jpcite for foreign investors (FDI)

1. "What's the WHT on intercompany dividends from Japan to my US parent?"

The planned tax-treaty surface (get_tax_treaty MCP tool / GET /v1/en/tax_treaty/... — on the roadmap, not yet live) will return the parent-dividend rate (5% under the 10%-or-more / 12-month rule, 0% under the 50%+ rule per the 2019 protocol) plus the article reference, sourced from and audited against the MoF treaty list — not a blog post.

2. "Which Japanese subsidies can a foreign-owned KK apply for?"

The Japanese permissive default is 'silent on foreign capital' — most national programs are open. Use search_programs(foreign_capital_eligibility="eligible") to surface the explicitly-FDI-targeted set: METI Inward FDI (対日直接投資), JETRO IBSC, J-Bridge, Global Acceleration Hub, J-Startup.

3. "Is this a 外為法 (FEFTA) prior-notification sector?"

Look up by JSIC industry code via the foreign-direct-investment endpoint to see whether the target Japanese company sits in one of the ~155 designated prior-notification (事前届出) sectors (national security, dual-use tech, critical infrastructure, weapons, nuclear, aerospace, cyber, semiconductors, mineral extraction, etc.). Check before the 30-day filing window.

4. "Show me the English text of the 外為法 (FEFTA) article on prior notification"

Law metadata and article text cover statutes such as the Companies Act (会社法), Corporation Tax Act (法人税法), Income Tax Act (所得税法), Foreign Exchange and Foreign Trade Act (外為法), Antimonopoly Act (独占禁止法), Act on the Protection of Personal Information (APPI, 個人情報保護法), and Financial Instruments and Exchange Act (金融商品取引法) — call the live get_law_article_am MCP tool for article text (Japanese). English-translation output and a dedicated English law-search tool draw on the e-Gov 日本法令外国語訳 corpus (CC-BY 4.0) and are on the roadmap. The Japanese original prevails on conflict.

5. "Is <houjin_bangou> a registered qualified-invoice issuer?"

Call search_invoice_registrants(houjin_bangou="...") against the 13,801-row delta + monthly 4M-row NTA bulk corpus. Critical for foreign-supplier compliance: invoices from non-registered issuers are not deductible for input-tax credit under the qualified-invoice system.

6. "What's the enforcement / adoption track record on this acquisition target?"

By 13-digit corporate number (法人番号), join 1,185 enforcement cases + 2,286 subsidy adoption rows + 13,801 invoice-registrant rows + the houjin master in one call (get_houjin_360). Drop into your DD pipeline.

Python (commercial, ¥3/billable unit)

import httpx
H = {"X-API-Key": "jc_..."}

# 1. WHT dividend rate Japan -> US parent
r = httpx.get(
 "https://api.jpcite.com/v1/tax_rulesets/search",
 params={"q": "租税条約 米国"},
 headers=H)
print(r.json()["results"][0]["primary_name"], r.json()["results"][0].get("source_url"))

# 2. FDI-relevant Japanese subsidies
r2 = httpx.get(
 "https://api.jpcite.com/v1/programs/search",
 params={"q": "対日直接投資 OR JETRO OR 外資", "limit": 10},
 headers=H)
for row in r2.json["items"]:
 print(row["name"], row["source_url"])

Issue API keys from your dashboard. Stripe-backed metered billing. The search query 対日直接投資 OR JETRO OR 外資 (inward FDI / foreign capital) is passed to the API verbatim in Japanese — keep the Japanese keywords, since a translated query matches no rows.
