Part of the power of Witness to Hiroshima lies in Keiji Tsuchiya’s empathetic connection between the people who died in Hiroshima and horseshoe crabs that are perishing from the destruction of their habitat. Mr. Tsuchiya, who has devoted over forty years of his life to preserving the horseshoe crab, regularly emphasizes the commonalities of all living creatures and the importance of protecting our environment. It is our hope that teachers in various subjects will use this film to explore one of the earth’s most fascinating creatures, the horseshoe crab.

NOTE: The majority of materials about the Japanese horseshoe crab have been published in Japanese. However there is an abundance of information in English about the Limulus polyphemus, the horseshoe crab species found in the United States. Since all horseshoe crab species are very similar, we refer English speaking teachers and students to English language sites and sources found in the lesson plan.
