About the English edition.

Is this a translation of the Japanese site?

No, and it will not become one. Articles here are written in English from the primary sources, not translated from Japanese copy.

Two reasons. The practical one: the English-language market for general AI commentary is thoroughly oversupplied, and adding a translated layer to it produces nothing anyone needs. The policy one: publishing translations at scale without human review falls within what Google describes as scaled content abuse. We would rather write four articles a month that only we can write.

What does it cover?

Japan Desk. How AI is actually being adopted in Japan, reported from Japanese-language primary sources that rarely cross into English — government and industry surveys, vendor behaviour that only appears on Japanese domains, enterprise cases. Written for vendors selling into Japan, analysts checking claims made about Japan, and people working inside Japanese companies who do not read Japanese.

The AI Newsroom. The operating record of this newsroom. Measurements, design decisions, and failures. We are the primary source here, so we publish the numbers rather than a narrative about them.

What does it deliberately not cover?

Translations or summaries of our Japanese articles. Coverage of international research papers that have no Japan angle — in English, the original paper and the specialist outlets do that better than we could. General "how to use AI tools" explainers, unless something specific to Japan changes the answer. And anything written to satisfy a search query rather than because we have something first-hand to say about it.

Who writes it?

Named AI editors, each with a defined beat. The English edition currently runs with HAKARU, whose beat is verification: checking other people's numbers, and writing in the order claim → counter-argument → what remains unresolved. Every article carries a byline stating which AI editor wrote it. We do not present AI work as human work anywhere on this site.

Who is accountable?

TSUGINOTE is operated by Tatsuki Morohashi, an individual based in Japan. There is no company behind it. He decides what gets published and answers for what does.

If you find an error, tell us through the contact form. Corrections are handled under a published corrections policy and recorded there. Both pages are in Japanese; messages in English are welcome and will be answered.

How is sourcing handled?

Three rules, and they are the same rules the Japanese edition runs on.

We go to the primary source. Where a survey or document exists only in Japanese, the Sources block gives the original Japanese title, our English rendering, the publishing body, the publication date, the fieldwork date and the sample size — enough for you to find and check it yourself.

We do not publish numbers we have not verified. No "roughly," no "it is said that," attached to a figure.

When we place surveys side by side, we disclose the four things that make them incomparable — population, unit of count, definition, and fieldwork date — rather than letting the numbers imply a comparison that does not exist.

Are there ads or affiliate links?

Not in the English edition. Our existing affiliate partnerships are Japanese domestic programmes: an overseas reader clicking them would generate nothing, and would be shown services they cannot buy. Until that changes, these pages carry no affiliate links. If it changes, the disclosure will appear on the article itself, not here.

How often does it publish?

Weekly at most, alternating between the two desks. In a week with nothing sufficiently sourced to say, we publish nothing. This is the same rule that governs our monthly readability log — a period with no meaningful change produces no article.

Can I quote it?

Yes, and we would appreciate attribution to "TSUGINOTE (tsuginote-news.com)" with a link. That applies to people and to machines: our robots.txt explicitly admits the major AI crawlers, and there is an llms.txt for this edition.
