Does this sound familiar?

  • We're not capturing all the billing add-ons we qualify for
  • We submit LIFE data but never actually use the feedback
  • Staff are too busy — improvements never get implemented
  • The next regulatory inspection makes us nervous
  • Documentation is consuming too much staff time
  • We want to use AI but can't make it work at the frontline
  • We're not sure our personal data handling is secure

Quick Wins — Where to Start

We clarify exactly where to begin

Three improvement axes we assess first. The free diagnosis tells you how much each applies to your facility — instantly, with no registration required.

01
💴

Capture the billing add-ons you're already entitled to — this month

Treatment improvement add-ons, LIFE, structural add-ons — it's extremely common for facilities to qualify but not bill. We work through documentation preparation and filing alongside you, converting eligibility into cash as quickly as possible.

→ Average facilities find hundreds of thousands of yen in missed monthly revenue
02
🤖

Make AI actually work at your frontline — not just installed

Installing a tool is not the same as having staff use it. We handle tool selection, implementation, and operating rule design so that care record automation, training material creation, and AI governance become part of real daily workflows.

→ Implemented facilities report 30–50% reduction in documentation time
03
📊

Get your improvement potential in numbers — free, in 5 minutes

30 questions across six domains: revenue, add-ons, LIFE, AI, cybersecurity, and regulatory inspection. Scored instantly to show which issues are highest priority and what the monthly improvement potential is. No registration required.

→ Most facilities find ¥200,000–800,000/month in improvement potential

Solution

Everything delivered in a form that actually works at the frontline

We don't explain regulations. We build systems that execute. Creating operational mechanisms that function in the real workplace is our job.

💴
Actually bill the add-ons you qualify for
From eligibility verification to documentation preparation and filing — we build the structure to ensure nothing billable goes uncaptured.
📋
Reduce documentation time
ICT and AI integration that cuts record-keeping hours without compromising quality — designed for the actual workflow, not an ideal one.
👥
Build a staffing structure that functions
Task redistribution, shift design, and productivity improvement planning — building a sustainable staffing structure that doesn't depend on overtime.
🤖
Make AI genuinely usable at the frontline
Tool selection, implementation, and operating rule design — end-to-end support until AI is a real part of daily workflows, not a shelf product.
🛡️
Prevent security and privacy incidents
Personal information governance, cyber risk response, and staff training — building the organizational defenses before an incident occurs.

Publications

30+ books — every one built from the field, not the classroom

A commercially published book is subject to public verification of its regulatory accuracy. Sustaining 30+ titles, with updated editions after every revision cycle, is evidence that the knowledge base underpinning every engagement has been tested and validated by the industry.

30+

Japan's most consistently top-ranked author in the care management category

In 2024 alone, five books updated for the FY2024 revision were published simultaneously. The series began with Japan's first book dedicated to regulatory inspection for care facilities — published at a time when preparation was entirely uncodified — and has since systematically covered eligibility requirements, BCP, LIFE, and care business operations. The accuracy of the publications is the guarantee of the consulting.

Our Difference

What sets us apart from the alternatives

This is fundamentally different from consulting that ends with an explanation. Execution support is the premise, not an optional extra.

Typical Consulting
Primarily explains the regulations. Tells you what to do and leaves.
→
Kohama / CDL
Execution support is the premise. We accompany documentation, filing, and operational embedding — not just advice.
Typical Consulting
Add-ons, AI, and security require separate specialists — coordination is the client's problem.
→
Kohama / CDL
Add-ons, LIFE, AI, and security designed and delivered as one integrated system. Integration is where the results come from.
Typical Consulting
Materials sent from outside. The real operational picture is never understood.
→
Kohama / CDL
We enter the facility. The actual problem is identified on the ground, then addressed at the root.
Typical Consulting
Specialized in one region or scale. Large multi-site or cross-regional engagements are difficult.
→
Kohama / CDL
Nationwide delivery. Experience with operators running 100+ facilities. No ceiling on scale.
Client Voices

What clients and seminar participants say

In the middle of 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.

Care Facility Manager — Kawagoe Seminar Participant

Since entering a retained consulting relationship, billing add-on leakage has dropped dramatically and we've achieved measurable revenue improvement of hundreds of thousands of yen per month. That result wasn't achievable without a specialist who genuinely knows the regulations.

Day Service Operator — Retained Consulting Client

Every "AI implementation" we'd tried before just sat unused at the frontline. Through Kohama's implementation support, we finally integrated AI into actual care record workflows. Staff overtime is visibly declining.

Special Nursing Home Director — AI Implementation Client
Industry Assessment

The assessment of Michihiro Kohama within Japan's care industry
consistently converges on one description:
"The most trusted translator between Japan's fiendishly complex care insurance system
and the operators who have to run facilities in the real world."
