ONE PIECE: Grand Gourmet is scheduled for October 23, 2026 on Nintendo Switch, Nintendo Switch 2, PC through Steam, iOS, and Android. The console editions have published download estimates and play-mode details; official PC minimum specifications and mobile device requirements have not yet been published. That means you can confirm whether your Switch is supported, but you should not rely on an assumed CPU, graphics card, operating-system version, or phone model for the Steam and mobile releases.
This guide separates confirmed requirements from information still pending, explains the difference between the Switch and Switch 2 editions, and gives a practical pre-release checklist. Details below reflect official pages available through October 13, 2026, before the announced launch date, so storefront specifications may change.

Confirmed platforms and requirements at a glance
Bandai Namco describes ONE PIECE: Grand Gourmet as a single-player management simulation developed by Kairosoft. The publisher’s announcement lists five platform families: Nintendo Switch, Nintendo Switch 2, PC via Steam, iOS, and Android. The release date announced for all listed versions is October 23, 2026.
| Platform | What is officially confirmed | What is not yet published |
|---|---|---|
| Nintendo Switch | Digital listing; estimated download of 344 MB; TV, tabletop and handheld modes; touch-screen support; one player. | Switch Lite experience caveats and any accessories needed for a particular setup. Nintendo does not identify those accessories on the listing. |
| Nintendo Switch 2 | Separate Switch 2 edition; estimated download of 291 MB; TV, tabletop and handheld modes; touch-screen support; one player. | Whether saves transfer between editions or whether an upgrade path exists. |
| PC (Steam) | PC release through Steam announced by the publisher. | Minimum and recommended CPU, RAM, GPU, operating-system version and storage requirements. |
| iOS | App Store release announced. | Minimum iOS version, supported iPhone and iPad models, storage and regional availability. |
| Android | Google Play release announced. | Minimum Android version, supported device list, processor/GPU requirements, storage and regional availability. |
The absence of a specification is itself important: the official pages reviewed do not establish a PC or mobile configuration. Do not infer requirements from the game’s pixel-art presentation or from another Kairosoft title.

Release date, editions and where the listings come from
Announcement and timing
Bandai Namco announced the October 23, 2026 launch in its June 9, 2026 news post: ONE PIECE: Grand Gourmet serves culinary adventure on 23 October 2026. The publisher’s main game page, ONE PIECE: Grand Gourmet, identifies Steam, the App Store and Google Play in addition to the two Nintendo systems.
Because October 23 has not arrived as of the latest official information covered here, treat every requirement as pre-release information. A store page can update its size, compatibility note or regional availability without changing the announced title or date.
Digital and physical editions
The US Nintendo pages describe digital Switch editions. Bandai Namco Europe’s English page presents a Standard Edition with physical and digital choices, but that page does not prove that a physical cartridge is stocked by a particular retailer or sold in every country. If you are buying a physical copy, confirm the edition, region, stock and retailer listing rather than assuming worldwide availability.
Nintendo Switch system requirements
Hardware and storage
The Nintendo Switch listing gives an estimated download size of 344 MB. This is a storefront estimate, not a measured post-install footprint; an update or regional package can change the amount of free space needed. Leave more free storage than the estimate so the console can download and install updates without first deleting another game.
Rank #2
- 5-in-1 USB-C Hub: Experience comprehensive connectivity featuring a Power Delivery input, two USB-A 2.0 ports, a USB-A 3.0 port, and an HDMI port. (Note: The USB-C power delivery input port is only for connecting an external wall charger to power your laptop and cannot power peripheral devices.)

Modes, players and controls
Nintendo lists TV, tabletop and handheld play modes, one-player support and a touch-screen feature for the Switch edition. Those entries describe the software’s supported configurations, not a promise that every menu is exclusively touch-controlled. In TV mode, use the normal Switch controllers; in handheld mode, the built-in display provides touch input where the game supports it.
Switch Lite qualification
Nintendo’s listing warns: “Software compatibility and play experience may differ on Nintendo Switch Lite. Additional accessories may be required(sold separately). See support for details.” The page does not name the accessories. A Switch Lite owner should therefore verify the current support information before purchase, especially if a feature or control method appears to require detachable controllers, a stand or another peripheral.
Nintendo Switch 2: edition and compatibility explained
The separate Switch 2 listing
Nintendo lists a distinct Switch 2 edition with an estimated download size of 291 MB. It supports TV, tabletop and handheld modes, touch-screen input and one player, just like the Switch listing. The 291 MB figure is an estimate for that listing and should not be treated as the final installed size.
Recommended Free Tools
What “supported” means for the original Switch edition
The original Switch product page also carries Nintendo’s compatibility statement: “Supported – Game behavior is consistent with Nintendo Switch.” This means Nintendo reports that the Switch edition behaves consistently when played on Switch 2. It does not automatically mean the two editions are interchangeable.
Rank #3

Do not assume an upgrade or save transfer
The official listings reviewed do not state that a Switch purchase upgrades to the Switch 2 edition, nor do they confirm save-data migration between editions. Check the wording on the store page for the exact version you intend to buy and wait for an explicit Nintendo or publisher statement before planning a transfer.
PC (Steam) requirements: what is known and unknown
PC availability through Steam is confirmed by Bandai Namco, but no official minimum or recommended specifications were present in the pages reviewed. There is currently no authoritative number for:
- Windows or other operating-system versions;
- processor model or instruction-set requirement;
- system memory (RAM);
- graphics processor, video memory or graphics API;
- free disk space; or
- screen resolution, controller or input requirements.
Do not convert the 291 MB or 344 MB Nintendo estimates into a PC storage requirement. Console packages, compression and patching can differ by platform. Likewise, pixel-art graphics do not establish that an older laptop will run the game; the game’s framework, operating-system support and emulator layers can affect performance independently of visual complexity.

- Open the official Steam store page when it is published and read the developer’s minimum and recommended sections, including the operating system and storage line.
- Compare those entries with your computer’s CPU, RAM, GPU and available disk space. Use the model names shown in your system information rather than judging by a computer’s age or brand.
- Check whether the page labels cloud saves, controller support, family sharing or other Steam features that matter to your setup; those are separate from minimum hardware requirements.
- Recheck the listing after launch, because a day-one patch can alter storage needs or supported operating systems.
iOS and Android support
What the publisher has announced
Bandai Namco identifies both the App Store and Google Play as release channels. That confirms intended iOS and Android distribution, but it does not identify a universal phone or tablet specification.
Rank #4

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
Requirements still pending
The official material reviewed does not state a minimum iOS version, Android version, supported chipset, RAM requirement, GPU, download size, installed size or compatible device list. It also does not establish that the game will launch in every country at the same time. App Store and Google Play pages normally show the applicable operating-system version, device compatibility and regional availability once a listing is live; use those entries for your specific account region.
Practical mobile preparation
- Use the store listing tied to your own Apple ID or Google account, since compatibility can differ by region and device model.
- Check both the required operating-system version and the device’s free storage; a download figure alone does not account for unpacking or updates.
- Install system updates before launch if your device is eligible, then confirm that the game appears as compatible rather than relying on a similar phone’s result.
- If the listing is unavailable in your country, do not assume that sideloading or changing regions is supported; wait for an official regional release notice.
Storage planning and download-size caveats
Only Nintendo has published numerical download estimates so far: 344 MB for the Switch listing and 291 MB for the Switch 2 listing. They are not a cross-platform comparison and are not guarantees of the final occupied space. Consoles may reserve temporary installation space, and later patches can increase the total.
| Store listing | Estimated download | How to interpret it |
|---|---|---|
| Nintendo Switch | 344 MB | Estimate shown by Nintendo for the Switch edition; final installed size and updates may differ. |
| Nintendo Switch 2 | 291 MB | Estimate shown by Nintendo for the separate Switch 2 edition; it is not an upgrade-size promise for the Switch version. |
| Steam, iOS and Android | Not stated in the official pages reviewed | Wait for the platform’s own listing instead of extrapolating from a console figure. |
Before downloading either console edition, open the product page on the console and check the current size and available storage. If space is tight, archive another title rather than deleting its save data; the Nintendo system’s archive function is separate from deleting software, but the exact menu wording can vary by system software version.

Languages and single-player scope
The US Nintendo listings identify these languages: Japanese, French, German, Italian, Spanish, Korean, Simplified Chinese, Latin American Spanish, Brazilian Portuguese, Traditional Chinese, American English and Thai. Language availability can be tied to the software region or system settings, so check the listing for your account region if a particular language is essential.

The game is listed for one player. Bandai Namco describes the core loop as working with the Straw Hat crew to operate Baratie Number Two, gather ingredients, create dishes and decorate the restaurant. The publisher says the game includes more than 400 ONE PIECE characters and more than 200 furniture, building and decorative items. Those are publisher-described content counts, not independently measured totals, and they do not change the platform requirements.
Which version should you choose?
Choose Nintendo Switch when
- You already own a Switch and want the published TV, tabletop and handheld modes.
- A 344 MB estimated download fits your available storage.
- You are comfortable checking the Switch Lite caveat if you use that model.
Choose Nintendo Switch 2 when
- You want the separately listed Switch 2 edition and its 291 MB estimate.
- You prefer to buy specifically for Switch 2 rather than rely on backward compatibility.
- You have confirmed the edition and any save-data expectations on the current store page.
Choose PC or mobile when
- You prefer Steam, iOS or Android and can wait for the platform listing to publish its technical requirements.
- You are willing to verify your own operating system, device model and free storage at launch.
There is no evidence in the published material that one platform has extra gameplay content, cross-save support or a performance advantage. Make the decision on confirmed availability, controls, storage and your existing hardware rather than on unannounced features.
Pre-release checklist
- Confirm the date and platform on the current store page; the announced date is October 23, 2026.
- Identify the exact edition: Switch, Switch 2, Steam, iOS or Android.
- For Nintendo, compare the listing’s current download estimate with free storage and note the one-player, touch-screen and play-mode entries.
- If using Switch Lite, read Nintendo’s compatibility warning and check whether your chosen control setup needs an accessory.
- For PC, do not buy or install until Steam publishes CPU, RAM, GPU, operating-system and storage information.
- For mobile, use the App Store or Google Play compatibility result for your own account and device, including the required OS version.
- After release, check for updates and revised requirements before troubleshooting a launch or performance problem.
The authoritative pages to monitor are Nintendo’s Switch listing, Nintendo’s Switch 2 listing, and Bandai Namco’s official game page. They are the appropriate places to verify changes made between the pre-release announcement and launch.
