We compiled below a short table listing the most common Japanese electrolytic capacitor manufacturers that you will find on motherboard and power supplies. We also included their typical markings (as some of them don’t print their names on the capacitors) and also pictures with examples of Japanese capacitors from these brands. There is one important exception. Even though Toshin Kogyo is a Japanese company, they sell rebranded Taiwanese capacitors, from OST.
