What （株）宣伝会議 does

Sendenkaigi Co., Ltd. (株式会社宣伝会議) is a Tokyo-headquartered specialized media and education company in the Japanese marketing and creative communications industry, founded in 1954 with the launch of 月刊『宣伝会議』, Japan's first advertising/marketing specialty magazine. The company operates six integrated business segments: monthly magazine publishing (『宣伝会議』, 『販促会議』, 『ブレーン』, 『広報会議』) plus books and yearbooks; digital media (AdverTimes. advertising-industry news portal and 宣伝会議デジタルマガジン online subscription); education and training (Japan's largest marketing/creative training institution, serving approximately 8,000 companies and 20,000+ individuals annually across all 47 prefectures via online and in-person delivery, including customized corporate programs); events and forums (dozens of annual conferences such as AdverTimes.Days, 宣伝会議サミット, CMO X, SDGs未来会議, ranging from dozens to 10,000+ attendees); awards (宣伝会議賞 with 450,000+ entries over 50+ years since 1962, 販促コンペ, BOVA); and think-tank consulting on organizational talent development, purpose/branding, and social-issue projects for corporations, government agencies, and industry associations.

The business runs primarily on direct enterprise sales via an integrated sales organization, owned-media subscriptions (print and digital recurring), per-participant training fees, ticket and sponsorship revenue from proprietary events, and bespoke consulting engagements. Customers include corporate marketing, PR, and advertising professionals, enterprise teams, government agencies/municipalities, and industry associations. The company has three offices (Tokyo headquarters, Osaka/Kansai branch, Fukuoka/Kyushu branch), is owned by a private equity fund, and operates group subsidiaries including 株式会社マスメディアン (advertising/HR services) and 株式会社KAIGI. Recent strategic activity (2024) includes new product launches in GX/environment business (環境ビジネス), B2B sales strategy (営業戦略会議), AI-themed media (AI会議), and inbound tourism media (インバウンド会議), alongside a corporate repositioning around "Creative Transformation" to mark its 70th anniversary. No proprietary technology platform is disclosed; underlying systems support digital magazine delivery, online training, news publishing, and event ticketing, but the company does not appear to compete on technology infrastructure.
