Seiha Network

What Seiha Network does

Seiha Network Co., Ltd. (セイハネットワーク株式会社) is a Japanese private educational services company founded in 1985 by Sakaguchi Masami and headquartered in Hakata, Fukuoka. The company operates under Seiha Holdings Co., Ltd. and runs the largest shopping-center-embedded children's English education network in Japan, with 500+ Seiha English Academy classrooms and a broader group portfolio of 1,300+ classrooms across all 47 prefectures. Its flagship product is team-taught children's English lessons (paired foreign native-speaker and Japanese instructors) for ages 0 to junior high school, structured into Hello Club (0–3 yrs), Preschool (3–6 yrs), Elementary A/B (grades 1–6), Junior High (grades 7–9), and Eiken test-prep courses. Monthly tuition ranges from ¥5,940 to ¥10,670 per course, supplemented by enrollment fees, annual membership fees, and one-time materials fees.

The company runs a diversified group of sub-brands covering adjacent children's verticals: Seiha Dance Academy (hip-hop, jazz, K-POP), 88-kun Soroban (abacus/arithmetic), Robo-done (LEGO robotics and programming), Try Plus (tutoring), Seiha English Park (experiential facility), and Kitakyushu Global Gateway (mission-based English immersion). Digital products include the SEIHA NET enrollment/management app, Be Ambitious home-learning app (drills, listening tests, QR treasure cards), Friends Time (online lessons connecting Japanese students with Cebu-based instructors), and Student Link (lesson video library). UP Talk extends online delivery, and short-term overseas study programs operate in Cebu, Philippines.

The revenue model is predominantly direct-to-consumer monthly recurring tuition, augmented by one-time enrollment and materials fees, annual facility fees, and ancillary professional-services revenue (instructor dispatch to kindergartens/elementary schools/municipalities, study-abroad programs, Philippine HR dispatch). FY2024 disclosed revenue is 10.2 billion JPY across 88,000+ group students and 2,740 employees. Acquisition and growth in adjacent educational verticals, B2B instructor dispatch, and cross-border study programs form the principal expansion vectors beyond core in-person classroom lessons.

Targeted preschool and elementary-age children.
• Shopping Center Operators (AEON, Ito-Yokado, Lalaport, Ario, etc.)coreChannel Partner/ Reseller/ DistributorSeiha Network's primary real estate and distribution partnership. Approximately 870 of 1,300 total group classrooms are located inside large shopping centers owned by major retail chains. This gives Seiha access to high foot-traffic locations where families already shop, providing visibility and convenience that supports direct enrollment. No revenue-sharing structure described — Seiha appears to lease retail space within malls.
