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.
- ? General anaesthesia / deep sedation (sleep dentistry) — Not verified
Summary
Referral-style specialist clinic three minutes from Osaka/Umeda station, opened in 2019 and limited to periodontal and implant treatment: it declines general dentistry and refers those cases out, and it explains on its own site why it works entirely outside the national health-insurance system. Its founder, Dr. Shota Tsuji, completed the periodontics residency at Columbia University, is a Diplomate of the American Board of Periodontology and holds a Washington State dental licence alongside a teaching post at Osaka University. Only one figure is published — a JPY 55,000 first-visit package covering the examination and the consultation across two appointments — with treatment fees quoted after diagnosis.
Strengths
- Information Transparency: 20 of 20 points.

Score Breakdown
Every criterion below is scored from public sources. ✓ verified yes · ✗ verified no / not found · ◐ partial · ? unverified (scores 0, not a negative finding).
Information Transparency
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 辻 翔太 (Shota Tsuji), founder and managing dentist. [s2] | 3/3 |
| ✓ | Dentist specializations listed Columbia University periodontics residency; Diplomate, American Board of Periodontology (2018); Master of Science; US (Washington State) dental licence; visiting faculty at Osaka University Faculty of Dentistry. [s2] | 2/2 |
| ✓ | Real clinic photos [s1] | 2/2 |
| ✓ | Service list published Precision periodontal examination, non-surgical periodontal therapy, periodontal regeneration, root-coverage surgery, implants, bone augmentation, peri-implant disease treatment, periodontal maintenance, prophylaxis and orthodontics. [s1] | 3/3 |
| ✓ | Clear contact details [s4] | 2/2 |
| ✓ | English website version English landing page; the treatment pages behind it remain in Japanese. [s3] | 2/2 |
| ✓ | Address and map published [s4] | 2/2 |
Price Transparency
Whether patients can estimate costs before visiting. Published price ranges count; exact prices are not required.
| ✗ | Prices or price ranges published Only the first-visit package is priced; the clinic states that treatment fees are quoted at the second appointment after diagnosis. [s5] | 0/3 |
| ? | Cleaning price listed | 0/2 |
| ? | Filling price listed | 0/2 |
| ? | Crown price listed | 0/2 |
| ? | Implant price listed | 0/2 |
| ✓ | Consultation price listed First-visit fee JPY 55,000 including tax, covering the examination and consultation across the first two appointments with no further charge before treatment starts. [s5] | 2/2 |
| ? | X-ray / imaging price listed | 0/2 |
Reputation & Reviews
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: 10 five-star, 0 four-star, 0 three-star, 0 two-star, 4 one-star. The buckets sum to 14, matching the 14 in the place-page header exactly, and the weighted mean 3.857 reproduces the published 3.9. [gmp1] | 1/6 |
| ◐ | Google review volume Read live on 2026-09-06 from the place-page header; the star histogram sums to the same figure. [gmp1] | 0.5/3 |
| ✓ | Review recency The newest review visible is 2 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 two of the three reviews Google renders. 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 Deliberately left unknown. Four of the fourteen ratings - 29 per cent of the base - are one-star, so recording 'no recurring complaints' as false would credit a clean record the distribution contradicts; but all three reviews Google renders are five-star, so no negative is readable and no theme can be demonstrated either. 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. | 0/2 |
| ✓ | No suspicious review patterns The 10/0/0/0/4 shape is a small, sharply divided base rather than a manipulation signature. 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 |

The range of publicly documented equipment and services. This measures documented availability, not clinical quality.

| ✓ | Orthodontics Orthodontics is on the treatment menu and is the only treatment offered on Tuesdays and Sundays. [s1] [s4] | 2/2 |
| ✓ | Oral surgery Periodontal regeneration, root-coverage grafting and bone augmentation. [s1] | 2/2 |
| ✗ | Pediatric dentistry The clinic treats periodontal and implant cases only and refers all other treatment to partner clinics. [s5] | 0/1.5 |
| ✗ | Emergency care Appointment-only specialist referral practice; general and urgent care is referred out. [s5] | 0/1.5 |
| ? | Works with international patients The English page presents the clinic but does not document arrangements for international patients. | 0/2 |

Licensing & Credentials
Whether the clinic publishes its operating licence and the dentists working there together with their professional licence numbers. A verified “not published” is recorded as a red flag; data we have not checked yet is shown as unverified and carries no penalty.
Clinic operating licence: 医療機関コード 3270086930 — registered 歯科診療所, Osaka (都道府県コード 27), MHLW 医療情報ネット; founder and managing dentist 辻 翔太, facility record last updated 2026/3/9. Corroborated by the MHLW open-data release of the same register, snapshot 2025-12-01. (The clinic is absent from the 近畿厚生局 dental 保険医療機関 designation list as of 2026-09-01 (5,240 institutions read to the last row). That is consistent with its own statement that it works entirely outside the health-insurance system, and is not evidence of a missing licence.) [reg1] [reg2] [reg4]

Change History
| Date | Change |
|---|---|
| 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 近畿厚生局 Osaka dental list re-read to the last of its 5,240 rows and the clinic confirmed absent (searched by telephone, name, 開設者 and 管理者), consistent with its published self-pay-only policy; the licence search re-run under both gender filters; geo left null because the clinic's own record in the MHLW open data carries the placeholder coordinates 0.0 / 0.0 — queued for the browser pass. The English name Specialized Periodontics and Implant Dentistry Osaka is the facility's own declaration in the statutory register, not an invented romanisation. |
| 2026-09-04 | Initial data collection for the Japan Dental Transparency & Trust Index: verified against the clinic's own website, the MHLW 医療情報ネット facility register and its open-data twin, the 近畿厚生局 health-insurance designation list and the MHLW dentist qualification search. |
