Cake Day (Kēki no Hi)

What Is Cake Day?

January 6th is "Cake Day" (Kēki no Hi) in Japan. The date commemorates January 6, 1879, when a Western confectionery shop in Ueno, Tokyo, ran what is considered Japan's first advertisement for cake in a newspaper. At the time, the word "cake" itself was still unfamiliar, making this a symbolic moment marking the spread of Western food culture into Japan. The date also happens to coincide with Epiphany in Christian tradition — a day with a deep, real connection to the custom of eating special cakes in countries such as France.

The Historical Spread of Cake in Japan

In fact, cakes in the Meiji era looked quite different from the elaborately decorated cakes of today.

• The First Advertisement: Yonezu Matsuya in Ueno — the predecessor of today's Tokyo Fugetsudo — placed a prominent newspaper ad for the "manufacture and sale of Western confectionery cake." This is considered one of the earliest known uses of the word "cake" in Japan.
• What Cake Actually Was Back Then: Rather than the cream-heavy cakes of today, the cakes of that era were closer to baked goods like pound cake or castella — a high-end, shelf-stable confection.

The Worldwide Tradition of "January 6th Cake"

January 6th is, in fact, tied to religious and cultural customs of eating specific cakes around the world.

• Galette des Rois: In France, people eat a pastry called "galette des rois" (king's cake) on this day. Whoever finds the small porcelain figure, the "fève," baked inside is crowned king or queen for the day and said to enjoy good luck for the rest of the year.
• Roscón de Reyes: In Spain and Latin America, families share a crown-shaped, donut-like sweet bread on this day — a living tradition that celebrates the start of the new year.

Interesting Facts About Cake

• Shortcake Is a Japanese Original: The classic Japanese shortcake — sponge cake layered with whipped cream and strawberries — was actually developed by the founders of Fujiya, tailored to Japanese tastes, making it a uniquely Japanese evolution of the cake.
• The "Uncuttable" Symbolism of Cake: Cakes are often made round (a shape associated with harmony and completeness in Japan), which is why they're chosen as a symbol for celebrations — and cutting one to share is seen as "sharing happiness."
• The Christmas Connection: The Japanese custom of eating cake on Christmas became firmly established thanks to confectionery makers' marketing campaigns from the mid-Showa era onward.
• The World's Oldest Cake: Ancient Egyptian wall paintings depict early forms of cake made with honey and fruit — humans have been enjoying sweets on special occasions for thousands of years.
• A Secret in the Name: The word "cake" comes from the Old Norse word "kaka," which originally referred to something more like a flat bread.
