Project Sora

Sakurai launched Masahiro Sakurai on Creating Games, a YouTube channel in both English and Japanese in August 2022. The channel hosts educational content focused on game development and design, as well as Sakurai's career. Sakurai stated that he created the channel out of a desire to reach more people with his lessons, as he had previously been asked to give lectures on game design at schools. Sakurai additionally noted that other educational venues for game developers, such as the Game Developers Conference, focused on more advanced, technical details rather than more basic principles.

Sakurai began work on the channel immediately after the release of Sora in Super Smash Bros. Ultimate in October 2021. Sakurai wrote and recorded all 256 of the channel's videos himself before beginning work on Kirby Air Riders in April 2022, and contracted Hike Inc. for editing and 8-4 for English localization. The opening and ending jingles for the channel were composed by Yuzo Koshiro. Sakurai estimated that the total production cost of the channel was ¥90,000,000, which he paid entirely out of pocket, as he chose not to monetize the channel and did not receive any income from it.

Less than a day after its launch, the English edition of his channel gained over 200,000 subscribers. In 2023, the Computer Entertainment Supplier's Association announced that Sakurai had won the Game Design and Visual Arts awards for his channel. The association cited his efforts to share his knowledge in an easily understood manner. In March 2025, Sakurai announced that he had been listed as a recipient of the Agency for Cultural Affairs' annual Art Encouragement Prize for New Artists for his work on his channel.
