Yukiko S.

Japan Game Market Consultant | Steam Launch, PR & Viral Campaigns

I help overseas game studios launch and win in Japan. With 18+ years inside Japan's game and entertainment industry (ex-gumi, ex-COLOPL), I've led end-to-end brand and marketing strategy across 50+ titles -- spanning mass media, digital ads, SNS, PR, and events as an integrated marketing producer for companies ranging from major Japanese publishers to indie studios. 【WHAT I BRING】 - Viral campaign design: my personality-quiz campaigns have reached 3,000,000+ cumulative participants; my own diagnostic platform, Seikaku Navi, has grown to 1.2M+ users with 97,000+ proprietary psychology data points - Developer's-eye view: I'm currently marketing my own Steam title, Bungo Catharsis, handling everything from the store page to a companion viral quiz driving wishlist conversion - Recent industry work: Marketing lead for "Heavenly Guitars" (Sonet Game Studios, Sony Group), covering global ad strategy, SNS, music-rights negotiation, anime IP collaborations, and international PR - Technical range: in 2023 I built a WebGL live game supporting 16 simultaneous players 【HOW I CAN HELP YOUR JAPAN LAUNCH】 - Steam store-page audits (copy, pricing, tags, screenshots) from the Japan storefront - Japan media & streamer/VTuber outreach strategy - Japanese SNS (X/Twitter) launch playbooks - Viral personality-quiz content built around your game's cast - Full Japan launch campaigns, from press kit to community building 【HOW I WORK】 I'm Tokyo-based and work async, in writing -- clear briefs, documented deliverables, fast turnaround across time zones. Your overnight is my workday. Send me your Steam link or project brief, and let's make Japan your best-performing region.
