I design and build the automation and AI systems that take recurring manual work out of
small businesses — and I help operators outside Japan reach Japanese customers.
Based in Tokyo. Delivered in English across North America and Guam.
One person who knows both what sells and how to build it
Most projects lose their value in the handoff. Here there isn't one.
Marketer
Nine years running commerce and marketing operations. I know which work actually moves profit.

Engineer
I do the building myself — architecture, database, deployment, and the handover.
=
Systems that pay for themselves
No feature nobody asked for, no agency margin, no requirements lost in translation.
What I build
Four areas. Most engagements draw on two or three of them at once.
Built by one person
Scope, design, database, deployment, and handover. Nothing gets lost between vendors.
Built on what you already run
Your existing tools and accounts first. A new service only when there's no way around it.
Delivered, then adopted
I stay until the people who use it every day prefer it to the old way.
Operations automation
Spreadsheet and CSV consolidation, cleanup, and scheduled reporting
Moving data between systems that don't talk to each other
Automatic notifications by email or team chat
Jobs that run on a schedule, without anyone remembering to start them
Customer-facing chat systems
Assistants that run inside the messaging app your customers already use
Photo-in, answer-out: a customer sends an image and gets a real response
Quotes, bookings, and enquiries handled without a form or a phone call
A clean handoff to a human at the moment it matters
AI inside the workflow
Assistants that answer from your own documents and procedures
Drafting and formatting that a person only has to approve
Classifying and routing incoming enquiries automatically
AI output that feeds the next step instead of stopping at a chat window
Web systems and integrations
Internal tools built for one job and used every day
API integrations between the platforms you already pay for
Dashboards and admin screens your team can actually operate
Commerce data pulled, matched, and made visible on its own
Selling into Japan
Japan is a large, conservative, high-trust market that rarely rewards a direct
translation of what worked at home. Buyers expect a different amount of detail,
different proof, and a different way of being contacted.
Before going independent I spent four and a half years at Japan's largest
e-commerce support firm, running marketplace strategy and advertising for
more than thirty manufacturer brands. That is the part of this I can't hand to anyone else.
30+
Manufacturer brands run on Japanese marketplaces
$7M+
Annual revenue on a public-sector commerce program, at 123% of target, four years running
9 yrs
Commerce and retail operations in Japan, store floor through strategy
Marketplace entry and operations
Listing, pricing, advertising, and day-to-day operations on Japan's major
marketplaces. Including the parts that are easy to get wrong: category rules,
campaign calendars, and how product copy has to read.
Reaching Japanese visitors
If your customers are Japanese travelers, they arrive already carrying a
messaging app your local competitors don't use. I build the assistant that
answers them in Japanese, around the clock, and passes the real enquiries to you.
Localization that isn't translation
Site copy, product information, and customer communication rewritten for how
Japanese buyers decide — not run through a translator and published.
Work
Every system below was delivered and is still running. Clients are described by sector
and scale rather than by name.
Home renovation
An AI assistant that shows the customer the finished room
A customer photographs the room they want renovated and sends it through chat.
The system returns a visualization of the finished space, a ballpark price,
and a structured summary for the sales team — before anyone has driven to a site visit.
Site visit firstQualified first
E-commerce
Catching pricing mistakes before the sale goes live
Two staff checked roughly 2,000 products by eye before every promotion.
The system compares each product against what it should be and shows only the
ones that disagree.
8 hours10 minutes
Multi-site services
500 locations, collected every morning
A staff member opened each location one at a time and re-typed the day's
availability. Now it lands in a spreadsheet on its own, current all day,
with enough history to read the trend.
3–4 hours dailyNone
E-commerce
Monthly analysis that became same-day analysis
5,500 orders a month were consolidated by hand, so it could only be done once
a month. Dropping the file in now returns repeat-purchase and basket analysis
immediately. The improvement cycle runs about four times as often.
8 hours20 seconds
Manufacturing
Seven plants reporting into one sheet
Daily production records were re-typed into a spreadsheet and totalled by hand,
including yield. The output keeps the existing form layout exactly, so nothing
changed for the people on the floor.
220 hrs / yearRemoved
Construction
Quotes written from the job site, not the office
Office staff spent over an hour building each quote. Now a photo and a short note
sent from the site come back as a finished PDF, and it goes out to the customer
from the same chat window.
1 hour1 minute
Figures are measured against the process each client was running before delivery.
Rates
Quoted in US dollars. Scope sets the final number, so these are starting points rather than
a menu. These rates reflect a Tokyo cost base, not a discount — the same scope from a US
agency typically runs two to three times higher.
$30/mo
Mitsumo — my quote-and-invoice product — if that's all you need. Just ask.
JPY
Contracts are denominated in Japanese yen at the exchange rate fixed on the date of signing. USD figures here are indicative.
Focused fix
from $1,800one-time
Typical: 3–5 days
One specific piece of repeat work, scoped and removed. The usual way to start small.
Systems design and build
from $9,000per engagement
Typical: 3–4 weeks
From mapping the current process through design, build, and getting it genuinely adopted.
Fractional DX lead
from $1,800per month
Minimum 3 months
Ongoing. I identify what to change and then build it, so there's no second vendor to find.
How an engagement runs
Four stages, all handled by the same person. Time zones are worked around, not argued about —
most clients hear from me while they sleep.
Map the work
We walk through how the process runs today and find where the hours actually go. This part is free.
Design and quote
What gets automated, what stays with a person, and what it costs — decided on return, not on what's technically possible.
Build
I write it myself, from schema to deployment.
Adopt and adjust
Delivery isn't the finish line. I stay until the people who use it every day prefer it to the old way.
Whether this is a fit
I take a small number of engagements at a time, so it's worth being direct about it.
A good fit if
You want more margin out of the team you already have
The business stops working properly when you step away from it
You want commercial judgment alongside the build, not just the build
The goal is using AI, not announcing that you have it
You're going after Japanese customers and want someone who has done it
Not a fit if
Nothing about how the work is done today can change
You're expecting a system that runs the business without anyone in it
Price is the only criterion and there's no interest in the conversation
You want to hand it over and not be involved again until it's finished
About
I'm Yuta Irisawa. I run AiBou from Tokyo as an independent practice.
I came to this from the commercial side rather than from engineering. Nine years
in retail and e-commerce — store floor, then marketplace strategy and advertising
for major manufacturer brands — taught me how much of a working day disappears into
copying data between screens. It never appears in a budget, and it quietly sets the
ceiling on what a small team can do.
So I learned to build. Today I scope the problem, design the system, write it, and
stay on afterwards. Clients run in construction, manufacturing, e-commerce,
multi-site services, and professional practices.
Working in English with clients in North America and Guam is a deliberate extension
of that, not a side business — and the Japanese market knowledge comes with it.
1,700+ hrs

What's the most tedious thing your team does?
That's usually the right place to start. Tell me how the work runs today and I'll tell you
honestly whether it's worth automating — the first conversation and the process review
cost nothing, and I don't chase anyone afterwards.
