Oh-Ebashi LPC & Partners

What Oh-Ebashi LPC & Partners does

Oh-Ebashi LPC & Partners (大江橋法律事務所) is a privately-held Japanese legal professional corporation (弁護士法人) founded in 1981 and headquartered in Osaka at Nakanoshima Festival Tower, with a second office in Tokyo's Marunouchi district. The firm is a full-service law practice delivering counsel across 19 practice areas, including Corporate/M&A, Crisis Management/Compliance, Intellectual Property, Business Recovery/Insolvency, Antitrust, Consumer Law, Dispute Resolution, Finance/Insurance, HR/Labor, Administrative Law, Tax, International Law with regional desks across Asia-Pacific, Europe, and the Americas, Life Sciences/Pharma/Medical, Personal Information/AI/IT/Digital, Sustainability/ESG, Energy/Infrastructure, sector-specific counsel, individual legal services, and pro bono activities. It serves large Japanese and multinational corporations, energy and infrastructure companies, and life sciences and healthcare firms, addressing complex transactions, regulatory compliance, cross-border matters, and dispute resolution. The firm reported headcount of 251-500 employees and a partner roster exceeding 45 named partners with specialized sub-practice expertise.

There is no proprietary software product; the offering consists entirely of professional legal services. Revenue mechanics are professional-services billing: hourly fees, fixed fees for specific matters, and retainer arrangements, with engagements typically structured as multi-year contracts. Distribution is sales-led: the firm markets through an extensive seminar/webinar program, publications including the Oh-Ebashi Newsletter, and direct client engagement from its Osaka and Tokyo offices. Thought leadership is reinforced through co-hosted programming with the International Bar Association, Japan Bar Association, Thomson Reuters Japan, Business & Law, and LegalOn Technologies' Legal Learning platform. Geographic expansion is active, exemplified by the Jakarta Desk launched on December 2, 2025. The firm has no disclosed funding, no parent company, and no subsidiaries; ownership and partner-capital structure typical of a Japanese 弁護士法人 are not publicly broken out.
