A 1-Page Comparison of "Opening a Business in Tokyo vs Osaka" -- 15 Industries x 47 Prefectures Comparison Pages Added to 'Hojokin Sagasu AI' Business Simulator
X-HACK Inc. updated the business simulator for its free tool "Hojokin Sagasu AI," adding features that allow cross-comparison of 15 industries across 47 prefectures. The update also improves data reliability by auto-tracking revisions to official prices, providing robust decision-making support without requiring registration.

X-HACK Inc. (Headquarters: Shinagawa-ku, Tokyo; Representative Director: Shinsuke Matsuda) has added an industry-by-prefecture comparison page feature to the business simulator of its free subsidy/grant search service, "Hojokin Sagasu AI" (https://hojokin-hub.ai).
Decisions such as "Opening an izakaya in Tokyo vs. Osaka" or "Opening an izakaya vs. a cafe in Fukuoka" can now be compared side-by-side on a single page.
Simultaneously, the entire simulator has undergone a major update centered on the dual axes of "Data Reliability x Decision Support." This includes enhanced visuals by industry, a redesign of pessimistic scenarios by industry type, and an automatic tracking process for nursing care remunerations and official childcare prices.
Development Background: No basis to judge "which region" and "which industry" to open a business in
In April 2026, "Hojokin Sagasu AI" released a business simulator supporting 15 industries (https://hojokin-hub.ai/tools/simulators). However, the following feedback was received from people actually considering opening a business:
"I want to see at a glance whether I would have a higher net income opening in Tokyo or Osaka."
"If I start an izakaya or a cafe with the same budget, I want to know which one will cross the break-even point faster."
"Is it realistic for gyms and cram schools to show a '40% member cancellation' in the pessimistic scenario?"
"Are the unit prices for licensed childcare and outpatient nursing care reflecting the latest values in the simulator?"
Standalone pages (industry x prefecture) cannot support the relative comparison of "Should I choose A or B?" which business operators ultimately want to know.
Furthermore, using uniform coefficients for all industries or manually rewriting code for every price revision poses the risk of the data losing freshness over time.
This update resolves these issues all at once.
Added and Enhanced Features
1. Industry x Prefecture Pair Comparison Pages
We added pages where you can compare the same industry in two different prefectures, such as "Izakaya Startup Tokyo vs. Osaka."
Side-by-side display of monthly sales, initial costs, net monthly income, months to break even, average rent, etc., highlighting the differences.
Initially published 450 URLs = 30 representative pairs (selected based on economic scale, proximity, and national scope) x 15 industries.
Automatically generates decision-making guides on each page like "People like this should choose Tokyo" or "People like this should choose Osaka."
2. Industry Pair x Prefecture Comparison Pages
We added pages for comparing different industries in the same region, such as "Izakaya vs. Cafe in Fukuoka" or "Beauty Salon vs. Barber in Osaka."
Initially published 940 pages = 20 representative industry pairs (selected based on competition, substitution, and proximity) x 47 prefectures.
Initial costs, estimated required floor space, and the number of candidate subsidies are included in the comparison.
3. Redesigned Pessimistic Scenarios by Industry Category
The previous uniform "customer footfall x 0.6 for all industries" has been separated into 4 profiles based on industry categories.
Flow type (dining, beauty, osteopathic clinics, etc.): Footfall x 0.60 (off-season level, same as before)
Stock membership type (gyms, cram schools, monthly guesthouses): x 0.80 (reflecting an actual annual cancellation rate of 20-30%)
Official price regulation type (licensed childcare, outpatient nursing care): x 0.90 (reflecting the structure where local governments fill empty spots)
Non-official price type (unlicensed childcare, etc.): x 0.70
This avoids the pessimistic values on the ranking page from becoming "unrealistic numbers at the level of bankruptcy," thereby raising the reliability of the simulator.
5. Automatic Tracking Process for Nursing Care Remunerations and Official Childcare Prices
Nursing care remunerations are revised by the government once every three years (next in April 2027), and official childcare prices are revised every April and October.
The biggest challenge in this area is that if these are revised but left as old numbers, the simulator's estimates gradually deviate from reality.
In "Hojokin Sagasu AI," we built a system where each of these public price figures is managed with a "Source," "Last Confirmed Date," and "Next Scheduled Revision Date," automatically triggering an alert about a month before the revision.
The next revision is the nursing care remuneration in April 2027. We are running operations ahead of schedule for that.
Records "when" and "based on which public document" updates were made, structurally eliminating the risk of continuing to post outdated numbers.
Centrally manages the numbers referenced by the simulator, rankings, and related articles to ensure consistency across all screens.
6. Enhanced Compatibility for AI Search Engines
We adjusted the metadata structure to be easily cited by AI search engines like ChatGPT and Gemini, strengthening data provision to various AI tools.
