Mitsuhiro Shishikura (宍倉 光広, Shishikura Mitsuhiro; born November 27, 1960) is a Japanese mathematician working in the field of complex dynamics. He is professor at Kyoto University in Japan. Shishikura became internationally recognized for two of his earliest contributions, both of which solved long-standing open problems. In his Master's thesis, he proved a conjecture of Fatou from 1920 by showing that a rational function of degree d {\displaystyle d\,} has at most 2 d − 2 {\displaystyle 2d-2\,} nonrepelling periodic cycles. He proved that the boundary of the Mandelbrot set has Hausdorff dimension two, confirming a conjecture stated by Mandelbrot and Milnor. For his results, he was awarded the Salem Prize in 1992, and the Iyanaga Spring Prize of the Mathematical Society of Japan in 1995. More recent results of Shishikura include (in joint work with Kisaka) the existence of a transcendental entire function with a doubly connected wandering domain, answering a question of Baker from 1985; (in joint work with Inou) a study of near-parabolic renormalization which is essential in Buff and Chéritat's recent proof of the existence of polynomial Julia sets of positive planar Lebesgue measure. (in joint work with Cheraghi) A proof of the local connectivity of the Mandelbrot set at some infinitely satellite renormalizable points. (in joint work with Yang) A proof of the regularity of the boundaries of the high type Siegel disks of quadratic polynomials. One of the main tools pioneered by Shishikura and used throughout his work is that of quasiconformal surgery. His doctoral students include Weixiao Shen.

Motoyuki Takabatake (Japanese: 高畠素之, Hepburn: Takabatake Motoyuki; 1886 – 1928) was a Japanese journalist and political activist who completed the first full Japanese translation of Karl Marx's Das Kapital. In his youth he became a member of the small Japanese anarchist movement. During the Russian Revolution however, he began to lean in support of state socialism. Where prominent Marxists saw the state in Soviet Russia as a temporary and necessary evil needed to construct communist society, Takabatake welcomed the revolution precisely because it would lead to a strong centralized state. This led to tensions between him and other Japanese Marxists, with Takabatake becoming one of the first theoreticians of socialist nationalism in Japan. He completed the first Japanese translation of Das Kapital in 1924, though by 1926 he had left Marxism entirely, establishing the fascist Kenkokukai organization, and had prepared to establish a National Socialist Party before his abrupt death in 1928.

Baron Kantarō Suzuki (鈴木 貫太郎, Suzuki Kantarō; 18 January 1868 – 17 April 1948) was a Japanese politician and admiral who served as prime minister of Japan from 7 April to 17 August 1945, during World War II. He was prime minister at the time of Japan's surrender on 15 August. Born in Osaka, Suzuki graduated from the Naval Academy and Staff College and served in the First Sino-Japanese and Russo-Japanese Wars. He was promoted to full admiral in 1923 and served as chief of the naval general staff from 1925 to 1929. In 1945, Suzuki was appointed prime minister shortly after the start of the Battle of Okinawa and the resignation of prime minister Kuniaki Koiso. After the Potsdam Declaration by the Allies on 26 July, which called for Japan's unconditional surrender, Suzuki dismissed it with the word mokusatsu. On 14 August, Suzuki attended the conference at which emperor Hirohito made the decision to surrender over his divided cabinet. Japan surrendered the next day, and Suzuki resigned on 17 August.
