This is the third major single by singer-songwriter aiko, which is said to have been born from her feelings about missing a fireworks festival due to her busy schedule.

The song was used in a Circle K commercial for “Hiyashi Chuka/Refreshing Summer Ramen” and as the ending theme for the debate variety show “Geki Maji!! ~Teen no Honne~,” and it’s also known as one of aiko’s signature tracks.

Its lively shuffle beat and hooky melody are catchy yet evoke the depth of a summer night sky.

aiko - “More” music video

On cold winter days, we sometimes find ourselves longing for someone’s kindness and warmth.

The song I’d like you to listen to is “Motto,” released by aiko in 2016.

Its lyrics, which depict the changing of the seasons, mirror the growing emotional distance between lovers.

Even the repeated phrase at the end of the chorus conveys a straightforward affection toward an ex-partner.

Set to a jazzy piano sound, her emotional vocals unfold throughout the track.

Why not listen while thinking of that unforgettable, special person?

aiko Love Road

A masterful song by aiko that captures both the ache and warmth of a long-distance relationship.

Included on the album “Himitsu,” this track delicately portrays the feelings of two people in love despite the distance.

From the opening lines, you can sense the awkwardness and anxiety of their reunion.

Yet it also highlights the importance of communication, singing that “the two of us still have words.” Released on the April 2008 album and performed on her 2011 live tour, it’s a highly recommended song not only for those in long-distance relationships but for anyone who wants to feel the bond with someone special.
