AutonoMath for SMB owners
Ask the LINE bot "are there any subsidies for my industry?" — no setup, no app, 10 free questions per month. The LINE bot launches 2026-05-06 (waitlist open; we'll email when it's live).
Designed for owner-operated small businesses (the owner, a spouse, a bookkeeper). Add the LINE bot and search 13,578 subsidies and 108 loans in plain language. Question 11 onward is ¥3. An optional connector routes you to a matched certified support organization, tax advisor, or administrative scrivener. If you'd rather not wait, the API + MCP (¥3/req) is already available.
Why AutonoMath
99%+ primary-source coverage
National, prefectural, municipal originals

Connect to a matched professional
Certified support organization, tax advisor, administrative scrivener
For programs with complex paperwork, we match you to a professional advisor by region and industry. The user pays nothing for the introduction — the advisor pays ¥3,000 (tax exclusive) only on a closed engagement.
Primary use cases
1. Restaurant owner: "What subsidies are available in Tokyo?"
Send prefecture and industry to LINE. You'll see Tokyo SME Promotion Public Corporation grants, the small-business sustainability subsidy, and IT-introduction subsidies (POS / order systems), each with the source URL and application deadline.
2. Manufacturer (~10 staff): "Subsidies for capital investment"
Top 5 includes monozukuri subsidy (SME Support Japan), business-restructuring subsidy (METI), and energy-saving subsidy (MOE). The exclusion-rule view tells you "this and that can't be combined".
3. Sole proprietor: "Special measures for tax filing"
Surfaces blue-form filing special deduction, the Small Enterprise Mutual Aid system, iDeCo, and similar measures. Pulls relevant rulesets from the 35 NTA-sourced tax_rulesets.
4. Retailer: "Japan Finance Corporation loan terms"
Out of 108 JFC products, surfaces loans that match your industry and size. Transparent across three axes: collateral / personal guarantor / third-party guarantor.
5. From application question to professional advisor
Send "I'd like help filing" in LINE and we return a list of advisors that match your region and industry. Compare profiles, specialties, and rate cards, then contact directly.
