Hayashi house

The Hayashi house was one of the four go houses of Edo period Japan. It was in effect the junior partner in the system of go schools, never providing a Meijin player. Always an ally of the Honinbo school, for traditional reasons, it didn't survive to the end of the period as truly independent. Its headship went to Honinbo Shuei, and when he became also Honinbo head, it was de facto merged into the Honinbos.

From the second head onwards, the head of house when playing was known as Hayashi Monnyū.
