In episode 765.
The House of Sakurada (桜田家 Sakurada-ka) is where Nene Sakurada lives with her mother and father. It first appeared in episode 18b.
It has the typical structure of the rest of Japanese houses that are seen in the series: two floors, a garden and a garage.
When the boys visit Nene, they usually stay in the living room, where they play, snack, etc. The most characteristic room in this house is a dark and small, where Nene's mother hides her giant stuffed rabbit, which she hits when Shinnosuke makes her nervous.
