A Japanese scroll art created 200 years ago during the Edo period (1603-1868) is dedicated to gas warfare, but not the kind of gas traditionally used in combat.

The He-Gassen (literally “Fart Battle”) portrays multiple scenes where individuals direct their flatulence against their adversaries. Art historians believe the work was inspired by growing suspicion of foreign influence during that period.

Inasmuch as “kamikaze” literally means “divine wind,” one can’t help but note the fact that wind — divine or otherwise — has a long history of being used against foreign opposition.
