There were two different games called Super Mario Bros. 2. In Japan, the title referred to a challenging sequel to the original. In the West, Nintendo instead released a Mario-character adaptation of Yume Kōjō: Doki Doki Panic. That regional adaptation is the game most Western players know as Super Mario Bros. 2; Nintendo later released it in Japan as Super Mario Bros. USA.
Why are there two different Super Mario Bros. 2 games?
The name depends on the region. Japan’s Super Mario Bros. 2 was a direct follow-up to the first game, with familiar play and a much higher difficulty. Nintendo released that game outside Japan later as Super Mario Bros.: The Lost Levels.

The Western Super Mario Bros. 2 was a different title: Nintendo adapted the Japanese game Yume Kōjō: Doki Doki Panic, replacing its characters with Mario characters. So the “swap” was a regional release decision, not a case of Nintendo turning the two games into one sequel. Nintendo’s official Iwata Asks archive identifies the games and their release dates.

What was the Western game originally?
Doki Doki Panic was an action game made with Fuji Television in connection with Yume Kōjō, or “Dream Factory.” Nintendo’s archive dates its Japanese release for the Famicom Disk System to July 1987. WIRED reports that Nintendo was asked to build a game around characters associated with the event.
#1 Best Overall
When adapting it for Western players, Nintendo used Mario, Luigi, Princess Peach and Toad in place of the original cast. The adapted game later reached Japan under the name Super Mario Bros. USA, released there in September 1992, according to Nintendo’s archive.
How did its unusual gameplay develop?
In a 2011 WIRED interview-based report, director Kensuke Tanabe recalled an early prototype built around vertical climbing for two players. Players could stack blocks or throw one another upward. Tanabe said, “the vertical-scrolling gimmick wasn’t enough to get us interesting gameplay.” Shigeru Miyamoto encouraged the team to move toward a more conventional side-scrolling game.

Tanabe connected actions from that prototype—lifting objects and throwing characters—to the finished game’s emphasis on picking up and throwing enemies and objects. This account comes from Tanabe’s recollection as reported by WIRED, rather than a surviving design document. The report also attributes to him the observation: “We knew these Fuji TV characters wouldn’t be popular in America, but what would be attractive in America would be the Mario characters.”
What makes the Western Super Mario Bros. 2 play differently?
The first Super Mario Bros. is strongly associated with jumping on enemies. In the Western sequel, picking up and throwing enemies and objects is central to play, giving it a distinct action pattern rather than simply repeating the original game’s approach.
Rank #3
- This renewed game will not come with the original case or manual; cartridge only. It has been cleaned, tested, and is in nice condition.
Players can also choose among characters with different handling. Nintendo Life notes that Luigi jumps higher and Peach descends more slowly. Those differences reflect traits associated with the original Doki Doki Panic cast, retained when Nintendo adapted the game for Mario.
How the regional releases fit together
| Region and name | What the game is | Relationship to the first game | Release detail established by sources |
|---|---|---|---|
| Japan: Super Mario Bros. 2 | A distinct Japanese sequel; later released in the West as The Lost Levels. | A direct follow-up with familiar mechanics and substantially higher difficulty. | Nintendo’s archive identifies it as a separate game; no date is needed to distinguish it here. |
| West: Super Mario Bros. 2 | A Mario-character adaptation of Yume Kōjō: Doki Doki Panic. | Different from the Japanese sequel, with selectable characters and a focus on lifting and throwing. | WIRED describes the Western game’s 1988 arrival as a hit, without giving a numerical sales total. |
| Japan: Super Mario Bros. USA | The adapted Doki Doki Panic game known in the West as Super Mario Bros. 2. | The same adaptation, released under a Japanese title that distinguishes it from Japan’s earlier sequel. | Nintendo’s archive gives September 1992 as its Japanese release. |
Why the distinction matters
Asking why Super Mario Bros. 2 feels unlike the first game has a straightforward answer: Western players received an adaptation of a different Japanese game, not the Japanese sequel. The adaptation’s character selection and pick-up-and-throw mechanics gave it an identity of its own, while Japan’s original sequel remained a separate title later known internationally as The Lost Levels.
