We started our enterprise as SAN-EI Kagaku Kenkyusho (Laboratory) in 1950.

We developed the first hair cosmetic in Japan “EMACOL”, and manufactured and sold it in
the domestic market. Based on the technologies cultivated in this field, we entered into the
electronics industry. Since then our technologies and reliability have been appreciated by
the customers for more than 45 years.

  We will continually keep our efforts to establish a firm and an unique technology to 

contribute to the electronics industry which will be innovating day by day.
