Maps are weird. Most of us grew up staring at the Mercator projection on a classroom wall, assuming that Greenland is roughly the size of Africa. It isn't. Not even close. Africa is actually fourteen times larger. We’ve been living with a distorted mental image of our own planet for centuries because flattening a sphere onto a piece of paper is a mathematical nightmare.
Enter Hajime Narukawa.
In 1999, this Japanese architect and artist decided to tackle the "orange peel problem." You know the one—if you peel an orange and try to press the skin flat, it rips or stretches. To avoid the rip, mapmakers usually stretch the poles. Narukawa’s solution, the AuthaGraph projection world map, changed everything by prioritizing area over traditional "up and down" orientation. It’s arguably the most accurate map we have that still fits on a flat surface.
It’s weird-looking. It’s asymmetrical. Honestly, it’s a bit disorienting at first. But once you see it, the Mercator map starts to look like a relic of a confused past.
The Problem with Being Flat
Geometry is stubborn. You cannot represent the surface of a sphere on a plane without distorting something. Usually, mapmakers have to choose their poison: do you want to keep the shapes of the countries correct (conformal), or do you want the sizes to be accurate (equal-area)?
Most maps choose shapes. This is why the AuthaGraph projection world map is such a radical departure. It’s based on a solid called a tetrahedron. Basically, Narukawa divided the spherical surface of the Earth into 96 triangles, projected them onto a tetrahedron (a four-faced pyramid), and then unfolded that pyramid into a flat rectangle.
Think about that.
Instead of wrapping a cylinder around the Earth like Gerardus Mercator did in 1569, Narukawa used a complex tiling process. The result is a map that maintains the proportions of landmasses and oceans with incredible precision. No more giant Greenland. No more shrunken Brazil.

Why the AuthaGraph Projection World Map Matters Right Now
In 2016, Narukawa’s design won the prestigious Good Design Grand Award in Japan, beating out over 4,000 other entries. It wasn't just because it looked cool. The judges recognized that our global perspective is shifting.
In a world defined by climate change, melting polar ice, and shifting geopolitical power, we need a map that shows the actual connections between continents. On a standard map, the Arctic and Antarctica are just white fringes at the top and bottom. They look like the edge of the world.
On the AuthaGraph projection world map, the poles are fully visible and integrated. You can actually see the flight paths across the Arctic Ocean. You can see how close North America and Asia really are. It’s a "tessellating" map, which means you can lay multiple copies of it side-by-side to create a seamless, infinite loop of the Earth. You can pick any point to be the "center."
That’s a huge deal. It removes the Eurocentric bias that has dominated cartography for 450 years. There is no "up." There is no "middle." There is just the surface of the planet, laid out as it actually exists in 3D space.
Comparing the AuthaGraph to Other Projections
Let's get real for a second. The Mercator map was designed for sailors. It’s great for navigation because a straight line on the map is a constant compass bearing. But it’s terrible for geography.

- Mercator: Inflates the poles. Makes Europe look massive.
- Peters Projection: Fixes the size issue but makes the continents look like "wet laundry" hanging on a line. Everything is stretched vertically.
- Robinson: A compromise map used by National Geographic for years. It looks "right" to our eyes but is mathematically inaccurate in almost every way.
- AuthaGraph: Keeps the area correct and the shapes mostly intact by sacrificing the traditional North-South grid.
The "Tetrahedral" Secret
If you look closely at an AuthaGraph map, you’ll notice the grid lines—the latitude and longitude—are curved and strange. They aren't the neat squares we're used to. This is the trade-off. To get the size of Africa right while also keeping the shape of South America recognizable, you have to warp the coordinate system.
Narukawa’s genius was using the tetrahedron because it has the smallest number of faces of any regular polyhedron. By mapping the Earth onto these four large triangles, he minimized the "seams" that usually tear through oceans or continents.
It’s worth noting that even Narukawa admits it isn’t perfect. No flat map is. But for a globalized society, it’s a massive step forward in spatial honesty.
Why Isn't Everyone Using It?
Habit is a powerful thing. We are conditioned to see the world a certain way. If you show the AuthaGraph projection world map to a room full of students, they might struggle to find their own country. The orientation is "tilted." The Atlantic Ocean looks different. The Pacific is no longer a vast emptiness on the edges.
Also, it’s hard to print. Most maps are standard rectangles that fit neatly in books. While the AuthaGraph is a rectangle, the way it "tiles" requires a bit of mental gymnastics. It hasn't been adopted by Google Maps because web-based maps rely on a variation of Mercator (Web Mercator) for seamless zooming and 90-degree corners.
Seeing the "Big Picture" Differently
One of the coolest things about this map is how it handles the "World's End." On a standard map, you get the impression that the world ends at the Bering Strait or the middle of the Atlantic.
Because the AuthaGraph can be tiled, you can shift the frame. You can place the focus on the "Great Circle" routes that satellites and long-haul flights actually take. This reveals things like the "Pacific Ring of Fire" or the flow of ocean currents in a way that feels like a single, connected system rather than a fragmented series of islands.

Actionable Steps for Exploring Your World
If you're tired of the distortions of 16th-century navigation charts, here is how you can actually use this knowledge:
- Get a physical AuthaGraph kit: You can buy paper models that you fold from a sphere into a tetrahedron and then into a flat map. It’s the best way to understand the geometry.
- Use it for Climate Data: If you are a teacher or a data visualizer, use the AuthaGraph to show things like sea-level rise or polar melting. It’s the only projection that doesn't minimize the impact at the poles.
- Audit your bias: Look at a Mercator map and then an AuthaGraph side-by-side. Focus on the size of India versus the UK, or Africa versus North America. It’s a quick way to "decolonize" your sense of geography.
- Explore the "Tessellation": Search for the AuthaGraph tiled view online. It allows you to see the Earth as a continuous surface without edges, which is a far more accurate representation of how our planet exists in the vacuum of space.
The world isn't a flat square with Europe in the middle. It’s a complex, beautiful, and tightly connected sphere. It’s about time our maps started acting like it.
