is a monthly Japanese literary magazine (), first established during the Meiji period and continuing to this day. It is published by its namesake-bearing Chà «à Âkà Âron Shinsha (formerly Chà «à Âkà Âron-sha). The headquarters is in Tokyo.
Chà «à  Kà Âron publishes a wide variety of material, including novels, photographs and reports based on various philosophical, economic, political, cultural and social topics.
The magazine was first published in January 1887 under the title in Kyoto by the , a literary group of professors and students of Ryukoku University. In 1899, the magazine changed its name to Chà «à  Kà Âron.
In the 1920s, journalist Yà «saku Shimanaka rose to become editor-in-chief and later owner of Chà «à  Kà Âron. During the World War II editors of the magazine were arrested in the Yokohama incident. In 1944 the magazine was closed down due to its anti-war sentiments but publication resumed in 1946. In 1949, ownership and control of the magazine passed to his son, Hà Âji Shimanaka, who would serve as its president for the next 45 years.
Under the Shimanakas, Chà «à  Kà Âron became one of Japan's foremost general-interest magazines, and has been cited as having a profound influence on several Japanese intellectuals. The noted author Ryà Âtarà  Shiba once stated that the magazine's history corresponded to the history of modern Japan itself. There have been numerous famous contributors to the magazine, including Princess Takamatsu, Tama Morita, Jun'ichirà  Tanizaki, Tà Âson Shimazaki, Shà Âfu Muramatsu, his grandson Tomomi Muramatsu, Yaeko Nogami, Tomoyoshi Murayama, Motojirà  Kajii, Sakuzà  Yoshino, Nanami Shiono, Shichirà  Fukazawa, and Masao Horino.
In 1960, Chà «à  Kà Âron was at the center of a major controversy that shaped the future of freedom of expression in Japan. The magazine's November 1960 issue featured a satirical story by Shichirà  Fukazawa featuring a dream sequence in which the Emperor and Empress were beheaded with a guillotine. Japanese right-wing ultranationalist groups were outraged and mounted a long series of protests and attacks aimed at Chà «à  Kà Âron in an attempt to force an apology. An initial attempt at apology was deemed too perfunctory by the rightists, and on the evening of February 1, 1961, a 17-year-old rightist named Kazutaka Komori invaded Chà «à  Kà Âron publisher Shimanaka Hà Âji's home in Shinjuku, Tokyo in an apparent assassination attempt. Shimanaka was away from home at the time, but his housekeeper was stabbed to death and his wife was seriously injured, in a terroristic attack that became known as the "Shimanaka Incident."
Shimanaka was deeply shaken by the attack on his household and issued a statement of remorse in which he repudiated Fukazawa's story as âÂÂunsuitable for print" and offered his "deepest apologies" for âÂÂhaving disturbed society to the point of causing violent incidents." Thereafter, Shimanaka forced the magazine's editor-in-chief to resign, and negotiated a deal with right-wing groups to end the attacks on Chà «à  Kà Âron in exchange for a promise to adopt a more "neutral" editorial policy. The Shimanaka incident has been cited by scholars as helping to cement in place the so-called Chrysanthemum Taboo (èÂÂã¿ãÂÂã¼, kiku tabà «, named after the Imperial family's chrysanthemum crest) in postwar Japan that informally but powerfully forbids literary or artistic expression directly featuring the Emperor or the Imperial family.
From 1985 to 1988 Motohiro Kondo served as the editor-in-chief of the magazine.
In 1994, Shimanaka resigned as president of Chà «à  Kà Âron after 45 years, succeeded by his eldest son Yukio, and became chairman of the board of directors. However two years later, in 1996, he fired Yukio and for a time the company had no president.
When Shimanaka died on April 3, 1997, it was discovered that he had co-mingled the company's finances with his own, leaving behind a massive debt of 15 billion yen. Shimanaka's wife Masako became chairman and president, but was not able to resolve the company's financial crisis. In 1999, Chà «à Âkà Âron-sha and all of its assets were bought out by the Yomiuri Shimbun newspaper company. Thereafter, the magazine's tone and content took a decidedly more politically conservative direction, in line with Yomiuri<nowiki>'</nowiki>s broader editorial stance.
As of 2006 the circulation of Chà «à  Kà Âron was 40,975 copies.
