lecture Speaking Engagements
I started my career as a non-engineering, liberal arts professional, and jumped into the fields of AI,
XR, and IoT, learning through trial and error while working hands-on.
Based on that experience, I translate complex technologies into relatable analogies, making them easy to
understand and sometimes entertaining.
Rather than abstract, consultant-style explanations, I speak from what I've actually built with my own
hands and seen with my own eyes, which has been well-received for being high-resolution, real, and
practical.

OTHER ACTIVITIES
about About Me
I want to bring technology and people closer through creation.
I am a creative developer / engineer who focuses on XR, interactive content, and AI-powered
production.
From personal projects to commissioned development, hands-on workshops, and event speaking, I
value turning "that looks interesting" and "I want to try that" into reality.
Profile
Tatsunari Takemura
Engineer / Creator based in Hiroshima.
Started my career as a bank employee in 1993, working in various banking operations including
branch and head office roles for 30 years.
In 2017, through a secondment to Hiroshima Prefecture, I became involved in innovation
promotion, hackathon planning and operation, and IoT human resource development.
After that, I worked at a consulting company on regional revitalization projects centered on DX
and innovation.
Through side jobs and personal activities, I have a unique background of developing applications
and creating prototypes using AI, IoT, and XR in parallel with my banking career.
From February 2026, I will be working independently as a sole proprietor, focusing on
application development utilizing AI, IoT, and XR.
My strengths lie in the finance and business knowledge I gained in banking, combined with the
ability to "move my hands and quickly bring prototypes to life" that I honed through personal
activities.
