Japanese solo artists <a href="/music/Ayaka">Ayaka</a> and <a href="/music/Daichi-Miura">Daichi Miura</a> have joined forces with producer Takeshi Kobayashi to create a killer duet called "Heart Up" to be released on Valentine's Day 2018.
Ayaka, a singer-songwriter, and Miura, a vocal and dance performer, began their careers around the same time and both turned 30 this year. They make different types of music but have both been at the forefront of their respective fields ever since their debuts, and they welcomed the opportunity to collaborate on a new single.
The project initially started in April as a new tie-up song for a major TV commercial. Ayaka, Miura and Kobayashi first got together in the summer to discuss the new single, and Ayaka wrote a love song with Miura's vocals in mind.
