In 1882, the university had the department of political science and economics, law, and physical science. Along with these departments, an English language course was established, where the students of all the departments could learn English. Three years later, the department of physical science was closed because it had too few applicants. The department of literature was established in 1890, the department of education in 1903, the department of commerce in 1904, and the department of science and engineering in 1908. Although Waseda formally adopted the term university in its title in 1902 it was not until 1920 that, in common with other Japanese schools and colleges, it received formal government recognition as a university under the terms of the University Establishment Ordinance. Thus Waseda became, with Keio University, the first private university in Japan. Much of the campus was destroyed in the fire bombings of Tokyo during World War II, but the university was rebuilt and reopened by 1949. It has grown to become a comprehensive university with two senior high schools and school of art and architecture. In June 12, 1950, sixty police raided Waseda University and seized copies of a Communist-inspired open letter to General MacArthur. The open letter to MacArthur was once read at a Communist-sponsored rally a week earlier. The letter demanded a peace treaty for Japan that would include Russia and Communist China, withdrawal of occupation forces, and the release of eight Japanese sent to prison for assaulting five U.S soldiers at a Communist rally. A police official said most meetings at Waseda would be banned in the future because "political elements" might try to utilize them. Yuichi Eshima, Vice-Chairman of the Students Autonomy Society, said the police action "stupefied" students and professors, and that "This is worse than the prewar peace preservation measures." Ōkuma had long desired to create an academic cap so distinctive that someone wearing the cap would immediately be identified as a Waseda student. The chief tailor of Takashimaya, Yashichiro, was called upon to design a cap in three days. Each square cap was stamped on the inside with the student's name, his department, the school seal and the legend, "This certifies that the owner is a student of Waseda". Thus, the cap served as a form of identification, and effectively a status symbol. The cap, with its gold-braided badge, is registered as a trademark. On October 21, 2007, Waseda University celebrated its 125th anniversary. Ōkuma often talked about the "125 years of life" theory: "The lifespan of a human being can be as long as 125 years.
