Japanese Stock
Research Tools
Practical checklists, research prompts, and screening workflows for self-directed investors researching Japanese listed companies. These tools are designed to reduce missed disclosures, separate facts from assumptions, and make the research process easier to repeat.
No paid products are currently available.
The tools listed on this page are being developed and tested
through real research workflows. Free guides and practical examples
are available while the templates are being prepared.
A practical research notebook, not an investment advisory service
This project documents how an individual investor in Japan uses AI, TradingView, and official company disclosures to research Japanese stocks.
The goal is not to provide an answer. It is to improve the process used to reach one.
I use generative AI to organize information and challenge my assumptions, but I do not treat AI output as a conclusion.
Before making a decision, I try to verify the information through TDnet, kessan tanshin, earnings presentations, company IR pages, securities reports, charts, and market data.
The final decision remains my own.
Research the company before forming a strong opinion
The tools are built around three basic disciplines.
Verify primary sources
Check company disclosures, earnings releases, presentations, and official filings instead of relying only on summaries or social-media commentary.
Separate evidence from interpretation
Distinguish confirmed facts from investment hypotheses and information that has not yet been verified.
Record reasons to pass
A useful research log should preserve concerns, missing information, invalidation conditions, and reasons not to buy.
Three tools designed for repeatable Japanese stock research
Each tool is based on research tasks that repeatedly appear when screening and reviewing Japanese listed companies.
Japanese Stock Research Checklist
A structured worksheet for reviewing official disclosures, financial changes, valuation, market data, catalysts, risks, and invalidation conditions.
Planned sections
- TDnet and company IR review
- Kessan tanshin earnings changes
- Financial position and cash flow
- Valuation and current price position
- Volume, liquidity, and market supply-demand
- Catalysts, risks, and missing information
- Reasons to buy, wait, or pass
- Invalidation conditions and next review date
AI Counterargument Prompts
A prompt set designed to make generative AI challenge an investment thesis instead of simply agreeing with it.
Planned sections
- Identify weaknesses in the investment thesis
- Test whether the catalyst may already be priced in
- Generate earnings downside scenarios
- Examine liquidity and supply-demand risks
- Find missing primary-source information
- Define thesis invalidation conditions
- Separate facts, inferences, and unknowns
- Prepare questions for the next review
Pine Screener Workflow Pack
A screening workflow that connects candidate discovery in TradingView with official disclosure checks and watchlist management.
Planned sections
- Pine Screener code
- Setup and parameter examples
- Candidate filtering rules
- Liquidity and exclusion checks
- Post-screening disclosure review
- False-positive and rejected examples
- Watchlist monitoring sheet
- Reasons to continue watching or remove a stock
Screening is only the beginning
A stock appearing in a screener is not a recommendation. It is simply a candidate for further research.
Find candidates
Use TradingView, Pine Screener, market themes, or unusual price and volume activity.
Verify disclosures
Review TDnet, kessan tanshin, company presentations, IR pages, and statutory filings.
Challenge the thesis
Examine valuation, expectations, downside scenarios, liquidity, catalysts, and missing information.
Record the decision
Document why the stock was bought, rejected, or left on the watchlist for another review.
Fact, inference, and unknown should not be mixed together
This classification is used throughout the research tools to reduce false confidence.
Confirmed information
Information verified through company disclosures, earnings reports, official IR materials, filings, charts, or identifiable market data.
A research hypothesis
A possible interpretation of the facts, including catalysts, market recognition, future buyers, and supply-demand dynamics.
Not yet verified
Missing documents, unclear data, outdated information, contradictory sources, or questions that still require research.
Free resources first, paid tools only when they save meaningful work
The free version should remain useful on its own. A future paid version would focus on repeat use, structured records, and time-saving features.

Useful for independent research, not for outsourcing decisions
These tools may be useful if you:
- Research Japanese companies independently
- Want to understand Japanese primary disclosures
- Use AI as an assistant rather than a decision-maker
- Want to record both positive and negative evidence
- Need a repeatable post-screening workflow
- Research Japanese small- and mid-cap stocks
These tools are not designed for you if you:
- Want a list of guaranteed winning stocks
- Expect automatic buy and sell signals
- Want AI to make investment decisions for you
- Do not intend to verify official information
- Expect investment results to be guaranteed
- Are looking for individualized financial advice
Start with the free research guides
These articles explain the workflow behind the tools. Review the free material first to see whether this research approach fits the way you invest.
The tools are being tested before release
I am currently organizing the checklists, prompts, and screening materials used in my own research. The first public release is expected to be a free sample of the Japanese Stock Research Checklist.
Any future paid product will focus on research organization and decision support. It will not contain personalized advice, guaranteed returns, or claims that a particular stock will rise.
Frequently asked questions
When will the tools become available?
No release date has been fixed. The tools will be published only after they have been tested in practical research and organized into a usable format.
Will there be a free version?
The current plan is to publish a useful free sample first. A complete version may later add editable files, more detailed review fields, completed examples, and watchlist-management features.
Will the products include stock recommendations?
No. The products are intended to help users organize their own research. They will not provide personalized recommendations or tell users which securities to buy or sell.
Can the tools guarantee better investment results?
No. A checklist may reduce missed steps, but it cannot eliminate investment risk, predict future prices, or guarantee performance.
Are the tools suitable for beginners?
They are being designed for beginner-to-intermediate self-directed investors. The emphasis is on research order, practical examples, and clear distinctions between facts, hypotheses, and unknown information.
Will the products be available outside Japan?
The English versions are intended for international users. When sales begin, the purchase method, currency, file format, refund terms, and applicable taxes will be clearly stated on the product page.
What is a kessan tanshin?
A kessan tanshin is a Japanese listed company’s preliminary earnings release. It normally contains recent financial results, the company’s full-year forecast, dividend information, and other important disclosures.
Is Pine Screener itself a buy-signal system?
No. A screener only reduces the number of companies that need to be reviewed. Every candidate still requires disclosure checks, valuation analysis, liquidity review, and risk management.
