The role of the Tule Lake Committee (TLC) is to: (i) to educate the general public of the government's forced and unconstitutional imprisonment of over 120,000 men, women and children of Japanese ancestry into ten concentration camps; (ii) to recognize the unique role of the Tule Lake camp, which was converted into a segregation center to incarcerate those from all of the camps who resisted their imprisonment and were deemed disloyal; and (iii) to preserve the history and experiences of the inmates of the Tule Lake Segregation Center and their struggles to cope with an unjust imprisonment and harsh conditions of the Segregation Center and their rejection by their own government. 

The Tule Lake Committee was created in 1978 as an all-volunteer, non-profit organization.  Key to its role, the TLC has been instrumental in organizing bi-annual pilgrimages to the Tule Lake site.  The up-coming one in 2014 will be the 20th official  Tule Lake pilgrimage, with an expected attendance of 350. 

Since 2000, the Tule Lake Committee has worked to preserve the Tule Lake Segregation Center, supporting designation as a National Historic Landmark (2006), the highest level of recognition for a historically significant property, and advocating the site gain government protection, becoming a National Monument (2008). The Tule Lake Committee raised half million dollars in grant funds to restore surviving concentration camp structures, receiving grants from the California Civil Liberties Public Education Program, the California Cultural and Historic Endowment, the Save America's Treasures program, the NPS' Japanese American Confinement Sites Program and the McConnell Foundation. Support for oral histories and outreach activities for the NPS Tule Lake Unit was assisted by grants from the Cal Humanities program and the California Civil Liberties Public Education Program. 

The Tule Lake Committee's preservation efforts have been aided by hundreds of individual donors and its pilgrimages made possible by the hard work of  hundreds of volunteers. 

The Tule Lake Committee is an all-volunteer 501(c)(3) tax exempt non profit corporation.
