Japanese Coffee Gear

Last updated: June 2026

Editorial Policy

Japanese Coffee Gear translates and documents Japanese coffee culture for English readers — the drippers, the brewing methods, the roasters, and the farms. This page explains where our information comes from, how we verify it, and the role of artificial intelligence in our workflow.

Our Mission

Most of the best writing about Japanese pour-over exists only in Japanese: Hario's engineering notes, Standart Japan, Tetsu Kasuya's recipe explanations, kissaten manuals, and producer websites in Okinawa and Ogasawara. We read those sources, translate them faithfully, and always link back to the original. If a claim in one of our articles matters, you should be able to follow it to its Japanese source.

Translation & Source Attribution

  • Every translated claim is cited. Articles drawing on Japanese-language sources link to the original page, named and in context — never uncredited paraphrase.
  • We preserve meaning over literalism. Where a Japanese term has no clean English equivalent (e.g. 蒸らし / blooming), we keep the original term and explain it.
  • We do not invent quotes or specifications. Brew specs, founding dates, and product dimensions come from manufacturer pages or primary reporting, not memory.

The Origins Dataset

Our Origins dataset — Japan-grown coffee farms and the country's leading specialty roasters — is compiled from named, public sources: the Japan Times, Sprudge, Perfect Daily Grind, Typica, producer and roaster websites, and regional reporting. Every record carries its own source citations, and the dataset page lists the full source roster. It is published under a CC-BY-4.0 license so anyone can verify, reuse, or correct it. We re-review the dataset on a stated refresh schedule and version it; we would rather list 16 verified farms than 60 rumored ones.

Gear Reviews & Recommendations

  • We recommend gear based on published specifications, documented brewing results, and aggregated owner experience — and we say which is which.
  • We report drawbacks (fragility, filter availability, price drift) alongside strengths.
  • A manufacturer cannot pay for a better writeup. See independence below.

AI-Assisted Research Process

We use artificial intelligence tools (including large language models such as Claude by Anthropic) as part of our workflow. Here is how AI fits in and where human judgment takes over:

What AI Does

  • Research and translation support: AI helps locate relevant Japanese-language sources and produce first-pass translations.
  • Draft generation: AI produces initial drafts from source material, which serve as a starting point for editing.
  • Consistency checks: AI cross-references brew specs, dates, and names against the cited sources and flags inconsistencies.

What Humans Do

  • Editorial review: Every article is reviewed by a human editor for accuracy and clarity before publication.
  • Source verification: Editors verify that cited sources exist, are accurately represented, and are linked.
  • Editorial judgment: What to cover, how to frame it, and what to recommend are human decisions.
  • Final approval: No content is published without human sign-off.

Corrections Policy

  • Minor corrections (typos, formatting, non-material clarifications) are made directly without a notice.
  • Material corrections (factual errors, mistranslated claims, wrong specifications, dataset errors) get a visible correction notice stating what changed and when.
  • Dataset corrections: Errors in the Origins dataset are fixed in place and noted in the dataset's version history.

To report an error, email editorial@japanesecoffeegear.com with the URL and a description of the issue. We respond within five business days.

Independence from Advertisers

  • Affiliate partners and advertisers have no input into our editorial content, ratings, or recommendations.
  • We do not accept payment in exchange for favorable coverage.
  • Our editorial team is not compensated based on affiliate revenue or advertising performance.
  • We cover gear, roasters, and farms with which we have no commercial relationship whenever they are relevant to readers. If a conflict of interest exists, we disclose it in the article.

See our affiliate disclosure for how the site makes money.

Content Updates

Gear availability, pricing, and roaster lineups change. We periodically re-review published content, and articles display a "last updated" date. Key update triggers: discontinued or revised products, new primary reporting on farms or roasters, recipe revisions from the original authors, and reader corrections.
