Debugging
Japan's Corporate OS
— for engineers & agencies worldwide
The hardest part of Japan isn't the language
— it's everything that isn't said.
I build the tools and frameworks to decode that gap.
Technical Strategist.
Former Automotive ECU Engineer.
A unique dual background — from the R&D lab to the classroom, now building digital infrastructure for the Japanese market.
My name is N.K. Born and raised in Japan, I spent several years working as an engineer at a major Japanese automotive OEM (JTC), specializing in ECU specification design and global technical compliance — particularly for North American market requirements (CARB/OBD).
Prior to engineering, I held official teaching licenses in Mathematics and Technical/Industrial Education. This dual background lets me do more than "explain" Japanese culture — I decompose it into logical, structured frameworks.
I witnessed a recurring pattern: brilliant international engineers struggling not because of technical skills, but because of the obfuscated codebase of Japanese corporate culture. That's what I set out to fix.
