Almost seventy years have passed since the Second World War, and there are very few physical reminders of it. The people who personally remember the war are quite old now. Trees damaged during the war are historical relics, and their number and distribution are unknown because there has been little research conducted on these trees. In this study, we surveyed three wards—Taito, Sumida, and Koto—which were the main targets of the air raids on Tokyo on March 10, 1945, to establish the distribution and number of war-damaged trees as well as their present condition. We determined that 1) war-damaged trees were unevenly distributed and mainly concentrated in some public parks, temple precincts and edge of the target area of air raids; 2) there may be previously undiscovered war-damaged trees; 3) some of the trees that were earlier recognized were now gone; 4) carbonation and hollowing are the main features of war-damaged trees, with 60.2% showing carbonation and 52.6% showing hollowing; 5) the degree of these damages and vigor of the trees were not correlated in ginkgo trees; however, the other species seemed to be heavily influenced. More study of the relation between damage type and vigor is required.

<p>Nearly 70 years have passed since the Second World War and very few physical reminders of it are present. The people who remember the war are now quite old. Trees damaged during the war are historical relics; however, their number and distribution are unknown because little research has been conducted on this subject. In the present study, we surveyed three wards—Taito, Sumida, and Koto, which were the main targets of air raids on Tokyo on March 10, 1945, and established the number, distribution, and present condition of the war-damaged trees. We determined the approximate number of the war-damaged trees, which was not recorded in previous studies. Then, we newly discovered 80 estimated war-damaged trees and 114 more trees for which more evidence was needed. We found that war-damaged trees were unevenly distributed and they were mainly concentrated in some public parks, temple precincts, and on the edges of air raid targets. Their distribution was particularly dense at the end of a fire spread. In summary, we conclude that we need to preserve these trees, not only individually, but as specific areas or precincts because of their historical significance.</p>
