Overview
In practice these events almost always are based in East Asian countries with a professional system: in Japan for go and shogi, and in China,Other systems
In go, the first titleholder system of the modern pattern was the Honinbo tournament. Before that was introduced in the early 1940s, other systems used were the win-and-continue system, which has the advantage of low organisational overheads, and high-profile '' jubango''. There has been no ''jubango'' since 1960, but win-and-continue systems are used in South Korea. Teams matches were also popular in the 1920s. The introduction of international go events led to the adoption of new systems for those, mostly based on knockout rounds, and international titles are typically not awarded under the titleholder system. That is, the holder has to compete in the event's earlier stages, a system akin to the way tennis tournaments do it, with the champion perhaps avoiding preliminaries and being seeded into the final stages. *
