Authense Holdings

What Authense Holdings does

Authense Holdings LLC is a Tokyo-based private holding company that functions as the strategic and organizational hub for the Authense Professional Group, a multi-disciplinary professional services platform anchored by Authense Law Office (Authense LPC), a full-service Japanese law firm founded in 2005 by lawyer Yuichiro Motoe. The operating group spans six core professional entities — law, tax accounting (Authense Tax Corporation), patent and trademark (Authense Patent Corporation), social insurance labor consulting (Authense SR), judicial scrivener services, and business consulting (Authense Consulting) — plus a capital partnership with Universal Sports Japan, Japan's largest football player agency. Authense employs 251-500 professionals across seven offices in the Tokyo metropolitan area and Osaka, including 62 lawyers (with 2 seconded to government ministries), 4 CPAs/tax accountants, 7 patent attorneys, 2 social insurance labor consultants, 6 administrative scrivener examination passers, and 165 support staff.

The firm's revenue model rests on four primary streams: (1) retainer-based corporate legal advisory services spanning 22+ practice areas (M&A, compliance, IP, labor, antitrust, regulatory, dispute resolution, etc.) sold via annual subscription plans bundled with electronic contract services; (2) the Houmu Cloud (法務クラウド) legal function outsourcing service, a productized monthly subscription offering ready-to-deploy legal talent to corporate legal departments; (3) individual legal services across wills/inheritance, defamation, traffic accidents, family law, victim support, and criminal matters; and (4) patent and trademark registration services, including the Cotobox online trademark platform that achieved over 30,000 cumulative users and ranked No. 1 in Japan for trademark filing volume in 2021. Go-to-market combines enterprise field sales, thought-leadership content marketing (THE INNOVATORS magazine, webinars, YouTube, email newsletters, social channels), and in-person plus online consultations.

Strategic positioning combines traditional professional service expertise with selective technology enablement and a group-wide one-stop service proposition. The firm is led by representative Taichiro Motoe (also founder of publicly listed Lawyer.com), and the group's most significant capital deployment to date is the February 2026 acquisition of a 50.002% majority stake in J1 League soccer club Shonan Bellmare, with co-investors Fujita Corporation and Amada Co., signaling an evolving holding-company strategy that extends beyond professional services into sports and lifestyle asset ownership. Authense Holdings has not publicly disclosed revenue, operates without external funding rounds, and reports through private corporate entities with no public listing.
