Corporate Governance | Board Members | Organisation | Management 

Sumida recognizes corporate governance is one of the most important topics of management and that its basis is to secure the transparency and efficiency of management to respond to the expectations of stakeholders and to continuously enhance corporate value of the company.

In April 2003, Sumida shifted to a Company with Committees System to strengthen corporate governance of the company. In the System, Committees in which outside directors occupy the majority are established in order to improve management transparency. Executive Officers concentrate on business execution while the Board specializes in the supervision of their execution – thus the System clearly separates "Management" and "Governance" in order to make both organizations function effectively.
