A celebration of Sanko Seika
Today, and March 5th annually, is Sankō Day 三幸の日, a day commemorating Sanko Seika. Sanko Seika are a Niigata based company known nationwide for rice crackers and snacks. They chose March 5th as their celebration day because 3/5 can be pronounced as "Sanko".
Founded in 1962, Sanko Seika built its reputation through long‑selling products such as Yuki no Yado, Niigata Shikomi, Parinko, Cheese Almond, and Kokutō Milk. These snacks have become household favorites, thanks to their comforting flavors and nostalgic presence in Japanese homes. Their "Yuki no Yado", pictured, are a favorite in my house and have always been well received when I buy them as souvenirs to bring home to Ireland.
The company established this anniversary in 2009. They also have other anniversaries in the year for their individual snack lines. Do you buy their products? Do you have a favorite?

Former nickname was "Saitama". Changed it to save confusion on place review posts! Irish, 20+ years in Japan! I also write on my personal website: insaitama.com
