We would like to express our sincere gratitude for your continued support.

Kohoku Kogyo (“the Company”) was founded in 1959 to manufacture lead terminals for aluminum electrolytic capacitors. Since then, we have pursued craftsmanship for over 60 years.

Lead terminals are key parts of aluminum electrolytic capacitors, which are crucial components used in a wide range of electronic products including automobiles, industrial equipment, IT equipment and consumer products. Performance and reliability of capacitors rely on lead terminals. Over many years, the Company has made steady and earnest efforts in R&D to enhance the performance of lead terminals and development of manufacturing technologies to enhance production efficiency and quality. Currently, we secure a 95% market share for for-vehicle aluminum electrolytic capacitors, which are exposed to the harshest operating environments.

Moreover, we have been expanding our business into optical communication areas since 2000, taking advantage of the precision processing technologies we have accumulated in the lead terminals business. For optical isolators, our mainstay product, we have a market share of over 50% in the market for submarine optical cables, which are required to operate stably for 25 years in a harsh environment on the seabed at a depth of 8,000 meters with 800 atmospheres. In addition, we are promoting entry into new, cutting-edge niche areas by applying and developing the know-how we have fostered over many years.

On December 21, 2021, the Company was successfully listed on the Tokyo Stock Exchange (TSE) Second Section, and now belongs to the TSE Standard Market. Expressing our heartfelt gratitude for your support and encouragement, we will continue to develop even higher value-added products under our corporate philosophy of “aim to become a one-of-a-kind company through creating new values.” As we do so, we will contribute to the society through our unique technologies, and strive to enhance our corporate value over a long term.

We would like to ask you, our shareholders and investors, for your continued support and patronage.
