If you’ve recently dusted off your 3DS or picked up the remaster on Nintendo Switch, you’ve probably realized that yo kai watch 1 qr codes are basically the lifeblood of the early game. Honestly, trying to fill out your Medallium without them is just making life harder for yourself. You're out here hunting for a rare S-Rank like Cruncha or Shadow Venoct, and the RNG gods are just giving you a pile of ramen or a rusted nail.
It’s frustrating.
But here is the thing: most of the "guides" you find online are either broken links from 2015 or total chaos. I've spent way too much time staring at blurry JPEG squares to see what actually works. The system is actually pretty simple once you get past the region-locking headache, which—spoiler alert—is the main reason your codes aren't working.
Where do you even scan these things?
You can't just open a menu and start scanning. The game makes you earn it, but only slightly.
First, you have to play through the story until you reach Chapter 2. Once you're there, head over to Uptown Springdale. Look for a building called Piggleston Bank. It's the one that looks like, well, a bank. Walk inside and talk to the lady at Counter 1.
She’s the gatekeeper. She’ll open up the 3DS camera for you.
On the Nintendo Switch version, things are a bit different. Since the Switch doesn't have a camera for QR codes, the "scanning" process was replaced with local physical medal communication or specific passwords in the Japanese release. However, for most of us playing the classic 3DS version, that camera at Piggleston Bank is the only way to turn physical plastic medals (or digital pictures of them) into in-game loot.
The Region Lock Trap
This is the biggest mistake I see people make. Yo Kai Watch 1 QR codes are region-locked. If you have a North American copy of the game, you must scan North American (Hasbro) QR codes. If you try to scan a Japanese (Bandai) code from a cool medal you found on eBay, the game will just stare at you blankly. It won't work. The same goes for European copies; they need their specific PAL-region codes.
If you’re wondering why that "infinite coin" list you found on a random forum isn't doing anything, check the region. Most "master lists" on Reddit or GameFAQs will specify if they are US or JP.
What do you actually get from scanning?
Basically, you’re looking for Crank-a-kai Coins.
The Crank-a-kai is that giant gashapon machine under the Sacred Tree at Mt. Wildwood. Normally, you only get a few tries a day, and finding coins in the wild is a slow grind. Scanning codes bypasses the grind.
When you scan a medal's QR code, you usually get a colored coin that corresponds to that Yo-kai's tribe.
- Red Coins: Brave Tribe (Think Jibanyan or Siro).
- Yellow Coins: Mysterious Tribe (Frostail is the big prize here).
- Orange Coins: Tough Tribe (Looking for Goldenyan? Use these).
- Pink Coins: Charming Tribe (Damona is the S-rank goal).
- Green Coins: Heartful Tribe (Auntie Heart is an incredible healer).
- Blue Coins: Shady Tribe (Count Cavity lives here).
- Purple Coins: Eerie Tribe (Eterna is a beast).
- Light Blue Coins: Slippery Tribe (Shadow Venoct—arguably the best Yo-kai in the game).
There are also Five-Star Coins and Special Coins. These are the holy grail. They have a significantly higher chance of dropping an S-Rank Yo-kai instead of just a "Large Exporb" or some "Black Tuna."
The Jewelnyans: The real reason to scan
If you want the shiny, gem-encrusted versions of Jibanyan—like Sapphinyan, Emenyan, or Rubinyan—you need specific QR codes.
Scanning these doesn't just give you a coin; it gives you a Special Item. For example, scanning the Sapphinyan medal gives you the "Sapphire Bell." Once you have that bell in your inventory, Sapphinyan will actually appear in the game (usually at the Seaside Park in Breezy Hills) for you to battle and befriend.
Without those codes, those cats are essentially locked away.
Why some codes "fail" even if they are correct
Ever had the game tell you a code has "already been used"?
That’s because every single physical medal produced has a unique ID. However, the game only tracks if that specific ID has been used on your save file.
Back in the day, collectors would post photos of their medals online. If 500 people scanned the same photo, it worked for all 500 of them—as long as they hadn't scanned that exact medal image before.
But here’s the kicker: if you find a "QR Code Generator" or a sheet of 100 codes, and you’ve already scanned a Jibanyan medal from a different source, the game might recognize them as the same "type." It’s a bit of a gamble, but generally, the more unique images you find, the more coins you get.
Actionable Tips for 2026
Since the physical medals are now "vintage" (which makes me feel old), you aren't going to find them at Target anymore. Here is how you actually handle this today:
- Use the Fan Archives: Sites like Yo-kai Watch World or specific archived Reddit threads (search for "Yo-kai Watch 1 QR Code Mega Thread") have high-quality, scannable images.
- Brightness Matters: If you’re scanning off a phone screen, turn your brightness all the way up. The 3DS camera is, frankly, terrible. It needs all the light it can get to recognize the patterns.
- The "Crank-a-kai" Reset: In the original game, the results of your coins are predetermined when you start your save file. You can't just save, use a coin, and reset if you don't like what you got. You’ll get the same thing every time. The only way to "change" your luck is to use a different color coin.
- Don't ignore Passwords: While we're talking about QR codes, don't forget the post office. The lady at the Post Office in Uptown Springdale takes text passwords (like "W3LCOM3") which give Five-Star coins. It’s a great supplement to your QR scanning spree.
If you’re stuck on a specific boss or just want a team that isn't just a bunch of Rank-E cats, spend twenty minutes scanning a coin list. It's the closest thing the game has to a legal "cheat mode," and honestly, it makes the experience way more fun. Just remember: check your region, go to the bank, and keep your phone screen bright.
