Company information
Our company was established in September 1975 as the import sales agent for BECKMAN (now BI Technology Japan Co., Ltd.), RCL-ELECTRONICS (now IRC), and CADDOCK ELECTRONICS. Since then, we have expanded our offerings to include LED products, rectifiers, relays, memory ICs from GENERAL INSTRUMENT (now VISHAY), various switches from ITW, and currently engage in the import and sales of a wide range of electronic components. Additionally, since 1977, we have also been importing mechanisms, ICs, and other electronic components for small cassettes.
