He went to the same cooking academy as Teuchi. Many years after attending the academy, Hakkaku had become a succesful cooking-nin.

He visited Teuchi and wanted to know the recipe only to be denied. In an attmept to know the recipe, Hakkaku and his fellow cooking-nin kidnapped Teuchi's daughter Ayame to get the "Phantom" recipe and left a note and a picture of Ayame tied up to Teuchi, saying that he'll let Ayame go in exchange of the recipe.

On the day of the deadline, he and the three ninja met up at the area where they were to meet up with Teuchi. Hakkaku's concealed ninja prevented Teuchi from advancing to where Ayame's voice was heard from, with Hakkaku stating that he will see his daughter once the contest is done. Teuchi, with the help of Naruto Uzumaki, Chōji Akimichi, and Sakura Haruno, had to compete against Hakkaku's cooks in a contest to see who can make the best Ramen. The three genin eventually aided Teuchi in crafting the perfect bowl of ramen. In reality, the "Phantom" recipe didn't exist. It was just the disposal of the broth's bitter taste. As a result, Hakkaku let Ayame go, who had gotten fat from Hakkaku's food, much to Teuchi's dismay.
