"The world's first chess variant Chaturanga arose in India in approximately the seventh century AD. From there it migrated both westward and northward, mutating along the way." "The western branch became Shatranj in Arabia and Orthodox Chess in Europe. The northern branch became Xiangqi in China and Changgi in Korea." "Sometime in the 10th to 12th centuries, 'chess' crossed the channel to Japan where it spawned a number of interesting variants." "One of these was called 'Small Shogi'." "Eventually, Small Shogi (though it went through many forms) won out over the larger variants and is now referred to simply as 'Shogi'." "It is certain that Shogi in its present form was played in Japan as early as the 16th century."

It is not clear when chess was brought to Japan. The earliest generally accepted mention of shogi is Shin Saru Gakuki? (1058?1064) by Fujiwara Akihira. The oldest archaeological evidence is a group of 16 shogi pieces excavated from the grounds of K?fuku-ji in Nara Prefecture. As it was physically associated with a wooden tablet written on in the sixth year of Tenki (1058), the pieces are thought to date from that period. These simple pieces were cut from a writing plaque in the same five-sided shape as modern pieces, with the names of the pieces written on them.

The dictionary of common folk culture, Nich?reki? (ca. 1210?1221), a collection based on the two works Sh?ch?reki? and Kaich?reki , describes two forms of shogi, large (dai) shogi and small (sh?) shogi. These are now called Heian shogi (or Heian small shogi) and Heian dai shogi. Heian small shogi is the version on which modern shogi is based, but the Nich?reki states that one wins if one's opponent is reduced to a single king, indicating that drops had not yet been introduced. According to K?ji Shimizu, chief researcher at the Archaeological Institute of Kashihara, Nara Prefecture, the names of the Heian shogi pieces keep those of chaturanga (general, elephant, horse, chariot and soldier), and add to them the five treasures of Buddhism (jade, gold, silver, katsura tree, and incense).

Around the 13th century the game of dai shogi developed, created by increasing the number of pieces in Heian shogi, as was sho shogi, which added the rook, bishop, and drunken elephant from dai shogi to Heian shogi. Around the 15th century, the rules of dai shogi were simplified, creating the game of chu shogi in a form close to the modern game. It is thought that the rules of standard shogi were fixed in the 16th century, when the drunken elephant was removed from the set of pieces. However, there is no clear record of when drops were introduced.

In the Edo period, shogi variants were greatly expanded: tenjiku shogi, dai dai shogi, maka dai dai shogi, tai shogi, and taikyoku shogi were all invented. However, it is thought that these were only played to a very limited extent. Both standard shogi and go were promoted by the Tokugawa shogunate. In 1612, the shogunate passed a law giving endowments to top shogi players (Meijin). During the reign of the eighth shogun, Tokugawa Yoshimune, castle shogi tournaments were held once a year on the 17th day of Kannazuki, corresponding to November 17, which is Shogi Day on the modern calendar.

The title of meijin became hereditary in the ?hashi and It? families until the fall of the shogunate, when it came to be passed by recommendation. Today the title is used for the winner of the Meijin-sen competition, the first modern title match. From around 1899, newspapers began to publish records of shogi matches, and high-ranking players formed alliances with the aim of having their games published. In 1909, the Shogi Association was formed, and in 1924, the Tokyo Shogi Association was formed. This was an early incarnation of the modern Japan Shogi Association , founded in 1997.

In 1935, meijin Sekine Kinjir? stepped down, and the rank of meijin came to be awarded to the winner of a Meijin title match. Yoshio Kimura becoming the first Meijin in 1937. This was the start of the shogi title matches (see titleholder system). After the war other tournaments were promoted to title matches, culminating with the Ry?? title match (ry??-sen?) in 1988 for the modern line-up of seven. About 200 professional shogi players compete. Each year, the title holder defends the title against a challenger chosen from knockout or round matches.

The closest cousin of Shogi in Chaturanga family is Makruk of Thailand. Not only the similarity in distribution and movements of the pieces but also the names of Shogi pieces suggest intimacy between Shogi and Makruk by its Buddhist symbolism (Gold, Silver, Cassia and Incense), which isn't recognised in Chinese chess at all. In fact, Chinese chess and its East Asian variants are far remoter relatives than Makruk. Though some early variants of Chaturanga more similar to Shogi and Makruk are known to have been played in Tang Dynasty China, they are thought to have been extinguished in Song Dynasty China and in East Asia except in Japan probably owing to the prosperity of Chinese chess.
