Teuchi

is a citizen of Konohagakure and the owner of Ramen Ichiraku.

Personality
Teuchi is a very kind and jovial man. Often seen smiling, he and his daughter, Ayame, have always treated Naruto Uzumaki well, considering him their best customer. Nevertheless, he is a stern businessman and will lash out at his employees when they make mistakes such as sticking their thumb in a bowl of ramen. He has also been described as sturbborn, obstinate, and having the temperment of a craftsman.

After Naruto managed to cut the waterfall in his wind natured chakra training, he was treated to some ramen at Ichiraku. However Teuchi kept rejecting the ramen made by his apprentices Matsu and Nishi before Naruto could eat it, and was quickly getting angry with them, claiming that they kept making these stupid mistakes.

In the anime, Teuchi is seen working behind the bar with his daughter, Ayame, while Naruto and Jiraiya discuss about dealing with Itachi and Sasuke.

Confining the Jinchūriki Arc
Soon after Tsunade regained consciousness, Sakura burst into Ichiraku to inform Naruto and Teuchi about what happened. Upon hearing the good news, Teuchi offered a bowl of ramen to both Naruto and Sakura, on the house, which Naruto accepted, but Sakura declined. Just as Naruto was about to eat he was reverse-summoned to Mount Myōboku, much to Teuchi's confusion. When Naruto reappeared in Ramen Ichiraku, Teuchi asked where his best customer disappeared to. When Naruto was asked by the other ninja customers for his autograph, Teuchi thought proudly at how Naruto was being called the "Miracle boy" and at the irony at how not so long ago he was thought of as the opposite. Teuchi then asked the other customers to allow Naruto to finish his meal before he signed anything.
