Yamato (ヤマト, Yamato) is a minor character in the Sekai-Ichi Hatsukoi series. He is the nephew/adopted son of Kanade Mino.
Yamato has short dark hair and dark eyes. The colors of his eyes and hair have not yet been decided.
Yamato acts brash and whiny, but is only trying to get his adoptive dad's attention. He feels lonely and wishes to spend more time with Mino.
In the manga, Yamato throws a fit in public because he has trouble telling Mino that he feels lonely. When Mino is offered a trip to an onsen by the company, Yamato comes along as well, hoping to spend more time with him, but ends up arguing with Mino about not understanding his feelings instead, and runs off. Ritsu Onodera ends up finding him in the woods and is able to talk with him. He gets Yamato to confess to Mino about how he really feels and wants. Mino then promises to spend more time with Yamato and pay more attention to him.
