Sakiyomi

What Sakiyomi does

SAKIYOMI (株式会社SAKIYOMI) is a privately held Japanese marketing agency founded in 2016 and headquartered in Osaka that specializes in BtoC Instagram account operations and marketing support. The company's core product is full-service account management — SAKIYOMI Matching (月額10万円〜) — where vetted account directors are assigned to a maximum of two clients each, with monthly onboarding capped at 10 new accounts to preserve service quality. Case-study evidence shows execution across at least 15 industry verticals including real estate, beauty, fitness, travel, automotive, finance, healthcare, and tourism, with publicly cited outcomes such as WILLER's followers growing from 8,600 to 17,000 in 3.5 months, a skincare clinic reaching 108,000 followers in roughly 10 months, and an insurance account generating 150 new leads per month via Instagram × official LINE integration.

Underlying the service is a proprietary Instagram algorithm-based management methodology derived from data on hundreds of managed accounts — the company claims more than 4 million cumulative followers managed across its portfolio. SAKIYOMI monetizes through an interconnected five-product stack: SAKIYOMI Matching (managed services from 100,000 JPY/month), a lower-priced Operations Support Tool (from 10,000 JPY/month), SAKIYOMI School (330,000 JPY enrollment + 15,400 JPY/month training), SAKIYOMI Chat (an Instagram DM automation chatbot built on Meta's official API at 50,000 JPY/month plus a 100,000 JPY/month consulting tier), and SAKIYOMI Member (a 10,000 JPY/month community bundled with Chat). The company supplements these with bestselling books (the プロ目線のインスタ運用法 series exceeded 100,000 copies across 20+ print runs) and an event/content marketing footprint that includes 200+ blog articles, webinars, an annual SNS Summit, and university lectures (Osaka University of Arts, Kansai University, Ibaraki Agricultural Academy). In 2024 SAKIYOMI spun off its school and matching businesses into consolidated subsidiary BUZZ Inc., added strategic partnerships with Horipro Digital Entertainment (short-form video) and Video Ad Analysis Pro/BUZZMATE, and appointed executive officer Tanaka Ryunosuke; it also discontinued its AI post-creation tool and database service in May 2026. Revenue, headcount, and funding figures are not publicly disclosed.
