Sekigahara...400 years ago?!?Isn't it the Edo period or the engoku Jidai if you are talking much earlier?Sekigahara is no doubt the battlefield where Tokugawa acclaimed victory from Ishida Mitsunari(although in name the lord is Toyotomi Hideyori,but the one dictating everything is Ishida,so Hideyori is like a puppet emperor) but did they name an era after it?i am confused myself...
