As of October 8, 2026, no code in the available listings is confirmed working in-game. Roblox Den’s September 21 snapshot listed LEVELUP as active for a 30-minute XP boost, but that is a dated tracker status—not a live test. Other trackers disagree about which codes remain valid. Try the code in the game to confirm whether it still works.
Japanese Supermarket Simulator codes and listed rewards
Japanese Supermarket Simulator is a Roblox konbini-management game where you stock products, set prices, hire staff, and reinvest earnings to expand your store. The following are codes and rewards reported by Roblox Den; its “Check” label means the code was not confirmed as active there.
| Code | Listed reward | Roblox Den status in its September 21, 2026 snapshot |
|---|---|---|
LEVELUP |
30-minute XP boost | Active, according to the tracker; not tested in-game |
HEATWAVE |
2,500 coins | Check; not confirmed active |
MakingMoney |
30-minute double-coin boost | Check; not confirmed active |
WHOOPS |
2,000 coins | Check; not confirmed active |
Treat |
Two candy bars | Check; not confirmed active |
Code spelling and capitalization are shown as listed. The status and rewards come from Roblox Den’s code page; they do not establish that a code will redeem today.
Why code lists disagree
Trackers report conflicting statuses, so a page’s advertised count of active codes is not proof that every entry works. Game.Guide’s page claims 25 active codes, yet its October 7 history marks HEATWAVE, GAMEON, MakingMoney, THANKSSUSANNANDACID, and WHOOPS as expired. Roburo’s Japanese-language list, based on a September 5 check, includes HEATWAVE among five active codes and 21 expired ones. These snapshots do not agree, and none substitutes for checking a code in the game.

Accordingly, LEVELUP is best described as listed active by Roblox Den on September 21, 2026, not verified working as of October 8. The other entries in the table are worth testing, but their “Check” status is not confirmation that they remain valid.

Where to look for future codes
The official Roblox experience listing encourages players to follow the game and enable notifications for updates. It does not promise that every promo code will be announced there, so treat notifications as one way to hear about game updates, not a complete code feed.
