Doyo no Ushi no Hi - Japan’s traditional “Eel Day” marks a special time during summer to restore energy, beat the heat, and recharge your health. In 2025, this seasonal celebration falls on July 19 and July 31, and Unatoto Singapore invites you to savour authentic Japanese eel dishes at wallet-friendly prices.

But why is Doyo no Ushi no Hi so important? What’s the right way to enjoy eel? And where can you experience this tradition in Singapore? This guide reveals it all.

Origins of Doyo No Ushi No Hi

Doyo no Ushi no Hi (土用の丑の日) refers to the “Day of the Ox” during Doyo – the 18-day period before the beginning of autumn in the traditional Japanese calendar. This is when summer hits its peak heat, and the Japanese turn to Unagi (grilled eel) to fight off fatigue and restore stamina.

Dating back to the Edo period, the scholar Gennai Hiraga encouraged eel restaurants to promote eating unagi on this day, claiming it boosts health. The custom caught on and became a yearly tradition still celebrated across Japan.

Eel – Japan’s Summer Superfood

More than just delicious, unagi is packed with nutrients: rich in vitamins A, B1, B2, D, protein, and omega-3 fatty acids. Thanks to its high nutritional value, eel is the perfect summer pick-me-up to:

Boost immunity
Replenish energy
Help the body recover from summer exhaustion

Doyo no Ushi no Hi isn’t just cultural, it's a smart, science-backed way the Japanese care for their health during the hottest time of year.
