damaged, and yes, lost luggage.
While most bags are eventually reunited with their owners, the experience is still frustratingly common for travelers.
So how does Kansai do it?
It comes down largely to culture.
Japanese airports are known for meticulous attention to detail, and Kansai takes it to another level with highly coordinated baggage tracking systems and ground staff who treat every suitcase like it matters.

In the end, Kansai International Airport manages to do the unthinkable, quietly proving that even a sinking airport can outperform the rest of the world where it really counts.
Meanwhile, across the Pacific, travelers in the US are still refreshing tracking apps and filing claims, hoping their suitcases didn’t decide to take a vacation of their own.
