Is Hyouge Mono historically accurate? The anime and manga, Hyouge Mono, is set in the Sengoku era and follows tea related items. I can see that in general the events of the era seem to be more or less accurate, and all the wacky outfits probably aren't accurate (or are they?), but I'm wondering about the tea related aspect of the series. 

Did the warlords of the time (especially Oda Nobunaga) have tea masters and treasure master crafted tea-ware in any way like they're portrayed in Hyouge Mono? Are any of the crafted items, at least the ones with proper names, real items from the period?
All characters on the show are based on historical figures. Furuta Sasuke is in fact Furuta Oribe but he will only change his name later in life.
Same goes for Sen no Soeki who will become famous under the name of Sen no Rikyu.
