The reading

Dozens of sources, one brief.

Most of what Tokyo publishes appears only in Japanese, across dozens of ministry and exchange websites. We read the filings, notices, and statistical releases each day and write up what moved. You get the stories, not the search.

The record

Every story links to its document.

Each article cites the filing, release, or notice it was drawn from. Figures stay attached to their reporting periods. Claims are fact-checked against the source before publication. Check any figure against the original yourself.

The cadence

Sent after Japan closes.

One issue each weekday, sent in the Tokyo evening once the exchange has closed and the filings are in. That is mid-morning in London and early morning in New York.

Who reads it

For readers whose work depends on Japan.

Read by people who allocate capital, set strategy, advise, or report on Japan.

Investors and analysts
The filing, read before the call.
Executives and strategists
The policy line before the board asks.
Advisers and consultants
The ministry budget item, with its context.
Journalists and the Japan-curious
The document, not the summary.

What we read

40+ official sources, read every day.

No wire copy, no aggregators. Every story starts with a document a Japanese institution published, usually in Japanese, often to little notice outside Japan.

Exchange and securities filings
Every securities filing and timely disclosure from Tokyo's listed companies, as filed.
Ministries and the central bank
The Ministry of Finance, the Bank of Japan, METI, and the ministries behind the day's policy.
Regulators and enforcement
The FSA and the enforcement bodies whose decisions move sectors and single names.
Statistics and public notices
Trade, immigration, tourism, energy, and public-finance releases, plus the notices few read.
