The only difference with this one as opposed to the other "entries" - is this one has 2 girls committing suicide, and they are outdoors and wearing samurai style outfits as opposed to Japanese robes or some other "costume". Also, they stab themselves with samurai swords instead of the typical shorter ritual knives...

A girl in a traditional Japanese robe. who exposes her breasts, caresses her midsection for a while, then stabs herself in the stomach and slowly pulls the ritual knife across her abdomen.
