After graduating from Tokyo Bunka Fashion College, Tsuyumi exercised a flair for controlled exuberance while designing costumes for the acclaimed performance troupe Zinjanthropusboisei as well as outfits for drag queen performers. She is the recipient of the gold medal in the 13th Annual Lumine Fashion Design Prize for her line that presented a merging of skirts and shirts as on metaphor.

She started her hats collection from Fall/Winter 2004.

Her new line under her own name brings all of her experiences together creating accessories that embody a thoroughly modern take on femininity - whimsical yet playful- dramatic yet personal.
