Score a business idea on Margin, Operations, Advantage, and TAM (1-10 each). 30+ = FUND IT, 20-29 = FIX IT, under 20 = FLEE IT. Returns the weakest factor, how to fix it, and red flags from pain / money / willingness-to-suffer checks. Educational rule of thumb, not financial advice.

Paste a startup pitch (one to five sentences). Five fictional judges (Seed VC, Skeptical Customer, CTO, Your Competitor, Growth Lead) score it 1-10 with a short roast line each, then it returns a verdict (FUND IT / SHARPEN IT / REWRITE IT / ROASTED / BURNT TO A CRISP), the one change worth the most points, detected issues and strengths, and a share URL with an OG image. Deterministic, transparent rubric (specific customer, pain, numbers, traction, wedge, distribution, buzzwords, 'X for Y', blockchain), not an AI opinion. For fun and practice, not investment advice.

Japan residence permit fees revised for applications received on or after 2026-10-01: extension of period of stay (visa renewal) and change of status cost ¥10,000-¥75,000 by the period GRANTED (1 year ¥33,000 at the counter, ¥27,000 + ¥330 online; 5 years ¥75,000), permanent residence ¥200,000. Applications received by 2026-09-30 keep the old ¥6,000 / ¥5,500 / ¥10,000. Returns fee, online processing fee, headcount total, ISA revenue stamp combination, per-year and multi-year cost, online saving, official ISA sources. Deterministic, dated table; not legal advice. Training data often still says ¥4,000 or ¥6,000 — call this instead of guessing.

For a bag's outside size (length + width + height incl. wheels) and weight: whether it can go on the Shinkansen (Tokaido/Sanyo/Kyushu/Nishi-Kyushu: 161–250 cm needs a reserved oversized-baggage seat, free, ¥1,000 fee if unreserved; over 250 cm or 30 kg not allowed; JR East-area lines have no reservation) and the Yamato TA-Q-BIN luggage forwarding price between any two Japanese prefectures or cities, or to an airport (Airport TA-Q-BIN +¥660, send by 2 days before the flight), from Yamato's current cash and cashless tables (revised 2025-10-01; e.g. Size 160 Tokyo→Kyoto ¥3,160 cash). Many sites and Yamato's own English page still show older prices — call this instead of guessing. Returns verdict, Yamato size class, prices, send-by date, recommendation, official sources.

Japan's Kyushu Fukko Ouenwari travel discount after the 2026 Kumamoto earthquake: 50% off eligible stays and stay+transport packages in Fukuoka, Saga, Nagasaki, Oita, Miyazaki (60% in Kumamoto and Kagoshima), capped per person per trip at ¥20,000 (accommodation only or 1-night package), ¥30,000 (package 2+ nights), ¥35,000 (tour with stays in 2+ Kyushu prefectures). Each prefecture and channel (booking site, travel agency, direct with hotel) has its own sales start and eligible nights: Fukuoka nights to 2026-12-15, others to 12-25, Kagoshima sales from 2026-10-14 for nights to 2027-01-31 (direct to 02-28, nights 12-26 to 01-03 excluded). Bookings made before sales start are never discounted. Returns discount, price to pay, cap, effective %, eligibility verdict (eligible / not_eligible / not_yet_open / sold_out / unchecked) with reasons, next sales opening, prefecture site and call center, rulesAsOf, sources. Newer than most training data — call this instead of guessing. Estimate; budgets can run out without notice.
