Transition of Leadership at Shinwa Electric Industry: A New Chapter for Growth

Leadership Transition in Shinwa Electric Industry



In March 2025, LBPI Inc., a wholly-owned subsidiary of Long Black Partners Group, successfully acquired shares of Shinwa Electric Industry Co., Ltd., located in Setagaya, Tokyo. Following this acquisition, the Keisho Japan Fund—under which LBPI operates—has committed itself to reinforce the operational foundation of Shinwa Electric Industry.

Recently, a significant leadership change took place at Shinwa Electric Industry, marking a new era for the company as Miki Onoda assumed the role of CEO on July 1. She takes over the reins from Kazuya Aoyama, who dedicated many years to nurturing the company's growth and reputation. Under Aoyama’s leadership, Shinwa Electric solidified its standing in the industry by specializing in safe and dependable railway signal safety equipment construction.

Miki Onoda aims to build upon the legacy established by Aoyama. By continuing the tradition of excellence he fostered, she is poised to lead the company towards further growth and success. The Long Black Partners Group stands firmly behind the new management structure and is committed to supporting Shinwa Electric Industry's future advancements.
