How AI Sees Pearls.jp

We put the questions your customers actually type to four AI assistants. This is what came back. Half of it is good news.

This was a read-only review. We changed nothing on your site. Everything below is taken from recorded answers on 31 August 2026 — not estimates.

Ask where to buy pearls in Tokyo, and only one of four AI assistants says your name.
Ask in Japanese, and none of them do.
And one of them is using your own writing to recommend your competitors.

✓ Already in place

  • All four assistants know who you are and get the basics right
  • They quote your own site, not someone else's write-up
  • Technical foundation is a clean sweep — 100 / 100 / 100
  • Your English writing has depth; AI cites it directly
  • You already publish a file written for AI to read — most of the trade doesn't

✕ Not done yet

  • 137 products are absent from Google's shopping system
  • Your Business Profile doesn't cover "buying pearls" — 0 of 4 in Japanese
  • Key facts disagree: generations, review count, countries supplied
  • Nothing outside your own site confirms your history
  • 130 empty and duplicate pages are still live

→ What we'd do next

  • Settle on one version of the facts — this one costs nothing
  • Viewer access to three Google accounts
  • Decide the real market: cross-border and inbound, or domestic Japan

One customer, four assistants, four different outcomes

We used the kind of short, imperfect phrase a real person types — not a polished question.

Someone typesI want to buy pearl in Tokyo
AssistantDid it name you?Who it sent them to

Perplexity got your address, your hours and your yen prices right — so the information is there and it is findable. The other three either never found it or chose not to use it. Three customers in four walk away not knowing you exist.
Test · two

Ask in Japanese and all four miss you

Your showroom is three minutes on foot from Roppongi station. But when someone searches in Japanese, not one of the four assistants brings you up.

Someone types東京で真珠を買うならどこがおすすめですか？

All four give the same two answers: Ginza (MIKIMOTO, TASAKI, OHARA PEARL, Nichibo Pearl) and Okachimachi (PEARL SEIWA, GENERAL PEARL, Shinju Ryutsu Center).

Gemini spells the split out: Ginza = luxury brands, Okachimachi = wholesale prices.

Wholesale pricing is precisely your pitch. But your showroom is in Roppongi, and Roppongi is neither of those places.

Four assistants, zero mentions. This is not ranking poorly. This is not being on the list at all.
The counter-evidence

It is not because you lack reviews

The comfortable explanation is that you don't have enough reviews yet. We pulled the real numbers for every shop on those same lists. That explanation does not survive.

ShopGoogle ratingReviewsRecommended?
Shinju Senmonten Ryuho (Okachimachi)4.84✓ Yes
PEARL SEIWA (Ueno)4.982✓ Yes
Tokyo Pearl (Ginza)4.9140✓ Yes
Pearls.jp (Roppongi)5.0144✕ No
OHARA PEARL (Ginza)5.0256✓ Yes
MIKIMOTO (Ginza)4.3316✓ Yes
WSP (Ginza)4.9937✓ Yes

A shop with four reviews makes the list. You, with 144 reviews and a clean 5.0, do not. Even MIKIMOTO's 4.3 places ahead of you.

Your reputation is not the problem. The problem is that AI believes pearl shopping happens in Ginza and Okachimachi. Roppongi is not on that map. No amount of work on the website changes this — the levers are the categories and area signals in your Google Business Profile.

Test · three

Your own writing is working for your competitors

This is the most uncomfortable thing we found.

Perplexity, answering in JapaneseDid not recommend Pearls.jp　—　but did cite www.pearls.jp/ja/pearls-in-tokyo/ as a source

It read the Japanese buying guide you invested in, leaned on it to support its conclusions, and then published a shortlist that leaves you off.

The same Perplexity puts you first when the question is in English. In Japanese you stop being the answer and become the raw material.

Your content is good enough for an AI to cite — that is a compliment about the writing. In Japanese, that investment is bringing people to someone else's door.
Gemini, answering a shopping questionDisplayed buyable product cards

MIKIMOTO ¥572,000. TASAKI ¥1,144,000. Pearl for Life ¥181,500. Jewelry Tsutsumi ¥112,000.

Not one of them is yours. You have 137 pieces for sale and not a single one appeared.

Your competitors' product data is already inside Google's shopping system. Yours is not. The customer has reached the point of wanting to buy, and you are not on the shelf.
Test · four

Your site contradicts itself, and AI said so in front of the customer

Asked who runs Pearls.jp and how long it has been trading, all four assistants could answer. One of them got caught on your own website.

ChatGPT, word for wordAnswering "who runs Pearls.jp"

"The company's own history describes the business as having passed through three generations of pearl expertise, although Dori is the current second-generation principal." ChatGPT · recorded 31 Aug 2026

The AI did not get this wrong. It read your FAQ page, which says three generations, and your Our Story page, which says second generation, found that they disagreed, and printed both.

The About page is stranger still. On a single page it says both "Two generations" and "Three generations, from Kobe to Tokyo."

What the customer takes away: a house trading since 1969 that cannot say how many generations it has been. The other three assistants each picked one version and stated it flatly — but which one is correct is yours to decide. Until you do, which version a customer hears comes down to luck.
Claude, word for wordAfter summarising your history

"All of this comes from the company's own website … so it's their self-reported history." Claude · recorded 31 Aug 2026

Founded in 1969, JPEA member since 1971, generations of expertise — none of it is confirmed anywhere else online. You are the only source. AI discounts what it cannot verify against a second source.

In the same answer it said you supply 30+ countries. Your own materials say 40+. One more number that does not match.
Test · five

Your review count exists in three versions

We asked ChatGPT directlyWhat is Pearls.jp's Google rating and how many reviews do they have?

"Google rating: 5.0, 144 reviews. The business's own website currently says 5.0 from 145+ Google reviews, so there's a slight discrepancy between the live business listing and their website." ChatGPT · recorded 31 Aug 2026

The true figure is 144. Three numbers are in circulation right now:

Google Business Profile 144　·　your website, throughout 145+　·　the file written for AI to read 140+

An AI volunteered to a customer that your website disagrees with your own Google listing. A mismatch this small still lowers its confidence in everything else you say — and it will hand the recommendation to a competitor whose numbers line up.
What this costs you

What these things actually do to the business

Not the technical causes. Just what is already happening.

Most urgent

No coverage at all in the market closest to your door

Your showroom is walking distance for anyone already in Roppongi. But in Japanese-language searches, all four assistants leave you out. That audience is not being lost to a competitor — it was never reached in the first place.

The Japanese pages exist and the translation was done. The content is good enough that AI quotes it. The problem is not the website; it is that AI thinks pearl shopping happens in Ginza and Okachimachi.

Most urgent

Your lead in English is thinner than it looks

Ask a full, well-formed question and you come first. Change it to the short phrase a real customer types and three of four assistants drop you — ChatGPT hands the citation to OHARA PEARL's English buying guide instead.

That is not a market you have won. It is a set of phrasings you have won. OHARA PEARL is running the same playbook and closing the gap.

Most urgent

137 pieces for sale, and AI cannot sell one of them

When Gemini answers a shopping question it shows product cards the customer can buy from. Your competitors are in there. You are not — your product data has never entered Google's shopping system.

The customer has already said they want to buy. You are not on the shelf.

Most urgent

Key facts disagree, and AI repeats the disagreement out loud

Two answers for how many generations. Three numbers for your review count. Two figures for how many countries you supply. These are not internal notes — they are things AI reads back to customers.

The cost is not just one wrong sentence. AI decides whether a business is trustworthy by checking whether the same number holds up in several places. When it doesn't, confidence drops across the board.

Worth doing

The default currency on the Japanese pages

This one is not a fault. The currency switcher works, customers can move to yen themselves, and the prices are correct. It is here because changing it would noticeably improve things.

As it stands, a Japanese product page opens showing $533. A customer in Japan has to convert it in their head before they know what the necklace costs.

The effect on AI is more direct: the product data it reads is fixed in US dollars regardless of the visitor's language. Ask an assistant in Japanese what a necklace costs and the answer comes back in dollars.

Needs attention

130 blank pages are carrying your name

Among the pages you actively submit to search engines, 80 are completely empty — they open with no text at all. Another 10 are titled "REDESIGN STAGING" and are 95% identical to your homepage. Ten more are leftovers from 2020.

When a search engine sees a site carrying this many empty and duplicate pages, it marks the whole site down — including the pages you wrote well.

Minor

Loose ends in the translations

English buttons are still sitting on the Japanese, Chinese and Hebrew pages, and Japanese characters have slipped into the Chinese homepage. Not damaging, but for a house of this age it is the kind of roughness a customer notices in the first few seconds.

What is already working

None of this needs changing, and everything that follows should be built on top of it.

  • All four assistants know who you are, and get it broadly right. Ask about Pearls.jp and they return your address, your hours, the tax-free rules, 1969, JPEA membership — and they knew about the November 2026 switch to airport refunds. Plenty of your competitors cannot manage that.
  • They are quoting your own site, not someone else's write-up. That means you hold real control over how you are described. The trouble is that the control is currently being used to publish two versions of the same fact.
  • The technical foundation is a clean sweep. Measured with Google's own tooling: 100 for SEO, 100 for best practices, 100 for AI readability.
  • The English writing has real depth. The pricing guide, the quality grading, the Tokyo buying guide — AI cites all of them. That is the actual reason you come first in English.
  • You leave the door open to AI. A lot of sites block AI crawlers outright, which is a decision to sit this out. You didn't, and you went further: you already publish a file written specifically for AI to read. Most of the trade has nothing like it.
Next

Three things we would do first

About this review　Everything here comes from testing on 31 August 2026: a read-only inspection of www.pearls.jp, and questions put to ChatGPT, Claude, Perplexity and Gemini while signed in. We made no changes to your site. Fifteen full transcripts are on file.

One concern we ruled out　We had expected to find your managing director's name recorded incorrectly in Japanese-language business directories — one directory does carry the wrong name. In testing, this turned out not to matter: asked about the company in Japanese, all four assistants cited your own site and gave the name correctly. The bad entry exists, but nothing is picking it up.

现状诊断2026年8月31日www.pearls.jp

同一个客人，四个 AI，四种命运

我们用一句最普通的话去问——就是真人会打出来的那种短句，不是完整工整的问句。

有人这样问I want to buy pearl in Tokyo
AI有没有提到你们它推荐了谁
Perplexity✓ 单列一节，排第一你们，然后才是 OHARA PEARL
Gemini△ 引用了你的网站，但没推荐你银座、御徒町、百货店
ChatGPT✕ 完全没提MIKIMOTO、TASAKI、OHARA PEARL 等
Claude✕ 完全没提MIKIMOTO、TASAKI、OHARA PEARL 等
Perplexity 把地址、营业时间、日元价格全讲对了，说明信息本身是齐的。但同样的信息，另外三家要么没找到，要么找到了不用。四个客人里有三个，根本不会知道你们的存在。
实测 · 二

用日语问，四个全军覆没

展厅在六本木，日本客人走三分钟就到。但他们用日语找珍珠店时，四个 AI 没有一个提到你们。

有人这样问東京で真珠を買うならどこがおすすめですか？

四个 AI 的答案一致：银座（MIKIMOTO、TASAKI、OHARA PEARL、日貿真珠）和御徒町（PEARL SEIWA、GENERAL PEARL、真珠流通センター）。

Gemini 甚至把市场明确分成两条路——银座＝高端品牌、御徒町＝批发价。

你们主打的正是批发价。但因为店在六本木，你们不属于这两条路里的任何一条。

四个 AI，零次提及。这不是排名靠后，是不在候选名单里。
关键反证

不是因为你们评价不够

最容易的解释是「评价太少所以排不上」。我们查了同一份名单上每家店的真实评价数——这个解释站不住。

店铺Google 评分评价数AI 推荐了吗
真珠専門店リュウホウ（御徒町）4.84 条✓ 推荐了
PEARL SEIWA（上野）4.982✓ 推荐了
Tokyo Pearl（银座）4.9140✓ 推荐了
Pearls.jp（六本木）5.0144✕ 没有
OHARA PEARL（银座）5.0256✓ 推荐了
MIKIMOTO（银座）4.3316✓ 推荐了
WSP（银座）4.9937✓ 推荐了

一家只有 4 条评价的店进得去，你们144 条、5.0 分进不去。连 MIKIMOTO 的 4.3 分都排在你们前面。

问题不在你们的口碑，在于 AI 认为「买珍珠」这件事发生在银座和御徒町。六本木不在这张地图上。这一点改网站解决不了，需要动的是 Google 商家资料里的类目和地区信号。

实测 · 三

你的内容，正在替竞争对手说话

这一条是本次检查里最刺眼的发现。

Perplexity 回答日语提问时没有推荐 Pearls.jp　—　却引用了 www.pearls.jp/ja/pearls-in-tokyo/ 作为资料来源

它读了你们花力气写的日文购珠指南，用其中的内容支撑自己的结论，然后列出了一份不包含你们的推荐名单。

同一个 Perplexity，在英文提问时把你们排在第一位。换成日语，你们从「答案」变成了「素材」。

你们的内容质量已经够格被 AI 采信——这说明写得好。但在日语世界里，这份投入正在为别人带客。
Gemini 回答购物提问时直接展示可购买的商品卡片

MIKIMOTO ¥572,000、TASAKI ¥1,144,000、Pearl for Life ¥181,500、Jewelry Tsutsumi ¥112,000……

没有一件是你们的商品。你们在售的 137 款商品，一款都没出现。

竞争对手的商品数据已经进了 Google 的购物系统，你们的还没有。客人在 AI 里看到的可购买商品列表，从头到尾没有 Pearls.jp。
实测 · 四

网站在自我矛盾，AI 当场说了出来

问四个 AI「Pearls.jp 是谁在经营、开了多久」，四个都答得上来。但其中一个，被你们的网站难住了。

ChatGPT 的原话回答「谁在经营 Pearls.jp」时

「公司自己的历史页面说这门生意传承了三代，尽管 Dori 是现任的第二代负责人。」 ChatGPT · 2026-08-31 实测原文翻译

这不是 AI 弄错了。是它读了你们的 FAQ 页（写三代）和 Our Story 页（写二代），发现对不上，只好把两种说法都写出来。

About 页更特别：同一页里既写了「Two generations」，又写了「Three generations, from Kobe to Tokyo」。

客人看到的是：一家 1969 年的老店，连自己传了几代都说不清。另外三个 AI 这次各自挑了一种说法讲出去，没有说明还有另一种——但哪个才是对的，只有贵司能定。在定下来之前，客人听到哪一版全看运气。
Claude 的原话介绍完贵司历史之后

「以上全部来自该公司自己的网站，所以这是他们的自述历史。」 Claude · 2026-08-31 实测原文翻译

1969 年创业、JPEA 会员资格、三代传承——这些关键事实在网上找不到第三方佐证，只有你们自己在说。AI 会因此降低对这些说法的信任权重。

同一段回答里，它说你们供货给 30 多个国家；而你们自己的资料写的是 40 多个国家。又一处对不上的数字。
实测 · 五

你们的评价数，有三个版本在外面跑

我们直接问 ChatGPTWhat is Pearls.jp's Google rating and how many reviews do they have?

「Google 评分 5.0，144 条评价。该公司自己的网站写的是 5.0 分、145+ 条，所以线上商家资料和他们的网站之间存在出入。」 ChatGPT · 2026-08-31 实测原文翻译

真实数字是 144。而目前对外的说法有三个：

Google 商家资料 144　·　你们网站上到处写 145+　·　专门写给 AI 读的那份文件写 140+

AI 主动把「你们的网站和你们自己的 Google 页面对不上」讲给了客人听。这类小出入会拉低它对你们整体的信任，宁可去推荐一家信息干净的同行。
正在发生的损失

这些问题实际造成什么后果

不讲技术原因，只讲已经在发生的结果。

最严重

离你们最近的市场，覆盖率为零

展厅在六本木，日本本地客人步行可达。但四个 AI 在日语查询里全部没有提到你们——这部分客源目前等于零，而且不是被抢走的，是从来没进过战场。

日文页面是有的，翻译也做了，内容甚至好到被 AI 当资料引用。问题不在网站，在于 AI 认为「买珍珠」发生在银座和御徒町。

最严重

英语市场的优势比想象中脆弱

用完整工整的问句问，你们排第一。但换成客人真实会打的短句，四个 AI 里三个不提你们，ChatGPT 还把引用给了 OHARA PEARL 的英文攻略。

这不是「已经赢了」，是在一部分问法上赢了。而 OHARA PEARL 正在用同样的打法追上来。

最严重

137 款商品，AI 一款也卖不出去

Gemini 回答购物问题时直接展示可下单的商品卡。竞争对手的商品在里面，你们的一款都没有——商品数据没有进入 Google 的购物系统。

客人已经问到「想买」这一步了，你们却不在货架上。

最严重

关键事实互相打架，AI 会当众说出来

「第几代」有两种说法、评价数有三个版本、供货国家数有两个数字。这些不是内部资料，是 AI 当着客人的面复述出来的东西。

后果不只是这一条被讲错——AI 判断一家店可不可信，靠的是「同一个数字能不能在多处对上」。对不上，它就整体降低信任。

可优化

日文页面的默认币种，改一下会更顺

这一条不是错误。货币切换器工作正常，客人可以自己切换到日元，标价本身也没有问题。列在这里，是因为改动之后体验会明显更好。

目前打开日文商品页，价格默认显示 $533。日本客人要自己心算一次，才知道这条项链大概多少钱。

AI 那边影响更直接一些：它读取的商品数据里币种固定为美元，不随访客语言变化。所以有人用日语问 AI「这条项链多少钱」，拿到的仍是美元报价。

需要处理

130 个空白页正顶着你们的名字

主动提交给搜索引擎的页面里，有 80 个完全空白——打开一个字都没有。另有 10 个标题写着「REDESIGN STAGING」的测试页，内容和首页 95% 相同；还有 10 个 2020 年遗留的旧页面。

搜索引擎看到大批空白页和重复页，会下调对整站的评价，连带影响那些写得很好的页面。

小问题

翻译收尾没做完

日文、中文、希伯来文页面上还留着没翻译的英文按钮，中文首页混进了日文假名。不致命，但对一家五十多年的老店来说，是客人第一眼就会注意到的粗糙感。

已经做对的部分

这些不用改，而且后面所有工作都要建立在它们之上。

  • 四个 AI 都认得你们，而且讲得基本正确。问「Pearls.jp 是谁」，地址、营业时间、免税规则、1969 年创业、JPEA 会员，四家全答对了，还讲出了 2026 年 11 月免税改机场退税的新政策。这一步很多同行做不到。
  • 它们引用的是你们自己的网站。不是转述第三方媒体——这意味着你们对自己被怎么描述，握有实际的控制权。问题是这份控制权目前在输出矛盾的内容。
  • 技术底子是满分。Google 官方工具实测：SEO 100 分、最佳实践 100 分、AI 可读性 100 分。
  • 英文内容深度足够。价格指南、品质分级、东京购珠攻略，AI 都在引用——这是你们在英文里能排第一的真正原因。
  • 你们对 AI 是开放的。不少网站把 AI 挡在门外，那等于主动退出这场竞争。你们没有犯这个错，还专门准备了一份写给 AI 读的公司说明文件——业内绝大多数商家还没有。
下一步

我们建议先做的三件事

关于这份报告　所有结论来自 2026 年 8 月 31 日的实测：对 www.pearls.jp 的只读检查，以及对 ChatGPT、Claude、Perplexity、Gemini 四个 AI 的登录状态提问。我们没有对贵司网站做任何修改。共 15 份完整问答记录存档备查。

已排除的一个说法　我们曾担心日语世界里贵司负责人姓名被第三方企业名录写错（该名录确实写错了）。登录状态实测下未发现这个问题——用日语问公司名，四个 AI 引用的都是贵司官网，负责人姓名正确。该风险存在但目前没有生效。
