Our Story
Ishigaki Shoten was founded in 1948, starting out as a copper trading business in Nagoya. Over three generations, we moved from trading copper to fabricating it ourselves — cutting, drilling, bending and CNC-machining busbars for the transformers and switchgear inside Japan’s power systems.
Today, about 30 employees run the workshop, backed by a 70-year network of plating, welding and finishing partners in Nagoya.

Expanding into current-carrying parts for EVs and batteries — an emerging area for our copper work.
Partners since 1948
01
Direct copper sourcing, from our origins as a copper trader. We buy the material ourselves rather than through a broker, so we control quality and cost from the start.
02
Trusted plating, welding & fabrication partners in Nagoya. When a part needs a finish we don’t apply in-house, it stays local — nothing is subcontracted overseas.
03
Small lots and fast turnarounds larger suppliers can’t offer. Useful for prototypes, pre-production runs, and parts that don’t fit a mass-production line.
