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?
