What 弁護士ドットコム does

Bengo4.com, Inc. (弁護士ドットコム株式会社) operates Japan's largest consumer-facing legal Q&A and lawyer-matching platform, founded in 2005 and headquartered in Tokyo. The flagship bengo4.com portal provides free public legal Q&A (みんなの法律相談, with 1,496,525 cumulative consultations), a nationwide lawyer directory of 24,019 member lawyers searchable by all 47 prefectures and 14 practice areas, a bulk-quotation matching service (一括見積り), a chat-based legal consultation channel (チャット法律相談, currently scoped to divorce and family issues), and a beta telephone hotline (弁護士ドットコム ホットライン β版, 050-1793-2750). Around this core platform the company runs a daily-updated legal news vertical (弁護士ドットコムニュース) that drives organic SEO traffic and brand authority, plus a curated archive of 1,456 summarized legal Q&A articles across 73 pages and 15 categories.

The technical stack centers on the AI-powered リーガルブレインエージェント (Legal Brain Agent), which performs knowledge retrieval, cross-referencing, citation verification, and cross-sectional research over proprietary Japanese legal corpora — including exclusive publisher content from the Financial and Economic Research Association's "6000 Lectures on Legal Measures for Financial Institutions" (6 volumes, ~8,700 pages) and Tachibana Shobo's Police Science Journal. A separate AI product, AI炎上チェッカー, applies NLP-based reputational-risk screening to user-submitted drafts. No public/partner-facing developer API is documented, so AI capabilities are delivered entirely through Bengo4.com's owned web and microsite experiences (chat.bengo4.com, article-archives.bengo4.com, safety-checker.bengo4.com, event-bengo4.com).

The business model combines a freemium consumer subscription (premium tier at "the cost of a cup of coffee" unlocking unlimited expert lawyer answers), per-lead / per-transaction matching fees from lawyers receiving 一括見積り requests, recurring managed services sold to the 24,019 registered member lawyers (lead access, profile tools, AI Legal Brain research), and subscription/one-off revenue from digital legal-book publishing partnerships. Distribution is single-country (Japan, all 47 prefectures) through owned web properties, a dedicated lawyer login portal for inside-sales onboarding, and a cross-promoted sister-brand ecosystem that includes CloudSign (e-signature), Zeiri4.com (tax-accountant matching), BUSINESS LAWYERS (corporate legal), three vertical portals (inheritance, corporate, divorce), 弁護士ドットコムキャリア (legal careers), UNITIS (legal matching), and the Gen AI EXPO online event platform.
