人気 // 人間 — A digital products studio

Quality software that respects you.

Digital products built with care. A joy to use, and honest to the core.

The name

Our name is a promise, in three characters.

Ningen — Human
You're on the other side of what we build. Every decision begins with you.
Ninki — Liked
We make things you'll want to use. If it doesn't solve a real problem, we don't ship it.
Ki — Energy
The calm you feel when software works. That's what we strive for.
What we hold to

Three rules we check everything against.

Shitsu

Quality

We'd rather make one thing great than ten things fine.

Makoto

Honest

No "fluff" or inflated promises. Our products do exactly what they say.

Hito

People

Built around you: how you think, what you need, and when you need it.

The work

Our shelf.
