What Is Tomato Day?

October 10th is "Tomato Day" in Japan. The date comes from a wordplay on "to(10)-ma-to(10)" (tomato), and it was established by the National Tomato Processors Association. October is also Japan's month for promoting better eating habits and includes Sports Day, making it a month when interest in health rises.

A Nutrient-Rich Vegetable Enjoyed From Summer Into Autumn

Tomatoes are rich in nutrients, including lycopene, and are enjoyed both fresh and in a wide range of processed forms.

  • Origin: a simple, memorable wordplay directly matching the sound of "tomato" to "10, 10"
  • Purpose: to spread awareness of the tomato's nutritional value, delicious flavor, and potential as a processed food ingredient
  • A wide range of uses: beyond fresh tomatoes, they're widely used in processed products like tomato juice, ketchup, and canned tomatoes

Lycopene, the Source of the Red Color

Lycopene, the compound behind a tomato's red color, is known as an antioxidant. It is said to be absorbed more easily when tomatoes are cooked or eaten with oil.
