MIREI is the alluring and dauntless voice from Japan using modern pop bangers to call attention to what you may have never known if you were not living in Tokyo.

In Japan, MIREI is known as Touyama Mirei (當山みれい), and has been a prominent figure in the music industry, releasing a series of chart-topping hits through Sony Music since 2014. Her Japanese-language tracks have garnered more than 330 million streams domestically and an impressive 730 million streams worldwide, giving her the title of “songstress of streaming”. After great anticipation, “Lonely In Tokyo”, the smash hit from her International debut album, Take Me Away is finally available to fans in Japan after a three year wait since its original release. The new EP includes a Japanese version of the track and a new Phonk House Remix featuring BENXNI of STARKIDS, Tokyo’s hottest underground squad that’s famous for its cutting edge sound.

“Lonely In Tokyo” spotlights the dark realities of the Japanese idol industry, with it luring innocent dreams and aspirations whilst creating lost, lonely souls. MIREI first began writing the songs in English 5 years ago, and recorded the tracks with friends in Brooklyn, NY as a way to explore more potentials for her voice and expand from her artist career. After its release (excluding Japan), countless listeners resonated with her view and experience of loneliness and isolation, garnering her a strong, dedicated fanbase all over the world. “Since I released Lonely In Tokyo at the beginning of 2020, the world has changed so drastically,” MIREI explains, “The more we got cut off, the bigger the gaps between people and loneliness got. Money, body, fame, love… in every city, every generation, in every language, we’re all living, striving for our future and dreams alone. This is what I see in my city right now; it’s definitely “Lonely In Tokyo” at Tokyo,” describing the updated views in her new Japanese version. The track helps listeners of all ages feel more at comfort at their loneliness and struggle with human interaction by realizing they are not actually ‘alone’, as MIREI gives them inspiration and courage to face solitude and yourself.

About Yameii Online

Together, Atlanta-based visual artist Oseanworld and music producer Deko created Yameii, a virtual character with her own personality and music career.

Yameii was initially conceptualized as the hero in the OSEANWORLD anime, available to watch on YouTube. Osean intended for her to be a singer, but once he and Deko teamed up, her music evolved and took on a more rap-influenced form. Inspired by Japanese vocaloid characters such as Hatsune Miku and the duo’s Atlanta roots, they developed and refined her iconic hyper-pop sound, blending pop, electronic sounds, and rap in a way that appeals to both a Western and Eastern audience. The duo have since worked together on building Yameii’s brand across music, visuals, & merchandising.
