A ballad song by the collaboration of Nami Nakagawa singing "Kamado Tanjirou no uta" of the Kimetsu No Yaiba (Daemon Slayer) awarded to the Japan Record Award and Moeko Nakamura acting in various musical performance such as Les Miserables. Two artists featured together through SNS despite restrictions due to Covid-19 epidemic. Thereafter, a song of collaboration is born loving the songs and voices of each other even though the two have never met before. The song name "Hakobune" is a ship bringing the hopes, lights toward the exit of the covid crisis in the world. Lyric is made by Goro Matsui and the music is made by Masayuki Iwata, both of who are the long-running artists of the J-POP. A magnificent and beautiful music is born here.
