Nathan Adams (Japanese: 天野 景太 Amano Kēta), often referred to as Nate (Japanese: ケータ Kēta), is one of the main characters in the Yo-kai Watch series. He appears in almost all Yo-kai Watch-depicted media, as he is the playable character of the main series video games and the main character in the Yo-kai Watch anime series.

He is an only child who possesses an item called a Yo-kai Watch, which allows him to see, befriend and summon Yo-kai. Nate also despises being called "average", and so goes to great lengths to be better and even impress Katie Forester.
