# Map the Japanese sources for a competitor and ask Claude to search them in Japanese

Map Japanese competitor reviews, pricing and press, then tell Claude which Japanese sources and terms to use before a native review.

Ask Claude for Japanese-language sources about the Japanese market. Anthropic’s web-search guide does not identify a search-language or region control and says Claude may use IP-derived location for localized requests. State the language and Japan scope in the request, then check whether the cited pages are Japanese. Open BOXIL, ITreview, PR TIMES and the competitor’s Japanese site yourself, record where each fact came from, and have a fluent Japanese reader check any claim before it reaches a battlecard.

This lesson assumes the competitor list exists. If you are still deciding which Japanese companies count, the [competitor identification lesson](/blog/identify-competitors) comes first.

## Separate the search locale from the output language

“Research this competitor in Japan” hides two choices: the language and region of the requested sources, and the language of the answer. A PMM at a US head office may want Japanese sources summarized in English; a PMM in Tokyo may want the same sources summarized in Japanese for the local sales team. You can explicitly instruct Claude about the answer language. For source locale, state Japanese language and Japan scope in the request, then inspect the cited pages.

Anthropic’s [web-search guide](https://support.claude.com/en/articles/10684626-enable-and-use-web-search), checked September 16, 2026, does not identify a search-language or region control and says Claude may use IP-derived location for localized requests. The [Research guide](https://support.claude.com/en/articles/11088861-use-research-on-claude) says Research uses the web and connected context. State Japanese language and Japan scope in the request, then check the cited pages.

Give Claude the competitor’s name in both scripts. Many Japanese software companies use a katakana or kanji name in Japanese and a romanized name in English, and a search on one spelling may miss pages that use the other. Then state the source language and ask Claude to report which language it used and which pages it could not open. If the cited pages are English, the result does not meet the requested source scope.

```prompt
Research [competitor, Japanese name] / [competitor, English name] for the Japanese market.
Search Japanese-language sources in Japanese. Do not translate an English query.
For each result give the URL, the page language and the source type: review platform,
press release, the company's own site, or third-party commentary.
Extract only what the page states. Keep quotations in Japanese with the URL beside them.
Finish by stating which language you searched in and which pages you could not open.
```

Summaries can be in whichever language the reader needs; the quotations stay in Japanese so a reviewer can check them.

## Where Japanese competitor information surfaces

Four places to open for a B2B software competitor in Japanese. Search snippets and Claude’s summaries point you at them; the page has to be open before anything from it is quoted.

| Source | What it holds | Basis |
| --- | --- | --- |
| [BOXIL](https://boxil.jp/) | Category listings and user reviews of business software, plus a directory of market and competitor research providers | Search results and a [third-party comparison](https://resources.nihonium.io/comparisons/boxil-vs-itreview-japan-saas), read September 14, 2026 |
| [ITreview](https://www.itreview.jp/) | Category search, user reviews, and competitor or alternative comparison pages | Same |
| [PR TIMES](https://prtimes.jp/) | Press-release distribution, where Japanese companies publish announcements such as launches | PR TIMES home page, read October 12, 2026 |
| The competitor’s Japanese site | Plan names, prices and positioning as stated to Japanese buyers, which can differ from the English site | Our recommendation: read both sites side by side |

The comparison page describes BOXIL as category-based discovery aimed at smaller companies and ITreview as closer to analyst-style grid reports. That is one content-marketing site’s framing. For this lesson we opened the BOXIL, ITreview and PR TIMES home pages on October 12, 2026. Use the table to decide where to look first, and confirm on the platforms themselves anything you will repeat.

## Use the terms Japanese buyers use

A Japanese category label is not always the translation of the English one, and a search with the wrong label returns the wrong pages. The terms below come from the platform pages and snippets we read. Keep them in a reference file so nobody re-derives them per task.

| Japanese | English | Where it comes from |
| --- | --- | --- |
| 競合調査 | competitor research | Part of BOXIL’s category name 市場・競合調査サービス |
| 比較サイト | comparison or review site | Common Japanese term for such sites; confirm on the platforms |
| 市場・競合調査サービス | market and competitor research service | BOXIL’s category name |
| プレスリリース | press release | Standard Japanese term; confirm with a native reader |
| 企業 / 会社 | company | Standard Japanese terms; confirm with a native reader |
| ソフトウェア / サービス / プラットフォーム | software / service / platform | Standard Japanese terms; confirm with a native reader |

Ask Claude to search with these terms and to flag any Japanese category name with no obvious English equivalent, so you decide whether it belongs on your map. When you collect reviews from either platform, the [review-mining lesson](/blog/review-mining) covers keeping the original passage beside your interpretation. The same rules apply in Japanese.

## Record where each Japanese fact came from

The [research plan lesson](/blog/competitive-research-plan) covers the provenance record for any market: the source, the date, and what it said. Japanese sources add three fields, because the evidence travels further from the person who can verify it: the page language, whether you read the full page or only a snippet, and who translated or reviewed the passage you rely on. Record the translator or translation reviewer so responsibility for the wording is explicit.

**Open the page before you cite it**

A finding from a page you could not open stays a lead. We could not confirm whether either review platform shows its full content without a Japanese account. A fetch result is not proof that every part of the page was available. Open the URL yourself; if you cannot, record the finding as unverified and leave it out of the battlecard.

Check each platform’s terms before copying review text into a shared document or a Claude Project. Reuse rules differ by site, and a Japanese terms page is one more thing for a fluent colleague to read. If reuse is unclear, keep the URL and your own paraphrase, marked as a paraphrase.

For repeated Japanese-market work, keep the source list, the term table and the provenance log in a [Claude Project](/blog/claude-project-setup) with your other company files. Give the competitor file an owner and a checked date.

## Add a native-review checkpoint before anything ships

A grammatically correct translation can still read wrong to a Japanese sales rep, and a category label that is fine in English can name a different category in Japan. Neither error is visible to someone reading only the English summary. The last step before a Japanese-sourced claim reaches a battlecard, brief or messaging document is a fluent Japanese reader who signs off on the specific claims.

- The competitor’s name is spelled the way Japanese buyers write it, in both scripts where both exist.
- Each cited page is in Japanese, was opened in full, and has its URL and access date recorded.
- Every quoted passage keeps its Japanese original beside the translation, with the translator or translation reviewer named.
- Category and product terms match the wording on the source pages.
- The register fits the reader: a line written for a seller’s conversation does not read like a press release.
- The reviewer signed off on each specific claim going into the brief.

This lesson did not receive native-human review. Its terminology rests on the source pages; a fluent Japanese reader has not reviewed it, and the Japanese edition carries the same note. Claude can draft the checklist; a person completes it.

## Where the manual method runs out

The manual method holds for one competitor checked occasionally. It strains when the Japan-locale instruction has to be repeated in every chat, when someone has to remember to revisit BOXIL and ITreview, and when a Japanese press release surfaces a week late because nobody searched that day.

If a Japanese competitor needs monitoring on a cadence, [Steve’s competitive-intelligence product](/products/competitive-intel) is the page to evaluate; confirm Japanese source coverage for your account. For an occasional look, the method above is enough.

## Frequently asked

### Can I set Claude to search in Japanese?

Anthropic’s web-search guide does not identify a search-language or region control and says Claude may use IP-derived location for localized requests. State Japanese language and Japan scope in your request, then check the cited pages.

### Which Japanese review sites cover B2B software?

BOXIL and ITreview. Both run category listings and user reviews in Japanese. A third-party comparison we read describes BOXIL as category-based discovery for smaller companies and ITreview as closer to analyst-style reports; treat that as one site’s framing and open the competitor’s pages on both.

### Do I need a Japanese speaker to review the research?

Yes, before any Japanese-sourced claim reaches a battlecard or brief. Claude can extract a passage correctly and still miss a register or category mismatch a Japanese seller would notice. This lesson itself did not receive native-human review.

### Does Steve cover Japanese sources automatically?

Ask Steve which Japanese sources are covered for your account before relying on it. Check any Japanese-sourced claim with a fluent reader before use.
