Our company started out as a silk manufacturing business in Maruko Town, Nagano Prefecture (now Ueda City) in 1951, and has been developing with the policy of "a trustworthy company, quality first, and contribution to society". In response to changes in economic development, we began to produce electrolytic capacitors and film capacitors. In the turbulent electronics industry, our TK brand continues to develop unique products that meet customer needs and gain high trust.
