Connecting Japan's manufacturing to the world.
Through the procurement of electronic components and PCBs, we support Japanese manufacturing excellence. Guided by Japanese values and culture, we stand at the heart of the global supply chain.
Supporting Japanese manufacturing
through the power of procurement.
The electronics industry is the backbone of Japan's economy. Sourcing high-quality components at the right cost and with supply stability is the foundation of product competitiveness. Leveraging our direct partnership with Guangdong Chengde Electronic Technology, Denro Keikaku helps Japanese companies compete and win in the global market.
Building Resilient Supply Chains
In a global environment where component shortages have become the norm, our direct partnership with Guangdong Chengde Electronic Technology and multi-source strategies deliver stable supply. We ensure production lines keep running.
Direct Sourcing Without Middlemen
Our direct partnership eliminates intermediary margins, optimizing cost without compromising quality. The savings flow directly into your R&D investments and talent development.
Elevating Industry-Wide Procurement Literacy
Our 101-article PCBiroha knowledge hub is freely available to all — raising the procurement knowledge base across Japan's entire electronics industry beyond individual company gains.
No matter where we source from around the world,
what we deliver is Japanese trust.
Quality. Sincerity. Integrity. — These are our procurement standards.
— Denro Keikaku Philosophy / 電路計画の信条
Culture is the etiquette of business.
At the root of Japanese business practice lies a culture refined over centuries. It is not merely etiquette — it is a philosophy for building trust. Denro Keikaku embodies this culture in every transaction with global partners.
Ma — The Art of Space
Never rush, never impose. We respect our clients' pace and space, offering support at the right moment in the right form.
Takumi — Artisan Pride
Mastery lives in the details. Every specification line, every negotiation point — approached with the spirit of a craftsman, no compromises.
En — The Value of Connection
Business begins with encounter. We cherish every relationship not as a transaction, but as a long-term bond to grow together.
Makoto — Sincere Commerce
Good news and bad alike, we communicate openly and honestly. That transparency is the foundation of Japan's merchant tradition.
Wa — Harmony Above All
We pursue transactions where every stakeholder finds sustainable value. Mutual benefit is the strongest supply chain.
Kaizen — Continuous Improvement
Better today than yesterday, better tomorrow than today. We continuously improve processes, knowledge, and service to deliver ever greater value.
Four values we hold dear.
Every action at Denro Keikaku springs from values Japan shares with the world. These are not slogans — they are a living philosophy reflected in every transaction we undertake.
Uncompromising Pursuit of Quality
We work exclusively with ISO- and IATF-certified facilities of Guangdong Chengde Electronic Technology, applying clear quality standards from prototype through mass production.
One hundred trusts over one transaction
We charge nothing until a deal is closed. We deliver value first and let trust accumulate. Long-term partnership follows naturally — that is how we build business that lasts.
Our responsibility to close the information gap
Our 101-article PCBiroha knowledge hub is the embodiment of our belief — democratizing knowledge to strengthen Japan's manufacturing competitiveness.
Keeping promises is the greatest differentiator
Do what you say. Decline what you cannot deliver. Face problems with accountability. We carry this integrity into every global procurement engagement.
