What Eight does
Eight Inc. (株式会社エイト) is a privately held Tokyo-based digital marketing agency founded in 2020 and headquartered in Shinjuku, Tokyo, with 51–100 employees. The company provides a full-service digital marketing offering to Japanese SMBs and mid-market enterprises across four business lines: web production (corporate sites, landing pages, EC sites), web consulting (SEO consulting, article creation, article outline drafting, backlink acquisition, MEO, L-Step/LINE marketing), media operations (previously including 'The Leader' president interview media, divested October 2024), and internet advertising (Google, Facebook, TikTok, SNS). Additional service lines cover TikTok/YouTube/Instagram/Twitter account management, TikTok ad video production, and video editing/filming.
The company's core technology is a methodology-driven SEO and web marketing stack rather than proprietary software: a triple-check editorial quality system (director outlines, senior director review, vetted writer execution), a white-hat backlink acquisition process using Ahrefs-based Domain Rating tiering, and an owned-media portfolio of dozens of niche web properties that rank for competitive keywords and serve as a living proof-of-concept for the firm's SEO capabilities. Pricing is unit-economics based: SEO retainers run ¥300,000–¥500,000/month with minimum 6-month terms, article creation is ¥20,000–¥80,000 per article, TikTok management is ¥200,000/month, and backlink acquisition is performance-based at ¥10,000–¥100,000 per item by domain rating.
Eight monetizes through a hybrid of monthly retainers (subscription_recurring), professional services fees, and one-time project fees, sold primarily via direct B2B sales consultations, a free-dial contact line (0120-193-621), and self-service website inquiries. The company operates exclusively in Japan, with no disclosed external funding, no parent company, and no public listing.
