TREE

What TREE does

TREE Inc. (株式会社TREE) is a privately held Japanese tutoring operator founded on November 5, 2013, and headquartered in a single physical classroom in Toshima-ku, Tokyo, near JR Yamanote/Toei Mita Sugamo Station. The company delivers customized university entrance exam preparation to high school students (primary segment) and middle school students (secondary segment), with explicit positioning for students balancing club activities with academics and for both recommendation/AO and general admission pathways. Its core differentiator is a fully individualized, made-to-order curriculum built jointly by certified professional instructors and each student, rather than a standardized group-lecture format.

The service portfolio centers on a "lecture-exercise" hybrid delivered in-person, structured as subscription-based weekly attendance plans (Weekly 1-Day at 33,000 yen/month and Weekly 2-Day at 63,800 yen/month, tax-inclusive) plus pay-as-you-go individual tutoring with professional instructors (from 17,600 yen/hour) and student tutors (8,800 yen/hour). An enrollment fee of 22,000 yen is currently being waived under a promotional campaign. Classes operate Mon/Wed/Fri 16:00–22:00 (instruction from 17:00), and the company markets per-hour effective cost as low as 1,339 yen, contrasting with approximately 20,000 yen per 60-minute session at major personal tutoring chains. Acquisition runs through a low-friction, direct-to-consumer motion: free trial lessons and learning consultations, plus phone and email inquiry, with no paid digital advertising or online delivery.

TREE discloses no technology platform, no app, no API, no software, no AI capabilities, no patents, no trademarks, no partnerships, and no funding. All operations are conducted at the single Toshima-ku location by a small, undisclosed team led by Classroom Director/Career Consultant Masako Nobuhara. Revenue, headcount, and student enrollment figures are not publicly disclosed, and the company has held no funding rounds and has no parent or holding entity. The business model is recurring monthly subscriptions supplemented by unit-priced individual tutoring, with customer concentration risk primarily geographic (one Tokyo neighborhood) rather than logo-driven.

Broad incumbents

• 城南予備校 (Jonan Yobikō): Tokyo-based prep school group with classroom and correspondence offerings for university entrance exam preparation. Comparable target market and geography (Tokyo, high school students), but competes at larger scale via standardized prep formats rather than TREE's bespoke single-site model.
• 河合塾 (Kawai Juku): One of Japan's largest university-entrance preparatory school chains, offering group lecture courses, mock exams, and tutoring. Overlaps with TREE on the target outcome (university entrance exams) and student persona, but operates as a mass-market group-lecture model across many locations rather than a single customized classroom.
• Benesse Corporation (進研ゼミ): Major Japanese educational services group offering correspondence courses, magazines, and school-services for K-12 including high school university-prep. Overlaps on the high school university-prep outcome but delivers primarily through print/digital content rather than in-person tutoring like TREE.
• 代々木ゼミナール (Yoyogi Zemi): National prep school chain focused on university entrance exam preparation through group lecture courses. Comparable on target student and outcome (high school students preparing for university entrance), but competes via standardized lecture formats at national scale rather than individualized curriculum.
• 早稲田アカデミー (Waseda Academy): Prep school chain targeting top-tier Japanese university entrance, particularly Waseda, Keio, and other elite schools. Directly overlaps with TREE on its documented Waseda/Keio/Sophia recommendation-admission outcomes, but operates at multi-location scale with group instruction rather than single-site customized delivery.

Emerging players

• Atama+: AI-driven personalized learning platform for middle and high school students preparing for university entrance exams in Japan. Competes with TREE for the same student persona and outcome, but via digital adaptive instruction rather than in-person classroom delivery, representing a technology-substitution threat.
• すらら (Surala): Adaptive online learning platform used by Japanese juku and schools for individualized K-12 instruction, including exam preparation. Comparable in the personalized-learning thesis but delivered via software rather than TREE's in-person instructor-led model.
• スタディサプリ (Study Sapuri) by Recruit: Online university-entrance prep service offering video lectures and adaptive exercises for high school students at low subscription price points. Overlaps with TREE on subscription pricing model and high-school exam-prep audience, but competes via scalable digital delivery rather than physical classroom instruction.

Direct peers

• Try Group (家庭教師のトライ): Japan's largest personal-tutoring chain, providing one-on-one instruction across subjects including university entrance exam preparation. Directly comparable in customer segment (high school exam-prep students), in-person delivery, and emphasis on individual instruction, but at much larger scale and using primarily student tutors.
• 明光義塾 (Meiko Gijuku): Large juku chain in Japan operating individual-style tutoring classrooms focused on individualized instruction rather than large group lectures. Comparable in service format (in-person, customized, classroom-based) and target audience (K-12 exam preparation), though it operates hundreds of franchise locations versus TREE's single site.
