What AZX Professionals Group does

AZX Professionals Group is a privately held Japanese multi-disciplinary professional services firm founded in 2001 in Tokyo by Kenji Hayashi, Katsunari Gotoh, and a tax accountant partner named Yamada. Operating under the tagline "Super Highway for the Future," the firm is structured as a group of five core operating subsidiaries — AZX総合法律事務所 (law), AZX総合会計事務所 (tax/accounting), AZX国際特許事務所 (patent), AZX社会保険労務士事務所 (labor/social insurance), plus AZX Group and AZX Business Support — delivering an integrated "one-stop" professional service model. The firm does not develop technology products; its offering is human-delivered advisory across legal, tax, accounting, labor, and patent disciplines.

AZX serves four primary customer segments: aspiring entrepreneurs, growth-stage startups and venture companies, listed companies, and venture capital firms. Over 25 years it has supported 7,000+ venture companies, contributed to 190+ IPOs, and handled 6,000+ fundraising support cases across sectors including IT, biotech, fintech, entertainment, manufacturing, and food & beverage. In addition to standard quote-based professional services, AZX operates ecosystem-building products: a ¥1,000/month "Startup Special" subscription for qualifying early-stage startups, a free business model legality review service, free online consultation, and "Series AZX," a free investor-introduction program. It also offers KEISUKE, a standalone contract-drafting template service. The firm operates from Tokyo (Chiyoda-ku headquarters) and Fukuoka (Tenjin Front Square), serving clients domestically across Japan.

AZX's revenue model is professional services fee-based, with quote-based pricing for standard engagements and a near-zero-cost subscription tier used as a customer-acquisition funnel. The go-to-market motion is sales-led and relationship-based, supported by a content-marketing engine (blog, YouTube "Startup Legal Consultation," document template library, glossary) and free consultation entry points. The firm is independently owned by its partners with no disclosed private equity, venture, or corporate parent ownership.
