Early life Higashi was born in Kanazawa, Ishikawa Prefecture. After enrolling in Hokuriku Gakuin Junior and Senior High School Later on she, with seven other members including Sumika Nono, joined Hanagumi, she became a staff member of the teenager events "Onna no Ko" ga Sukina "Onna no Ko" no tame no Tomodachi-zukuri Event and Peer Friends for girls until July 2014. In January 2014, Higashi wrote the manga Lesbian-teki Kekkon Seikatsu (co-written with her wife Hiroko Masuhara, and illustrated by Emiko Sugiyama), later in June she wrote Nakatta koto ni shitakunai – Jippu kara Sei Gyakutai o Uketa Watashi no Kokuhaku ("I do not want to make it not – I confessed my sexual abuse from my father") by herself, in which she started writing in earnest.

In addition, she presented in Makimū & Koyutan no Lesbian Channel in Niconico's live broadcast with lesbian tarento Asako Makimura, Higashi also presented Koyutan no Suiyōbi in which it broadcasts on the theme of LGBT enlightenment and events related to the LGBT community.

Her same-sex wedding at Tokyo Disney Resort In March 2012, Tokyo Disney Resort announced the plan "Disney Royal Dream Wedding" in which the Cinderella Castle opens wedding ceremonies for ordinary guests in the park. Upon this, Higashi contacted the resort to have a same-sex wedding, although the use of same-sex was said to be satisfactory, due to the "influence on ordinary customers", they answered that either one had to wear a tuxedo (the men's costume). When it was sent in Twitter, the critical response to Disney's response has expanded. Later on 1 March 2013, Higashi cited the ceremony at Tokyo DisneySea, and became the first couple who made the same-sex wedding ceremony at Disney Resort in Japan.

"Partnership Certificate" in Shibuya Tokyo's Shibuya Ward is the first Japanese municipality that decided to issue "partnership certificates" to same-sex couples, after its assembly voted in favour of an ordinance containing this policy on 31 March 2015. Applications for these certificates started on 28 October of the same year. Higashi and her partner applied for the certificate and on 5 November they became the first couple to receive such a certificate from a Japanese municipality. While the policy of LGBT partnership systems has been spreading across Japan and hundreds of other couples have followed in Higashi's footsteps, she and her partner have since split up and returned their partnership certificate to Shibuya Ward.
