Kōyō Tōya (塔矢 行洋, Tōya Kōyō), also known as Tōya Meijin, is a retired Meijin, Akira Toya's father and a holder of multiple titles.


Touya Meijin
In the anime

He is usually depicted in traditional Japanese dress and is older, his hair being gray throughout the entire series.


Koyo Toya's personality is depicted as very serious, both in his professional and private life though he is shown to have his moments of sweetness, especially with his son, Akira, whom he has great pride and affection for. His feeling for go is very similar to Sai as he stated that he will not stop playing go even after he retire as a Professional Go Player.

He is one of the world's top players and was stated by many to being able to match Hon'ninbo Shusaku.



Koyo is Sai's rival, whom he recognizes and respects, despite not knowing his full identity.

Akira Touya

Akira is Koyo's son and they are depicted as having a very close and affectionate (for them) relationship. They played go every morning when Akira was a child and Kouyou encouraged Akira to grow as a go player.

Hikaru Shindo

Koyo met Hikaru when he was 11 years old and he piqued his interest both in the children go tournament and by supposedly beating Akira (though it was actually Sai). This interest continued when Hikaru became an Insei and later a pro and Kouyou even requested to play him for his shodan game.
