COMPANY
At the centre of technologyis not technology, but people.
ATATAKAI Digital began from that one sentence.
We want to build an age in which technology connects and protects people, rather than one in which it replaces them.

NAME
A name made of warmth and the digital.
あたたかいデジタル joins the warmth that passes between people to the technology that changes how work is done. It means human-centred digital change — technology with a temperature.
Warmth
What passes between one person and another
Digital
The tools and technology that change how work is done
Warm digital
Our way of adding a temperature to technology
Not an age where technology replaces people, but one where it connects and protects them.
What we put into the name is a posture, not a feature.
MISSION
At the centre of every advance in technology, there is always a person.
ATATAKAI Digital uses technology to help people live more safely, more warmly, and for longer.
- Safety
- Technology that keeps people out of harm
- Warmth
- Technology that connects one person to another
- Endurance
- Technology that stays in use and gets handed on
Until every technology in the world has warmed up.
ATATAKAI Digital is opening the age of technology that connects people and protects them.

MESSAGE
So that people and AI can work well together.
I've spent more than twenty years where systems meet real work — from nationwide government system replacements to leading a 300-person team in Japan and Korea alongside Facebook. What stayed with me wasn't the technology itself, but the moment someone's work suddenly gets lighter.
As AI becomes ordinary, what should people hand to it, and what should stay in their own hands? I look for that answer not on paper, but in working services built together with business owners and the people on the ground.
