What New Stream does

New Stream (株式会社ニューストリーム) is a Japan-based digital strategy consulting firm founded in 2000 by Representative Director Shiiba Hiroshi, operating as a group company of WOW WORLD GROUP and headquartered in Minato, Tokyo. The firm organizes its work around two pillars: Marketing Support (email marketing under the Email Factory brand, SNS marketing via SNS lab works, website construction and operation via Web Strategy Port, customer engagement surveys via Engagement Scope for Customer, and purchase-history analytics via Purchase Data Lens and LTV Blueprint) and Digital Management Foundation Support (employee engagement surveys via Engagement Scope for Employee, generative-AI consulting via AI Sprint Loop, targeted phishing email training via Spear Phishing Shield, and corporate/recruitment website services). Underlying the service portfolio are several proprietary analytical frameworks — Stair-Step (cohort) Charts, Portfolio Analysis on a satisfaction-by-impact matrix, Pyramidal Survey Design, CX Score / 大学CX Score, and the LTV Blueprint retention methodology — paired with access to the WOW WORLD GROUP's WEBCAS email delivery platform (10,000+ installations) and Marketing Applications' MApps Survey panel for large-scale Japanese consumer research.

The firm monetizes primarily through project-based and retainer professional services engagements, sold via direct sales, co-hosted seminars, and referral through WOW WORLD GROUP sister companies, with no publicly disclosed pricing or self-serve product. Customer concentration is deliberately diversified across enterprise and mid-market clients in pharmaceuticals, food manufacturing, cosmetics, automotive, cloud, healthcare, entertainment, events, and local government; named logos include Amato Pharmaceutical, Attenir, Direct Ishii, Nitta Jozo, J-Oil Mills, Bike-O, Alibaba Cloud Japan, Carenet Tokushukai, Universal Music Labor Union, Iino Hall, and Kamikawa Town (Hokkaido). Thought leadership is the principal demand-generation channel: New Stream publishes a regular cadence of proprietary research reports (cheese purchasing, AI adoption, regional migration, osechi consumption, university alumni NPS) and a numbered "Email Marketing Practice" column series, leveraging the WOW WORLD email infrastructure for newsletter delivery.

The operating geography is Japan-only. Recent strategic emphasis has been on extending beyond email and web into social media (SNS lab works, 2025-11), broadening its survey IP from employee to customer engagement (Engagement Scope for Customer, 2024-10), and packaging applied AI capabilities into consulting offerings (AI Sprint Loop) and internal delivery methodology (AI-driven website rebuild in 2026-07 reduced build time to roughly one-third of the conventional approach).
