Professor Layton and the New World of Steam: Release Date, Unlock Times and Platforms

Short answer: Professor Layton and the New World of Steam is out on December 10, 2026 — that’s the date LEVEL-5 gives on its official site. Because that date is Japan time, most of the world actually gets the game on Wednesday, December 9.

Steam: the store page shows December 9, 2026 as the date, but the exact unlock hour is not yet announced.

Nintendo Switch 2 / Switch: Nintendo’s store pages list December 10, 2026. The unlock hour and pre-order details for the eShop are not yet announced.

We’ll update this table as soon as Steam or Nintendo confirm their times.

Which platform should you pick?

All four versions launch on the same day. A few things worth knowing before you buy:

• Switch and Switch 2 are separate versions. The Switch version can’t be upgraded to the Switch 2 version, and the Switch 2 version won’t run on an original Switch. If you play the Switch version on a Switch 2, it runs like the Switch version.
• Mouse support is reported for every version except the original Switch.
• On Steam Deck, the Steam page says touchscreen controls are supported.

Our Switch vs Switch 2 guide covers the differences in more detail.

How we got here

New World of Steam was first revealed for Switch in a Nintendo Direct in February 2023. It was originally aimed at 2025, and on September 25, 2025 LEVEL-5 moved it to 2026. The final December 10 date, along with the PS5 and Steam versions, came out of the September 9, 2026 Nintendo Direct. Digital pre-orders for PS5 and Steam opened on November 12, 2026 (Japan time); see our pre-order guide for the bonus and deadlines.
