Ask any tech expert who invented emojis, and they will tell you: Shigetaka Kurita, 1999, for the Japanese carrier NTT DoCoMo. It's a perfect, elegant, and widely documented story. There is just one problem: it isn't true.
Digital Archaeology Rewrites History
The official narrative collapsed in 2019 when the Unicode Consortium quietly corrected its historical records. The cause? A discovery made by digital culture researchers (including Matt Alt, author of "Pure Invention: How Japan Made the Modern World") who unearthed a forgotten technological "fossil": the J-Phone SkyWalker DP-211SW, released by SoftBank on November 1, 1997.
This device, launched two years before DoCoMo's famous i-mode, contained a set of 90 pictographic characters. They were crude, monochromatic, and tiny, but they were unmistakably emojis. They included:
- The first version of the Pile of Poo (💩), debunking the myth that it was created by Google in 2008.
- The Martini Glass (🍸) and the Broken Heart (💔).
- A spouting whale that appeared in promotional materials—one of the earliest emoji appearances in marketing history.
- Moon phases, weather icons, sports symbols, and zodiac signs.
The proof was hiding in plain sight: press releases, user manuals, and promotional photographs that had been gathering digital dust for over two decades. Matt Alt even purchased original device manuals to document the forgotten history pixel by pixel.
The SkyWalker DP-211SW: A Phone Ahead of Its Time
The DP-211SW was not just any phone. Manufactured by Pioneer for J-Phone (which would later become Vodafone Japan and eventually SoftBank Mobile), it was a minor revision of the DP-211, specifically designed to launch with J-Phone's new "Sky Walker" messaging service.
The device was advanced for its time, with a liquid crystal display capable of rendering detailed kanji characters—and those 90 emoji pictographs, each drawn in a 12x12 pixel monochrome grid.
According to InternetWatch archives, the price was steep: 52,000 yen for the device alone (roughly $430 at 1997 exchange rates), or 64,000 yen for the standard set including battery pack and charger. The Sky Walker service itself charged 5 yen per message, plus a separate monthly fee of 1,000 yen for internet email access.
The software manual, rediscovered by researchers, clearly shows the emoji picker interface with all 90 characters available. Numbers, sports, time indicators, moon phases, weather symbols—and yes, that smiling pile of poo.
Why Was 1997 Forgotten?
If SoftBank came first, why does Kurita get all the credit? The answer lies in a cruel combination of commercial failure and technological isolation.
The DP-211SW was expensive in a market where consumers expected carrier subsidies. The Sky Walker network was spotty. But the fatal flaw was simpler: the emojis only worked between devices of the exact same model. Send a 💩 to someone with a different phone—even a different J-Phone model—and they'd receive gibberish or nothing at all.
Without critical mass, a language cannot spread. The DP-211SW became a footnote, remembered only by collectors and the engineers who built it.
In contrast, DoCoMo's i-mode platform launched on February 22, 1999, as the world's first mass-market mobile internet service. It wasn't just a phone feature—it was an ecosystem. I-mode allowed text-only web browsing, email, train schedule checking, ticket booking, and commerce. By 2008, it had accumulated 50 million users in Japan alone.
When Shigetaka Kurita designed his 176 emoji for i-mode, they weren't trapped on one device model. They worked across the entire DoCoMo network, on every i-mode compatible phone. Millions of Japanese teenagers adopted them overnight. History, as they say, is written by the winners.
"Innovation doesn't matter if no one uses it. SoftBank invented the wheel, but DoCoMo built the roads."
The Galapagos Effect
There's a Japanese term that explains why these early emoji sets remained unknown to the world for so long: Garapagosu-ka—"Galapagosization."
Just as Darwin's finches evolved in isolation on the Galapagos Islands, Japanese mobile technology developed its own unique ecosystem completely disconnected from the rest of the world. By the late 1990s, Japanese keitai (携帯, mobile phones) could browse the internet, send picture messages, watch TV, and make mobile payments—features that wouldn't reach Western phones for another decade.
But each Japanese carrier built proprietary systems incompatible with competitors. DoCoMo had i-mode. KDDI had EZWeb. J-Phone/Vodafone had J-Sky. The same emoji code point could display a convenience store on one carrier and a wristwatch on another. Even within Japan, cross-carrier emoji communication was a nightmare until server-side conversion services emerged years later.
For international markets? Forget it. Japanese emoji were as exportable as Japanese electrical outlets—technically functional, but useless anywhere else.
This isolation explains why the world only learned about emoji when Apple and Google forced standardization through Unicode in 2010. And by then, everyone had forgotten about a touchscreen phone from 1997 that nobody bought.
The Aesthetics of 12x12: Art in a Prison Cell
What makes the SoftBank 1997 set fascinating today is the brutal economy of its design. Those anonymous J-Phone engineers had a grid of only 12x12 pixels—144 dots total—in black and white. Every single pixel counted.
Compare this to Kurita's DoCoMo set two years later: same 12x12 grid, same constraints, but with color. Kurita later admitted he hated the even-numbered grid: "Not being able to find a center made developing the emoji extremely laborious." With 12 pixels per side, there's no true center point—every symmetrical design is a compromise.
Yet both teams arrived at similar solutions. The SoftBank set tried to be illustrative—tiny drawings of objects. Kurita's approach was more iconic—symbols representing concepts rather than pictures representing things. It's a subtle philosophical distinction, but it may explain why Kurita's designs felt more universal: they were signage, not art.
The SoftBank whale, the moon phases, the sports equipment—these were attempts to compress reality into 144 dots. Kurita's hearts, his weather symbols, his expressive faces—these were attempts to compress meaning into 144 dots. Both succeeded. But meaning travels better than pictures.
Even Earlier: The 1988 Discovery
As if the 1997 revelation wasn't enough, digital archaeologist Matt Sephton (known online as @gingerbeardman) pushed the timeline back even further in 2024. While researching vintage Japanese drawing software, he discovered emoji-like character sets in Sharp personal digital assistants from the late 1980s.
The Sharp PA-8500, released in October 1988, contained over 100 pictographic characters at 16x16 pixels—larger and theoretically more detailed than the later mobile phone emoji. Smiling faces, animals, weather symbols, zodiac signs. The designs were clearly ancestral to the SoftBank set that would appear nine years later.
But these PDA emoji existed in an even smaller bubble than the DP-211SW. Sharp's devices were niche products for Japanese professionals, not mass-market consumer phones. They represent the evolutionary ancestors of emoji—the proto-mammals that would eventually give rise to the digital language we use today.
Sephton's research established a clearer timeline: Sharp PA-8500 (1988) → NEC PI-ET1 (1990) → Sharp Zaurus series (1993-1995) → J-Phone DP-211SW (1997) → DoCoMo i-mode (1999). Emoji didn't spring from Kurita's mind fully formed. They evolved across a decade of Japanese devices that the world never saw.
The Poo That Started It All
One emoji deserves special attention: 💩. The Pile of Poo appeared in the SoftBank 1997 set—smiling, steaming, unmistakable—two years before Kurita's DoCoMo set (which didn't include it; corporate executives reportedly said "no good").
Why would Japanese engineers put feces in a phone? Because in Japan, poop is lucky. The word unko (うんこ) shares its opening sound with un (運, luck). Golden poop charms called Kin no Unko are popular good luck tokens. The manga Dr. Slump (1980-1984) by Akira Toriyama normalized cute, anthropomorphic poop in Japanese pop culture years before anyone thought to digitize it.
The SoftBank poo was simple: a coiled shape with a smile and steam lines. It would take Google's 2008 Gmail implementation—complete with animated flies—to bring poop to Western audiences, and Apple's kawaii redesign to make it universally beloved. But Patient Zero was born in 1997, on a phone that nobody bought, designed by engineers whose names are lost to history.
The Lost Legacy Restored
The next time you send an emoji, you are using the direct descendants of that 12x12 grid from November 1, 1997. Although today our icons are rendered in high-definition 3D with millions of colors, the structural DNA remains the same: faces made of dots, hearts that mean love, weather that means weather.
Acknowledging SoftBank's primacy takes nothing away from Kurita's genius. He made emoji a mass phenomenon. He understood that emoji were signage for emotions, not miniature art. His work at DoCoMo created the cultural moment that eventually led to global adoption.
But historical justice demands that we remember those anonymous engineers at J-Phone who, on November 1, 1997, shipped a phone containing 90 tiny pictographs—including a smiling pile of poo—and changed communication forever, even if nobody noticed for twenty years.
Porto Rebaix wrote in 2017: "It is just a question of time that the designers of the SkyWalker Emojis and the developers behind this innovative mobile phone ahead of its time receive a well-deserved recognition." That time has come.
The SkyWalker DP-211SW failed commercially. Its emojis couldn't escape a single phone model. But somewhere in an archive, a press release photograph shows a tiny spouting whale on a screen—one of the earliest emoji ever displayed to the public.
History is written by the winners. But sometimes archaeologists dig up what the winners forgot.
