The Ireichō: Book of Names Visits the California Museum
Register to leave a mark in The Ireichō: Book of Names, a monument representing the Japanese Americans who were incarcerated during World War II.
February 14 – 19, 2026
The California Museum is honored to host The Ireichō: Book of Names, a monumental record honoring the 125,284 persons of Japanese ancestry unjustly incarcerated in U.S. government-run camps during World War II. This special installation from February 14 – 19, 2026, presented in partnership with the Japanese American National Museum and The Irei Project, is a rare opportunity for the community to engage with this profound work.
MAKE YOUR MARK
Visitors are invited to reserve a 15-minute time slot to leave a personal mark using a Japanese “hanko” stamp beneath the name of an individual in the book. Each mark contributes to the project’s goal of honoring every name in the book during its 20-month national tour, which includes stops at each of the 10 former War Relocation Authority incarceration camps. The Sacramento stop, which will include an opening ceremony at Walerga, serves to represent the 15 temporary Assembly Centers.
Registration is required to stamp a name in the book. Wheelchair accessible.

About the Ireicho
Envisioned as a monument to memory and healing, The Ireichō represents the first comprehensive listing of individuals incarcerated under Executive Order 9066. This large-format book, developed through three years of meticulous research by University of Southern California Professor Duncan Ryuken Williams and his team, draws on archival materials such as government camp rosters, train transfer lists, and Japanese-language directories.
