Software Products Studio
Grow value, and pass it on.
Mumu Labo is a small studio building handy tools for everyday work and life. My own products — planned, built, and run by me — are the core of it, and I also take on custom development.
Name & values
What I care about
The name “Mumu” comes from elephants passing something precious trunk to trunk — parent to child to grandchild — a value that grows a little larger each time it is handed on. That image is what I want my work to be: paying value forward, and then some.
Receive up close
Like elephants greeting trunk to trunk, I get close first. I start by taking in the real problem behind the request — and the value you have already built up.
Grow the value
I don’t hand things back unchanged. I grow them into tools, researched against Japanese business practices, regulations, and language, and built to stay useful for years.
Pass it forward
The grown value goes to a user, and spreads from there to others. Feedback from the people using it feeds the next round of development and reaches new users again — value that grows as it is paid forward.

Tools that take the busywork out of everyday work — the core of what I build. Shopify first, other platforms later.
UreyukiBox
Demand forecasting & inventory planning
Demand forecasting tuned to Japanese business practices: it suggests what to reorder and how many — subtracting stock on hand and incoming POs from your reorder point — and shows the reasoning behind each number. Create qualified-invoice-ready purchase orders (registration number, tax class, transition measures) as PDF/CSV in one click, with low-stock alerts to LINE / Slack. Multi-location ready.
DenchoBox
Japan compliance automation
Built to Japan's e-bookkeeping retention rules — searchable, tamper-evident, with an edit/delete history — DenchoBox auto-archives your Shopify order documents. It also issues qualified invoices as PDFs and audits your commercial-law, premiums-labeling, and stealth-marketing disclosures — the compliance work Japanese businesses need, in one place. Shopify first.
Palette Studio
Pharma-law-safe AI content
A pharma-law-safe AI content suite for D2C brands in Japan — full-catalog compliance scanning plus product copy, ad copy, and AI product photography. (Awaiting v2 resubmission.)
