"Regulations change. But the quality of your facility's documentation
can change starting today." — Michihiro Kohama
For Facilities That Have Received an Inspection Notice
A consultation is always the first step. Contact us even before you know exactly what you need.
Care records, assessments, care plans, daily logs — we verify whether each document can serve as billing evidence the way a regulatory inspector would expect. "It's written down" and "it proves eligibility" are not the same thing.
Inspectors conduct direct interviews with frontline staff — not just management. We run realistic simulation rehearsals so that the staff member who wrote the record can explain the billing basis under live questioning.
Treatment improvement add-ons, LIFE, structural add-ons — meeting the requirements is not enough. We verify that the evidence is documented and that staff can explain how eligibility is substantively fulfilled.
Why Act Now
Since the FY2024 revision, new statutory obligations and billing eligibility requirements have been added in rapid succession. Facilities that have not kept pace face an elevated risk of findings at regulatory inspection.
Under the FY2024 revision, facilities without an approved Business Continuity Plan are subject to a reduction in base reimbursement. Inspectors now require not just a written plan, but documented drill records as well.
Care service operators became required to report business and financial information to authorities. Failure to submit is a citable deficiency at designation renewal and regulatory inspection. Early preparation is essential.
Three separate treatment improvement add-ons were merged into one. Requirements for workplace environment measures, documentation, and staff explanation obligations have been tightened — and the number of inspection checkpoints has surged.
Regulatory inspections do not ask whether documents exist — they ask whether your staff can explain and prove the billing basis on the spot. In a period of continuous revision, expert on-site verification is your most effective risk hedge.
The Challenge
Reacting after findings are issued is too late. The outcome of a regulatory inspection is determined by daily accumulation — not last-minute preparation.
Inconsistencies in care records, discrepancies between assessments and care plans, missing billing rationale — these are the most frequently cited deficiency categories at regulatory inspections. "It's written down" and "it proves our eligibility" are two different things.
Simply billing for treatment improvement add-ons, LIFE, or structural add-ons is insufficient. If frontline staff cannot explain how eligibility requirements are actually being met, those billings become targets for investigation.
Even if management understands the regulations, it means nothing if the staff actually writing the records do not. Regulatory inspectors conduct direct interviews with frontline staff — not just management.
The Real Problem
Many facilities rely on self-checklist tools — but these cannot reveal the compliance gaps that matter most.
A self-check only confirms whether the facility believes it is compliant. Without an independent assessment from the same vantage point as a regulatory inspector, the real risks remain invisible.
Subtle changes in eligibility requirements and accumulated revisions are extremely difficult for frontline staff to track accurately. Incorrect practices can become entrenched before anyone notices.
Having documentation and being able to explain it on demand are entirely different capabilities. Staff must be prepared to articulate the billing rationale for their own records — under direct questioning.
The most reliable path to zero deficiency findings is
expert on-site verification and direct guidance by a specialist who knows the regulation from the inside.
Publications
There was a time when preparation for regulatory inspection was entirely uncodified — most facilities only learned the rules by being cited for violating them. Michihiro Kohama changed that by publishing Japan's first book dedicated to regulatory inspection for care facilities (Shoeisha). Since then, he has continuously systematized the knowledge frontline managers need most: eligibility requirement series (Daiichi-Hoki), BCP, LIFE, and care business operations. In 2024 alone, he published five books updated for the FY2024 revision.
🏆 Amazon Care Management Category No.1 — Multiple TitlesProfessional Network
Long-term care insurance in Japan is administered locally, with significant regional variation in interpretation. A nationwide professional network is the most powerful mechanism for maintaining regulatory accuracy at the local level.
Our Services
All services are grounded in on-site direct guidance. We don't review paper — we verify operational reality, and we coach staff to explain what they do.
An on-site visit — standard format 10:00–15:00 — during which all records, care documentation, and billing are physically reviewed and assessed against actual regulatory inspection criteria. The key difference from a self-check: we evaluate your facility from the same vantage point as the inspector. This is why the majority of retained clients achieve zero deficiency findings at their actual inspections.
| Facility Size | Estimated Duration | Base Fee |
|---|---|---|
| Up to 30 staff | 2–3 hours | ¥100,000 + travel expenses Per facility, per visit (excl. tax) |
| 30+ staff, multiple attached services, etc. | 4–5 hours | ¥150,000 + travel expenses Per facility, per visit (excl. tax) |
Kohama visits the facility to deliver a staff-facing regulatory inspection preparedness course and Q&A. The "Regulatory Inspection Simulation Service" — a 1–2 day deep-dive review of every department's care plans, daily records, financial logs, and billing — has been delivered nationwide to exceptional acclaim for over 15 years.
The critical distinction: the simulation does not merely ask whether records exist. It asks whether staff can explain the billing basis for their own records under direct inspector questioning. This depth of preparation is what drives the sustained zero-deficiency results among retained clients.
Kohama maintains retained consulting relationships with medical corporations, social welfare corporations, and for-profit care operators across Japan, conducting monthly on-site visits and staff interviews. Services extend to staff training, physician-facing long-term care insurance seminars, and structuring facility-run care manager networking sessions that build local profile.
All retained engagements are fully custom-designed. The process begins with an initial on-site meeting and senior management interviews, after which a written consulting proposal is presented for review.
The CAMP Mandatory Training SaaS Package addresses the most frequently cited inspection deficiency — incomplete training records — through a systematic platform. 20 training themes, 1,440 pages of manga-style learning content, 300 test questions, unified management for up to 100 staff. ¥45,000/year (excl. tax).

Client & Participant Voices
In the middle of highly complex discussions about billing calculation and regulatory revision, the fragmented knowledge I'd accumulated finally connected into a single coherent picture. Three hours felt like nothing.
A 113-page course text, and then an additional layer of the very latest information beyond what's written — delivered in full, every time. The only seminar where I come away with the full picture of each revision cycle.
The rigorous Kohama-method guidance dramatically reduced our risk of receiving deficiency citations at our actual inspection. Since entering a retained consulting relationship, we have consistently achieved zero deficiency findings.
The assessment of Michihiro Kohama within the long-term care industry
consistently converges on one description:
"The most trusted translator between Japan's fiendishly complex care insurance system
and the operators trying to run facilities in the real world."
