Umi is a character in Ōkami. He runs a segregated restaurant in North Ryoshima Coast. After bringing the Fisherman the Marlin Rod and helping him catching the Marlin, he delivers it to Umi, who uses his "Cyclone Slice" to make some sashimi. Amaterasu must use the Celestial Brush to draw three horizontal lines and learn the secret Celestial Brush technique of Galestorm, Whirlwind. Amaterasu can then eat the sashimi that Umi has prepared to fill her Astral Pouch.
Umi is a man of his 30-40's. He has a cat-like motif, like Yama, in which his face does looks like a cat. His eyes are feline-like, his nose is triangle-shaped, and on each of his cheek are 3 stripes which resemble a cat's whiskers.
Umi wears a typical grey tall cap, a sea blue colored happi which has the embroidering of a darker blue wave on it. On his shoulders, there are some red straps which helps in folding his sleeves to his shoulders. On his apron, the kanji for "sea" (「海」?; umi) is present, also spelling his name. Also, he is always seen holding a pair of kitchen knives.
- Umi and his restaurant, along with Yama and his cafe, are based on the Japanese story of Chūmon no Ōi Ryōriten (「注文の多い料理店」?; The Restaurant of Many Orders).
- "Umi" (「海」?) means "sea", which, aside from being his name, is also a reference to where his restaurant is located.
- Both Umi and Yama have a cat motif, along with their waitresses. No other people in the Ōkami series have such features.
- Umi is the counterpart of Yama, since his restaurant is by the sea, while Yama's restaurant is in Sei'an City. Their name also relates with their locations respectively.
