The Omi Alliance is one of the biggest yakuza groups in the Yakuza series. With their main base of operations in Sotenbori, they often find themselves at odds with the Tojo Clan in Kamurocho. They’re equal in power, and in many of the games are at the brink of war with one another.
The Omi Alliance is filled with strong members, many times rivaling the power of those in the Tojo Clan, sometimes being even stronger. They tend to be more scheming than their Tojo Clan counterparts. The Omi Alliance is a large crime organization and has had a constant presence throughout the games.
