About Us
Connecting business and delivery, building products hands-on.
Rojiura Studio is a product studio led by Yusuke Namai. We combine hands-on product management with AI-assisted development, supporting ideas through MVP delivery, launch, and ongoing improvement.
About us
Our founder has worked on hardware, IoT, and digital products at Pigeon, LIXIL, Sun Asterisk, and Plugo, connecting customer research, UX, requirements, and external development partners.
We also develop our own products, including STOQ, Hatake., Ototori, and Wadachi, with experience launching and improving web and iOS apps. Working software and user feedback guide the next step.
ROJIURA STUDIO Our strengths
On-the-ground partnership
Not theory from a deck. We go deep into the real work and design systems that get used.
Workflow × AI design
Grounded in process, data, and culture — we deliver AI that drives outcomes.
Committed to adoption
Training, operating design, improvement cycles — we see it through with your team.
Business impact first
Beyond cost cuts — results that move revenue, quality, and speed.
From the founder
AI is not only for special companies.
Combined with the wisdom of the floor, it can create real change in any business.
We exist as a quiet kind of support — like a lantern in a back alley — helping shape what comes next, steadily and surely.
