Wani (鰐) is a dragon or sea monster in Japanese mythology.
Since it is written the kanji 鰐 (from Chinese e 鰐 or 鱷 "crocodile; alligator") wani is translated as "crocodile", or sometimes "shark" (from wanizame 鰐鮫 "shark"). However, it is used several times as a proper name in The Kojiki (e.g., the Confucianist scholar Wani, Chamberlain 1919:2,313) and once as a sea-monster,
The ya-hiro no kuma-wani (八尋熊鰐 lit. fathom bear wani
The sea-god Kotoshiro-nushi-no-kami (see Ebisu) and sea-princess Tamagushi had a daughter who married Emperor Jimmu, the legendary first emperor of Japan. Another version is that Koto-shiro-nushi no Kami, having become transformed into an eight-fathom bear-sea-monster, had intercourse with Mizo-kuhi hime of the island of Mishima (some call her Tama-kushi-hime), and had by her a child named Hime-tatara I-suzu-hime no Mikoto, who became the Empress of Emperor Kami-Yamato Ihare-biko Hohodemi.
