Tasogare 黄昏 (Twilight)
There is a moment, just before the sun disappears, when the world softens. The sky, awash in hues of burnished orange and pastel purple, holds its breath. Tasogare, meaning "Twilight," captures this fleeting beauty in a bottle.
The fragrance opens with a radiant burst of mandarin, cassis, and bergamot -- bright, juicy, and full of life, like the last rays of sun warming the horizon. The heart of the fragrance blooms with orange blossom, lavender, and jasmine, creating a delicate floral veil that mirrors the sky's gentle fade into dusk.
As the light slips away, the base reveals its quiet depth: earthy vetiver, creamy tonka bean, and smooth cedar melt into a whisper of transparent ambergris, leaving behind a scent that lingers like the warmth of twilight on the skin.
Presented in a bottle that mirrors the sunset itself -- a soft orange and purple hued gradient glass is finished with the golden rays of the sunset from the metallic gold magnetic cap.
Tasogare is a tribute to stillness, serenity, and the beauty found in the in-between.

Fragrance Notes
Our Perfumer
Yusuke Masuda
Yusuke Masuda is originally from Mishima City in Shizuoka Prefecture, Japan, where he grew up at the foot of Mount Fuji. He got into perfumery because he felt a deep connection with the spirit of Japanese craftsmanship — the pursuit of precision, sensitivity, and beauty in every detail.
Yusuke’s artistic style as a perfumer could be described as a balance between quiet elegance and emotional clarity. He is drawn to compositions that feel refined yet expressive, with a transparent structure that allows each material to breathe.
増田湧介は、日本の静岡県三島市出身で、富士山の麓で育ちました。
彼が調香の道に進んだのは、日本の職人精神――細部へのこだわり、繊細さ、そして美しさを追求する姿勢――に深く通じるものを感じたからでした。
調香師としての湧介の作風は、「静かなエレガンス」と「感情の透明度」が調和したスタイルと言えるでしょう。素材ひとつひとつが呼吸する余白を大切にしながら、洗練されつつも豊かな表情を持つ香りを追求しています。
