Soka Gakkai is a lay-based, modern Nichiren practice that originated in Japan and has since spread to over 192 countries and territories around the world. The organization follows a hierarchical structure, with a central leadership and various levels of local and regional leadership.

At the top of the hierarchy is the Soka Gakkai International (SGI) President, who is elected by the SGI General Council, a group of representatives from each country and territory where Soka Gakkai is active. The SGI President is responsible for overseeing the overall direction and activities of the organization on a global scale.

Below the SGI President are the regional leaders, who are responsible for overseeing the activities of Soka Gakkai in their respective regions. These regions are divided into zones, which are further divided into districts. Each district has a district leader who is responsible for the activities and well-being of the members in their district.

At the local level, Soka Gakkai is organized into local chapters, which are led by a chapter leader. These chapters are further divided into smaller groups, called districts, which are led by a group leader. These leaders are responsible for the day-to-day activities and support of the members in their respective groups and districts.

Within this hierarchical structure, there are also various committees and departments that focus on specific areas of the organization's activities, such as youth, women, education, and peace initiatives. These committees and departments are led by appointed leaders who work closely with the regional and local leaders to implement various programs and initiatives.

It is important to note that while there is a clear hierarchical structure in Soka Gakkai, the organization emphasizes the importance of democracy and grassroots participation. Members are encouraged to actively participate in the decision-making process and to take on leadership roles within their local communities.

Overall, the structure of Soka Gakkai allows for effective coordination and communication between the different levels of leadership, ensuring that the organization's activities and goals are aligned and carried out in a unified manner. This structure also allows for a strong sense of community and support among members, as they work together towards the common goal of promoting peace, culture, and education through the practice of Nichiren Buddhism.
