Ask for the name of a Japanese cartoon, about Toyotomi Hideyoshi.

I haven't read the cartoon you said, but the prototype is probably ODA tea. Her mother, Ota City, was called the first beauty in the Warring States Period. Tea finally gave birth to Xiuji, and it is the future Toyotomi Hideyori. Only the later Edo shogunate always called tea a slut. Look for it along this line.
