Interview portrait
Koji Kondo is not a prolific public speaker. His interview material is relatively sparse compared to his compositional output - a reflection of Nintendo's traditionally reserved corporate culture and Kondo's own disposition. What exists, however, is revealing.
The primary sources are Nintendo's own Iwata Asks interview series, which features extended conversations between Nintendo President Satoru Iwata and key staff. The Super Mario Bros. 25th Anniversary edition (2010) and the Ocarina of Time 3D edition (2011) are the most substantial Kondo interview records publicly available.
Iwata Asks - Super Mario Bros. 25th Anniversary
Published in 2010 to mark the 25th anniversary of Super Mario Bros., this extended Iwata Asks conversation with Kondo, Miyamoto, Tezuka, and others is the most comprehensive primary source on the compositional process behind the SMB score. Source: Nintendo - Iwata Asks.
"Miyamoto-san told me that for the underground stages, he wanted music that felt cramped, like you were under pressure. For the overworld, he wanted something that felt open and free - like going outside to play. I started from those feelings, not from musical specifications."
- Koji Kondo, paraphrased from Iwata Asks: Super Mario Bros. 25th Anniversary (2010)
"I tried to make the music such that it would not be annoying after being heard many times. A player who keeps failing at the same level might hear the same theme dozens of times. It had to be bearable - more than bearable; it had to keep them feeling that they could try again."
- Koji Kondo, paraphrased from Iwata Asks: Super Mario Bros. 25th Anniversary (2010)
"I always had in mind how the player would feel at each moment. The music's purpose is not to show off what I can do - it is to support what the player is doing and how they feel."
- Koji Kondo, paraphrased from Iwata Asks: Super Mario Bros. 25th Anniversary (2010)
Iwata Asks - Ocarina of Time 3D
Published to accompany the Ocarina of Time 3D remake (2011), this Iwata Asks features Kondo and Eiji Aonuma discussing the original 1998 score, the Ocarina mechanic, and the collaborative composition process with Minegishi and Tanaka. Source: Nintendo - Iwata Asks.
"The Ocarina songs had to work as both gameplay and music. The player would play them themselves - pressing buttons in sequence - so they had to be simple enough to perform, yet satisfying enough as melodies to want to hear again and again."
- Koji Kondo, paraphrased from Iwata Asks: Ocarina of Time 3D (2011)
GDC and Public Talks
No confirmed standalone Koji Kondo GDC talk has been identified as of 2026. Kondo has appeared at E3 demonstrations and Nintendo Directs over the years, but his public speaking career is limited compared to his compositional prominence. A GDC 2010 Classic Game Postmortem panel referenced Super Mario Bros.; Kondo's direct participation in that session is unconfirmed.
The Iwata Asks series remains the primary venue where Kondo's compositional philosophy is expressed at length. For broader analysis of his work, the game music scholarship community - particularly the journal Journal of the Society for American Music and Video Game Music & Theory - has produced substantive academic work on the SMB and Zelda scores.
How Others Have Described the Work
"The Super Mario Bros. theme may be the first piece of video game music most people ever heard, and it remains among the finest examples of music serving its context - upbeat without being shallow, simple without being simplistic."
