YOKOSUKA, JAPAN - SEPTEMBER 17: Students salute their teacher after finishing rifle training at the Japan Ground Self-Defense Force (JGSDF) High Technical School on September 17, 2014 in Yokosuka, Japan. Each year, approximately 4500 students apply to enter the one and only high school run by JGSDF, and only 300 are accepted. The boys only school was opened in 1955 and caters to students between 15 and 19 years old across three grades. 90% of graduates continue on to careers in the JGSDF. Japan's self-defense stance was changed in July 2014, with the reinterpretation of the country's war-renouncing constitution to allow the Self-Defense Forces (SDF) to exercise the right to collective self-defense, enabling the SDF to engage in military actions for countries who have close relationships with Japan.
