- Choushimaru Co., Ltd. (3075.T) operates a chain of gourmet conveyor belt sushi restaurants primarily under the Sushi Choushimaru brand in Japan, offering authentic Edomae-style sushi prepared fresh in-store with seasonal seafood such as tuna, shrimp, salmon roe, scallop, mackerel and cuttlefish sourced from markets including Toyosu and Choshi Port; the company utilizes proprietary blended vinegar from sake lees and rice aged with traditional red vinegar, hand-crafted rice balls served at body temperature to enhance flavors, and house-made soy sauce with rich dashi notes, alongside other chains including Edomae-Sushi Hyakumangoku, Sushi Choushimaru Miyabi and Sushi Yasuke totaling approximately 88 locations concentrated in Tokyo Metropolis, Saitama, Chiba and Kanagawa prefectures. Founded in 1977 and headquartered at 2-39 Hamada, Mihama-ku, Chiba, Japan, Choushimaru emphasizes in-house craftsmanship with daily fish preparation by skilled artisans and focuses on the restaurant segment of Japan's consumer cyclical industry, serving casual diners seeking premium yet accessible sushi experiences. In a key strategic expansion, the company established SUSHI-TEN USA Inc. as a joint venture in March 2024 with Royal Holdings Co., Ltd. and Sojitz Corporation, each holding approximately one-third equity, to launch sushi operations on the U.S. West Coast starting from California amid growing demand for localized Japanese cuisine; this tripartite alliance leverages Choushimaru's sushi expertise, Royal Holdings' restaurant management know-how and Sojitz's global networks to penetrate overseas markets previously limited to domestic operations.
