This is a very popular all-purpose Japanese seasoning from Kamada Soy Sauce. With just one bottle, you can make udon noodle soup, rolled omelets, steamed egg custard (chawanmushi), clear soup, oden broth, simmered dishes, and more. It's incredibly versatile. The concentrated sauce is used in small amounts and diluted, so this size will last a while. Expiration Date: December 2026 Will be shipped in a recycled cardboard box. Price is not negotiable.
