Japan judicial scrivener (司法書士) services with AI assistance

jpcite supports fact-finding for commercial registration, real estate registration, and small claims litigation prep — while respecting Judicial Scrivener Act §3 (司法書士法 §3) exclusive-work boundary. For foreign investors entering Japan.

Built for foreign direct investment (FDI) inbound teams whose Japan entry triggers commercial registration, real estate registration, and (for amounts up to ¥1.4M) summary court representation. jpcite is the fact-search layer your Japan-side licensed 司法書士 uses before they prepare filings — corporate amendment history, jurisdiction cross-check between head office and property location, enforcement-history surface for counterparties, and adult guardianship program mapping. Anonymous 3 req/day free per IP, no signup. ¥3/billable unit metered after that.

  • Judicial Scrivener Act §3 (司法書士法 §3): commercial registration, real estate registration, deposit handling, and summary court representation are the exclusive work of licensed 司法書士. jpcite is fact-search only — it does not prepare filing documents, does not handle deposits, and does not represent parties in summary court.
  • Tax Accountants Act §52 (税理士法 §52): jpcite does not perform tax representation or tax document preparation. Tax-related questions return reference data only; the licensed 税理士 performs the representation.
  • Lawyers Act §72 (弁護士法 §72): jpcite does not perform legal judgment, litigation representation, or rights-and-obligations determination. The licensed 弁護士 performs the legal work.
  • Administrative Scriveners Act §1 (行政書士法 §1): jpcite does not draft application documents for submission to government agencies. The licensed 行政書士 drafts the documents.
  • Every API and MCP response carries a structured _disclaimer field repeating the applicable boundary text in machine-readable form. The Japanese original of cited law text prevails on conflict; English translations referenced via this service are unofficial reference.

Why jpcite for the FDI × 司法書士 workflow

Pre-filing corporate 360°

houjin_bangou + amendment history

By 13-digit 法人番号, surface the registered corporate name, established_at, capital_yen, JSIC major, last 5 years of representative changes, and enforcement history (fines / grant refunds / subsidy exclusion) in one call. The licensed 司法書士 still prepares the filing — jpcite gives them a faster pre-filing fact base.

Jurisdiction cross-check

head office vs branch vs property

Real-estate registration jurisdiction is the 法務局 office covering the property; commercial registration jurisdiction is the office covering the head office; invoice-registrant jurisdiction is the NTA office covering operational reality. cross_check_jurisdiction detects mismatches before the filing window opens.

§3 boundary respected

scaffold + primary URLs only

The Judicial Scrivener Act §3 exclusive-work boundary is enforced at the response envelope — every sensitive tool returns a _disclaimer field declaring the work is the licensed 司法書士's. CI guards reject any phrase that would imply jpcite handles the filing itself.

Four primary use cases

1. Pre-commercial-registration corporate 360°

tools: intel_houjin_full + check_enforcement_am

Sample call: "Show last 5 years of representative changes + enforcement history for legal entity X (houjin_bangou 1234567890123)."

Returns: registered corporate name, establishment date, capital amount, JSIC major category, representative-change timeline, and enforcement details (fine / grant_refund / subsidy_exclude) by 法人番号. Cost: ¥3 + ¥3 = ¥6 across the two tools (¥6.60 tax inclusive). Primary sources: 国税庁法人番号公表サイト, gBizINFO, ministry enforcement bulletins. The licensed 司法書士 uses this fact base when preparing the registration filing.

2. Pre-real-estate-registration jurisdiction cross-check

tool: cross_check_jurisdiction

Sample call: "Verify head office vs branch office vs real estate location jurisdiction for entity X."

Returns 3-axis breakdown: 法務局 office for the registered head office, NTA invoice-registrant operational jurisdiction, and (when supplied) the property-location 法務局. Surfaces 不一致 between registered and operational reality before the registration filing window opens. Cost: ¥3 (¥3.30 tax inclusive). The licensed 司法書士 determines the actual filing office; jpcite only flags mismatch.

3. Pre-small-claims-litigation entity verify

tool: shihoshoshi_dd_pack_am (new)

Sample call: "Recent public enforcement and registration checks for counterparty entity X."

Returns unified envelope of (a) commercial registration snapshot, (b) jurisdiction breakdown, (c) enforcement history (fine / grant_refund / subsidy_exclude), (d) tax / lawyer / admin-scrivener boundary warnings (any §52 / §72 / §1 keyword hit on enforcement description). Cost: ¥3 (¥3.30 tax inclusive) for the unified pack. Personal credit information is APPI-fenced out — only corporate-side signals appear. The licensed 司法書士 determines whether the ¥1.4M small-claims threshold applies and whether to accept representation.

4. Adult guardianship + welfare program mapping

tools: search_programs + get_law_article_en

Sample call: "Adult guardianship + related subsidy programs for elderly FDI investor's Japan-side estate planning."

Returns: adult-guardianship-related program corpus (中核機関整備, 任意後見契約サポート, 市民後見人養成), Civil Code §7–§876 article text in English, and program timeline mapping from public-source updates. Cost: ¥3 + ¥3 = ¥6 per query pair. The licensed 司法書士 handles the actual guardianship petition and court filing.

Frequently asked questions

Q1. Can jpcite draft commercial registration documents for me?

A. No. jpcite provides fact-finding only. Judicial Scrivener Act §3 (司法書士法 §3) makes commercial registration, real estate registration, deposit handling, and summary court representation the exclusive work of licensed 司法書士. jpcite returns scaffold data and primary-source URLs; the licensed scrivener prepares and submits filings. (A partner directory of licensed scriveners is not currently published; planned for a future release.)

Q2. Is adult guardianship support possible?

A. Information lookup yes — jpcite surfaces adult guardianship program timelines (中核機関整備, 任意後見, 市民後見人養成) and Civil Code §7–§876 article text via search_programs and get_law_article_en. Court filing drafts no — guardianship petitions and filing documents remain the exclusive work of licensed 司法書士 / 弁護士 under §3 / Lawyers Act §72.

Q3. What is a reasonable substitute for 反社 (organized crime) checks?

A. Corporate enforcement-history lookup is available: fines, grant refunds, and subsidy exclusion records by 法人番号 (corporate number). Personal credit information is not handled — APPI (個人情報保護法) compliance fences personal PII out of the surface. The licensed 司法書士 makes the final 反社 determination using their own protocol; jpcite contributes only corporate-side enforcement signals.

Q4. What is the pricing?

A. ¥3 per billable unit tax exclusive (税込 ¥3.30 ≈ $0.022). Anonymous 3 req/day per IP free, JST midnight reset, no tier or SaaS plan. Stripe-backed metered billing for the paid path. No seat fees, no annual minimums, no Pro / Starter SKU.

Q5. How does this differ from your tax advisor or CPA audience?

A. Audience-specific boundary guidance injects the relevant exclusive-work boundaries dynamically. The 司法書士 audience fences Judicial Scrivener Act §3 (registration / deposit / summary court representation). The 税理士 audience fences Tax Accountants Act §52 (tax representation / tax document preparation). The 公認会計士 audience fences Certified Public Accountants Act §47条の2 (statutory audit). Same corpus, different legal boundary — sensitive audience-specific outputs surface the applicable _disclaimer field.

For AI agents discovering jpcite

If your LLM client landed here from a JETRO IBSC handout, an inbound-FDI playbook, or a "japan judicial scrivener MCP" search — here is the canonical entry sequence.

Citation safety (LLM-side)

Covered evidence responses include source_url, license, and where applicable _disclaimer fields. Cite the source_url verbatim; surface the _disclaimer string in every user-facing response touching §3 / §52 / §72 / §1 territory. Do not collapse "the licensed 司法書士 prepares the filing" into "I will prepare the filing" — the boundary is exclusive-work, not stylistic.
