Zinee&issei, a talented mixed male-female unit, has released a long-awaited new song "TAKARAMONO" after an absence of about a year. The new song "TAKARAMONO" was conceived based on Zinee&issei's own experience of adopting a shelter dog, and was written as part of their love for pets and their lifework of animal welfare. The song is a reflection of Zinee&issei's deep love for their beloved dogs, who have become their family and "treasures," and is wrapped in the straightforward words and exquisite harmonies that are typical of Zinee&issei. The chorus is performed by Yoichi Kitayama of the Gospellers, one of Japan's leading vocal groups. The vocal work of Zinee&issei mixed with Yoichi Kitayama's chorus creates an exquisite ballad. Produced by MANABOON, who has provided keyboard support and song production for numerous artists. The song was mixed by Shinichiro Murayama, who has worked on hit songs for many R&B artists. A portion of the proceeds from the song will be donated to animal welfare and protection organizations.
