Watanabe’s wife was not to trifle with
“Watanabe’s wife with a child on her back and two severed heads at her feet” from Taiso Yoshitoshi’s Biographies of Valiant Drunken Tigers (1874).
The weapon in her capable hands is a naginata.
More Japanese woodblock art here.
And female use of the naginata here
Further, do not pick a fight with a wife of Watanabe.
