Narumi

What Narumi does

Narumi Corporation is a Japanese ceramics manufacturer founded in 1946 and headquartered in Nagoya, Aichi Prefecture. The company operates two principal business segments: a Tableware Business producing premium bone china for luxury hospitality (five-star hotels, Michelin-starred restaurants, airlines) and consumer retail, and an Industrial Materials Business producing super heat-resistant crystallized glass used in IH cooking heater top plates, gas stove front glass, and furnace wall materials. Narumi became Japan's first mass producer of bone china in 1965 following a proprietary raw-material patent, and its bone china formulations exceed JIS standards with over 40% calcium phosphate content (versus the 30% JIS minimum). The company also operates an OEM/custom manufacturing service spanning bone china, porcelain, alumina-reinforced porcelain, and optical glass products.

Revenue is generated through four streams: one-time sale of bone china and porcelain tableware (its dominant line, including the heritage Milano collection with 14+ million pieces sold since 1972), industrial hardware sales of heat-resistant crystallized glass components to appliance OEMs, custom OEM manufacturing services, and licensing royalties on proprietary designs. The go-to-market combines enterprise field sales through dedicated HORECA divisions in Japan (Sendai, Tokyo, Osaka, Fukuoka) and overseas offices (Singapore, Shanghai, Hong Kong, Torrance USA, Jakarta), a global authorized dealer network spanning five continents, direct-to-consumer e-commerce (e-NARUMI), a factory shop at the Mie plant, and department store counters (Isetan, Mitsukoshi, Takashimaya among others). Named enterprise customers include Four Seasons, Capella, Mandarin Oriental Hyde Park London, Fairmont, JW Marriott, ANA, and Qatar Airways. Manufacturing is split between the Mie Narumi mother factory in Japan and P.T. Narumi Indonesia (two plants since 2010).

Narumi is a privately held subsidiary of the Ishizuka Glass Group (株主 since 2015), with 540 million JPY registered capital and approximately 260 employees. The company has accumulated a track record of design recognition including multiple Red Dot, iF, Good Design, and Tableware International Awards of Excellence wins, and in 2026 received the Sustainability top award from Tableware International for its eggshell upcycling material.
