Hibiya Park Law Offices

What Hibiya Park Law Offices does

Hibiya Park Law Offices is a privately held Japanese law firm founded in 2016 and headquartered at the Hibiya Marine Building in central Tokyo (Chiyoda-ku), with an additional presence indicated in Osaka. The firm fields approximately twenty legal professionals — a founding partner, eleven partners, five associates, two special counsel, and one advisor — organized around a broad corporate practice that spans corporate law and governance, intellectual property (patent, trademark, copyright), competition/antitrust, sports, media and entertainment, financial transactions, and litigation and dispute resolution. Its positioning is dual-track: serving as a strategic advisory partner for transactions while acting as an aggressive advocate in disputes, with a stated emphasis on large-scale damages matters, independent investigation committees, and corporate compliance/risk management.

The firm's core 'product' is bespoke legal advice delivered through engagement-based professional services, billed under hourly fees, fixed fees, or retainer arrangements, with no publicly disclosed fee schedule. Underlying 'technology' is the partner bench's domain expertise, supplemented by participation in international and domestic professional networks — most notably LEGUS (International Network of Law Firms) for cross-border matters — and topical practice-area publications (e.g., system development disputes, digital content and terms of use).

Go-to-market is enterprise field sales through direct partner-led relationships with corporate clients in regulated industries, supported by top-of-funnel content marketing via attorney publications, mid-funnel seminars (Japan Industrial Management & Accounting Institute, Osaka Chamber of Commerce and Industry), and visibility from third-party rankings such as The Best Lawyers in Japan 2026. There is no software, product, or technology platform component to the business; revenue is derived entirely from human legal service delivery.
