“We’ve been in Japan for years. Hardly anyone knows us.”

Live in Japan, invisible to Japanese buyers

“The reports look great. Sales haven’t moved.”

Activity up, revenue flat

“HQ’s playbook worked everywhere else.”

Translated, not localized

“That part is outside our scope.”

Five vendors, four hand-offs, no owner

“Here’s the strategy. Good luck executing.”

Consulting that leaves after the deck

“Let’s spend the whole budget.”

Proposals built around budgets, not outcomes

TEAM

"With a career rooted in Germany’s leading global enterprises (SAP, BASF, Audi) and a background as a Japanese-German simultaneous interpreter, I specialize in bridging cultures through high-impact marketing and consulting. I hold a graduate degree from Heidelberg University.

My expertise lies in engineering explosive organic growth. Even for highly niche products, I design precise strategies and creatives that generate hundreds of thousands to millions of views without a dime spent on ads. On Instagram, I successfully built a following of 150,000+ in just 6 months with zero ad spend. However, my ultimate focus is never on vanity metrics; I am relentlessly committed to driving bottom-line revenue and tangible business growth.

Having backpacked across more than 40 countries, I experienced firsthand the world's profound fascination with Japanese culture. Driven by this realization, I co-founded JDOC with a clear mission: to deliver Japan’s unique value to the global stage."

"Operating at the intersection of technology and marketing, I build digital ecosystems that drive tangible revenue. During my student years, I was selected as Japan's AI & Robotics representative by the Ministry of Foreign Affairs and launched an IT service from scratch, rapidly scaling it to 20,000 monthly active users.

After exploring 30+ countries, I joined SAP Japan, where I led many large-scale IT system implementations.

My strength is cost-efficient acquisition. Because I oversee everything from data-driven ad operations and Web/App development to content marketing, I have delivered B2B leads at under ¥1,000 each and trial sign-ups for a school business at a CPA in the ¥2,000 range. I don't just "build systems"; I build engines for direct business growth.

I know both the technology and the marketing, and I use both to accelerate our clients' business. That is why I co-founded JDOC."

NAGAMINE SEICHA

“We lacked internal staff with knowledge of cross-border EC marketing and Instagram operations, so we needed outside experts. They created original posts and reels that truly resonated with our target audience.”

Tokuma Kanna

NOKID Inc.

“Preparing for a full-scale overseas expansion, we lacked resources familiar with local conditions and wanted a partner who could guide us from strategy design to execution. The specific strategies tailored to our business were very reassuring.”

Robert Heldt

CEO & Co-founder, Custom Media KK

“Whenever we require experienced professional support, particularly in video production, JDOC consistently exceeds our expectations. Their team is exceptionally friendly, responsive, and flexible, which gives us a strong sense of confidence throughout every project.”
