JJapan What does the “+T4” mean next to a best by date on packaged food? May 8, 2025 I'm sorry if this isn't the right place for this. The date reads 25.2.18+T4 I know it is past the best by date but what does the +T4 mean? by nonameoatmeal Tags:Japan 1 comment Is it a Koikeya brand product? If so, [the “+T” defined which factory it was made in](https://koike-yafaq.dga.jp/dispImage.php?id=127). Not sure about the “4” part. I wouldn’t be surprised if other companies used similar notation.
