Boiled Egg Day

Today, and February 1st annually, is Boiled Egg Day (ゆでたまごの日). 

Boiled Egg Day is a lighthearted food anniversary created by the Japan Boiled Egg Association, an organization based in Nakahara Ward, Kawasaki City. The group promotes the theme “Make every day a little happier with boiled eggs.”

The date February 1 was chosen through Japanese wordplay: 2 (ni) – 0 (wa/“egg”) – 1 (hito/“one”), suggesting that with just one egg, a dish can come together. It also marks the association’s founding date in 2019. The purpose of the day is to help more people appreciate the simplicity, nutrition, and versatility of boiled eggs. 

Eggs are often called a “complete food” because they contain high‑quality protein, vitamins, minerals, and healthy fats. When boiled, they can be enjoyed in many forms—soft‑boiled, hard‑boiled, seasoned, or used in salads and rice bowls. The association’s website shares tips for making perfect boiled eggs along with recipes for flavored eggs, dips, and more.
