情報の透明性
20 / 20
歯科医院についての基本的な事実、つまり在籍する歯科医師、院内の様子、診療内容、所在地が、公開情報から確認できるかどうかです。
| ✓ | 公式サイトがある [s1] | 4/4 |
| ✓ | 歯科医師名の掲載 Director Kazushi Yasumasu (furigana reading yasumasu kazushi; the clinic publishes the romanisation Kazushi Yasumasu). He is the only dentist named; the other named staff are a dental hygienist and a receptionist. [s2] | 3/3 |

料金の透明性
0 / 15
受診前に費用の見当がつくかどうかです。日本では保険診療の料金が全国一律で定められているため、料金の公開は自由診療でとくに意味を持ちます。料金の目安が公開されていれば対象となり、正確な金額の掲載までは求めません。
| ✗ | 料金表または料金の目安の公開 No price page and no figure on the home, services, information or English pages. [s1] [s3] [s4] [s5] | 0/3 |
| ✗ | クリーニング・歯石除去の料金の掲載 [s4] | 0/2 |
| ✗ | 詰め物の料金の掲載 [s4] | 0/2 |
| ✗ | 被せ物の料金の掲載 The ceramic-restoration page describes the work and a five-year free repair warranty but publishes no price. [s4] | 0/2 |
| ✗ | インプラントの料金の掲載 [s4] | 0/2 |

評判と口コミ
13 / 20
公開されている口コミの状況です。Googleの評価は、評価4.0を口コミ25件分の重みとするベイズ事前分布で補正します。数件の口コミによる5.0が、数百件の口コミによる4.8を上回らないようにするためです。
| ◐ | Googleの評価（ベイズ補正済み） Star histogram read live on 2026-09-06 from the place page: 83 five-star, 2 four-star, 2 three-star, 2 two-star, 7 one-star. The buckets sum to 96, matching the 96 in the place-page header exactly, and the weighted mean 4.583 reproduces the published 4.6. [gmp1] | 4/6 |
| ◐ | Googleの口コミ件数 Read live on 2026-09-06 from the place-page header; the star histogram sums to the same figure. [gmp1] | 1.5/3 |
| ◐ | 口コミの新しさ Newest Google review is dated 2026-06-20 (listing read 2026-09-26). [yasumasu-dental-fukuoka-gbp-2026-09-26] | 1.5/3 |
| ✓ | 口コミに返信している Owner replies to reviews on the Google listing: 1 of the 5 newest reviews answered, owner reply dated 2026-09-12 (read 2026-09-26). [yasumasu-dental-fukuoka-gbp-2026-09-26] | 2/2 |
| ✓ | 繰り返される苦情がない One critical review is readable, three months old, and it is worth quoting the substance: a tourist without Japanese health insurance says he was told before any treatment that a 27,000 yen registration fee or deposit had to be paid first. That is a single account of a charging policy rather than a repeated clinical theme. The histogram carries nine ratings of two stars or below out of 96 (9 per cent) outside the visible sample, so this false rests on the sample. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; re-checking the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 2/2 |
| ✓ | 不自然な口コミの傾向がない Histogram shape, spread of wording and dates, and reviewer-account variety show no sign of manipulation. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; re-checking the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] | 2/2 |
| ? | Facebookでの活動がある Not established: the clinic's website (12 pages read 2026-10-02) links no Facebook page and none was found under its website or Instagram name; Facebook itself could not be searched that day. | 0/1 |
| ✗ | TripAdvisorへの掲載 No TripAdvisor listing found via its search for "Yasumasu Dental Office Fukuoka" and "Yasumasu Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [yasumasu-dental-fukuoka-tripadvisor] [yasumasu-dental-fukuoka-tripadvisor-2] | 0/0.5 |
| ✗ | その他の口コミサイト No review profile on the Japanese review sites: Caloo and EPARK Dental list it only from public data, with no review, and WhatClinic has no page for it (checked 2026-10-02).

| 2026-10-05 | TripAdvisor presence checked on 2026-10-05: no listing found for this clinic. |
| 2026-10-02 | Presence re-checked: presence on other review platforms — no. |
| 2026-09-29 | Corrected 2026-09-29: active Facebook presence now unverified: no Facebook search is on record, so the absence of a page is not established; review recency within a year (newest review dated 2026-06-20); owner replies to reviews confirmed on the Google listing (owner reply dated 2026-09-12). |
| 2026-09-06 | Checked by hand in a browser: the Google Maps place page was opened in a real browser and read for rating, review count, star histogram, review recency, owner replies, complaint and manipulation reading, listing website, phone, address and pin coordinates; the checks that needed a rendering browser were worked through on the clinic's own channels. |
| 2026-09-04 | Adversarial verification pass 2026-09-04: the Kyushu Regional Bureau entry 881 (institution code 103,632,2, designated Reiwa 3.4.1 = 2021-04-01, medical corporation Iryo Hojin Yasumasu Shika Iin) and the director's register entry (Heisei 13 = 2001) reproduced live; the whole site re-read and confirmed to carry no fee page and no LocalBusiness or Dentist markup; the coordinates re-checked against the open-data record and the ward cluster. |
