Japanese Surname
Officially, among Japanese names there are 291,129 different Japanese surnames, as determined by their kanji, although many of these are Japanese orthography, pronounced and romanization of Japanese, romanized similarly. Conversely, some surnames written the same in kanji may also be pronounced differently. The top 10 surnames cover approximately 10% of the population, while the top 100 surnames cover slightly more than 33%. This ranking is a result of an August 2008 study by Meiji Yasuda Life, Meiji Yasuda Life Insurance Company, which included approximately 6,118,000 customers of Meiji Yasuda's insurance and annuities.

Reiko Miyaoka
Reiko Miyaoka ( ja, 宮岡 礼子, born 1951) is a Japanese mathematician and professor at Tohoku University, known for her research on hypersurfaces. In 2001 she won the Geometry prize of the Mathematical Society of Japan. She received her Ph.D. in 1983 from Tokyo Institute of Technology. Her husband Yoichi Miyaoka is a mathematician who works in algebraic geometry and who proved (independently of Shing-Tung Yau's work) the Bogomolov–Miyaoka–Yau inequality in an Inventiones Mathematicae paper.

Yoichi Miyaoka
is a mathematician who works in algebraic geometry and who proved (independently of Shing-Tung Yau's work) the Bogomolov–Miyaoka–Yau inequality in an Inventiones Mathematicae paper. In 1984, Miyaoka extended the Bogomolov–Miyaoka–Yau inequality to surfaces with quotient singularities, and in 2008 to orbifold surfaces. Doing so, he obtains sharp bound on the number of quotient singularities on surfaces of general type. Moreover, the inequality for orbifold surfaces gives explicit values for the coefficients of the so-called Vojta's conjecture, Lang-Vojta conjecture relating the degree of a curve on a surface with its geometric genus.
