The yolk part of the white egg is not due to defects, but has scientific facts behind it. Quoting from Groovy Japan, on April 25, 2025, the egg whose yellow part is white is referred to as a commitment in Japan.

These cometsuya eggs are produced from poultry farms in Takeuchi in Hokkaido, Japan. The cometsuya name comes from the word come which means rice', and tsuya which means 'floating'.

The farm provides an explanation and some of the facts that cause the cometsuya egg yolk to be white. This happens because the laying hen feed is rice.

Generally, laying hens are given corn feed. However, this farm replaces it with pigment-free rice feed, which makes the egg's yellow color more pale and turns white and bright when heated.

Apart from being large, the laying hens at the farm were also given other foods to produce cometsuya eggs. Some of them are Hokkaido sea fish, raw rice denda, shell shells, and others.

Regarding whether cometsuya eggs are healthy or not, there has been no research to support this. However, the taste of the eggs remains delicious, such as eggs in general, the sensation is also a bit sweet and savory.

These cometsuya eggs are generally processed into boiled eggs. However, some people also process these eggs into food in the form of toiletries, as peddled at a restaurant called Shokudo Days.
