Known as the «Godfather of Sudoku, Kaji created the puzzle to be easy for children and others who didn’t want to think too hard. Its name is made up of the Japanese characters for «number and «single, and players place the numbers 1 through 9 in rows, columns and blocks without repeating them.

Ironically, it wasn’t until 2004 when Sudoku became a global hit, after a fan from New Zealand pitched it and got it published in the British newspaper The Times. Two years later, Japan rediscovered its own puzzle as a «gyakuyunyu, or «reimport.

Kaji was chief executive at his puzzle company, Nikoli Co., until July and died Aug. 10 at his home in Mitaka, a city in the Tokyo metro area.

Maki traveled to more than 30 countries spreading his enjoyment of puzzles. Sudoku championships have drawn some 200 million people in 100 countries over the years, according to Tokyo-based Nikoli.

Born in the main northern island of Hokkaido, Maki started Japan’s first puzzle magazine after dropping out of Keio University in Tokyo. He founded Nikoli in 1983, and came up with Sudoku about the same time.

Yoshinao Anpuku, who succeeded Kaji as Nikoli’s chief executive, said Kaji made friends easily and had a «unique and playful approach toward life.

«Our mission is to pursue Maki’s vision and possibilities, Anpuku said.

Nikoli has provided original puzzles to more than 100 media companies, 10 of them foreign ones.

Major Japanese newspaper Mainichi in its obituary credited Kaji for starting the puzzle sections at bookstores, as well as introducing the word «Sudoku into the Oxford English dictionary.

Kaji is survived by his wife Naomi and two daughters. Funeral services have been held among close family. A separate memorial service is being arranged by Nikoli, but details were still undecided.
