### 2011–2021: Transfer to Universal

Crystal Kay's Spin the Music tour was planned to have nine shows across Japan starting February 5 and ending March 29, 2011. Her tour was cancelled after she went to the hospital complaining of sickness and was diagnosed with Acute Nephritis. Crystal Kay was advised not to go on with the tour in order to rest and recover from her illness. Her record label offered refunds through the tour's website. Crystal Kay later performed at the August 2011 MTV Zushi Fes music festival. On April 29, Crystal Kay held a Q&A on her blog and answered her fans' questions, with one question regarding a possible Korean debut. Considering her mother is of Korean ancestry, she has stated: "I can speak just a teeny bit of Korean (lol). My reading and writing are perfect, but learning vocabulary is sooo hard! It's no good that I don't do listening or speaking. I'll think about a Korean debut! I'd like to be able to sing in Korean." On October 5, Universal Music Group subsidiary label Delicious Deli Records posted an announcement that after twelve years Crystal Kay had left Sony Music Japan and signed to them.
In 2012, Crystal Kay recorded a cover of "Eyes on Me" for the "FINAL FANTASY Orchestra Album", becoming the latest in a series of notable artists to cover the song, including Angela Aki, MayBee and Kanon.
In 2013, the singer participated in DANCE EARTH PARTY's debut single "Inochi no Rhythm", part of DANCE EARTH's project DANCE EARTH ~Seimei no Kodo~. In March of the same year, she moved to New York, United States, in order to start her international career.
On February 14, 2014, she officially released her US debut music video via MTV Iggy, "Busy Doing Nothing". On July 1, she celebrated her 15th debut anniversary. In November of the same year, the singer announced that she moved her management to LDH.
In January 2015, the singer returned to Japan after a final acoustic concert in New York. Looking back at the time she lived in the United States, she described the experience as a turning point in her life: "It was the first time I lived alone in New York and the first time I lived abroad. I went there because I wanted to try my hand at music, and although it didn't lead to my debut in the end, I think I learned a lot there and was able to plant some seeds. Anyway, it was a journey to face myself and become stronger. Going to New York was the first time I was able to face my identity crisis, which I had been dealing with since I was a child. I think it was a good thing that I was able to think, 'I should have more confidence in my identity'. The other thing is that people in their late twenties have unique problems. Especially for women, it's the age when they have to worry about work, marriage, and childbirth." In terms of music, she succeeded in refining her skills despite not being able to make her international debut: "My goal was to get a record deal there, but I thought it would be better to actually live there, join the local community, and get to know the producers, so I decided to take the plunge. But it was difficult because I didn't have any connections. I went into the studio every day and wrote over 60 songs, but I was an unknown singer over there. For two years, I went back and forth to Japan, meeting with producers, doing sessions, voice training, dancing, and so on." Besides working on her musical career, she also went to acting classes and took an "overcoming anthropophobia course" in New York. On June 3, she released her first single under LDH's management and 30th single overall, "Kimi ga Ita Kara", being also her first single after three years since the release of "Forever".

## Influence

Crystal Kay is considered a pioneer for interracial acts in Japan and across the world. She debuted in 1999 when R&B began to take off in Japan thanks to local acts MISIA, Double and Hikaru Utada. Her success paved the way for many mixed-race artists such as Thelma Aoyama, R&B singer AISHA, Emi Maria, Miss Universe Japan Aisha Harumi Tochigi, Saarah of J-pop group BananaLemon, and enka singer Jero. Crystal Kay has also been cited as inspiration to artists outside of Japan like Joyce Wrice and UMI (singer).

## Personal life

In 2009, Crystal Kay said, "There is still some racial thing going on, [but] people are getting used to it. You can see a lot more mixed people on TV, and even (among) models in magazines." At a summer festival that year, the half-Japanese half-Papua New Guinean singer Emi Maria left Crystal Kay a demo and a note saying, "You're my idol, I'm sad I couldn't meet you in person." Nevertheless, Crystal Kay has said, "I consider myself a Japanese artist because I was born and raised here, but nationality-wise I look, and am, foreign."
In her life, Crystal Kay had been struggling with her identity and didn't want to stand out: "I was born and raised in Japan, but I don't have any Japanese blood in my veins (my father is American and my mother is Korean), so I had always had a complex.", "There was only one senior I knew who was Korean and Black [...]. They (the others) were all Black and Japanese, or white and Japanese, or half-Japanese. [...] I thought of myself as a minority among the majority." However, living in New York between 2013 and 2015 helped her accept her multi-ethnical identity: "I had this complex that made me shrink back. But when I talked about it in New York, people would say, 'What are you talking about? You're carrying three cultures on your shoulders, and you're building a good career in Japan, isn't that great? You should be more proud of yourself.' I thought, 'That's right'." As for her future, she dreams of becoming a "bridge between countries": "It could be through music, a musical, or a movie. I'm also very interested in acting, so I want to be a bridge through entertainment in any genre."
