Mahjong Soul x Blue Archive Collab Rocketed to #2 on Japan App Store — But OP Couldn't Even Tell Japan Apart from Korea, and Comments Went Full Fact-Check Mode

A single Blue Archive collab character was enough to rocket Mahjong Soul — a relatively niche mahjong gacha — to #2 on Japan's App Store sales chart? That alone is wild. But what's even wilder is that the person who posted this couldn't even figure out which country's chart they were looking at.

It all started when an NGA user shared a screenshot of Mahjong Soul's sales ranking, originally sourced from a Zhihu (Chinese Q&A platform) post. The OP confidently wrote in their thread title: "It's only the Korean chart though" — and the comments section immediately erupted.

User Jason2012514 was the first to call it out: "Korea? Monster Strike? In Korea?" — pointing out that the chart featured Fate/Grand Order and Monster Strike, which are Japan-exclusive titles. Then came the real kicker: the source website game-i.daa.jp is a Japanese-language site, not Korean. The original Zhihu question had incorrectly labeled it as the Korean chart, and nobody bothered to fact-check before running with it.

The OP quickly edited their post and thanked commenters for the correction. But the roasting didn't stop there. A highly-upvoted reply (post #15) dropped a reality check: "Japan's chart doesn't have any WoW-tier dominators — games ranked 50-100 can easily hit #1 just by timing their banners right when bigger games aren't running anything." In other words, climbing the Japanese sales chart is more about timing than raw power.

Post #14, however, pushed back hard against the "Mahjong Soul doesn't deserve it" narrative, dropping three historical screenshots as evidence: the Saki (天才麻将少女) S2 collab in Nov 2022, the Code Geass collab in Apr 2023, and the Fate/kaleid liner Prisma Illya collab in Nov 2023. Each time, Mahjong Soul surged to the top of the charts. Their comment read: "What do you mean 'Mahjong Soul hitting the charts for once?' Has it occurred to you that maybe Mahjong Soul has always had that power?"

The funniest detail came from post #7: "Several of my mahjong squad friends have never touched Blue Archive, but they thought the new collab character was hot enough to whale and pull to pity." They didn't even know what BA was — they just saw a waifu and opened their wallets. Truly, the power of "horny" remains the gacha industry's strongest currency. Post #18 added that this was actually stale news — the banner dropped on the 17th and had already been discussed on the forum before.

Later, someone dug up the actual Korean chart data showing Mahjong Soul at #24 and Fate/Grand Order at #3 in Korea. The real entertainment of this thread wasn't about the sales ranking itself — it was watching the community collectively fact-check a cascading misinformation chain: OP confused Japan with Korea, Zhihu's original question was wrong, and commenters methodically corrected each layer. A textbook case of the internet telephone game gone wrong.
