Prope
independent video game studio
Prope Ltd. (株式会社プロペ, Kabushiki-gaisha Purope) is a Japanese video game developer based in Tokyo, founded in 2006 by Sonic the Hedgehog co-creator Yuji Naka upon his departure from Sega. Its name means "near" or "beside" in Latin.
Formation
As part of Sega's "support program for independent game creators", Yuji Naka left Sega to start his own studio, along with ten Sonic Team members. It had a starting capital of ¥10 million, 10% of which came from Sega in exchange for the right of first refusal for publishing his studio's games. Prope was founded on May 23, 2006 and began operations one week later, on June 1.
Prope intended to create games with a graphical style that appealed to both children and adults, and to explore the possibilities of developing both 3D and 2D games. Naka joined Square Enix in January 2018, leaving the status of Prope uncertain. In March 2019, Naka confirmed that Prope had been reduced to a one-person company since the end of April 2017.
Naka released SHOT2048 under the Prope brand in December 2021, his first game following his departure from Square Enix back in April.
This brief starts where responsible research should: with the source description of “Prope” as independent video game studio. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as independent video game studio. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q4047460. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006, 2018, 2019 and 2017.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
