[5][6] On January 21, 2022, Hikawa announced through his firm's website that he would temporarily suspend his singer activities from December 31, 2022.

Hikawa usually dresses in trendy casual clothes, sometimes appearing in the more traditional kimono normally worn by Enka singers.

Since 2019, Hikawa has begun dressing in both masculine and feminine fashion on-stage and off, coming out as "genderless" in 2020.

[8] That same year, he made history by performing on Kōhaku without being assigned to either the Red (female) or White (male) team.

In 2003, he was the guest of honor at Hawaii's week-long Aloha Festival, where he participated in a parade with various Japan-based hula halau, and ended the week with a concert.
