What （株）リソー教育 does
TOMAS, operated by Riso Kyoiku Group (（株）リソー教育), is a private Japanese one-on-one tutoring company operating 111 school branches across the Greater Tokyo metropolitan area (Tokyo, Kanagawa, Saitama, Chiba, and Ibaraki prefectures). The company's core offering is "complete one-on-one" (完全1対1) individual instruction delivered in private white-board-equipped booths, differentiated from the 1-to-2 or 1-to-3 formats common in the broader juku industry. Each student receives a custom "dream school reverse-calculation curriculum" (志望校合格逆算カリキュラム) built from the admission requirements of their specific target school, supported by a dedicated class advisor (教務担任) who manages progress and parent communication until the target school is reached. The company serves elementary students preparing for competitive middle-school entrance exams (the primary segment), junior high students preparing for high-school entrance or managing internal progression, high school students preparing for university entrance exams, and specialized medical-school applicants served through the MEDIC TOMAS sub-brand.
TOMAS operates a pure-service model with no proprietary software platform; instruction is delivered live by human instructors, supplemented by operational technology (self-study rooms, entry/exit management) and integrations with third-party tools including Monoxer for memory retention, atama+ for AI-driven assessment, and Sundai Diverse for video lectures. The portfolio includes four specialty sub-brands: MEDIC TOMAS for medical-school preparation, Spec.TOMAS for top-tier middle-school exam preparation, TOMAS Science Classroom for hands-on experiments, and Schola, an education media platform providing content marketing and top-of-funnel lead generation. Strategic content marketing includes a YouTube channel, parent-education columns in Kodansha's Cocoreco media, and regular events (school visit briefings, mock exams, free trial lessons).
The business model is direct-to-consumer with quote-based pricing: recurring monthly tuition for ongoing one-on-one instruction (primary revenue stream) supplemented by one-time seasonal intensive course fees (summer, winter, spring, mock exams). GTM is primarily inside-sales driven via phone hotlines (0120-65-1359) and website trial-lesson requests, augmented by extensive event-driven enrollment campaigns (school visit briefings, mock exams, science experiments). Prospect-to-enrollment conversion is supported by free 80-minute trial lessons and free learning consultations at all branches. Notable partnerships include Top School Academy (Plus One Education, announced September 2020) for one-on-one English instruction supporting overseas university admission pathways. The company is actively expanding its footprint with new branches in Urawa (Saitama) and Tsukuba (Ibaraki) opening in September 2026, plus a new MEDIC TOMAS branch in Ikebukuro opening in May 2026.

（株）リソー教育 competitors and assessment
Company assessmentBroad incumbents
- Benesse Corporation: Benesse is Japan's largest educational services holding company, parent of Tokyo Individualized Education, Shinkenzemi (home-study), and other tutoring/learning brands. It competes broadly with TOMAS through both individual tutoring and adjacent K-12 educational services across Japan.
- Kawaijuku (河合塾): Kawaijuku is one of Japan's largest nationwide exam prep institutions spanning elementary through university and medical school preparation. It is a broad incumbent in the same category as TOMAS, with significantly larger national scale but more group-format delivery.
- Sundai (駿台): Sundai is a major Japanese exam prep institution for high school and university entrance exams, also offering medical-school preparation. It is both a TOMAS partner (Sundai Diverse video courses) and a competitor for university-exam-prep students in Kanto.
Direct peers
- Waseda Academy (早稲田アカデミー): Waseda Academy is a major Tokyo-based K-12 exam prep chain with strong results at elite private middle and high schools. It competes with TOMAS across elementary, junior high, and high school entrance exam preparation in the same Kanto geography, including at the highest difficulty tiers.
- Meiko Gijuku (明光義塾): Meiko Gijuku is one of Japan's largest individual-tutoring franchise chains, offering 1-on-2 instruction nationwide. It competes with TOMAS on the individual-instruction format and broader tutoring segments, though at lower price points and broader curriculum scope.
- Sapix (サピックス): Sapix is Japan's leading group-format elementary-school entrance exam prep school, particularly dominant at the 御三家 (Kaisei, Azabu, Musashi) tier that TOMAS also targets with Spec.TOMAS. While Sapix uses group classrooms rather than 1:1, it competes directly for the same elite-school-outcome-driven families in Kanto.
- Kobetsu Kyoshitsu no Try (個別教室のトライ): Try is Japan's largest 1-on-1 / 1-on-2 individual tutoring franchise chain with nationwide coverage. It competes directly with TOMAS on the individual-tutoring format, though Try is more mass-market (lower price, broader curriculum) while TOMAS targets premium outcome-driven families.
- Tokyo Individualized Education (東京個別指導学院): Tokyo Individualized Education, operated by Benesse, offers 1-on-1 and 1-on-2 individual tutoring across Kanto and nationwide. It is one of TOMAS's most direct format-comparable competitors for individual instruction in the same geography, though positioned more broadly rather than at the elite-exam niche.
- Yotsuya Otsuka (四谷大塚): Yotsuya Otsuka is a leading Tokyo-based elementary entrance exam prep school serving students targeting top-tier private middle schools. It competes for the same Kanto families as TOMAS, particularly at the most-difficult exam tier that Spec.TOMAS addresses.
- Nichinoken (日能研): Nichinoken is one of Japan's largest elementary-school entrance exam prep specialists with nationwide reach. It directly competes with TOMAS for the same elementary-school-exam family segment in Tokyo, though its group-format classroom model differs from TOMAS's 1:1 approach.
