General Anaesthesia & Deep Sedation
Whether the clinic documents treatment under general anaesthesia or deep / twilight sedation — "sleep dentistry", where the patient is asleep and unaware (does not feel, see, or hear the procedure). Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.

20 / 20
Whether basic facts about the clinic - its team, premises, services, and location - are publicly verifiable.
| ✓ | Has a working website [s1] | 4/4 |
| ✓ | Dentist names listed Four dentists named on the clinic's own staff page: 中居 伸行 (director), 城下 隆一 (deputy director), 赤坂 衣理, 柳 珍郁. Names are reproduced as the clinic publishes them, in kanji; the clinic publishes no romanization for its dentists. [s2] | 3/3 |

| ✓ | Service list published [s1] | 3/3 |
| ✓ | Clear contact details Phone, address, opening hours and an enquiry form on the clinic's own site; the phone matches the Kinki Regional Bureau register entry. [s1] | 2/2 |
| ✓ | English website version English treatment-information section on the clinic's own site (not a full mirror of the Japanese site). [s5] | 2/2 |
| ✓ | Address and map published [s1] | 2/2 |
Price Transparency
9 / 15
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✓ | Prices or price ranges published Standing self-pay fee table (料金表) covering crowns, inlays, implants, dentures, whitening and aligners; not a time-limited offer. [s3] | 3/3 |
| ✗ | Cleaning price listed The fee table carries no cleaning/scaling figure; cleaning is billed under national health insurance. [s3] | 0/2 |
| ✗ | Filling price listed No filling figure in the fee table (insured treatment). [s3] | 0/2 |

Reputation & Reviews
14 / 20
Public review signals. The Google rating is adjusted with a Bayesian prior (rating 4.0, weight 25) so a 5.0 from a handful of reviews does not outrank a 4.8 from hundreds.
| ◐ | Google rating (Bayesian-adjusted) Star histogram read live on 2026-09-06 from the place page: 94 five-star, 9 four-star, 1 three-star, 4 two-star, 16 one-star. The buckets sum to 124, matching the 124 in the place-page header exactly, and the weighted mean 4.298 reproduces the published 4.3. [gmp1] | 3/6 |
| ◐ | Google review volume Read live on 2026-09-06 from the place-page header; the star histogram sums to the same figure. [gmp1] | 2/3 |
| ✓ | Review recency The newest review visible is 3 months old, which proves the within-3-months bucket and no better. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. The Newest sort does not open to the extension (re-tested on this run by opening the Reviews tab and scrolling the panel, which returned the same three reviews), so no fresher slice is available. [gmp1] | 3/3 |
| ✓ | Clinic responds to reviews The owner replied to all three reviews Google renders, including the one-star one. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. The Newest sort does not open to the extension (re-tested on this run by opening the Reviews tab and scrolling the panel, which returned the same three reviews), so no fresher slice is available. [gmp1] | 2/2 |
| ✓ | No recurring complaints One critical review is readable, three months old: a long-standing patient says the counter staff are disrespectful and describes being challenged over arriving three minutes late. One grievance is not a repeated theme, and the owner answered it. The histogram carries twenty ratings of two stars or below out of 124 (16 per cent) that the sample cannot reach, so this false rests on the sample. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. The Newest sort does not open to the extension (re-tested on this run by opening the Reviews tab and scrolling the panel, which returned the same three reviews), so no fresher slice is available. [gmp1] | 2/2 |
| ✓ | No suspicious review patterns 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. The Newest sort does not open to the extension (re-tested on this run by opening the Reviews tab and scrolling the panel, which returned the same three reviews), so no fresher slice is available. [gmp1] | 2/2 |
| ✗ | Active Facebook presence The clinic's site links Instagram (@nakaidental) but no Facebook page. [s1] | 0/1 |
| ? | TripAdvisor presence | 0/0.5 |
| ? | Other review platforms | 0/0.5 |
Medical Infrastructure
15 / 15

| ✓ | Orthodontics Invisalign Go and ClearCorrect aligner treatment, priced in the fee table. [s3] | 2/2 |

| ✓ | Works with international patients English-language page states the clinic has treated many English-speaking Kyoto residents and charges no surcharge for English support. [s5] | 2/2 |

6.5 / 10

| 2026-09-06 | Combined browser pass (agent I-3, korea + japan): 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 country worklist rows that needed a rendering browser were worked through on the clinic's own channels. |
| 2026-09-04 | Adversarial verification pass 2026-09-04: the Kinki Regional Bureau workbook re-downloaded and re-read to the last of its 1,214 rows, entry 207 (医療機関コード 03-0424-0, 指定 令4.5.1, 医療法人インターメディカル, 管理者 中居 伸行) reproduced exactly; all four dentist register entries reproduced live under both gender filters; every figure in the self-pay fee table re-read; the published romanisation corrected to the form the clinic itself uses. |
| 2026-09-04 | Initial data collection for the Japan Dental Transparency & Trust Index: verified against the clinic's own site, the Kinki Regional Bureau of Health and Welfare health-insurance institution list (snapshot 2026-09-01) and the MHLW national dentist register. |
