Welcome Horizons

"Welcome Horizons" is a K.K. Slider song that debuted in, though it was first performed live during the Splatoon concerts at the Nintendo Live 2019 event in Kyoto. It is the only original K.K. Slider song to be added in.

"Welcome Horizons" is, in fact, a rendition of the title theme for. It can first be heard in-game playing from a tape deck outside of Resident Services during the bonfire party to celebrate the first night living on the island. Tom Nook will give the resident representative an aircheck after K.K. visits the island and performs for the first time. Other players on the island will receive it directly from K.K. Slider himself, who will always play the song upon attending his show for the first time. The song can also be heard in, on the Portable Radio furniture item from the Island Excursion Invite Set.

The track features heavy usage of brass instruments, ukulele, and maracas, with bongos and accordions also present, along with a tambourine being shaken, giving off a tropical vibe.
