In 2020, with the goal of “reaching the world from Japan,” she began writing songs using English and guitar skills she taught herself. With the release of her 2024 single, her younger sister, “TOKIDOKI KURUMI,” joined as a co-producer, and they began producing alternative/pop-rock tracks. She has already received numerous collaboration offers from both Japan and abroad. Tiara’s greatest asset—her unique, husky, yet clear and powerful voice—has earned her high acclaim as a singer, and the total number of streams for the tracks she has contributed to has surpassed 20 million and continues to rise. Destiny Hope Tiara is a “slightly unconventional artist” unlike any other. Yet, it is precisely for this reason that she shines as the “Diva of Hope Who Forges Her Own Destiny.”
