Waseda University was founded in 1882 and guided by the principle of “independence of learning” (see Waseda 2010, p. 8). President Masasada Shiozawa delivered a welcome address, and in his reply Einstein remarked that he had noticed the unexpected progress of the Japanese scholarly community and that he was looking for- ward to its future contributions (see Waseda Gakuho, 10 January 1923). [103]According to both Sugimoto 2001a, pp. 10–11, and Ishiwara 1923, the title of Einstein’s fourth scientific lecture was “On the General Theory of Relativity.” [104]At the Tokyo Women’s Higher Normal School (the present-day Ochanomizu Women’s Uni- versity), a teacher training institute. The reception was presided over by the Imperial Pedagogical Association and eleven other educational associations. It was attended by one thousand people (see Taisho 11 nen Nisshi Tokyo-joshi-koto-shihan-gakkou, 29 November 1923). [105]Einstein visited the Division of Imperial Court Music at the Imperial Household Agency and attended a performance of gagaku, Japanese ancient court music and dance (see Yomiuri Shinbun, 1 December 1922, and Aichi 1923, p. 300). [106]According to Sugimoto 2001a, pp. 10–11, the title of Einstein’s fifth scientific lecture was “On the Equation of the Gravitational Field.” Yet according to Ishiwara 1923, it was entitled “General Theory of Relativity.” Takuro Tamaru (1872–1932) was Professor of Physics at Tokyo Imperial University. Uzumi Doi (1895–1945) was a graduate student under Hantaro Nagaoka at Tokyo Imperial Uni- versity and lecturer in physics at the prestigious First Higher School. For his book challenging the theory of relativity, see Doi 1922c. According to press reports, Doi, who had criticized Einstein’s the- ories, admitted that he had been wrong and asked Tamaru to read his statement in German to that ef- fect (see Tokyo Asahi Shinbun, 2 December 1922, and Kahoku Shimpo, 1 December 1922). Earlier, Einstein had confirmed that he had read the pamphlet Doi had sent him to Berlin and that it merited “serious study.” However, he was not concerned that it would pose a challenge to the theory of rela- tivity (see Tokyo Nichinichi Shinbun and Osaka Mainichi Shinbun, 18 November 1922). For Doi’s di- ary during Einstein’s visit, in which he retracted his rejection of his own theory merely half an hour later, see Uzumi Doi, Diary, 24 November to 2 December, 1922 [JPS]). On the controversy between Doi and Keiichi Aichi over Einstein’s theories, see Osaka Mainichi, English Daily Edition, 5 Novem- ber 1922. The welcoming message from the students of the university is available (see Abs. 464). [107]The Danish ambassador was Niels Höst (1869–1953). [108]According to Sugimoto 2001a, pp. 10–11, Einstein’s sixth (and final) scientific lecture was entitled “On the Cosmological Problem.” However, according to Ishiwara 1923, it was entitled “Gen- eral Theory of Relativity.” To mark the end of the lecture series, a commemorative photo of Einstein and Japanese scientists was taken beside Sanshiro Pond at the heart of the university. The photograph was presented to Einstein with an autograph album signed by the faculty and students of the physics department. The album (see NNLBI, Albert Einstein Collection: Addenda [AR 7279]) also included a letter of appreciation written by Hantaro Nagaoka and signed by him and 124 other signatories (see Doc. 389). For a description of these events, see Ishiwara 1923, pp. 111–112. [109]The banquet was held in honor of the conclusion of the lecture series at the Imperial Hotel. It was attended by 150 scholars, writers, and employees of Kaizo-Sha. Among the attendees were Han- taro Nagaoka, Jun Ishiwara, Ayao Kuwaki, Takeo Arishima, Takuro Tamaru, Tetsujiro Inoue, Tora- hiko Terada, and Shinzo Koizumi (see Kahoku Shimpo, 3 December 1922, and Kaneko 1981, vol. 1, p. 259). [110]The Tokyo School of Technology (the present-day Tokyo Institute of Technology), founded in 1881. Tokio Takeuchi (1894–1944) was Assistant Professor of Physics there. [111]Einstein arrived at Sendai station at 9:17 P.M. (see Governor of Miyagi Prefecture to Minister of Diplomacy, 6 December 1922 [JTDRO, Diplomatic R/3.9.4.110.5]). Kotaro Honda (1870–1954) and Keiichi Aichi (1880–1923) were both Professors of Physics at Tohoku Imperial University at Sen- dai. They traveled from Sendai to Kooriyama station, roughly midway between Tokyo and Sendai (see Kahoku Shimpo, 4 December 1922). [112]The prominent physicists at Tohoku Imperial University were Shirota Kusakabe, Yoshitoshi
