It’s 1986. You’ve just beaten the original Super Mario Bros. and you’re hungry for more. You pop in the sequel, expecting a fun romp through the Mushroom Kingdom, but instead, the game punches you in the face. Repeatedly. This was the reality for Japanese players who picked up Super Mario Bros 2 Japan on the Famicom Disk System. It wasn't the whimsical, vegetable-tossing adventure we got in the West. It was a brutal, punishing, and frankly masochistic expansion pack that nearly broke the spirit of a generation.
Most people today know it as The Lost Levels. But back then? It was just the "real" sequel. Nintendo of America looked at it, saw the Poison Mushrooms and the wind gusts that blew Mario off tiny platforms, and basically said, "No thanks, our players will hate this." They weren't wrong.

Why Super Mario Bros 2 Japan is Basically a Prank
Honestly, playing this game feels like being bullied by a level designer. Shigeru Miyamoto and Takashi Tezuka didn't just want to make more levels; they wanted to challenge the "experts." Since the first game was a global phenomenon, they assumed everyone was already a pro. They were mistaken.
The game introduced the Poison Mushroom. For the first time, a power-up could actually kill you. It looked slightly different—darker spots, a bit of a meaner face—but in the heat of a jump, it was easy to snag it and die instantly. It was a psychological trick. Then there were the Red Piranha Plants. These things didn't care if you were standing next to the pipe. They’d come out anyway. In the original game, you could "suppress" a plant by standing on its pipe. Not here. You were never safe.
The Physics of Frustration
Nintendo also decided to differentiate Mario and Luigi for the first time in a meaningful way. In the first game, Luigi was just a green Mario. In Super Mario Bros 2 Japan, Luigi jumps higher but has almost zero friction. It’s like he’s wearing buttered shoes on a skating rink. Controlling him requires a level of precision that felt alien in 1986. You’d land a jump perfectly, only for Luigi to slide gracefully into a bottomless pit.
And let’s talk about the wind. Some levels have a literal gale-force wind blowing across the screen. You have to time your jumps so the wind carries you across massive gaps, but if you jump at the wrong microsecond, you’re tossed backwards or plummeted into the abyss. It turned a platformer into a physics puzzle from hell.
The Secret History of the Swap
You've probably heard the story of Doki Doki Panic. If not, here’s the gist: Nintendo of America thought the Japanese sequel was too hard and looked too much like the first game. They wanted something "new." So, they took a completely different game—Yume Kōjō: Doki Doki Panic—and slapped Mario’s face on the characters.
- Mario replaced the brother, Imajin.
- Peach replaced the mother, Mama.
- Toad replaced the strongman, Papa.
- Luigi replaced the tall, leggy sister, Lina.
This is why the Western version of Mario 2 has Birdo, Shy Guys, and Bob-ombs. None of those characters were originally Mario characters! They were guests who ended up staying forever. Meanwhile, the actual Super Mario Bros 2 Japan sat in a vault, unreleased in the West for years until the Super Mario All-Stars collection on the SNES gave us The Lost Levels.
Is It Actually a Bad Game?
It depends on who you ask. If you value "fairness," then yes, it's pretty bad. There are "Warp Zones" that actually send you backward to earlier worlds. It’s a total troll move. Imagine spending an hour fighting through World 3 only to get warped back to World 1. It's soul-crushing.
But for the speedrunning community and hardcore retro fans, Super Mario Bros 2 Japan is a masterpiece of tight design. It demands perfection. You can’t just "play" it; you have to master it. It’s the Dark Souls of the 8-bit era. It forces you to use mechanics you didn't even know existed, like the "frame-perfect" jump from the very edge of a block or using a Koopa Paratroopa as a mid-air stepping stone to clear a gap that's technically too wide to jump across.
The Mystery of World 9 and Beyond
Most Mario games end at World 8-4. If you managed to beat Super Mario Bros 2 Japan without using a single Warp Zone, you were gifted with World 9. It was a bizarre, glitchy-looking "fantasy" world where the water was above ground and the ground was made of Bowser's castle bricks.
And if you beat the game eight times? Yes, eight. The title screen would sprout little stars. Once you hit eight stars, you could access Worlds A, B, C, and D. These were the true final challenges. World D-4 is a gauntlet that makes the rest of the game look like a tutorial. It’s a badge of honor for any Nintendo fan to say they’ve cleared it on original hardware.
How to Experience it Today
If you want to try it, don't go hunting for a Famicom Disk System unless you’re a serious collector. The easiest way is through Nintendo Switch Online. It’s listed as Super Mario Bros.: The Lost Levels.
A quick tip for the brave:
- Play as Luigi first. His high jump is a literal lifesaver, even if he slides around.
- Watch out for the "squiggled" clouds; they often mark hidden blocks.
- Never, ever trust a Warp Zone unless you’ve looked it up first.
- Use the "Suspending Point" (Save State) feature on the Switch. The original players didn't have it, but they also didn't have lives to lose anymore after the first ten minutes.
The legacy of Super Mario Bros 2 Japan is one of the most interesting "what-ifs" in gaming history. If Nintendo had released this in America in 1987, would Mario still be the king of gaming? Or would kids have thrown their controllers at the TV and moved on to the SEGA Master System? We’ll never know. What we do know is that it remains a fascinating, frustrating, and incredibly rewarding piece of history that every Mario fan should try—at least once.
Your Next Steps
If you're ready to tackle this beast, start by loading up the NES library on your Switch and look for The Lost Levels. Don't try to speedrun it on your first go. Just try to survive World 1-1. If you find yourself getting frustrated, remember that even the experts at Nintendo thought this was "too much" for us. There's no shame in using a save state after a particularly brutal jump. Once you've cleared the first few worlds, look up a map of World 9 to see what you're aiming for. It's a weird, wonderful trip into Nintendo's experimental phase that you won't find anywhere else in the franchise.
