Message from CEO

Message from the CEO

Invisible work, surely recorded. The shape of North and the thinking behind it.

Representative Director (CEO) Hirose Noriyuki Representative Director (CEO) / Hirose Noriyuki

Sewer infrastructure is invisible to the eye.
But if it stops, the city cannot function for even a single day.
To carry water, remove waste, and protect pipes —
our work supports daily life from places no one sees.

Work in the field, record as data.
Both, as one and the same job.

What I value as the CEO is this stance, and
being a company that stands close to every single employee.

Happiness takes a different shape for each person.
Pay, time, relationships, pride — what matters most varies by person.
That is why we value the stance of meeting each individual,
rather than imposing one answer from above.

Field × Digital × Education.
On these three axes, North is building a company where people and technique grow.
