Celebrated on 07/07/2026

Quick Fact

National Koi Day, celebrated on July 14th, honors the vibrant ornamental fish that symbolize good fortune and perseverance in Japanese culture. Interestingly, koi can live for over 50 years and have been known to recognize their owners, often eating from their hands.

Origins and Establishment of National Koi Day

National Koi Day was established in 2020 by a coalition of koi breeders, pond enthusiasts, and Japanese cultural organizations to celebrate the beauty and symbolism of koi fish. The date July 14th was chosen because it coincides with the peak of summer when koi are most active and visible in ponds. The holiday aims to educate the public about koi care and their significance in Japanese art and folklore.

Evolution and Modern Commemoration

Since its inception, National Koi Day has grown through social media campaigns using #NationalKoiDay, where enthusiasts share photos of their prized fish. Many public aquariums and Japanese gardens host special viewing events, and online retailers offer discounts on koi-related products. The day has also become a platform for promoting conservation of wild koi varieties in Japan.
