It is one of the most famous identity crises in the history of software. Ask any millennial or Gen X gamer about when did Super Mario Bros 2 come out, and you might get two different answers depending on whether they grew up in Tokyo or Toledo. It’s weird. Most sequels follow a linear path, but Nintendo decided to take a sharp left turn in the late eighties that still confuses people today.
The short answer is October 9, 1988. That is the day the North American version hit shelves. But if you were a kid in Japan, you’d been playing a completely different "Super Mario Bros. 2" since June 3, 1986.
Essentially, we didn't get the same game. Not even close.
The 1986 Japanese Original: Too Hard for Humans?
After the massive success of the original NES title, Shigeru Miyamoto and his team at Nintendo R&D4 went to work on a follow-up. They released it on the Famicom Disk System. It looked almost exactly like the first game, but with one major difference: it was brutally, soul-crushingly difficult.
It featured Poison Mushrooms that could kill you. It had wind gusts that blew you off platforms. It even had "Warp Zones" that sent you back to earlier worlds instead of forward. It was basically a ROM hack before ROM hacks were a thing. When Howard Lincoln and the team at Nintendo of America saw it, they reportedly thought it was too frustrating for the burgeoning US market. They worried it would kill the momentum of the NES.
So, they shelved it. They needed a "sequel" for America, but they didn't want that one.

The 1988 American Pivot: Enter Doki Doki Panic
This is where the story gets really bizarre. Since Nintendo of America rejected the "real" sequel, the company had to find a replacement. They looked at a game called Yume Kōjō: Doki Doki Panic, which was a promotional title developed for the Fuji Television "Dream Factory" expo.
Doki Doki Panic wasn't a Mario game. It featured an Arabian-themed family—Papa, Mama, Imajin, and Lina—who had to rescue children from a dream world. The mechanics were totally different from Mario. You didn't stomp on enemies; you plucked vegetables out of the ground and threw them.
Nintendo basically "Mario-fied" it. They swapped the family members for Mario, Luigi, Peach, and Toad. They added some animations, changed the sound effects, and slapped the title Super Mario Bros. 2 on the box.
When the game finally launched in the US in October 1988, it was a massive hit. It sold about 10 million copies. Players loved the ability to pick different characters with unique stats—like Luigi’s high jump or Peach’s floaty hover. Nobody in the States knew they were playing a reskinned Japanese game about a dream festival. They just knew it was fun.
The Lost Levels and the Great Reconciliation
For years, the "real" Japanese sequel remained a mystery to Western audiences. It wasn't until 1993, with the release of Super Mario All-Stars on the SNES, that we finally got to see it. Nintendo rebranded the 1986 Japanese game as Super Mario Bros.: The Lost Levels.

Suddenly, the timeline made sense.
Honestly, the "fake" Mario 2 (the American one) actually had a much bigger impact on the franchise's DNA than the Japanese one did. Think about it. Shy Guys, Birdo, Bob-ombs, and Pokeys all debuted in the American Super Mario Bros. 2. If Nintendo hadn't made that weird decision to reskin Doki Doki Panic, those iconic characters might not exist in the Mario universe today. Even the way Luigi looks—tall and lanky—started here because he was swapped with the "Mama" character from the original Japanese game.
A Timeline of the Madness
To keep the dates straight, you have to look at the regions separately. It’s a mess of re-releases and porting.
- June 3, 1986: Japan gets the "True" Super Mario Bros. 2 on the Famicom Disk System. It’s the one with the Poison Mushrooms.
- July 10, 1987: Japan gets Yume Kōjō: Doki Doki Panic, the non-Mario game that would later become the US sequel.
- October 9, 1988: North America finally sees when did Super Mario Bros 2 come out for the NES. This is the reskinned version.
- April 28, 1989: The American version is released in Europe.
- September 14, 1992: Japan finally gets the American version, released there under the title Super Mario USA.
The confusion didn't end in the eighties. Nintendo kept re-releasing these games on every console imaginable. You had the Game Boy Advance version (Super Mario Advance) in 2001, which added a giant health-bar-stealing boss named Robirdo. Then you had the Virtual Console releases on the Wii, Wii U, and 3DS.
Why the Delay Actually Helped Nintendo
If Nintendo of America had just released the Japanese version in 1986, the NES might have been seen as a "more of the same" console. By waiting until 1988 and using the Doki Doki Panic engine, they gave players something that felt radically fresh. It expanded what a platformer could be.

It also gave the developers time to work on Super Mario Bros. 3, which came out in Japan only a few weeks after the US got Mario 2. That’s the real kicker: while Americans were just starting to pluck turnips in late 1988, Japanese players were already exploring the World Map and wearing Tanooki suits in Mario 3.
Identifying Your Version
If you are trying to figure out which game you actually played, just look at the enemies. If you spent your childhood running away from a red dinosaur that spits eggs (Birdo) or trying to outrun a mask that follows you when you pick up a key (Phanto), you played the 1988 Western version.
If you remember a game that looked exactly like the original Mario but had a purple mushroom that killed you instantly, you played The Lost Levels.
Both are technically Super Mario Bros. 2. One is a masterpiece of subverted expectations, and the other is a masochistic test of patience.
Actionable Steps for Retrogamers
If you want to experience this history yourself, you don't need a dusty NES.
- Check Nintendo Switch Online: Both versions are currently available. The 1988 US version is under the NES library as Super Mario Bros. 2. The 1986 Japanese version is listed as Super Mario Bros.: The Lost Levels.
- Play them in order of release, not number: Try the original, then play The Lost Levels to see why American executives were scared of it. Then play the US Mario 2 to see the creative leap.
- Look for the differences: In the US version, play as Toad if you want speed, or Peach if you want to skip difficult platforming sections.
- Compare Super Mario USA: If you can find a Famicom import of Super Mario USA, it’s a fun way to see how Japan eventually embraced the "American" sequel.
Understanding the history of this release makes you realize that "canon" in video games is often just a byproduct of marketing decisions and regional anxieties. Nintendo didn't have a master plan; they just wanted to make sure kids didn't throw their controllers through their TV screens in 1988.
