Source Material
Every article on Pulse News Wire comes from a disclosure filed directly with TDNet. We do not aggregate from newswires, press release services, or company IR pages. The original PDF filed by the issuing company is linked in every article.
Our coverage spans the approximately 4,400 companies listed on the Tokyo Stock Exchange across the Prime, Standard, and Growth market segments.
How We Handle Numbers
All financial figures in our articles are extracted directly from the source PDF. Revenue, profit, share counts, dividend amounts, and per-share values are never generated or inferred by an AI model. Our pipeline identifies numerical data in the original Japanese document and injects it into the translation verbatim.
Narrative content, management commentary, and qualitative descriptions are translated using a large language model. That model is explicitly prohibited from producing or modifying any numerical content.
If a number appears in a Pulse News Wire article, it came from the source document. Our extraction logic is continuously refined to ensure figures are drawn from the correct reporting period. Articles published from March 13, 2026 onward reflect enhanced period-anchoring logic for earnings disclosures.
Quality Gate
Every translation is scored by our internal quality system before publication. The score evaluates structural completeness, numerical consistency, and translation coherence. Translations that fall below our threshold are withheld for review rather than published automatically.
Disclosures withheld by the quality gate are logged internally. Where the underlying document is salvageable, a corrected translation is published once it meets the threshold.
Publication Speed
Straightforward disclosures such as dividend notices, share buyback announcements, and officer changes are typically published within one to two minutes of the TDNet filing timestamp. Earnings reports and investor presentations take longer due to document complexity and quality verification, but generally publish within ten minutes.
Our crawler runs on a five-minute cycle during TSE trading hours and the pre-market filing window.
What We Cover
We cover all disclosure types filed through TDNet during Tokyo Stock Exchange trading hours and the pre-market filing window.
Duplicate Disclosures
Companies occasionally file near-identical notices through multiple channels, or a parent and subsidiary will each file separate notices about the same event. Where our system identifies a disclosure as a duplicate, it is suppressed and logged internally.
Where two disclosures cover the same event but contain meaningfully different information, such as a headline earnings flash followed by a detailed investor presentation with segment data and management commentary, both articles are published. Each links to its respective source document.
What We Are Not
Pulse News Wire is a translation and distribution service for primary source documents. We do not provide investment advice, price targets, earnings estimates, or analyst commentary. Our articles reflect the content of the original filing and nothing more.
Pulse News Wire is not affiliated with, endorsed by, or in any way connected to the Tokyo Stock Exchange, Japan Exchange Group (JPX), TDNet, or any company whose disclosures appear on this site. We are an independent translation service. The companies we cover have not reviewed, approved, or contributed to any content published here.
