Togen Shirataki (桃源白滝,Tōgen Shirataki?, literally meaning "Paradise White Waterfall"): Oden hardens both his swords using Ryuo and then delivers a diagonal slash with each one of them at the same time. This technique has immense power and range, as seen when Oden used the technique to bisect the massive Mountain God.Shirataki is a type of Japanese noodles and a popular ingredient in oden, which follows the oden-themed naming scheme of Oden's techniques. In the VIZ Media translation, this is called Paradise Waterfall.
Gun Modoki (銃・擬鬼,Gan Modoki?, literally meaning "Gun Imitating Demon"): After hardening his swords using Ryuo, Oden crosses his swords and charges forward, slicing anyone in his path. When Oden used this technique, he was able to defeat several members of the Roger Pirates at once. The attack name is a pun on ganmodoki, Japanese fried tofu fritter made with vegetables and a popular side for oden, in keeping with the naming scheme of Oden's techniques. In the VIZ Media translation, this is called Gun Modoki.
Togen Totsuka (桃源十拳,Tōgen Totsuka?, literally meaning "Paradise Ten Hands"): Oden hardens his swords using Ryuo, then leaps toward his opponent, and performs an X-shaped slash powerful enough to give the nigh-invincible Kaido his permanent scar. "Totsuka" is a reference to the four Totsuka-no-Tsurugi mentioned in Japanese mythology, one of them being Ame no Habakiri. In the VIZ Media translation, this is called Paradise Totsuka.
Togen Totsuka (桃源十拳,Tōgen Totsuka?, literally meaning "Paradise Ten Hands"): One of Kozuki Oden's signature techniques performed by Ashura Doji, Kin'emon, Denjiro, and Inuarashi. Together they are all able to simultaneously slash the same X-shaped scar given to Kaido by Oden 20 years ago drawing copious amount of blood. Though, Kaido stated it is significantly less powerful compared to Oden's usage as he stated the damage they inflicted is trivial in comparison to Oden who had successfully inflicted a massive scar on him.
According to Wano Country's propaganda, Kurozumi Orochi claimed to have used the Orochi Nitoryu (オロチ二刀流,Orochi Nitōryū?, literally meaning "Orochi Two Swords Style"), to defeat Oden and his retainers. In reality, Orochi never even participated in said battle, and he showed very poor swordsmanship.
