Yo-Kai Watch uses QR codes to unlock special coins that summon rare Yo-kai not available through normal gameplay. The most searched codes are for 5 star coins, which give the best odds of summoning powerful Yo-kai at the Crank-a-kai machine, and light blue coins, which unlock specific Yo-kai tied to that coin type. Knowing where to find working codes and how to scan them correctly saves a lot of time.
Here is how the QR code system works across Yo-Kai Watch 1, 2, and Blasters, which coin types you can get, and where to find codes that still work today.
How QR Codes Work in Yo-Kai Watch
Yo-Kai Watch on the Nintendo 3DS has a dedicated QR code scanner built into the Yo-kai Watch menu. Each QR code encodes a specific coin type or Yo-kai item. Scanning the code adds the coin to your Crank-a-kai inventory, and you then use the coin at the Crank-a-kai machine to attempt to summon the associated Yo-kai.
Unlike Monster Hunter Stories, where codes validate against an external server, Yo-Kai Watch QR codes contain the coin data directly in the pattern. This means they do not expire because of server changes. A valid code works as long as you have not reached the maximum number of times that particular code can be scanned.
Most Yo-Kai Watch QR codes have a scan limit of three to five times per game save. Once you hit that limit on a specific code, scanning it again produces no result. This is why players often need multiple different codes of the same coin type rather than scanning one code many times.
How to Scan QR Codes in Yo-Kai Watch
- Open Yo-Kai Watch on the Nintendo 3DS
- Press the Y button on the main map screen to open the Yo-kai Watch menu
- Select the QR Scanner option from the menu wheel
- The 3DS camera activates
- Hold the camera steady and point it at the QR code image on your phone screen or printed page
- The game confirms the scan and adds the coin or item to your inventory
- Go to the Crank-a-kai machine and use the coin to attempt to summon the Yo-kai
The QR scanner in Yo-Kai Watch reads the code directly without any internet connection. You can scan codes entirely offline, which is one advantage over games with server-side validation.
Yo-Kai Watch QR Codes for 5 Star Coins
Five star coins are the most sought-after coin type because they give the highest probability of summoning rare and powerful Yo-kai from the Crank-a-kai. Several legitimate sources distribute working 5 star coin QR codes:
- r/yokaiwatch on Reddit: The community subreddit maintains pinned threads and wikis with 5 star coin QR codes. Posts include scan confirmation dates and notes on which codes have hit their scan limit for many players
- GameFAQs Yo-Kai Watch boards: The most comprehensive documented lists of QR codes for both Yo-Kai Watch 1 and 2, with player notes on current working status
- YouTube: Many Yo-Kai Watch YouTube channels have dedicated QR code videos with codes displayed on screen that you can scan directly from the video
- Official Level-5 and Nintendo promotions: Some 5 star coin codes were distributed through official Nintendo Zone locations and Level-5 events during the game’s launch period in the West between 2015 and 2016
When trying codes from online lists, check for recent comments confirming the code still works. Five star coin codes that appeared in official Nintendo promotions tend to have higher scan limits or unlimited scans compared to codes from unofficial sources.
Yo-Kai Watch Light Blue Coin QR Codes
Light blue coins, also called ice blue or sky blue coins depending on the source, unlock a specific set of Yo-kai in the Crank-a-kai. With 5,400 monthly searches for this specific coin type, it is clearly something many players want but find difficult to obtain through normal gameplay.
Light blue coin QR codes work the same way as 5 star coin codes in terms of scanning mechanics. The difference is the Yo-kai pool the coin draws from. Light blue coins summon Yo-kai from the cold or ice affinity group, which includes several rare and powerful options not easily obtained otherwise.
The community lists for light blue coin codes are smaller than 5 star coin lists because fewer official codes were distributed for this specific coin type. Check the GameFAQs boards and the Yo-Kai Watch subreddit for the most up-to-date lists with working status confirmation.
Yo-Kai Watch 2 QR Codes
Yo-Kai Watch 2 uses the same QR scanning mechanic as the original game. The coin types available include regular coins, rare coins, special coins, Cheerful coins, and 5 star coins. The Crank-a-kai in Yo-Kai Watch 2 has a different Yo-kai pool than the original game, so codes from Yo-Kai Watch 1 produce different results when scanned in Yo-Kai Watch 2.
Glitzy coins are a Yo-Kai Watch 2 specific coin type that players frequently search for. Glitzy coins summon rare Yo-kai exclusive to that title. QR codes for glitzy coins were distributed through official Nintendo promotions and appear in community lists maintained by the GameFAQs boards.
The scan limit system in Yo-Kai Watch 2 works the same as in the original. Three to five scans per code per save file is typical. Building a collection of different codes for the same coin type gives you more scans overall.
Yo-Kai Watch Blasters QR Codes
Yo-Kai Watch Blasters, released as Yo-Kai Watch Blasters: Red Cat Corps and White Dog Squad in the West, uses QR codes for the same coin system. The game has its own Crank-a-kai with a Yo-kai pool specific to Blasters. QR codes distributed for the base Yo-Kai Watch games do not work in Blasters, and Blasters-specific codes produce different results.
Five star coin codes for Blasters were distributed through official Nintendo events and some third-party promotion partners during the game’s launch window. The community maintains separate lists for Blasters codes from the lists used for Yo-Kai Watch 1 and 2.
Why Some Yo-Kai Watch QR Codes Stop Working
Unlike server-validated games, Yo-Kai Watch QR codes stop working at the game level rather than the server level. Each code has a built-in scan limit encoded into it. Once you reach that limit on your save file, the game refuses further scans of that code.
This means a code that worked perfectly for one player may show no result for you even though nothing about the code itself has changed. You have simply reached its limit on your specific save. The solution is to find additional different codes of the same coin type rather than trying to re-scan the same code.
A second reason codes stop working is save file specificity. QR codes in Yo-Kai Watch track redemptions by save file. If you start a new game, previously maxed-out codes become available again on the new save.
Frequently Asked Questions
How do I scan QR codes in Yo-Kai Watch
Press Y on the main map screen to open the Yo-kai Watch menu, then select the QR Scanner. The 3DS camera activates and you hold it up to the QR code image. No internet connection is needed. The game reads the code locally and adds the coin or item to your inventory immediately.
Where can I find Yo-Kai Watch 5 star coin QR codes
The r/yokaiwatch subreddit, GameFAQs Yo-Kai Watch boards, and YouTube channels dedicated to the game are the most reliable sources. Look for posts with recent confirmation that specific codes still have scans available. Official Nintendo promotional codes tend to have higher or unlimited scan limits compared to community-generated codes.
What are light blue coin QR codes in Yo-Kai Watch
Light blue coins are a specific coin type that summons Yo-kai from the cold or ice affinity group at the Crank-a-kai machine. QR codes for this coin type were distributed through official promotions and appear in community code lists on Reddit and GameFAQs, though the available list is smaller than for 5 star coins.
Do Yo-Kai Watch QR codes expire
Yo-Kai Watch QR codes do not expire because of server changes. They have a per-save-file scan limit built into the code itself. Once you reach that limit on your current save, the code produces no result. Starting a new save file resets all scan limits. Codes from the original game can also be scanned in Yo-Kai Watch 2 for potentially different Yo-kai.
Can I use Yo-Kai Watch 1 codes in Yo-Kai Watch 2
Yes, but the results differ. The Crank-a-kai in Yo-Kai Watch 2 has a different Yo-kai pool than the original game. A 5 star coin scanned in Yo-Kai Watch 2 draws from the Yo-Kai Watch 2 pool rather than the original game’s pool. The coin type functions the same way but summons different Yo-kai.
Why is my Yo-Kai Watch QR code not working
The most common reason is that you have reached the scan limit for that specific code on your save file. Find additional different codes of the same coin type and try those. If you have not scanned that code before and it still fails, the image quality may be too low for the 3DS camera to read. Try a higher resolution version of the code or reduce ambient glare on the screen displaying it.
Build Your Coin Collection One Code at a Time
Yo-Kai Watch QR codes are one of the few gaming QR systems where the codes genuinely work offline and do not depend on any external server. The scan limit per save file is the main constraint, which is why building a list of multiple different codes for your target coin type is more useful than searching for one perfect code.
For creating standard QR codes for any purpose outside of game systems, the QR code generator handles any URL, contact, or text code with full design options. And for a broader look at how QR codes store and encode data, the how QR codes work guide explains the mechanics clearly.
