History

From The Chess Variant Pages:

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 janggi in Korea. Sometime in the tenth to twelfth 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 (新猿楽記) (1058–1064) by Fujiwara Akihira. The oldest archaeological evidence is a group of 16 shogi pieces excavated from the grounds of Kōfuku-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, Nichūreki (二中歴) (c. 1210–1221), a collection based on the two works Shōchūreki (掌中歴) and Kaichūreki (懐中歴), describes two forms of shogi, large (dai) shogi and small (shō) 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 Nichūreki states that one wins if one's opponent is reduced to a single king, indicating that drops had not yet been introduced. According to Kōji 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. The drunken elephant steps one square in any direction except directly backward, and promotes to the prince, which acts as a second king and must also be captured along with the original king for the other player to win. Around the 15th century, the rules of dai shogi were simplified, creating the game of chu shogi. Chu shogi, like its parent dai shogi, contains many distinct pieces, such as the queen (identical with Western chess) and the lion (which moves like a king, but twice per turn, potentially being able to capture twice, among other idiosyncrasies). The popularity of dai shogi soon waned in favour of chu shogi, until it stopped being played commonly. Chu shogi rivalled sho shogi in popularity until the introduction of drops in the latter, upon which standard shogi became ascendant, although chu shogi was still commonly played until about World War II, especially in Kyoto.

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 present in sho shogi. There is no clear record of when drops were introduced, however.

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. It is thought that these were played to only a very limited extent, however. 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 (名人)). During the reign of the eighth shōgun, 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 Ōhashi and Itō 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 (将棋同盟社) was formed, and in 1924, the Tokyo Shogi Association (東京将棋連盟) was formed. This was an early incarnation of the modern Japan Shogi Association (日本将棋連盟, nihon shōgi renmei), or JSA, and 1924 is considered by the JSA to be the date it was founded.

In 1935, meijin Kinjirō Sekine stepped down, and the rank of meijin came to be awarded to the winner of a Meijin title match (名人戦, meijin-sen). Yoshio Kimura (木村義雄) became the first Meijin under this system 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 Ryūō title match (竜王戦, ryūō-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.

After the Second World War, SCAP (occupational government mainly led by US) tried to eliminate all "feudal" factors from Japanese society and shogi was included in the possible list of items to be banned along with Bushido (philosophy of samurai) and other things. SCAP's reason for banning shogi was that the game uniquely utilized captured pieces. SCAP insisted that this could lead to the idea of prisoner abuse. Kozo Masuda, then one of the top professional shogi players, when summoned to the SCAP headquarters for an investigation, criticized such understanding of shogi, instead insisting that chess that potentially contained the idea of prisoner abuse, because opposing pieces are removed permanently, while shogi gives prisoners the chance to get back into the game. Masuda also argued that chess contradicts the ideal of gender equality in western society because the king shields itself behind the queen and runs away. Masuda's assertions are said to have eventually led to the exemption of shogi from the list of items to be banned.
