This Week's Theme
Event-driven revenue concentration
Japan's mobile game revenue spiked 100.6% in 7 days, driven by a handful of high-volatility titles—Azur Lane, Gakuen iDOLM@STER, and Arknights: Endfield each saw double-digit rank recoveries.

Without that Crisis Contract update, Endfield's 69-rank climb collapses.

This Week's Standout Titles
Azur Lane rose 16 positions (#75→#59) on June 27, fueled by the 'Phantom Cavalcade' limited event, a Bellasara Akihabara gacha revival, and new character Kurea's pick-up gacha starting June 22.
Gakuen iDOLM@STER dropped from #19 to #79 between June 21–26, then rebounded to #20 on June 27—likely a new gacha launch or weekend campaign, not organic retention.
변신 키우기 × 블레이드 키우기 collab event 'Beyond the Sandstorm' grants pick-up hero tickets and premium materials just for logging in, driving engagement during the 1.5 version update.
Data Movement Analysis
RO仙境傳説：世界之旅 climbed 10 positions (#26→#16) in one day after opening server '伊米爾之心' on June 26 and launching event '鮫人幻歌·碧瀾覆海' on June 24.
Arknights: Endfield rose 69 positions (#92→#23) over 6 days, correlating with the 'Crisis Contract Reburn Trial Operation' update on June 26 and a pre-registration lottery event.
GIRLS' FRONTLINE 2: EXILIUM's 1.5 anniversary update on June 25 added limited event '거울 고치와 죄수 나비' and new elite doll '바스티', plus a cumulative attendance event '휘황찬란한 연회'.
Japan's +100.6% revenue surge is concentrated in a few high-volatility titles—a classic event-driven spike, not broad market health.
Korea's strategy genre dominates at 35% of revenue, with a moderate +18.1% weekly uptick—steady, not flashy.
What to Watch Next Week
마비노기 모바일 held #1 in KR iOS this week; watch if its dominance persists post-event, or if new releases chip away at its lead.
오딘: 발할라 라이징 also topped KR iOS; next week's performance will test whether its momentum is event-driven or sustainable.
神魔之塔 ranked #1 in TW iOS; keep an eye on whether upcoming collabs or updates can maintain its position against rising competitors.
ブルーアーカイブ at #3 in JP iOS; its next event or gacha cycle could push it higher, but recent volatility suggests caution.
Honkai: Star Rail at #4 in JP iOS; a new character banner or patch could trigger a rank surge, but sustained growth depends on content cadence.
Editor's Note
Next week, monitor if Japan's 100.6% revenue spike holds or reverts—event-driven surges often fade within 7–14 days. Korea's strategy genre stability is a safer bet.
