About Me

東京在住の、日本人プラスサイズモデル。

山梨県出身。幼少期の6年間を米国で過ごし、日英のバイリンガル。


物心のついた頃から「太い」が自分のアイデンティティの大部分を占め、

20代半ばまで自尊心にも大きく影響。

ボディポジティブに出会い自分を解放し、初めて「ありのままの自分」に

なれた経験から「ありのままの自分を愛するボディポジティブ」ではなく「ありのままの自分になれるボディポジティブ」をテーマとし、

2018年秋からプラスサイズモデルとして活動開始。


日本におけるボディポジティブのロールモデルを目指し、国内外の

インフルエンサーとのコラボのみならず、ジェンダー平等に取り組む団体のイベントで登壇するなど、ボティポジティブやセルフラブ(自己愛)、「Health at Every Size」の啓蒙・啓発にも力を入れている。


2023年にはNYFWやLAFW会期中のファッションショーにも出演し、

米国のファッションウィーク会期中に現地のランウェイに出演した、

初の日本人プラスサイズモデル」となる(※)。


2024年4月より、フリーランスのモデルとして新たな道を歩み始めた。


モデル業以外にも、広報コンサルティング、翻訳、英会話講師、

バイリンガルMCなどの仕事もしている。

Growing up being fat-shamed especially by her family, being fat was a major part of her identity until her mid-20s, severely affecting her self-esteem.

It was only after she met body positivity that she was able to become her true self; based on this experience, she started her career as a plussize model in 2018 under the motto, “Body Positivity: Become Your True Self” instead of the usual Japanese message of “Body Positivity: Love Yourself as You Are.”


She is also active in not only collaborations with influencers in both Japan and overseas, but also speaking engagements to bring awareness and enlightenment about body positivity and self-love in Japan, such as by being a guest speaker for events hosted by organizations pursuing gender equality.


In 2023, Mariana walked for numerous fashion shows during New York and Los Angeles Fashion Weeks, making her “the first Japanese fashion plus-size model to walk in the USA during Fashion Week season,” according to research done by the boutique online fashion magazine, Fashion On The Beat.


Mariana started a new chapter of her modeling career as a freelance model from April 2024, making her available for more opportunities in Japan and overseas.


Mariana LYS is currently based in Tokyo, Japan. She is originally from Yamanashi Prefecture, Japan but also spent 6 years of her childhood in the US (1 year in Utah, 5 years in Pennsylvania). Thanks to this experience, she is fully bilingual in Japanese and English.


Aside from modeling, she also continues her career in public relations consulting, translation, English tutoring, and bilingual moderator for events.
