Game Studio Inc. is the Japanese developer of Echoes of Aincrad. The game is being published by Bandai Namco Entertainment.
Relationship to Earlier SAO Games
Previous Sword Art Online games set in the Aincrad arc (such as Infinity Moment, Hollow Fragment, and Hollow Realization) were developed by Aquria. Echoes of Aincrad is being developed by a different studio, Game Studio Inc., so the game's underlying engineering and design leadership are distinct from those earlier releases.
Studio Profile
Game Studio Inc. is a Tokyo-based Japanese game development company and a subsidiary of NJ Holdings. The studio has a long track record of work-for-hire development on titles for several major Japanese publishers, with a particular concentration of credits on action-oriented projects. The current assignment, this entry in the Sword Art Online series, sees the studio building a single-player action role-playing game on top of the in-fiction trapped-MMO setting of Aincrad. The studio's role is the underlying engineering, design, and content production for the title, while series-level production and publishing sit on the publisher side.
The exact ward of Tokyo at which the studio is headquartered is not consistently reported across primary sources, so this article keeps the location at the city level rather than committing to a specific ward. Likewise, specific staffing figures and capital values that show up on third-party aggregator pages are not echoed by the studio's own first-party material at the time of writing, so this article does not list a headcount, a capitalization figure, or a ward-level address.
Recent and Relevant Action-RPG Credits
Two of the studio's most recent credits are directly relevant to its current assignment, both being action role-playing games released within the last few years. They are the closest reference points the studio has shipped for the kind of single-player action RPG framing the current Sword Art Online entry is being built around.
Synduality: Echo of Ada (2025), a third-person action role-playing game with mech-pilot and survival systems built on top of a single-player campaign structure.
Infinity Strash: Dragon Quest The Adventure of Dai (2023), an arcade-style action role-playing game adaptation of the Dragon Quest: The Adventure of Dai property, with stage-based combat and party-switching mechanics.
Both titles share the broad shape of the studio's current work: a single-player action RPG with a customizable or party-based combat layer, story-driven content, and moment-to-moment combat as the central loop. The current Sword Art Online project sits in the same overall genre and production lane, which is consistent with the studio's recent direction.
Wider Catalog
Beyond those two recent credits, the studio's wider catalog spans several decades of Japanese game development across handheld, console, and mobile platforms. The list below names confirmed prior projects by title only. It is not exhaustive, and it deliberately omits attribution to any publisher because the focus here is on the development house rather than on who shipped each title.
The Ao Oni horror series, on multiple platforms.
Hopping Mappy (1986), an arcade-era platformer.
Mobile Suit Z Gundam: Hot Scramble (1986), an action title released for the Famicom generation.
Several Wizardry ports for the Famicom and Nintendo Entertainment System era of the role-playing-game genre.
The Tower of Druaga, on the TurboGrafx-16 generation, an action role-playing dungeon crawler.
Okamiden (2010), the Nintendo DS sequel to the original Okami action-adventure game.
Dragon Quest of the Stars, a long-running mobile entry in the Dragon Quest franchise.
LovePlus Every, a mobile reboot of the LovePlus dating-sim series.
Cardfight Vanguard Zero, a mobile take on the Cardfight Vanguard collectible card game.
Undergrounded, a personal-computer release in the studio's more recent slate.
Kingdom Hearts Missing-Link, a mobile spin-off of the Kingdom Hearts franchise, was also a Game Studio Inc. project. That title was canceled before its full launch, so it does not sit in the live catalog the way the entries above do, but it is a notable part of the studio's recent history and is worth recording for completeness.
First Sword Art Online Title
The current project is the first Sword Art Online title that Game Studio Inc. has developed. None of the prior Sword Art Online video-game releases were built at this studio, so the engineering, design leadership, and tooling for the current game come fresh to the franchise rather than carrying over from the codebase of an earlier entry. That is one of the differences in the current entry's underlying make-up that the article on the broader project picks up on the editions and pre-order bonuses page and on the high-level overview article.
Sword Art Online Franchise Developer Disambiguation
Because the franchise has had several different development partners over the years, it is worth laying out which studio handled which prior title. The current project is genuinely the first Sword Art Online video game to be made outside the rotation of three studios that have carried the franchise to date.
Aquria developed Sword Art Online: Infinity Moment for handheld in 2013, Sword Art Online: Hollow Fragment in 2014, Sword Art Online: Hollow Realization in 2016, Sword Art Online: Alicization Lycoris in 2020, and Sword Art Online: Last Recollection in 2023.
Artdink developed Sword Art Online: Lost Song in 2015.
Dimps developed Sword Art Online: Fatal Bullet in 2018 and Sword Art Online: Fractured Daydream in 2024.
The current entry is therefore the first Sword Art Online video game outside the Aquria, Artdink, and Dimps rotation. That matters in two practical ways. First, the codebase, tooling, and design leadership for the current title are distinct from the prior games in the series, so combat feel, traversal, and partner systems are a fresh design pass rather than an iteration on a known engine. Second, the prior Aincrad-arc entries from the Aquria-built side of the lineup, which the existing intro paragraph already names, are different studios' projects, so cross-references and comparison points to those games should be framed as franchise context rather than as the same team's earlier work.
There is also a separate company called Mobile and Game Studio. That entity is not the same as Game Studio Inc., and it should not be folded into this article when readers are tracing the studio's catalog or reading about the studio's lineage.
Lineage Note
The modern Game Studio Inc. has roots in Japanese game development that go back several decades. Some sources tie the current company to an older 1985-era entity founded by a former employee of a Tokyo arcade and console publisher, and other sources frame the modern company as a 2004-era entity that was standardized under its current name in the mid-2010s. The corporate continuity between the older entity and the modern company is not perfectly clear in primary English-language material, so this article does not commit to a single, clean 1985-to-present timeline.
What can be said with confidence is that the studio has been active in Japanese game development for a long time, that the modern company is a subsidiary of NJ Holdings, and that the studio's catalog stretches back well past the current console generation. Readers who are mainly interested in the studio's most recent work should focus on the action-RPG credits and the wider catalog sections above; the deeper question of when and how the company first incorporated is best left to a primary corporate disclosure rather than to this wiki page.
Production Roles on This Game
Two named production roles for the current project have been broken out in coverage, with one anchored to the development side and one anchored to the publisher side.
Yasuhiro Yahata is named as head of production for this game. The role is framed as the on-the-ground production lead for this specific title, anchored to the development side of the project rather than to the franchise office.
Yosuke Futami is the series producer for the franchise as a whole and is the producer credited on this game alongside the head-of-production role above. That role sits on the publisher side and across the broader franchise rather than inside the studio. It is mentioned here for completeness so that readers tracing credits do not assume Futami is a studio employee.
The game is being built on Unreal Engine 5, which is the engine the studio is using to produce the title's environments, character models, and combat systems. This is a different technical stack from the engines used on the prior Sword Art Online games, which is consistent with the rest of the project being a fresh design pass rather than an iteration on the older entries. For the player-facing combat layer that engine is being used to produce, see the combat system article.
What is Not Listed Here
A small number of details that sometimes appear on third-party aggregator pages have been deliberately left out of this article because they are not corroborated by primary first-party material. The list is recorded here so that future updates do not re-introduce them without a primary source to back them up.
A specific employee headcount for the studio.
A specific capital figure for the studio.
A specific ward of Tokyo for the studio's headquarters.
A clean, single-line founding date that bridges the older 1985-era entity and the modern company.
Names of internal team members beyond the head of production, since coverage has not broken out a public-facing roster of leads on this title at the studio level.
