PROBLEM 01Work is person-dependent
Only one person knows the steps; work stops on leave, resignation or transfer.
AI adoption that starts by taking on your work
You want to use AI. But where do you start? First, we take on the work.
You don't need to know what to delegate yet. We take on your back-office work, make it visible, and adopt AI in at least one business process within six months.
Your first consultation is free. You don't need to have decided what to delegate.

YOUR CHALLENGES
Before AI, is thework itself visible?
When work depends on individuals and is scattered across paper, Excel, email and verbal checks, dropping an AI tool on top has limited effect.
PROBLEM 02The work isn't visible
You can't see how long each task takes or where the waste is.
PROBLEM 03Scattered across paper, Excel & email
Information is spread across places, causing rechecks, transcription and double entry.
PROBLEM 04Not ready for AI yet
With vague workflows and rules, you can't decide what to automate.
That's why NaruTech doesn't start with AI. We start by taking on the work and making it visible.
6-MONTH ROADMAP
In six months, we adopt AI inat least one business process.
The first three months are for getting used to the work; the next three are for running improvements. That is how we reach AI adoption in six months.
Take on the work & get used to it
- Decide the target work and take it on
- Grasp steps, stakeholders & criteria
- Create work records & workflows
- Get used to the work until we can run it
Run improvements & adopt AI
- Find waste, duplication & person-dependence
- Draft improvements and run them
- Build manuals & systems
- Adopt AI in one business process
Embed & expand
- Embed the AI-adopted work in operations
- Keep manuals & workflows up to date
- Expand the scope of AI use
- Roll out to other work & teams
From month 7, the Continuous Improvement plan keeps the 2-day/week on-site to embed and expand
WHAT WE DO
Take on the work, make itvisible, and adopt AI.
01 TAKE ON THE WORK
First, we takeon the work.
Our AI engineers take on part of the work, learning like an apprentice. Rather than just observing, we do the work ourselves to understand what really happens in the field.
Handover & partial delegation

02 MAKE IT VISIBLE
We list the workand map it into a flow.
We organize daily tasks, decision criteria, exceptions, the tools used and the checks, and put them into a workflow and draft manual. Person-dependent work becomes something anyone can follow.

03 IMPROVE & ADOPT AI
We run improvements andshift to a flow that runs with AI.
Building on the current flow, we decide what to cut, what to standardize, and which steps AI takes on — then run it. Rather than relying on AI alone, we keep human-review steps so the improvement lasts.

WHY NARUTECH
Why teams chooseAI Promotion Office.
More than outsourcing
Rather than just running fixed tasks, we dig into the work and carry visibility, improvement and AI adoption through as one.
On-site 1–2 days a week
Our AI engineer runs the work in person, spotting waste, person-dependence and improvements on the ground.
The system stays in-house
We build workflow diagrams, manuals and an AI-driven process, so you don't stay dependent on an outside vendor.
PRICE
An initial 6-month plan, pluscontinuous support from month 7.
In the first six months we take the work through to AI adoption in one business process; from month 7, the continuous plan supports embedding and expansion.

SCOPE
What we canand can't do.
This service combines existing generative AI and GAS to get one business process running automatically. Full-scale system development or adoption from scratch is out of scope.
What we can do
Automate one process with existing tools × generative AI
- Custom prompt design for generative AI (drafting invoices & notices, summarizing, classifying, etc.)
- Automating routine work with GAS (Google Apps Script): transcription, aggregation, notifications, spreadsheet integration
- Combining existing tools such as Google Workspace, Forms and Spreadsheets
- Leaving the know-how behind as business flow diagrams, procedure manuals and checklists
- Getting one business process running while keeping a human-review step
Out of scope (full-scale system adoption)
Newly developing or adopting a dedicated system
- Developing or adopting dedicated business systems such as CRM or SFA
- Scratch development of custom databases, web apps or core systems
- Large-scale system integration or building API platforms
- Company-wide overhaul of business systems
*If you need these, they can be discussed as a separate NaruTech service, such as system development or DX support.
Here, "full-scale" means newly developing or adopting a dedicated system. This service combines the tools you already have (generative AI, GAS, Google Workspace, etc.) to get your current work running automatically — in the shortest time and at the lowest cost.
OUR COMMITMENT
Before we start, there area few premises we share.
The key numbers are shown at the top of the page. Here we summarize the premises — contract type and conditions — to confirm before we start.
What we tell you upfront
Our AI engineers are often new to your industry and its specific work, and cannot handle everything smoothly from the first month. The plan is designed so they get used to the work in the first three months, then drive improvement and AI adoption in the next three.
It's a quasi-mandate
As this is not worker dispatch, you cannot directly command our on-site members. Work requests and priority changes are coordinated through our PM or designated contact.
In principle, within Akita
For visits or on-site work outside Akita, travel, lodging and per-diem are billed at cost. Online support can also be combined — just ask.
1 or 2 days per week
Light is 1 day/week and Standard is 2 days/week as a baseline. Days and working style are decided together before we start.
FAQ
Frequently asked questions
QDoes the service start with AI adoption?
A
No. We start by taking on the work, understanding it, and making it visible. AI adoption happens once we understand the operation and the direction of improvement is set.
QCan you also build a system like CRM or SFA?
A
No. This service combines existing generative AI (custom prompts) and GAS (Google Apps Script) to get one business process running automatically. Newly developing or adopting dedicated systems such as CRM or SFA is out of scope. If you need such a full-scale system, it can be discussed as a separate NaruTech service, such as system development or DX support.
QCan we start with just one process?
A
Yes. Accounting & billing, general affairs, sales admin, recruiting and more — you can start with one process, see the effect, then expand the scope.
QCan we engage even without internal manuals?
A
Yes. We organize the steps and decision criteria while doing the actual work. Creating the manuals is itself part of the support.
QHow often is the engineer on-site?
A
As a baseline, the AI engineer is on-site 1 day/week on the Light plan and 2 days/week on the Standard plan. Depending on the work, online support and different schedules can be discussed.
QCan we directly command the on-site members?
A
As this is not worker dispatch, direct command isn't possible. Work requests and priority changes are coordinated through our PM or designated contact.
QCan we continue after six months?
A
Yes. With the Continuous Improvement plan, the 2-day/week on-site continues while we embed the AI-adopted work, roll it out to other tasks, and update manuals. To expand across departments, we propose the Custom plan.
Tell us the workyou'd like to improve.
You don't have to start by dropping in an AI tool. Tell us about the work that's causing trouble or the work that depends on one person. NaruTech takes on the work and adopts AI in at least one business process within six months.
