Following the U.S. Supreme Court decision Ex parte Mitsuye Endo (1944), most Japanese Americans were free to leave Poston Incarceration Camp after January 2, 1945. (At the end of World War II [1939-1945], all Japanese Americans were allowed to leave.) The Endo case allowed the Office of Indian Affairs (OIA) to move forward with its “colonization” program at the Colorado River Indian Reservation (CRIR). As Japanese Americans began to move out, Hopi “colonists” began to move in. In this lesson, students will unpack the term “colonize” and learn about the colonization program that took place at Poston after World War II. Students will examine the implications of historical freedom denied for Native Americans and its implications for Japanese Americans in the narrative film, The Blue Jay. Students will reflect on the heritage of Poston and learn about the relationship between the Colorado River Indian Tribes (CRIT) and Japanese Americans post-WWII to the present.
Students will:
- Examine the history of the “colonization” program at Poston Incarceration Camp after World War II.
- Assess the motivations of the Colorado River Indian Tribes (CRIT) Tribal Council for opposing an incarceration camp on their reservation.
- Discuss the legacy of Poston Incarceration Camp.
Poston After World War II Essay:
On December 18, 1944, the U.S. Supreme Court declared that, based on the decision
Ex parte Mitsuye Endo (1944), Japanese Americans could no longer be detained in
incarceration camps and were free to leave after January 2, 1945. In their decision, the Supreme Court unanimously held that the War Relocation Authority (WRA) could not continue to confine Japanese Americans who were “concededly loyal” meaning they properly answered the “loyalty questionnaire.” The questionnaire required incarcerees to affirm their allegiance to the United States and agree to service in the U.S. military if ordered to. (Those who were deemed disloyal were sent to Tule Lake Incarceration Camp, which did not close until March 20, 1946.) Although the
Ex parte Endo case did not weigh in on the
constitutionality of incarcerating Japanese Americans, it did allow Japanese Americans to leave the camps and return to the West Coast.
With the anticipated departure of the Japanese American incarcerees, the Office of Indian Affairs (OIA) could now move forward with their long-awaited colonization* program. The OIA had been planning the colonization program since establishing the Colorado River Indian
Reservation (CRIR) in 1865. Its goal was for thousands of Native American tribal members to live and work on the reservation. The OIA planned to recruit tribes living along the Colorado River. The establishment of
Poston Incarceration Camp, referred to as the
Colorado River Relocation Center by the U.S. government, as a site for Japanese American incarceration during World War II (1939-1945), provided the necessary funding and labor to move their plan forward.
The OIA created an official document, “
Ordinance No. 5–Reserving a Portion of the Colorado River Indian Reservation for Colonization,” to outline the terms of the colonization. The ordinance stipulated that Native Americans who lived on tribal land where water resources were inadequate could move to CRIR. The
tribes living along the Colorado River
tributaries at the time included the Huyalapai, Hopi, Navajo, Apache, Zuni, Papago, Supai, Yuma, Chemehuevi, and Mohave. On February 3, 1945, the CRIT Council signed Ordinance No. 5, giving its official approval to allow for the colonization of other southwestern Native Americans to Poston. However, in the early 1950s, the CRIT Tribal Council challenged the validity of the ordinance, arguing they had been forced to sign it. Negotiations between the CRIT Tribal Council and OIA continued until the mid-1950s, as the two groups disputed over who owned the legal
title to the reservation land. In 1964, the legal title to the CRIR was finally settled in favor of CRIT. This was a win for the Native American community whose land has been forcibly stolen by the United States for centuries.
While these negotiations were happening, Ordinance No. 5 was in effect and the colonization program was underway. The OIA worked to recruit Native Americans to relocate to Poston with promises of land to farm, abundant water, and housing. Many Native Americans were reluctant to leave their
ancestral lands and relocate to Poston. They did not want to give up their own lands, even if it was dry. Those who did move were motivated by more fertile farming land. The colonization program officially began with the first arrival of Hopi colonists on September 1, 1945. At the time, several hundred Japanese American incarcerees were still living in the Poston camps. They were packing and making arrangements to leave Poston. When the Hopi families arrived at Poston Incarceration Camp, they moved into barracks that had just been vacated by Japanese Americans. Many Japanese Americans left their dishes, furniture, and other items in the barracks.
During the ten years (1945-1955) in which the colonization program was in effect, many other Native Americans from different tribes arrived at Poston. Many eventually returned to their former reservations to reunite with family or community, or were otherwise dissatisfied with life on the CRIR. A large number of Hopi and Navajo colonists stayed and became members of the CRIT. Today, the official seal of CRIT contains four tribes: Mohave, Chemehuevi, Hopi, and Navajo. Agriculture is the main business on the CRIT land. Some CRIT members are independent farmers, and others
lease their farmland to non-Native farmers. They use the irrigation system built by the Japanese American laborers to produce cotton, alfalfa, wheat, feed grains, lettuce, and melons.
The adobe school buildings built by Japanese Americans were used by CRIT and the Parker School District until 1980. While some of the adobe buildings have been demolished, others still stand today.
Since the 1980s, many Japanese Americans who were incarcerated at Poston have visited the site. They have formed friendships with CRIT members and undertaken several programs and projects together. In 1992, several former incarcerees and CRIT members worked together to plan and build the Poston Memorial Monument. The monument was designed by Ray Takata (1934-2006), an architect, and Stephan Hamamoto (years unknown), a civil engineer. Former incarcerees, Ted Kobata (1924-2016) and Jim Namba (1923-2021) from Sacramento, built the Poston Memorial Monument dedicated in October 1992. The concrete single column monument symbolizes “Unity of Spirit.” It has a hexagonal-shaped base that represents a Japanese stone lantern. The Poston Memorial Monument is an important symbol. It serves as a reminder to those who live on the CRIR, and others who pass by, to never forget the experiences endured by the Japanese Americans incarcerated there, the injustices they faced at the hands of their own government, and the contributions they made to the community there.
The connections that bind the CRIT and Japanese American incarcerees together is fittingly inscribed and exhibited on the monument’s bronze plates. While these two groups had little contact during World War II, in the years since, they have formed a connection rooted in their shared
disenfranchisement. Though the CRIT was unable to stop the incarceration of Japanese Americans on their reservation, they spoke up in opposition to their land being used to unjustly detain another group, knowing what it was like to be forcibly relocated by the U.S. government. These two disenfranchised groups of people shared a desert home for a brief period of time. Through their relationship, the CRIT Tribal Council and Japanese Americans now share their histories for the public to observe, reflect on, and appreciate.
This text is an excerpt from the “Sharing a Desert Home: Life on the Colorado River Indian Reservation” by Ruth Y. Okimoto. It has been adapted for reading accessibility and clarity. Access to the original text can be purchased through the Poston Community Alliance.
*In “Sharing a Desert Home,” Okimoto includes the following footnote in regards to the use of the terms “colonist” and “colonization”: “U.S. government officials in the 1940s used the term ‘colonists’ or ‘colonization’ without, it seems, any thought to the meaning or impact on the CRIT community. For American Indians, the words ‘colonists’ and ‘colonizaiton’ are laden with meanings of deprivation, ethnic genocide, loss of freedom, and loss of land. Although the dictionaries vary in their definition of ‘colonist’ or ‘colonization,’ the popular or general meaning ascribed to the word ‘colonist,’ for example, is when a group of people arrive to ‘take over’ a territory and dominate the land and its indigenous people. The U.S. government officials may have used the word ‘colonist’ to mean ‘an original settler or founder of a colony.’ Or defined a colony as ‘a group of people with the same interests or ethnic origin concentrated in a particular area.’ However, the term sounds strange and inappropriate in its application to the CRIR. It is inappropriate because the geographical area has been occupied for centuries by the Mohave tribe. In addition, the Japanese American detainees were prisoners, not willing colonists eager to settle a new territory. For the purpose of this article and to be true to the historical government records, I am applying the terms as they were recorded and used. I invite the readers to keep the time period and historical context in mind.”

Activity 5: Reflecting on Poston’s Heritage
- Divide students into two groups. Assign each group to one of these prompts:
- Group 1: “What were the consequences of the U.S. government’s decision to build Poston Incarceration Camp on the CRIR? How and why were Native Americans and Japanese Americans pitted against each other?”
- Group 2: “How have Japanese Americans and Native Americans worked together since World War II to preserve Poston’s heritage? What lessons about cross-cultural solidarity can we learn from this friendship?”

- Post these four topics in four corners of the classroom:
- Promoting cross-cultural solidarity
- Exercising rights in a democracy
- Engaging in intercultural communication
- Dealing with stereotypes
- Tell students that this unit touched on these four topics. Have students choose one topic that resonates with them the most and go to the corner of the classroom with that topic.
- Have students discuss the following questions while stationed at each corner:
- What does this topic mean to you? What does it look like in your everyday life?
