Please look at the photos carefully before purchasing to avoid any misunderstandings such as "it's different from what I expected" after purchase. #Toyozo Arakawa #Azuchi #Gifu Prefecture #Azuchi-Momoyama #Oda Nobunaga #Shino Soshin #Mino #Nezu Shino (Gray Shino) #E-Shino (Painted Shino) #Shino Oribe #Aka Shino (Red Shino) #Neriage Shino (Marbled Shino) #Teacup #Matcha #Tea #Tea Ceremony #Cafe #Antique #Antique #Iron Glaze #Snow #Artist's Work #Yunomi (Teacup) #Yunomi (Teacup) #Sencha (Green Tea)
