Given its proximity to Edo, the Hakone checkpoint was particularly known for its strictness, checking for arms coming in and women (hostages) going out—predominantly the latter. Very strict female officials specializing in spotting feminine features, called hitomi-onna (人見女, literally "person-viewing women"), would inspect any female travelers, with a particular eye out for women disguised as men. Racks of weapons were prominently displayed to intimidate those passing through.
