"Bukou-yawa" was written by Shouemon Maeno, the vassal of Nobunaga who made a lot of exploits at "Sunomata one night castle", and also was the Hideyoshi's close associate, as the record of the Maeno family history. The story also describes how Hideyoshi served Nobunaga, all about the battles Nobunaga commanded before he unifies the country. This story is written in very detail about Nobunaga and Hideyoshi, too.
So, what was happening in Maeno house? The relative of Maeno family, friends, neighbors, and tourists and so on were always gathering in the house and chattering all night long. They talked about every battle in detail with gesture. The stories were some times fanny, some times sad and hard. Katsukane, the son of Maeno family was always listening to the stories and decided to record those for the future.
