Ipponume is a tall stout woman with short reddish curly hair. Before the time jump, she wears a purple cap and a yellowish striped shirt.
When Zoro stopped by Tanne’s weapon store in Loguetown, Tanne refused to sell Zoro the third generation Kitetsu because it was cursed. Ipponume, on the other hand, urged her husband to finally sell the cursed sword. After Zoro daringly threw the sword in the air, which missed his arm, Tanne gave him the sword for free. Tanne also gave him his family heirloom, the Yubashili, which did not please his wife at all.
Two years later, Tanne hung a large picture of Zoro in her bathroom. Ipponume seemed less than thrilled about it.
