Overview
Kojima Foods Co., Ltd. (コジマフーズ株式会社) is a Japanese food manufacturer headquartered in Minami-ku, Nagoya, Aichi Prefecture.

Its product range includes organic JAS-certified germinated brown rice, brown rice mochi, brown rice rice-packs, porridge (kayu) series, boiled beans, and multigrain blends. The company emphasizes careful ingredient selection, quality control and an organic JAS-certified factory.

History
Kojima Foods traces its origins to May 1948 (Showa 23), when the business was founded as a rice and grain enterprise. On March 28, 1953 (Showa 28), it was incorporated as Kojima Shoten, a limited partnership (合資会社小島商店), with capital of 500,000 yen, and began selling processed foods made from rice, grains and wheat. In April 1962 (Showa 37), capital was increased to 1.5 million yen. In November 1965 (Showa 40), the company was reorganized as Marutomi Co., Ltd. (株式会社まるとみ) and capital was increased to 2 million yen. In August 1971 (Showa 46), it was reorganized again as Kojima Beikoku Co., Ltd. (小島米穀株式会社) and capital was increased to 4 million yen. In April 1977 (Showa 52), capital was increased to 8 million yen, and a noodle and Japanese cuisine restaurant, "Eitaro," was opened in Midori-ku, Nagoya. The company's product development in brown rice foods began in earnest in the late 1970s and 1980s. In October 1979 (Showa 54), it developed brown rice mochi; in 1980 (Showa 55), it developed brown rice mugwort mochi, brown rice millet mochi, brown rice foxtail millet mochi, and brown rice rice-packs. In September 1985 (Showa 60), capital was increased to 16 million yen, and brown rice Gohei mochi was developed. On July 25, 1987 (Showa 62), the company changed its trade name to Kojima Foods Co., Ltd. (コジマフーズ株式会社) and closed the "Eitaro" restaurant. In July 1988 (Showa 63), it developed brown rice porridge and brown rice azuki porridge. In 1989 (Heisei 1), it developed brown rice pumpkin porridge, brown rice potato porridge, and brown rice cream. In March 1990 (Heisei 2), it developed germinated white rice 66. In 1991 (Heisei 3), it developed hie Gohei mochi, 100% kibi mochi, 100% awa mochi, kibi rice-packs, and kibi porridge. In 1993 (Heisei 5), it developed five-grain porridge and multigrain porridge. In 1995 (Heisei 7), it developed jitsu soba porridge and 100% buckwheat porridge (shirokayu). In 1996 (Heisei 8), it developed kine-zuki rice and boiled beans, and in November of that year, jitsu soba porridge and silken cream. In August and September 2000 (Heisei 12), it developed active germinated brown rice and germinated brown rice rice-packs. In May, June and July 2001 (Heisei 13), it developed germinated white rice, baby rice (brown rice cream series), germinated brown rice porridge, germinated brown rice rice-packs (gomoku, azuki, multigrain), and germinated brown rice mochi, and launched its website. The company's philosophy is rooted in the experience of the previous generation of the founding family, who reportedly cured chronic kidney inflammation through a six-month brown rice dietary therapy. This personal experience led to a commitment to developing brown rice-based retort foods that are both nutritious and easy to eat. The company operates an organic JAS-certified factory and emphasizes quality control and ingredient selection, including the use of natural salt "Umi no Sei" in its porridge products. Its main business partners include Ohsawa Japan, Muso, Bio Market, Natural House, Marushima Junsei Shokuhin, and the Kyushu Natural Food Cooperative. As of the 2020s, the company continues to develop and sell brown rice-centered products, with recent notices regarding price revisions and product discontinuations.
