About

Masahiro Sakurai is a Japanese game designer best known as the creator and director of the Super Smash Bros. series and the Kirby series. He directed Super Smash Bros. Melee (2001), which became the best-selling GameCube title and established the competitive fighting game community that persists to this day.

History

Masahiro Sakurai was born on August 3, 1970, in Musashimurayama, Tokyo. In 1989, at eighteen years old and fresh out of high school, he joined HAL Laboratory — a small game developer that had been supplying software to Nintendo since the Famicom era. Within a year, Sakurai had been assigned to create a new character and game concept. He was nineteen when he wrote the first proposal document for what would become Kirby's Dream Land. The game released in April 1992 on the Game Boy and sold over five million copies worldwide. For a company that had been teetering on the edge of bankruptcy, it was not an incremental success — it was rescue.

Kirby was designed as a deliberate inversion of contemporary arcade conventions. Where most games of the early 1990s punished mistakes harshly and demanded fluency from the first stage, Sakurai built Kirby to welcome beginners. The character could fly indefinitely. The controls were simple. Mistakes were forgiving. Beneath that surface accessibility, however, lay depth that rewarded skill — copy abilities, hidden rooms, score optimization. Sakurai's design philosophy was already visible in full: see things from the player's perspective, and never limit the possibilities of what a game can be.

The success of Kirby established Sakurai as a lead director at HAL Laboratory. He directed Kirby's Adventure (1993) and Kirby Super Star (1996), expanding the series while refining its core identity. Then, in 1998, he began work on an experimental fighting game prototype called Dragon King: The Fighting Game. The prototype had no licensed characters — it was a technical proof that four players could fight simultaneously on a three-dimensional stage. When Nintendo greenlit the project, Sakurai transformed it into Super Smash Bros., bringing together Mario, Pikachu, Link, and other Nintendo icons in a fighting game that felt nothing like Street Fighter or Tekken. It released in Japan in January 1999, sold over five million copies worldwide, and redefined what a platform fighter could be.

The sequel, Super Smash Bros. Melee, arrived in November 2001 on the GameCube. Sakurai directed it under brutal deadlines — the game had to launch alongside the console. The development schedule left no room for iteration. Yet Melee became the best-selling GameCube title and, two decades later, remains the center of a competitive fighting game community that never stopped playing it. Sakurai has said that the game's longevity came at a cost: the pace nearly destroyed him. He worked thirteen-month stretches without a single day off. He developed hand and wrist injuries that required treatment. When Melee shipped, he told himself he would never make another Smash Bros. game. Within two years, he was working on the next one.

In August 2003, Sakurai left HAL Laboratory. He did not leave because of conflict or failure — he left because he wanted freedom. HAL was part of the larger industry machine of sequels and safe franchises, and Sakurai, at thirty-two, wanted the ability to say no. In 2005, he founded Sora Ltd. with his wife, Michiko Sakurai, who had also worked at HAL. Sora was not a studio in the conventional sense. It employed only two people and developed nothing on its own. Instead, it served as a vehicle through which Sakurai could contract his services to other companies while retaining creative autonomy. He directed Super Smash Bros. Brawl (2008), Super Smash Bros. for Nintendo 3DS and Wii U (2014), and Super Smash Bros. Ultimate (2018) — each time as a freelance director, not as an employee.

Between Smash titles, Sakurai also directed the puzzle game Meteos (2005) and the 3DS title Kid Icarus: Uprising (2012). Uprising, in particular, reflected his philosophy of accessible depth: the controls were designed to be simple enough for newcomers, yet the game contained layers of customization, difficulty modes, and scoring systems that hardcore players could spend hundreds of hours exploring. Sakurai has said he does not particularly enjoy puzzle games, yet he made Meteos anyway — a testament to his belief that a designer must serve the player's needs, not their own preferences.

In August 2022, Sakurai launched a YouTube channel titled Masahiro Sakurai on Creating Games. Over the next two years, he uploaded 260 videos — most pre-recorded in a single intensive production period in late 2021, when a gap in his schedule allowed him to write 256 scripts totaling 300,000 words. The channel was never monetized. Production costs reached approximately 90 million yen. Sakurai funded it himself. The channel amassed over 62 million views in Japanese and over 20 million in English before concluding in October 2024. The purpose, he explained, was simple: to raise the quality of games worldwide, even by a small margin, by teaching the principles he had spent decades learning. He once said that making games is an act of stacking small stones one at a time — exhausting, painstaking, and fragile. But if it meant more people could enjoy the result, he would weather any hardship.

Sakurai's career is a study in contradictions that resolve only when viewed as a unified philosophy. He made games for beginners while being a hardcore player himself. He built franchises that millions loved, yet walked away from the security those franchises offered. He poured 90 million yen into educational videos that generated no revenue. The through-line is not ambition or branding — it is service. Sakurai has spent his entire life in service to an idea: that games should welcome everyone, challenge anyone willing to go deeper, and leave the world slightly better than it was before the cartridge was inserted. That is not an accident of talent. It is the result of choosing, again and again, to see things from the player's perspective — and refusing to limit what gameplay can become.
