Osaji

OSAJI is a Japanese skincare lifestyle brand founded in 2017 by Masakazu Shigeta. Its roots reach back to Nitto Denka Kogyo’s healthcare division, which began selling basic cosmetics in 2004 and received a cosmetics manufacturing-sales license in 2005; Shigeta had entered cosmetics development in 2001 after working in music and studied dermatological science with a focus on sensitive skin. The name refers to an Edo-period term for physicians who compounded medicines with a spoon, while OSAJI’s approach combines skin science with a holistic view linking skincare to emotional well-being and sensory experience. In 2019, the brand added makeup and the KAI anti-aging-care line, with beauty writer AYANA directing seasonal makeup collections and Shigeta handling safety and scientific formulation priorities. OSAJI entered fragrance in autumn 2020, exploring memories, emotions, and familiar Japanese scenes, followed by gender-neutral woody scents in spring 2021. It opened the kako home-fragrance blending shop in Tokyo in 2021 and launched its first eau de parfum collection in 2023, built around Japanese wild rose. In November 2023, the business was transferred to OSAJI Inc., which entered a capital and business alliance with Marubeni and Gunma Regional Co-Creation Partners.
