Reason for nomination Taro Nakagome
After assuming the position of President in June 2024, Taro Nakagome has overseen Group
management and has promoted company integration as well as business portfolio selection and concentration. Recently, he has achieved two consecutive periods of business performance recovery by strengthening profitability. In the medium- to long-term, he has taken the helm of growth centered on the retail service strategy and has led transformation looking ahead to the 100th anniversary of the Company's founding and beyond. In light of these achievements and leadership, the Company believes that he will contribute to the sustainable growth of the Group and increase its corporate value, and has therefore continued to nominate him as a candidate for Director.
Tetsuya Nakamura
Tetsuya Nakamura possesses deep knowledge of governance, risk management, and management strategy, and has abundant experience, including having served as a director or executive officer at a major financial institution. He joined the Company in October 2019, assuming responsibility for internal auditing. Since June 2024, as a Director, he has been responsible for corporate planning, risk management, and the IT department, and has demonstrated his capabilities in promoting management strategy, selection and concentration of businesses, and strengthening of the management control system. The Company believes that his management skills will contribute to the sustainable growth of the Group and increase its corporate value, and has therefore continued to
nominate him as a candidate for Director.
Nobuhiro Nakagawa
Nobuhiro Nakagawa has led organizational management and the establishment of business foundations as Representative Director and President of Sinanen Co., Ltd., which was established through the integration of four companies, and has been deeply involved in the issues and direction of not only Sinanen Co., Ltd. but the entire Group. While Sinanen Co., Ltd. plays an important role as a core company of the Group, the Company believes that having him concurrently serve as a Director of the holding company will enable the reflection of the operating company's on-site perspective and managerial insight into Group management, thereby contributing to the sustainable growth of the Group and increasing its corporate value, and has therefore nominated him as a candidate for Director.
Hiroyuki Ohashi
Hiroyuki Ohashi has broad insight on corporate management and finance across a wide range of business areas, and has abundant experience, including having served as a director or executive officer of multiple companies. As the Company's Outside Director to date, he has contributed to appropriate management decision-making from a practical business perspective regarding management strategy and the status of business execution. The Company believes that, as an Outside Director who is an Audit/Supervisory Committee Member going forward, he will be able to contribute to the enhancement of the Company's corporate value by utilizing his abundant experience in corporate management and finance and supervising the execution of duties by Directors. For the above reasons, we have nominated him as a candidate for Outside Director who is an Audit/Supervisory Committee Member.
Tomoko Nambu
Tomoko Nambu possesses advanced expertise and broad insight in the fields of corporate legal affairs, intellectual property rights, international transactions, and compliance as an attorney-at-law, patent attorney, and New York State attorney. Based on her many years of experience and specialized knowledge as an attorney, the Company believes that she will be able to supervise the execution of duties by Directors from an independent standpoint and perform appropriate audits as an Audit/Supervisory Committee Member. For the above reasons, we have nominated her as a candidate for Outside Director who is an Audit/Supervisory Committee Member.
Hidehiko Nishiyama
Hidehiko Nishiyama possesses broad knowledge regarding corporate management, risk management, and crisis response through his many years of experience in energy policy and trade administration. He has also held important positions in corporate planning and overseas business at private companies. Based on his abundant experience cultivated from both public and private sector perspectives, the Company believes that he will be able to provide advice on growth strategies, including Energy Business and new businesses, and supervise the execution of duties by Directors from an independent standpoint and perform appropriate audits as an Audit/Supervisory Committee Member. For the above reasons, we have nominated him as a candidate for Outside Director who is an Audit/Supervisory Committee Member.
