Is the traditional Japanese seasoning order 'Sa-Shi-Su-Se-So' outdated? Introducing the Reiwa era's new standard 'V-S-S'! The culmination of vinegar researcher Akiko Iwama's 365-day vinegar journey.

Shufunotomo Co., Ltd. will release the book 'Vinegar-Pushing Recipes' on Friday, May 29, 2026. This book proposes the new Reiwa-era seasoning standard 'VSS (Vinegar, Sugar, Salt).' It is a bible overflowing with 'vinegar love,' condensing the profound charm of vinegar—which balances the mind and body—into one volume through 100 exquisite recipes and a guide to 33 breweries across Japan. In this book, instead of the traditional Japanese seasoning order 'Sa-Shi-Su-Se-So,' the author proposes a unique method called 'VSS,' where you start seasoning with vinegar. V (Vinegar) brings out the flavor of ingredients, S (Sugar) adds sweetness to the acidity, and S (Salt) finalizes the taste. Ms. Iwama herself has experienced a reduction in body fat percentage by consuming vinegar daily, and the book covers health and culinary benefits based on scientific evidence. From surprising recipes like adding vinegar to curry or milk, to a guide to breweries nationwide, the book introduces the full charm of vinegar.
