In 1967, when the Six-Day War broke out, Teshima wrote a telegram to the Makuya students in Israel: "Stay as long as you can and help Israel." The students, accordingly, volunteered to aid Israel during the war. In 1973, when the Yom Kippur War broke out, the State of Japan supported Arab countries, caving in to an Arab oil embargo. This diplomatic policy frustrated Teshima. Despite his serious illness (terminal cirrhosis), Teshima, then, organized, with 3,000 of his adherents, a campaign for Israel in front of the National Diet Building in Tokyo. It was the first pro-Israel demonstration ever held in Japan. The campaign received wide coverage in the press, radio, and television. However, it also worsened Teshima's illness and he died three weeks later on Christmas Day 1973.
