Kawabata's novel is a fictionalisation of the real life final tournament of Go master, Hon'inbō Shūsai (photo), which he covered for a newspaper.
Knowing the game would undoubtedly enhance the experience, but it's not necessary (luckily!) as the novel is actually about the characters of the Old Master and the Young Pretender, and how they respond to the stress of a historic match that will define the future of a cultural institution.⬇️
