ONE PIECE: Grand Gourmet Developer and Publisher Guide

Who Is Making ONE PIECE: Grand Gourmet?

Sanji’s next kitchen adventure has two company names worth knowing. The ONE PIECE: Grand Gourmet developer and publisher are Kairosoft Co., Ltd and Bandai Namco Entertainment Inc., respectively. Understanding the ONE PIECE: Grand Gourmet developer and publisher credits helps you connect the restaurant sim to its development studio and recognize the company publishing it.

Grand Gourmet puts you aboard Baratie Number Two, where you’ll join the Straw Hat Crew as a new staff member. Its premise centers on building a floating restaurant through cooking, collecting ingredients, and decorating a space that familiar characters will want to visit.

That gives the studio credits a clear context. You’re looking at a single-player management simulation built around the ONE PIECE world, with Kairosoft credited as the developer and Bandai Namco Entertainment credited as the publisher.

Credit	Company	What the credit identifies
Developer	Kairosoft Co., Ltd	The studio developing ONE PIECE: Grand Gourmet
Publisher	Bandai Namco Entertainment Inc.	The company publishing ONE PIECE: Grand Gourmet

Those are the names to remember when comparing this game with other entries in the franchise. A shared series name doesn’t make every ONE PIECE game the work of the same development team.

The distinction also helps when you’re discussing the game with friends. “The Kairosoft-developed ONE PIECE restaurant sim” identifies the project’s studio and genre immediately. “Published by Bandai Namco Entertainment” identifies its publishing credit without confusing that company with the developer.

If you only need the quick answer, those two names settle it. The rest of the credits explain how the game, its licensed characters, and its release platforms fit together.

Understanding the Developer and Publisher Credits

Reading the ONE PIECE: Grand Gourmet developer and publisher credits is straightforward once you separate the two roles. The developer credit identifies the studio behind the game’s development. The publisher credit identifies the company publishing that game.

For Grand Gourmet, Kairosoft occupies the development slot. Bandai Namco Entertainment occupies the publishing slot. Both companies belong in a complete description of who is making and releasing the project, but their credits answer different questions.

If you’re asking, “Who developed this restaurant management game?” the answer is Kairosoft Co., Ltd. If you’re asking, “Who publishes Grand Gourmet?” the answer is Bandai Namco Entertainment Inc.

That distinction matters especially when a recognizable franchise and several platform brands appear together. ONE PIECE identifies the fictional world and characters. Nintendo Switch, Nintendo Switch 2, and Steam identify ways to play. None of those names replaces Kairosoft’s development credit.

Likewise, seeing a game offered through Nintendo’s store doesn’t make Nintendo its developer or publisher. Steam is the PC storefront for this release; Bandai Namco Entertainment remains the credited publisher.

Keep the ONE PIECE: Grand Gourmet developer and publisher names together when writing a wishlist note or sharing the game with someone:

• Developed by Kairosoft Co., Ltd
• Published by Bandai Namco Entertainment Inc.
• A single-player restaurant management simulation set in ONE PIECE

This compact description captures the studio, publisher, format, and setting without turning the credit line into a feature list.

The credits are also useful for keeping expectations grounded. They identify the companies attached to this project. The game’s own announced features explain what you’ll be doing aboard the restaurant. Use both pieces of information when deciding whether its combination of management, cooking, and familiar characters interests you.

How the Studio Credits Differ From ONE PIECE Rights

The ONE PIECE: Grand Gourmet developer and publisher credits sit alongside copyright notices for the franchise. These names describe different relationships to the game, so reading them as one interchangeable list can create confusion.

Grand Gourmet carries a ONE PIECE copyright notice naming Eiichiro Oda, Shueisha, and Toei Animation. It also carries a copyright notice for Bandai Namco Entertainment Inc. Kairosoft’s development credit remains separate from those notices.

Name or group	Where it belongs in the credits	How to read it
Kairosoft Co., Ltd	Game development	The credited developer
Bandai Namco Entertainment Inc.	Publishing and game copyright notice	The credited publisher, also named in the copyright text
Eiichiro Oda / Shueisha / Toei Animation	ONE PIECE copyright notice	Names associated with the franchise rights notice

For players, the practical distinction is simple: a franchise copyright notice answers a different question from a developer credit. It connects the release to ONE PIECE’s rights notices; it doesn’t assign game development to every name it contains.

The same principle applies to platform trademarks. Nintendo, Valve, Apple, and Google appear in connection with their respective systems, storefronts, or trademarks. Their presence in legal text serves a different purpose from the game’s studio credits.

When you describe who made Grand Gourmet, use Kairosoft. When you describe who publishes it, use Bandai Namco Entertainment. When you discuss its setting, characters, and franchise identity, use ONE PIECE.

This keeps the names useful instead of blurring them together. It also makes a difference when searching for the game: the full title plus “Kairosoft” points directly toward its development identity, while the full title plus “Bandai Namco Entertainment” connects it to its publisher.

You don’t need to memorize the entire copyright block to understand the project. Keep the development, publishing, and franchise names in their respective roles.

What Kind of Game Is This Studio Developing?

The ONE PIECE: Grand Gourmet developer and publisher pairing belongs to a restaurant management simulation with a pixel-art presentation. Its announced premise gives the Straw Hat Crew a shared business to build: the second location of the Baratie floating restaurant.

You’ll work with Sanji on dishes, gather ingredients, and seek out additional recipes. Restaurant customization brings another side of the franchise into the project, with decorations inspired by places such as Whole Cake Island and Egghead.

Announced feature	What it brings to the game
Restaurant management	A floating restaurant to develop alongside the Straw Hat Crew
Cooking and recipes	Ingredient selection, dishes made with Sanji, and customizable meal sets
More than 200 customization items	Furniture, building items, and decorations for the restaurant
More than 400 ONE PIECE characters	Characters appearing as staff and customers in pixel-art form

The cooking theme draws directly on ONE PIECE’s food and characters. Announced dishes include Water-Water Meat BBQ and Sea King Penne Gorgonzola, alongside creations inspired by Devil Fruit powers.

Decorating also has a connection to the cast: characters who like your restaurant’s design can become regular customers. Character events and special interactions are part of the announced experience.

These features explain the project more clearly than the franchise name alone. The focus is on serving food, shaping a restaurant, and bringing ONE PIECE personalities into that setting.

For a quick introduction, start with the floating restaurant premise, then look at the cooking and interior customization. Together, they show what Kairosoft’s credited project is built around. The character count adds scale to that concept, while the furniture and decoration selection gives the restaurant its visual variety.

Where to Follow the Game and Choose Your Version

Once you know the ONE PIECE: Grand Gourmet developer and publisher, the next useful step is choosing the platform you intend to play on. The announced platforms include Windows PC through Steam, Nintendo Switch, Nintendo Switch 2, and mobile through the App Store and Google Play.

The release dates differ between Steam and the U.S. Nintendo and Bandai Namco release information.

Platform	Release date	Version detail
Windows PC through Steam	October 22, 2026	Windows version
Nintendo Switch	October 23, 2026	Nintendo Switch version
Nintendo Switch 2	October 23, 2026	Separate Nintendo Switch 2 version
App Store and Google Play	October 23, 2026	Announced mobile platforms

These are calendar dates, so don’t use them as an exact unlock hour when planning your launch session.

For PC, wishlist ONE PIECE: Grand Gourmet on Steam. The Windows release includes single-player play, Steam Achievements, full controller support, and Steam Cloud. Its stated system requirement includes a 64-bit processor and operating system.

For Nintendo players, choose the version that matches your hardware. The Nintendo Switch edition of ONE PIECE: Grand Gourmet and the Nintendo Switch 2 edition are separate products.

The Nintendo Switch 2 edition runs exclusively on Nintendo Switch 2. Save data cannot transfer from the Nintendo Switch version to the Nintendo Switch 2 version, so select your intended edition carefully before purchasing. Avoid buying both versions accidentally.

Both Nintendo editions support TV, tabletop, and handheld modes. American English is among the supported languages, alongside Japanese, French, German, Italian, Korean, Thai, and additional language options.

To explore the project before release, visit the official ONE PIECE: Grand Gourmet website. Its announcement trailer and “A Day in a Rookie Staff Member’s Life” presentation offer an introduction to the restaurant setting and characters.

Use those previews to look at the pixel-art cast, cooking theme, and restaurant interiors. That gives you a concrete picture of this Kairosoft-developed, Bandai Namco Entertainment-published game before you choose your edition.
