Savor Unagi Eels on the Midsummer Day of the Ox!

In addition to sushi and tempura, unagi (freshwater eel) stands out as one of Japan's most beloved culinary delights. Visitors might not know that there are specific days in Japan when consuming eel is considered auspicious. This article will explore some distinctive Japanese eel dishes and customs.

Why Do Japanese People Indulge in Eels During Summer?

Eels can be relished throughout the year, but in Japan, they are particularly favored as a "stamina-boosting food" during the summer. The reason behind this lies in the fact that the high temperatures and humidity prevalent in Japan during the summer often lead to people experiencing fatigue. In order to get rid of this fatigue, many of them actively consume nutritious foods, of which eel offers an abundance. They contain protein, which aids in muscle development, as well as vitamin A, which enhances immunity. Moreover, they boast vitamins B1 and B2, known for their fatigue-relieving properties, along with vitamin E, which exhibits potent antioxidant effects. Additionally, eels provide a rich source of zinc, calcium, iron, and more! Hence, they have gained renown as an ingredient that helps individuals recover from summer fatigue.

What Is “Doyo No Ushi No Hi” (Midsummer Day of the Ox)?

In Japan, eel is frequently enjoyed during the summer, but there is a unique tradition of savoring them specifically on "Doyo no Ushi no Hi" (the Midsummer Day of the Ox). Doyo no Ushi no Hi is a Japanese custom rooted in the Chinese concept of "Yin-Yang and the Five Elements," which explains that the world is composed of five elements: wood, fire, earth, metal, and water.

Ancient people believed that malevolent spirits emerged during seasonal transitions and devised various customs to seek good health. Particularly during the summer Doyo period, when heat and humidity made illnesses more prevalent, people started safeguarding themselves by consuming nourishing food. In the Edo period (1603-1869), the trend of indulging in eel on the summer Doyo no Ushi no Hi gained immense popularity and has endured as a tradition to this day. Notably, in the year 2023, there will be only one summer Doyo no Ushi no Hi, occurring on July 30.

Typical Japanese Eel Dishes

Eels are enjoyed in various countries across the globe, but they are often smoked or stewed, which differs from Japanese eel dishes. Here are some favored eel dishes in Japan.

・Kabayaki
A dish wherein unagi, anago (conger eel), and other slender fish are meticulously prepared by removing the bones, skewering them, and grilling them with a sweet and salty soy sauce-based "tare" glaze. When relishing this delicacy, the skewers are often removed for ease of consumption. The charcoal grilling infuses a captivating smoky aroma that enhances its already delectable taste. It's worth noting that the preparation process for unagi for kabayaki differs between the Kanto and Kansai regions. In Tokyo, the eel is opened from the back, threaded onto bamboo skewers, steamed, and then expertly grilled while being basted in sauce. The steaming process removes excess fat, ensuring a moist and tender texture. On the other hand, in the Kansai region, the eel is opened from the belly, pierced with metal skewers, and slowly grilled. The longer grilling time imparts a delightfully crispy texture to the eel.

・Hitsumabushi
Hitsumabushi, a renowned specialty of Nagoya, showcases a delightful combination of rice served in a "hitsu" rice container with delectable strips of unagi kabayaki on top. Those trying Hitsumabushi can enjoy the dish in three different ways. First, they should divide the rice into four equal portions using a rice scoop. They can enjoy the first portion in its pure form, directly in a bowl. For the second serving, they can adorn it with an array of condiments such as chopped green onion, wasabi, seaweed, and more. This accentuates the rich flavor of the eel and gives it a refreshing taste. The third serving incorporates these condiments along with a drizzle of "dashi" (Japanese soup stock). Finally, the fourth serving can be enjoyed according to personal preference.
