Down the Parhole: Shipyards, Gold Leaf, and the Silent Grandparent

A Skyline Built on a Shipyard

The address on the scanner manual reads i-MARK PLACE, Minatomirai, Yokohama. It sounds like nothing, a corporate park, the sort of place you would never think about twice. But Minatomirai is one of the strangest and most deliberate pieces of city ever built, and the name itself is a promise. It means, roughly, harbor of the future. Someone looked at a stretch of working waterfront and decided to build tomorrow on top of it.

Because what stood there before was a shipyard. This was heavy industry, the docks and slipways of Mitsubishi, where enormous steel ships were welded together by the noise and fire of postwar Japan. And then, in the nineteen eighties, Japan decided to do something audacious: to take this gritty industrial harbor and reclaim it, partly from the sea itself, and raise in its place a gleaming district of glass towers, convention halls, and a skyline meant to look like science fiction. They built the Landmark Tower, which for years stood as the tallest building in all of Japan. They put up a giant ferris wheel with a clock built into its face, turning slowly over the water. A shipyard became a postcard of the future, and a scanner company keeps its polished headquarters there. The beige boxes are designed in a place that used to launch battleships.

The Town That Hides in a Letter

Now travel to the opposite end of the company, and the opposite end of Japan. Remember the U in PFU, the one that stands for Unoke. That is a real place, a small town now part of the city of Kahoku, sitting on the coast of Ishikawa Prefecture, facing the cold gray Sea of Japan. This is snow country. Winters here are heavy and quiet. It is about as far from the glass towers of Minatomirai as a place in Japan can feel, and it is where this whole scanner empire actually grew its roots back in nineteen sixty.

But the town hides next to something extraordinary, because just down the coast sits Kanazawa, one of the most beautiful cities in Japan, and one of the luckiest. Kanazawa was a great castle town of the old feudal lords, and it almost entirely escaped the bombing of the Second World War, which means its samurai districts, its geisha quarters, and its old wooden streets survived intact when so much of Japan burned. At its heart is Kenrokuen, considered one of the three great landscape gardens of the entire country, a place designed across centuries to be perfect in every season.

And Kanazawa has a peculiar specialty that I cannot resist telling you about. It makes gold leaf. Almost all of Japan's gold leaf, the gossamer-thin sheets of hammered gold used to decorate temples, lacquerware, and screens, comes from this one city, because its humid, still climate happens to be ideal for beating gold into a film thinner than a thought. They take it so seriously that you can buy ice cream there wrapped entirely in a sheet of edible gold, a soft-serve cone glittering like treasure. So the unglamorous town that hides inside a scanner's name sits next door to a preserved feudal city that beats gold into ghosts and serves it on dessert. I should add, gently, that this coast has known hardship too, and the wider Noto region north of here has had hard recent years, which the people of Ishikawa carry with the same quiet endurance the place has always asked of them.

The Silent Grandparent

Now for the reveal this whole series has been building toward, the thread that ties the accidental family together. Across these episodes, one name kept surfacing in the background, attached to two completely different giants. Riken. The national Institute of Physical and Chemical Research.

[serious] Riken is real, and it is old. It was founded in nineteen seventeen as Japan's great national laboratory for the physical and chemical sciences, and it has been a powerhouse of Japanese research for more than a century, home over the years to Nobel laureates and to discoveries that range from the fundamental to the industrial. But Riken did something unusual for a research institute. It became an engine of companies. It spun its science out into the world as real businesses, a whole constellation of firms that grew from its laboratories, sometimes called the Riken group or the Riken concern.

And two of those threads run straight through our story. At the very beginning, in nineteen thirty-six, it was Riken's commercial arm that spun off the little sensitized paper company that became Ricoh. The name Ricoh is an echo of Riken. And then, eighty-four years later, in twenty twenty, it was Riken that partnered with Fujitsu to build Fugaku, the fastest supercomputer in the world at the time, which sits in a Riken facility in Kobe. So the same institution stood at the birth of one giant and at the technological summit of another. A single quiet laboratory, founded in nineteen seventeen, is the secret grandparent of both the paper company and the supercomputer. Most people have never heard its name, and it helped father the whole family.

Sidequests With No Through-Line

And now, because the brief for this episode was explicitly to wander, let me give you a few rabbit holes that connect to nothing, because sometimes the tangent is the entire reward.

Sidequest one. The Happy Hacking Keyboard, the cult keyboard that PFU makes, was co-designed by a man named Eiti Wada, who was not some random product engineer. He was a serious computer scientist, a figure in the early history of computing and networking in Japan, the kind of person who thought deeply about the philosophy of how a human and a machine should touch each other through their fingertips. He believed a keyboard should be small, uncluttered, and built so that your hands barely have to move. The keyboard a chunk of the world's programmers worship was a philosopher's object, not a marketing one. It was designed by someone asking what typing should feel like, not what would sell.

Sidequest two, and it connects to absolutely nothing. The Sea of Japan, the cold water that Unoke looks out on, is the subject of a long and bitter naming dispute, with Korea preferring to call it the East Sea, a quarrel that has played out in international map committees and diplomatic letters for decades. A body of water can have a fight over its own name that outlasts entire governments. The town that hides in the U of PFU looks out every morning at a sea that cannot agree on what it is called.

[happy] And sidequest three, the one that closes the loop on the whole silly journey. We got here from three flat letters in the small print of a four hundred kronor used scanner. P, F, U. And following those letters led us to a shipyard turned into a city of the future, to a snowbound town beside a city that beats gold into edible ghosts, to a hundred-year-old physics laboratory that secretly fathered two technology giants, to a philosopher who designed the perfect keyboard, and to a sea that cannot settle its own name. None of it was on the box. None of it was the point of the purchase. The scanner just needed to digitize some paper.

But that is the whole pleasure of the rabbit hole, is it not. You go looking for a feed roller and a duty cycle, and you come out the other side holding a national laboratory, a feudal garden, and a German telephone switch from nineteen twenty-three, none of which you needed, all of which were hiding in plain sight, in the type you were never meant to read. The machine does the work. The wandering is the joy. And the small print, it turns out, always goes deeper than you think.
