In our August 2026 mobile game ranking analysis for Japan and Korea , Whiteout Survival stood out as one of the strongest titles in both markets.
But why has the same game been able to perform so well in two markets with different user preferences and cultural backgrounds?
Looking at the Whiteout Survival UA strategy in Japan and Korea, we found some interesting differences in both user acquisition structure and ad creatives.
In this article, we look at the differences in UA (user acquisition) creatives between Japan and Korea, based on market data from Apptica and video ads available in the Meta Ad Library.

Data Tells Us About Platform Differences in JP & KR
Apptica data shows clear differences in download and revenue structure by platform in Japan and Korea.
Japan
Monthly revenue ranges from approximately $13 million to $22 million, showing the large scale of the Japanese market.
One particularly noticeable point is the high share of organic downloads on iOS, which consistently remains in the 80% to 90% range.
Korea
Monthly revenue is approximately $2 million to $3.8 million.
Looking at the platform breakdown, Android (AOS) has a very high organic download share of around 80% to 90%, making it a key user acquisition base in Korea, much like iOS is in Japan.
These figures are Apptica estimates, so they are not enough to determine the actual media budget allocation.
Still, the data suggests that even for the same game, the user acquisition structure differs by market and OS.
Because both markets show a high share of organic downloads, it is also possible that awareness generated through paid advertising contributes to organic traffic, such as users later searching for the game in the app stores.
How Do the Ad Creatives Differ?
Japan
The Meta creatives used in Japan show a wide range of approaches.
1.A wide variety of formats:
There are many live-action creative styles, including interview-style videos, couple- or drama-based ads, comedian-led content, and Q&A-style formats.
2.Strong hooks in the first few seconds:
Drama-style and interview-style videos often use the opening few seconds to quickly catch the viewer’s attention. We also found examples where only the opening scene was changed while the rest of the creative remained similar, suggesting ongoing testing of different hooks.
3.Fast response to seasonal events and trends:
Some creatives also reflect seasonal events and current trends, such as actors wearing soccer jerseys during the World Cup period.
In Japan, Whiteout Survival appears to prepare many different creative patterns and rotate them in relatively short cycles of around one week.
From what we observed, this fast testing cycle may be one of the factors supporting strong install performance.
Korea
In Korea, the Meta creatives show a different approach.
1.Gameplay-focused creatives:
Among ads launched since June 2026, many do not feature people at all. Instead, they focus mainly on gameplay footage, sometimes combined with voice-over narration or meme-style editing.
2.A shift away from live action:
In March and April 2026, Whiteout Survival also ran live-action creatives using drama-style scenes and cosplay. More recently, however, the creative mix appears to have shifted toward gameplay-focused videos.
There are several possible ways to interpret this.
One possibility is that the Korean market does not yet have the same level of UGC production and testing structure as Japan.
Another is that the shift may be based on performance data showing that Korean users respond better—or generate higher LTV—when they see actual gameplay or meme-style content rather than live-action drama.
Localization Behind a Global Hit
The biggest takeaway from the Whiteout Survival case is that even a major global title does not simply reuse the same creatives across markets. Instead, it appears to localize its UA strategy for each market.
Looking at older ads also shows that these creative approaches change over time, sometimes within just a few months.
The key may be to adapt the creative strategy to each market’s culture, user response, and production environment—whether that means changing the video format, testing different hooks, or reflecting seasonal events.
That kind of market-specific creative localization may be one of the reasons why Whiteout Survival continues to rank highly across multiple markets at the same time.
