The Timeless Journey of Go
Origins in Ancient China
Known as Weiqi in China, Go is the oldest board game continuously played today. Legends attribute its invention to Emperor Yao (c. 2300 BC), though its roots likely lie in ancient divination and military strategy.
The Golden Age: The Edo Period (1603–1868)
Under the Tokugawa Shogunate, Go was transformed from a pastime into a government-sanctioned art form. The iemoto system established four great houses (Hon’inbō, Inoue, Yasui, and Hayashi), each supported by official stipends.
| House Name | Strategic style | Historic Role | Affiliation |
|---|---|---|---|
| Hon’inbō | Whole-board innovation & fuseki theory | Most prestigious; consistent producer of Meijins | Nichiren Sect |
| Inoue | Conservative, precise, and traditional | Main political rival to Hon’inbō | Jodo Shu |
| Yasui | Tactical sharpness and local fighting | Focused on pragmatic, effective play | Jodo Shu |
| Hayashi | Supportive and auxiliary | Often allied with the Hon’inbō house | Nichiren Sect |
The Meijin Godokoro
The Meijin Godokoro was the supreme authority in the Go world. The Meijin (Master) was the undisputed strongest player of the era, while the Godokoro (Official Tutor) coordinated the annual Oshirogo (Castle Games) held at Edo Castle in the Shogun’s presence.
Because the title carried immense political power, its attainment was frequently a source of bitter conflict. Matches like the 1835 "Blood-Vomiting Game" were proxies for house supremacy.
Fall of the System & Technical Legacy
The political maneuvering eventually eroded the system. Following Hon'inbo Jowa's forced retirement in 1839, a vacuum in the Meijin title led to surprising losses against international delegations.
Despite the tragic end of players like **Akaboshi Intetsu**, his technical legacy persists through theGenran (1833), a collection of 69 advanced life-and-death problems still studied by professionals today.
The AI Revolution
