Mooncastle is a Japanese knitwear factory brand founded in 2020 by a historic manufacturer established in 1966 in Misaki, Osaka Prefecture. Nearly all garments are produced in the brand’s own in-house factory, ensuring full control over quality, materials, and craftsmanship at every stage of production.

Guided by the philosophy of the “finest basic,” Mooncastle creates timeless, everyday knitwear using premium natural materials such as cashmere, wool, silk, and rare kid mohair. Designed to be worn often and to age beautifully, each piece balances refined simplicity, exceptional comfort, and long-term value.
