Every other page on this site tells you to keep a second supplier so your pricing stays honest. On this page that advice needs a warning attached, because three of the largest Asian distributors serving Chicago are owned by Japanese public companies, and the ownership is not obvious from the names on the invoice.
JFC International, whose Chicago distribution centre is in Hanover Park, belongs to Kikkoman. Kikkoman's own corporate site says it entered the Asian food wholesale business in 1969 by acquiring a management stake in the company that became JFC, and that the JFC Group now runs its wholesale business across 24 countries and regions. Yamasho, in Elk Grove Village since 1981, was acquired outright in December 2022: Takara Holdings published the filing, in which Mutual Trading acquired 100 percent of the shares issued and outstanding. Wismettac Asian Foods in Carol Stream traces to Nishimoto Trading, founded in Kobe in 1912, with the US company established in 1960.
There is one more turn of the screw. Golden Country, the largest genuinely independent house on this page, lists Kikkoman first among the lines it represents. So a buyer who moves part of an order off JFC to Golden Country for leverage is, on that part of the order, still buying the same brand. None of this is a reason to avoid any of these companies. It is a reason to know the answer before you build a buying strategy on a comparison that may not be one.
