You designed a good reward event. The payout is fair, the task difficulty matches your early-game pacing, the targeting is right.
It still doesn't arrive the same way for everyone.
82.2% of Japanese reward users run two or more services at the same time, and 64.1% do it every single day (Source: GMO Media_2026-06_Poi-katsu Survey). The moment your offer appears on screen, it isn't evaluated on its own. It sits next to someone else's offer, in front of someone who has done this hundreds of times, and gets judged in seconds.
That number is usually read as good news: rewards work in Japan. They do. But it's only half of what the number says. The other half is that this audience isn't new to the format — it's experienced. And experienced audiences compare.
Exposure Is Not Uniform
The same campaign does not land the same way across different media. In Japan, that gap is unusually wide.
More than half of Japanese players — 52% — focus on one to three core titles, while players in the US and UK rotate across four or more games weekly (Source: eMarketer_2025_East-West Dividet). Discovery works differently too: 53% of Japanese gamers rely on app store exploration, while 77% of US gamers discover games through social platforms.
Getting into a narrow consideration set is a different problem than buying a slot in a wide rotation. And the entry cost is already higher here — Japan is the hardest market in APAC to convert an impression into an install, roughly three times harder than Korea or Australia and four times harder than the US or UK (Source: adjoe_2025_Advertising Mobile Games Across APAC5).
More impressions don't solve a consideration-set problem. Where you appear does.
The Conditions Decide, Not the Campaign
Running a reward campaign isn't the decision. The conditions you attach to it are.
Every reward tier a user has to clear reduces the number who reach the next one. That isn't a design failure — it's the design working. Set the bar high and fewer users clear it. Set it low and you attract users you weren't aiming for.
What's easy to miss is that this trade-off behaves differently on every partner you run with. In our own campaigns, step-level completion rates diverge noticeably depending on a partner's core audience — whether it skews female or male, and whether that audience is game-native or came in through non-gaming reward activity. The same task, the same reward, the same completion window will produce different drop-off curves across two media partners on the same day.
Applying one fixed condition set across every partner guarantees it's mistuned somewhere. The condition set has to be read against who is actually on the other side of it.
What Actually Makes Someone Finish
Reward size alone doesn't determine completion. And what motivates completion isn't the same everywhere.
60% of Western players cite login rewards as a key reason to keep playing, while players in Japan and Korea favor stories, events, and exclusives instead (Source: eMarketer_2025_East-West Divide). In Japan specifically, 47% point to limited-time events and exclusive content (Source: Mistplay_2025-11_Mobile Gaming Across Markets). A reward structure that converts in one market doesn't automatically motivate in another.
Progression matters here too. 91.2% of Japanese respondents said that accumulating points increases how often they use a service (Source: GMO Media_2026-06_Poi-katsu Survey). A design that maintains the sense of moving forward fits this market better than one built around a single large payout at the end.

Designing a good reward event and making sure it arrives under good conditions are two different jobs.
In Japan, the second one comes down to three things: which media you appear on, what conditions you attach, and what actually makes someone finish.
None of them is solved by buying more impressions.
