Junkosha Inc.

Junkosha is a pioneer of sophisticated fluoropolymer application technologies across a broad selection of industries, including the microwave interconnect sectors. 

Our mantra – indeed the name Junkosha – is based on three Japanese characters that spell out the fact “we contribute to society’s development through technology”.
