How to redeem codes
Step 1: Open Roblox and start the Kaizen experience from its game page.
Step 2: Once you load into the game, look at the top-left of the screen and click the gear or settings icon.
Step 3: In the settings menu, scroll down until you see the code input field, usually labeled with “type code here” or similar.
Step 4: Copy a working code from the list, paste it into the field exactly as shown, and confirm using the verify or red check mark button.
Step 5: If the code is valid and active, your clan spins, Yen, or boosts are added to your account immediately.

Why codes might not work
- The code has expired and the developers have disabled its rewards.
- There is a typo, missing character, or extra space; Kaizen codes are case-sensitive and must match exactly.
- The code was already redeemed on your Roblox account; most codes can only be used once per account.
- The Kaizen server or your client is out of date; rejoin the experience or restart Roblox and try again.
Where to find more codes
New Kaizen codes are shared through the official Kaizen Discord server at discord.com/invite/kzn and the Lajebo Games JJK Roblox group at roblox.com/communities/34378400. These channels post codes when updates, milestones, or events go live.

Kaizen codes are free, time-limited bonuses that must be entered exactly as written, so copy and paste them when possible, use them quickly before they expire, and avoid any third-party “code generator” sites or tools that ask for your Roblox login or personal information.
