Maruchan Seimen announces brand renewal for 15th anniversary

Maruchan Seimen is renewing its entire product series to mark its 15th anniversary. Under the theme ‘Noodles are everything,’ the brand aims to enhance its value by further pursuing authentic flavors through its patented ‘Nama-men Umai-mama’ manufacturing process.

The renewal, scheduled for release on September 7, 2026, features improved noodle textures that are smoother and more chewy. The soup varieties will also see enhancements using homemade dashi—simmered from pork bones, chicken carcasses, and vegetables—to create a more mellow and balanced flavor. The lineup will include six varieties: soy sauce, miso, umami salt, tonkotsu, tonkotsu soy sauce, and Japanese-style soy sauce chuka soba.
