This report discusses the results of a survey on homecoming cherry blossoms in Adachi Ward, Tokyo, conducted by the nonprofit organization Arakawa Gakkai since from 2021 to 2024 (the survey is still ongoing). The homecoming cherry blossom refers to cherry trees that originated on the banks of the Arakawa River in Adachi-Ward and were migrated to the United States. Their descendants were then brought back from the United States and planted in Japan. Chapter 1 provides a brief description of homecoming cherry blossoms and the background of our survey. Chapter 2 describes how cherry trees planted on the banks of the Arakawa River were transferred to the United States and brought back to Adachi Ward. Chapter 3 describes the current status of homecoming cherry blossoms planted in all elementary and junior high schools in Adachi Ward, Japan—specifically, the number of blossoms planted there. Chapter 4 describes the results of interviews with school officials and teachers regarding the use of homecoming cherry blossoms. The findings described in this report are useful for future academic research, as the blossoms are a unique local resource in Adachi Ward and should be preserved for future generations.
