Ikarashi Momoko (五十嵐 桃子) is a prominent Japanese contemporary glass artist celebrated for her delicate, ethereal works that capture light and atmosphere.

Ikarashi works primarily in kiln-cast glass, a technique that affords her precise control over texture and opacity. Her practice is rooted in sensory experience — the quality of light, the weight of humidity in the air, the quiet emotion of standing before a landscape at a particular moment in time.

Her pieces are characteristically translucent with soft, matte finishes, conceived as vessels that "seal away" a fleeting feeling or memory. Muted gradients, subtle surface textures, and a quiet luminosity evoke the appearance of mist, ice, or light diffused through overcast skies.
