Nissui Corporation, is a marine products company based in Tokyo, Japan. Formerly known as Nippon Suisan Kaisha Ltd. from 31 March 1937 to 30 November 2022, it officially changed its name to its common abbreviation on 1 December 2022. The company was established as the fishery division of Tamura Steamship Company in March 1911 by Ichiro Tamura, a cousin of the head of the Fujita Zaibatsu. Its former headquarters, built in Tobata in 1929, is now an exhibit center. It has been listed on the Tokyo Exchange since 16 May 1949, when Japan's stock market was resumed after the Second World War. It is the only component of the Nikkei 225 index from the country's fishery sector. With 768 billion yen annual sales in FY2022, it is now the second largest commercial fishing and marine product procurement corporation in the country by revenue, only surpassed by the Maruha Nichiro Holdings. Its founding principles state 'A tap water supply system is exactly what marine products should be like in their production and distribution'. In 2005, the company divested its whaling fleet following controversy for its role in the modern global whaling industry. Wikipedia
